Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Simulate a propagation technique for wild red sage root seedling, comprise following step:
The first, cultivate the good hereditary factor of the wild red sage root
Traditional Chinese medicine elite germplasm, is that good gene are integrated into the phenotype on the former plant community of a kind of traditional Chinese medicine, has relative inheritance and the relative uniformity on major traits, and the quality of germplasm plays conclusive effect to quality of medicinal material and output.First to pay attention to the cultivation of improved seeds, as the germplasm without good, even if having desirable natural environment and culture technique, also cannot change its original economic characters and curative effect, good " plant melon and obtain melon; plant beans and obtain beans " that common saying is said, this language simple and image, the not broken scientific meaning of rich top Piao.Therefore, cultivating good salvia hereditary factor, is to implement the key that the wild red sage root green crude drugs of simulation is produced.
Any improved seeds all should often impurity elimination pure keeping, the deterioration of variety of taking measures in time to prevent.Otherwise Deng variety hybriding degradation, purificate and rejuvenate after serious, that just gets twice the result with half the effort again.Should, according to the reason of variety hybriding degradation, take appropriate measures.
1) good wild red sage root kind is selected good strains in the field for seed and is educated: at red sage root Proterozoic, select blade profile, flower type, cane and underground rhizome color, the red sage root that plant growth form is consistent on the ground, selection is infected without damage by disease and insect, tanshinone IIA content >=0.4%, the wild good species strain of tanshin polyphenolic acid B >=7%, set up the wild Salvia miltiorrhiza Growth environment of simulation and foster garden, foster observation;
2) the secondary individual plant selection of wild good species strain: foster in garden at the wild red sage root of simulation of setting up, selection meet feature, characteristic, the kind strain of the raw red sage root kind in open country healthy and strong, best in quality, without the fine individual plant of damage by disease and insect, secondary individual plant selection is carried out in tanshinone IIA >=0.4%, content of danshinolic acid B >=7% aspect, again selected individual plant is migrated to the garden of fostering, plant garden and foster;
3) foster in the garden of fostering, plant garden: the fine individual plant in fostering garden is classified, transplanted, carry out feature discriminating, especially thousand grain weigth, can be used as the reference index of weighing seed quality and maturity, and the good salvia plant seed list optimizing is received to single Tibetan, number in order, as the material of seed selection new varieties, enter the strain nursery garden of fostering and foster, for the more convenient contrast of carrying out controlled observation and quality and yield, can also carry out the setting of community area, community area 5m
2, row, spacing in the rows are 40 * 30cm, one strain of every cave.
As can be seen from Figure 1: the thousand kernel weight of repetition 1 is 1.49169; Repeating 2 thousand grain weigths maximum, is 1.64589; Repeating 3 thousand grain weigths secondly, is 1.55769; Repeating 4 thousand grain weigths minimum, is 1.36779.The thousand kernel weight mean value repeating is 1.51579, repeat to have most flat seeds in 4 seeds, may due to this repeat in salvia seeds have more jejune causing, visible conventional red sage root kind thousand kernel weight is greatly about 1.69 left and right.
The good genic process of cultivation of above step 1)-3) mainly carrying out, in this process, roguing is the measure of avoiding occurring in plantation, results, storage mechanical admixture.Seedling Stage at medicinal plant is pulled out the hybrid that is different from breeding, retains the pure strain that meets breeding feature, characteristic.In addition will note arranging crop rotation, avoiding different cultivars of the same race is front and back stubble, in order to avoid do after anything left from previous crops plant to mix.
In order to keep good strains of seeds, artificially breeding not only can be removed hybrid strain, and has the effect of consolidating and improving good characteristic.The method of seed selection and standard are that feature, characteristic and the active ingredient according to medicinal plant is determined, and the method for seed selection has individual plant selection, mixes seed selection and improvement mixing seed selection.Cultivate new varieties and stock breeding and all should adopt this selection, but their object is different, what the former selected is to surpass former kind, reaches the object of cultivating new varieties; The latter is purification and rejuvenation, and object is the Optimality that retains former kind.
The second, be below the wild red sage root seedling breeding environment of simulation, breed and be close to wild red sage root seedling.
4) the wild red sage root seedling breeding environment Breeding base of simulation is set up in employing: around radius 5km is interior without appointing river pollution source to simulate the selection of wild red sage root seedling breeding base, air quality meets GB3095-1996 first quality standard, height above sea level is 250m-400m, natural vegetation 40%-60%, the gradient is 10-20 degree, nursery stage precipitation mid-June-mid-July should account for 20% left and right of annual precipitation, temperature is more than 30 ℃, light application time is more than 9 hours, shading rate≤65-70% in after planting 11 days, irrigation water meets GB5084-92 first quality standard, soil is with sandy red, yellow soil, meet GB15618-1995 quality standard.
Different temperature has different impacts to the sprouting of salvia seeds.Salvia seeds under field conditions (factors) germination rate is low, generally only has 30%-40%, and it is uneven to emerge.Germination vigor and germination rate are as following table 1 under condition of different temperatures for salvia seeds, and salvia seeds is all with best, wherein the highest to repeat H percentage of seedgermination between 20 ℃-30 ℃, under 20 ℃, 25 ℃ and 30 ℃ of conditions, reach respectively 67%, 71% and 71.3%; Repeat 3 percentages of seedgermination and take second place, under the same terms, be respectively 58.7%, 65% and 65%.
Table 1 different temperatures salvia seeds germination rate
Also there is impact in different seedbed namely soil on germination rate, from following table 2, can find out: different repetition salvia seeds germination vigor under sandy loam and clay condition is lower, germination required time is longer, because salvia seeds is little, contained nutriment is few, a little less than plumule pushes up native ability, sandy loam and clay condition can provide part nutrient component again simultaneously, are conducive to improve percentage of seedgermination.By above-mentioned experiment, examine and can draw: salvia seeds under sandy loam condition germination rate and germination vigor all higher than under clay condition, this has also confirmed from an aspect, the main producing region of the red sage root is the soil condition in the genunie medicinal materials place of production particularly, mostly generally all is the sandy loam on mountain area or hills.
The different seedbed of table 2 salvia seeds germination rate
The impact of differing texture soil on abundant red sage root yield traits, as shown in Table 3, different soils quality is to Salvia miltiorrhiza Growth development impact significant difference.Single plant yield sand improves respectively 14.51 %, 37.31 % compared with loam, clay; Individual plant root number, clay number is maximum, and sand is minimum, and clay and sand root number difference reach significance level.This shows, sand is conducive to the raising of red sage root output, this may be because the red sage root be phreatophyte, well developed root system, layer depth thick, open-textured sand in native land is conducive to root growth, poor because of sand preserve moisture and fertility ability but then, may have influence on the number of root number, but not remarkable with loam difference.
The impact of table 3 different soils quality on abundant red sage root yield traits
The impact of differing texture soil on abundant effective component in red sage content, table 4 shows, sand effective component in red sage content is the highest, and tanshin polyphenolic acid B, tanshinone IIA content reach respectively 8.87 %, 0.30 %, loam and clay be respectively 4.36 %, 0.24 % and 4.85 %, 0.28 %.
Table 4 different soils quality active constituent content
5) use with fertilizer: before whole ground, use the health fertilizer 112.5kg-450kg that becomes thoroughly decomposed for every 1 hectare, spread fertilizer over the fields uniformly on the ground wholely; Simulating the wild red sage root base of growing seedlings should plough shallowly, and tilth is in 20cm, then ploughs plain grinding thin; Simulate the wild red sage root base 300cm that grows seedlings and play high furrow, high furrow clear span is 270cm, furrow width 30cm, the then thin leveling of rake.
The impact of different fertility on Index of The Healthy Seedlings, comprises the variable effect to red sage root seedling fresh weight, dry weight, the impact on red sage root plant height, stem thickness, and the impact on red sage root shoot root number, fibrous root number, specific as follows:
Different Fertilization amount (representing with (F1) 112.5 kg/hm2, (F2) 225 kg/hm2, (F3) 450 kg/hm2) is established respectively in test, and July 12 grew seedlings on the same day, three processing of each factor, and each processes three design iterations.
Prior to seeding, be all made into long 2.2 m, the little furrow of wide 0.6 m, broadcasting sowing front every furrow, to engrave flat rake thin, broadcasts sowing at the bottom of rear flat rake concora crush one time, the about 0.5cm of rear earthing, overhead the horizontal coverage shading net of about 0.5m, evenly sprays and irrigates the water of growing seedlings in the above, shades 30 days.Once, each every furrow sample 6 strains in sampling in every 10 days, and every Index of The Healthy Seedlings is surveyed in totally 18 strains, and numerical value is averaged.
the dynamic changes of fresh weight of red sage root seedling under different fertility,as can be seen from Figure 2, after September 7, the fresh weight difference of three processing of Different Fertilization amount starts to widen, once in 9 months, last ten-days period F2 processing was also greater than F3 processing, F3 processing fresh weight in whole seedling growth process accounts for one and has superiority, in mid or late October, reach maximum, F1 processes and in mid-October, has also surpassed F2 processing.
From Fig. 3, observe, with Fig. 2 comparison, have two contrary broken line variation tendencies, the one, fresh weight is processed and is greater than F3 processing at mid or late September F2, can dry weight more contrary, another be that fresh weight Fl processes and after mid-October, surpassed F2 processing, can dry weight be relatively that F2 processes and is greater than F1 always and processes.From these 2, can draw, large fertilizing amount process mid or late September to early October dry weight and fresh weight of plant seedlings larger, this stage illustrates that the synthetic and accumulation of thousand materials needs more inorganic elements, fertilising contributes to dry weight to increase more, why the dry weight of another F2 can catch up with the dry weight of F3, this be also because F2 process the support just in time mate at its fertility level of later stage its plant fresh weight form, dry weight and fresh weight of plant seedlings is larger, unlike F3 because later stage fresh weight is excessive, fertility is processed not as good as F2 on the contrary, dry weight and fresh weight of plant seedlings ratio is on the contrary lower than F2, so can catch up with.Also have a bit, why F2 processes in 9 months last ten-days period to mid or late October fresh weight and is declining, and dry weight is but rising always, this with explain above from extroversion growth, to turn to storage transhipment be that master's reason is identical.
the dynamic change of red sage root seedling plant height under different fertility,from Fig. 4 observation analysis, Different Fertilization amount is processed does not have anything significantly to affect on the final plant height of seedling, and three lines are weave in all the time, removes sampling error, cannot analyse what rule, and what impact the plant height that visible fertilizer treatment is grown seedlings on the red sage root does not have.
From Fig. 5, observe the thick Trendline of stem, except processing, F2 about mid-September is greater than F3 processing, substantially be all on F3 residence each period later, F2 is placed in the middle, under F1 occupies, but obvious, the stem rough error that F2 and F3 process is apart from little all the time, and three different fertility that Here it is are processed the thick action rule changing of stem.
The dynamic change of red sage root shoot root number under different fertility, in Fig. 6, show, the root number of three different fertility processing has obvious regularity, substantially on F2 residence, F3 is placed in the middle, and under F1 occupies, September, early and middle ten days F2 root number started to surpass in reverse F3 processing after visiting the end, hold a safe lead later, and illustrate that high fertilizing amount does not promote root number to increase.
under different fertility, the fibrous root of red sage root seedling is counted dynamic changefig. 7 shows that F2 processes fibrous root number and stablizing among increase always, F3 processes and after early September, starts a decline, and among a kind of variation being in sharply of fibrous root number that F1 processes, minimum to the fibrous root on September 9 at most from the fibrous root on August 30, again to September 19 at most, then, at the bottom of the spy on September 29, the variation of visible fibrous root quantity is big.It be because this processing fertility is abundant that F3 processing starts to decline after early September, hindered _ stopped increasing fatting up the absorption with mineral element of fibrous root, and the sharply variation of the fibrous root number that F1 processes can be regarded as, the seedling that F1 processes is always among a kind of inharmonic growth relationship, in its growth conditions, only outside a Fertilization Level condition shortcoming, other raw elongate member are all quite superior, so when overground part Fast Growth, promote fast increasing of underground part fibrous root amount, to draw nutrient, principal contradiction goes underground like this, Deng underground part situation, transform, oneself is neglected the growth of overground part, so growth contradiction proceeds on the ground, underground life one length is absorbed in again stagnation and even falls back, like this, a kind of like this, not only fast but also a little turned round and look at high fast-growing one under life one long status that head do not turn round and look at pin and grown, just there is the sharply variation of fibrous root number above.
the index dynamic change in strong sprout of red sage root seedling under different fertility,from Fig. 8 see except from September early and middle ten days to strong sprout mid or late September index F2 oneself surpass F3, the gap of other periods F2 and F3 is also little, just slightly lag behind the highest fertilizing amount level, the red sage root is usingd root as the medicinal plant of gathering in the crops object as a kind of, so very one of free-revving engine of strong seedling cultivation is exactly that to cultivate root of hair many, the strong sprout of well developed root system, in conjunction with the comparison of root number and fibrous root number above, F2 processes all has best advantage, comprehensive factors, can show that F2 treatment effect is optimum, be applicable to cultivating strong sprout.
6) sowing: it is the best sowing time of the red sage root that the sowing time is selected mid-June-July, every 667 ㎡ seeding quantitys are 2.5kg, before type of seeding sowing, in every 2.5kg salvia seeds, add the base fine earth 7.5kg that grows seedlings to mix even, be sprinkling upon uniformly in the soil on high furrow, then with the waddy rolling of a diameter 20cm, suppress, also available Hsinchu besom is patted the seed spreading in soil, and salvia seeds is fully contacted with soil.
the impact of different seeding quantity on Index of The Healthy Seedlings, is mainly the impact on red sage root seedling fresh weight, the impact of dry weight, the impact of plant height and stem thickness, the impact of shoot root number and seedling yarn number.test is established respectively three different seeding quantities (with (S1) 30 kg/hm
2, (S2) 60 kg/hm
2, (S3) 90 kg/hm
2, represent), July 12 grew seedlings on the same day, and each processes three design iterations.Prior to seeding, be all made into long 2.2 m, the little furrow of wide 0.6 m, broadcasting sowing front every furrow, to engrave flat rake thin, broadcasts sowing at the bottom of rear flat rake concora crush one time, the about 0.5cm of rear earthing, overhead the horizontal coverage shading net of about 0.5m, evenly sprays and irrigates the water of growing seedlings in the above, shades 30 days.Once, each every furrow sample 6 strains in sampling in every 10 days, and every Index of The Healthy Seedlings is surveyed in totally 18 strains, and numerical value is averaged.
red sage root seedling dynamic changes of fresh weight under different seeding quantity, as can be seen from Figure 9, after September 7, the fresh weight of three different seeding quantity processing starts to occur larger differentiation, and S1 processes with S2 processing beginning and sharply rises, and S2 enters again the process that declines slowly subsequently.And S3 has a larger decline process, then entering one increases process slowly.The decline process of S3 can be thought, when seedling enters fast growing period, because the density that S3 processes is excessive, the water of striving between seedling is striven fertilizer to strive space serious, cause principal contradiction to become the mutual survival of the fittest, cause poor growth, negative influence mutually, bottom a few fore-telling sheet early ageing, fresh dry weight declines and even falls back simultaneously.After this fierce growth competition decided the winner, sap one's vitality, so win the part increase phase that enters fresh weight that also just slow J overflows.
the dynamic change of red sage root seedling dry weight under different seeding quantity,from Figure 10 and Fig. 9 comparison, except S2 mid or late September to October early and middle ten days dry weight Trendline contrary with fresh weight Trendline, also have S3 to process contrary in the dry weight and fresh weight of plant seedlings Trendline of mid or late October to early November, showing as the now export-oriented growth of seedling turns to and take nutrient component and stock as main, the nutriment of the lower blade of some old and feeble yellows accelerates to seedling interior shifting, accelerate its aging death, so plant fresh weight declines, on the other hand, although fresh weight declines, but dry matter composition is mostly got up by transhipment storage, so dry weight has increased on the contrary.
the dynamic change of red sage root seedling plant height under different seeding quantityfrom the plant height polygram of Figure 11, can find out, the processing of growing seedlings of three different seeding quantities, aspect plant height, difference is little, S1 processes at the minimum in plant height always in early stage, due to rich water and growing space factor, make S1 process the peak of having the advantage again at later stages subsequently, the plant height advantage of S2 is greater than S3 always and processes.
The thick dynamic change of red sage root seedling stem under different seeding quantity, on the thick polygram of stem of Figure 12 can go out, the processing of growing seedlings of three different seeding quantities, stem thick aspect difference also little, that on S1 residence, S2 S3 stem placed in the middle is slightly minimum substantially always, before early or mid September, the thick broken line of stem of three processing is almost overlapping, along with after S1 and S2 Acceleration of growth, the thick increment of stem is obvious, and S3 stem " falls, between visible plant, also has struggle for existence; and huge in-fighting in struggle, unexpectedly the thick waist of stem has also been attenuated slightly on the contrary one.The visible red sage root is in cultivating process in strong sprout, and suitable seeding quantity is most important.
the dynamic change of red sage root shoot root number under different seeding quantity,as can be seen from Figure 13, the root number that S3 processes is minimum, and in the October 19 of transplanting, oneself reaches the level that S1 processes to the root number of S2 substantially in left and right, but Sl processes because seeding quantity is little, in addition emergence rate is low, and the commercial seedling amount of per mu yield is too little, loses the meaning of strong seedling cultivation.
red sage root seedling fibrous root number dynamic change under different seeding quantity,by Figure 14 reflection, drawn, three different seeding quantities are grown seedlings very violent in the dynamic change of fibrous root number, three processing have super phenomenon mutually at different times, it is not difficult to find after careful observation, in fact just the fibrous root dynamic change that S3 and s1 process is violent, the dynamic change broken line that S2 processes is milder, this is that the unreasonable group structure of being grown seedlings by S3 and S1 two processing causes in fact, S3 processes the large promotion of colony in early stage and sends out fibrous root, later stage, colony was large, hinder and send out fibrous root, S1 processes the little obstruction of colony in early stage and sends out fibrous root, and fibrous root is sent out in the little promotion of later stage colony.For why S1 mid or late September to October early and middle ten days fibrous root number have the process that sharply declines, perhaps be to be larger 2 grades of roots because some fibrous roots are grown on the one hand, be that other fibrous roots are degenerated because supply with 2 grades of roots on the other hand, moreover be exactly because the group structure that S1 processes is too small, along with mercury dropped is very fast, day and night temperature strengthens, and causes ground temperature to decline and accelerates, and fibrous root root of hair is slow, new fibrous root growing amount, not as good as the old and feeble amount of degradation of the existing system of fibrous root, causes total fibrous root number to accelerate on the contrary to reduce.
red sage root seedling index in strong sprout dynamic change under different seeding quantity, from Figure 15, strong sprout index variation diagram in can find out, after September 7, strong sprout, index started sharply to break up, S1 holds a safe lead, it is top between two parties that S2 processes, S3 processes and significantly lags behind the above two.
the impact of different sowing dates on Index of The Healthy Seedlings is mainly to exert an influence to seedling-growing time and growing of regularity and seedling.three different sowing dates (with representing on (Tl) June 30, (T2) July 12, (T3) July 29) are established respectively in test; 7.12 sowings, by three processing of each factor, each processes three design iterations.Prior to seeding, be all made into long 2.2 m, the little furrow of wide 0.6 m, broadcasting sowing front every furrow, to engrave flat rake thin, broadcasts sowing at the bottom of rear flat rake concora crush one time, the about 0.5cm of rear earthing, overhead the horizontal coverage shading net of about 0.5m, evenly sprays and irrigates the water of growing seedlings in the above, shades 30 days.Once, each every furrow sample 6 strains in sampling in every 10 days, and every Index of The Healthy Seedlings is surveyed in totally 18 strains, and numerical value is averaged.
The impact of different sowing dates on abundant red sage root seedling-growing time and regularity, as shown in Table 5, it is all 7 d that T1, T2, T3 process seedling-growing time, process and emerge early, and the regularity of emerging is high compared with T4, T5, T6.Show after seed collection, grow seedlings more early, effect is better.
The different seedling raise periods of table 5 situation of emerging
Note: neat (emergence rate >=90 %), slightly irregular (75%≤emergence rate < 90%=, irregular (emergence rate <75 %).
The impact of different seedling raise periods on abundant red sage root seedling development, specific as follows:
(1) impact on plant height
Figure 16 shows, the seedling that different seedling raise periods bring out, between plant height, difference reaches utmost point significance, wherein with T2, be treated to the highlyest, reach 26.7 cm, all the other date of seeding seedling plant height on a declining curve with the postponement of sowing time, T1, T3 process respectively and process and differ 4.5 % and 11.2 % with T2, T4 processes with T2 and processes and differ 32.2 %, and T5, T6 process average plant height and be respectively 7.7 cm and 4.9 cm, and it is respectively 28.8 % and 18.4 % that T2 processes that T5, T6 process.
(2) impact on the total leaf area of individual plant
By Figure 17, found out, between T1, T2 process, difference does not reach utmost point significance, and between other date of seeding, all reaches utmost point significance level, and it is maximum that wherein T3 processes the total leaf area of individual plant, and T1, T2 process and differ respectively 8.8 % and 6.9 % with it.This may be withered relevant with the part of T1, T2 processing blade.T3 processes than T4 and processes and exceeded 36.2%, and T5, T6 processing is respectively 30.0 % and 13.6 % that T3 processes, and this species diversity may be spent late causing by the sowing time.
(3) impact on root growth
As shown in Table 6, the different seedling raise period seedling maximum root diameters trend that tapers off, wherein T1, T2, T3 processing and T4, T5, T6 process between difference reach utmost point significance level, between T4 processes with T6, difference reaches utmost point significance level, between other processing without significant difference.This shows, T1, T2, that T3 processes seedlings root is comparatively sturdy.
Maximum root is long, and it is the longest that T1 processes, and and other date of seeding between difference reach utmost point significance level; T6 processes and has utmost point significant difference between other date of seeding, and T3 and T5 also reach utmost point significance level between processing.
The total radical of individual plant, T2 processes at most, and T1 processes and takes second place.Propping up radical is also that T2 processes at most, and T5, T6 processing does not have supporting root.Radical is many, is more conducive to surviving of red sage root seedling when transplanting, and haves laid a good foundation for obtaining higher output.
The comparison of the different seedling raise period root of table 6 proterties
Note: significance test is Duncan duncan's new multiple range method, alphabetical identical person indicates without significant difference, alphabetical different persons represent to reach 5 %(lowercases), 1 %(capitalization) significance level, lower with.
(4) impact on abundant red sage root Seedling Biomass
Different seedling raise periods affect large (table 7) to red sage root seedling overground part fresh weight, it is maximum that T2 processes seedling overground part fresh weight, and T1 processes and takes second place, other trend that tapers off, between T1, T2, T3 processing and T5, T6 process, difference reaches utmost point significance level, electrodeless significant difference between other processing; The rate of giving money as a gift of overground part is successively successively decreased successively by seedling raise period; Underground part fresh weight and the root rate of giving money as a gift changes with fresh weight variation on the ground similar.
The different seedling raise period Seedling Biomass of table 7 change
(5) dynamic change of the abundant red sage root seedling leaves growth of different seedling raise periods
Figure 18 shows, the seedling leaves growth that T1, T2, T3, T4 process is obviously processed growth fast compared with T5, T6, and in front four dates of seeding, the growth of seedling leaves presents the difference of the speed of grow with the priority of seedling raise period, and the seedling leaves that T1 processes is grown the fastest.In growth of seedling initial stage to mid-August, there is a blade rapid growth phase, after mid-August, be notch cuttype and increase;
As shown in figure 18, after at the beginning of 9 months, T2 processing leaf growth speed is slow, lower than T3, T4, process, this may to process the growth branch of underground part root relevant with T2, the growth that T5, T6 process seedling leaves obviously lags behind always, and the priority of visible seedling raise period has larger impact to the growth of seedling overground part blade.
7) set up the wild red sage root of simulation and breed growing environment:
(1) play staking out: every 2.5m plays the little staking out of the Φ 4-7cm that 35cm is high in the furrow of base, in furrow top rail, takes a long 3.1m, the bamboo bar of Φ 3cm-5cm, and by bamboo bar tying up in little staking out tightly, bamboo bar is apart from ground 30cm;
(2) cover net: select the herding with sunshade net of shading rate 65-70%, and will herd with sunshade net and ride over uniformly on bamboo bar, with restricting herding with sunshade net tying up in staking out tightly, affect shaded effects with Anti-blow-open.
Different seedling raising mannerses is analyzed as follows on the impact of red sage root seedling:
impact on plant height, leaf area and root proterties
Table 8 shows, seedling leaf area and the longest root that sunshade net covers are thick, and all the utmost point is significantly higher than wheat straw covering; Plant height, wheat straw covers the utmost point and is significantly higher than sunshade net covering; The longest root the two without difference.This shows that sunshade net covers to grow seedlings and is conducive to growth of seedling.
The impact of the different seedling raising mannerses of table 8 on seedling acrial part and root proterties
impact on abundant Salvia miltiorrhiza Growth
Table 9 is known, and on the ground, underground fresh weight and dry weight, sunshade net covers all the utmost point and is significantly higher than wheat straw and covers, and the rate of giving money as a gift also covers higher than wheat straw.This shows that sunshade net covers the accumulation that is more conducive to abundant red sage root seedling dry matter.
The impact of the different seedling raising mannerses of table 9 on abundant red sage root Seedling Biomass
impact on abundant red sage root seedling leaf growth dynamic change
As can be seen from Figure 19, sunshade net covers and grows seedlings, and seedling leaves growth is very fast, covers higher than Wheat Straw always.Before mid-August, two process the equal faster growing of seedling, and after late August, two process merit seedlings and are notch cuttype growth, and sunshade net seedling leaves growth rate covers seedling apparently higher than wheat straw, and this difference may be relevant with the sunshade net power that preserves soil moisture preferably.
(3) water: the sprinkling irrigation of water all being handed over irrigation sprinkler, above sunshade net, by the aperture of sunshade net, slowly falls into water and grows seedlings on furrow;
(4) temperature and relative temperature in net: before emerging, in net, humidity remains on more than 25 ℃, and relative moisture should remain on 75, after 5 days, starts to emerge, and in 9 days, red sage root seedling all sprouts substantially;
(5) taking off net puts away sports equipment: seedling goes out can take off for 5-7 days net puts away sports equipment, and takes off net and puts away sports equipment and should carry out in the afternoon, should not at 3 in afternoon, take off net at 10 in the morning, in case day meal with wine wound;
the difference red sage root seedling dynamic changes of fresh weight under number of days that shades
Shown in Figure 20, three kinds of different number of days that shelter from heat or light represent with R1, R2, R3 respectively, represented respectively 10 days, 30 days and 60 days, three differences shade number of days process fresh weight before mid or late September all in the rapid growth phase, because in the existing obviously decline of left and right temperature on September 7, along with mercury dropped, the photosynthesis of sweat ten certainly will weaken gradually on the one hand; On the other hand, enter autumn, dry weather, air humidity is also more and more less, also will have influence on the maintenance of leaf water, like this from two aspects, from storehouse, photosynthetic product reduces, and from source, water loss is accelerated, so there will be fresh weight to reach after peak value in mid or late September, first have a decline in various degree, then adapting to gradually after ecotope in autumn, fresh weight enters again the slow increase phase.
the difference red sage root seedling dry weight dynamic change under number of days of shading
Shown in Figure 21, three differences shade number of days process thousandweight before mid or late September all in the quick weightening finish phase, but why Rl processes before and after October 19 with respect to processing, dry weight have one so approaching, analyze reason, examine, in conjunction with top fresh weight figure, can find, R2 late September to October early and middle ten days have an obvious fresh weight to decline, the process that dry weight rises on the contrary, then Rl processed at the beginning of mid or late October to 11 month also has a less fresh weight to decline, the process that dry weight rises on the contrary, this explanation is within these two time periods, two processing all show as the now export-oriented growth of seedling and turn to and take nutrient component and stock as main, the nutriment of the lower blade of some old and feeble yellows accelerates to seedling interior shifting, accelerate its aging death, add moisture evaporation, so plant fresh weight sharply declines, on the other hand, although fresh weight declines, but dry matter composition is mostly got up by transhipment storage, so dry weight has increased on the contrary.This,, also from a side illustration, transplants within these two times, because nutriment is all got up by storage greatly, can defeat the resistance to adverse environment condition after transplanting, strengthens the supply to nutrient and energy, and transplanting survival rate is high, returns seedling stage short.
the difference number of days Seedling Height that shades changes
Figure 22 demonstration, R1 processes always with the obvious advantage on plant height, higher than other two processing.R2 is placed in the middle, under R3 occupies, but compares mutually, and R2 and R1 gap are less, have several times also in intersection location.
Shown in Figure 23, R1 processes on stem is thick always with the obvious advantage, higher than other two processing.R2 is placed in the middle, under R3 occupies, but compares mutually, and R2 and Rl gap are less.
the shade dynamic change of red sage root shoot root number under number of days of difference
Shown in Figure 24, the key factor of output basis of formation after root number can be used as and transplants strong sprout, also be one of important references index of commercial seedling cultivation, 12 can find out from the graph, R2 processes the root of hair number of growing seedlings and has a clear superiority in, after mid-September, the quantity of larger 2 grades of roots is maximum always, is the feature of best buy seedling.It is also not poor that R1 processes, but R3 processing is because Shading time is long, is unfavorable for increasing of root number
the difference red sage root seedling fibrous root under number of days that shades is counted dynamic change
Shown in Figure 25, root system is the major organs of plant to moisture and mineral absorption, be again that the various metabolites such as plant are synthetic, assimilation, the organ that transforms, so the growing state of root and mobility directly affect growing state, trophic level and the yield level of plant individual.R2 can find out from lower Figure 14, after mid or late September, take nutrient component and stock in main process of growth turning to, the rapid, high volume emergence period that has a fibrous root, in early or mid October, having approached R1 processes, R2 is before catching up with transplanting in this explanation, has produced the newborn fibrous root that a large amount of vigor are stronger, is applicable to very much transplanting.
difference red sage root seedling index in the strong sprout dynamic change under number of days of shading
Shown in Figure 26, from strong sprout, index broken line comparison diagram, can find out that R2 processes the processing with R1, except having larger decline last November 8, all the time more approaching, while it is not difficult to find after careful observation R2 processing index decreased in strong sprout, but it is root number and a large amount of emergence periods of fibrous root number, moreover strong sprout, index neither be the bigger the better, on comprehensive, compare content, R2 processes apart from beyond more great 2 grades of roots, and newborn vigor fibrous root also has a quick stage of development before transplanting, and strong sprout, index relatively approached Rl always, illustrate that R2 processes with the obvious advantage, be applicable to cultivating strong sprout.
8) field management: should pull out in time the various weeds in field after taking off net, must not use chemical herbicide, simulate wild red sage root seedling breeding base, answer relative moisture higher early stage, soil is slightly dry just should water in time, and the later stage should suitably be controlled water before seedling goes out garden, when running into the superfluous weather of rainfall, should discharge in time the water of simulation in wild red sage root seedling breeding base, generation that should anti-root rot.
Based on the above, in the wild red sage root sapling multiplication growing environment of simulation, the wide 300cm of base furrow grows seedlings, with the long sanitary cleaning bamboo bar of 320cm and the long little timber of 50cm, do and support sunshade net support, sunshade net is 25-30cm overhead, adopts sprinkling irrigation on the net, the base relative moisture that makes to grow seedlings should remain on 55%-60%, within 5-7 days, emerge, after seedling all sprouts in 10 days, remove sunshade net after 4 in the afternoon.
The impact of soil water content on red sage root growth of seedling and biomass, pot experiment adopts vinyon alms bowl (diameter is high 20 cm of 10 cm, basin), every basin soil 210 kg.The red sage root sowing time is on October 10th, 2011, and after emerging, every basin stays 1 strain red sage root seedling.After 30 d of emerging, seedling size is carried out soil moisture processing for 8-10 leaf 1 heart when (November 17).Test arranges 4 soil moistures and processes, be respectively soil moisture content and remain on 15%-20% (W1 of maxmun field capacity (after measured experiment be 2410% with the maxmun field capacity of soil), severe drought), 35%-40% (W2, mild drought), 55%-60% (W3, slight arid), 75%-80% (W4, adequate water supply).Adopt weighing method to carry out artificial moisture control, every afternoon, 18:00 carried out moisturizing, with precision 011 g electronic scale, weighed.4 repetitions are established in test.Soil moisture finishes test after processing 60 d, carries out sampling analysis.
Along with the raising of soil water content, W1-W3 process plant plant height, the number of blade, lateral bud number, leatherleaf is long, leatherleaf top leaflet is long and wide, main root is long, main root is thick and all significantly significantly increases of lateral root number; With W1, process and compare, W3 processes plant These parameters has increased respectively 0.74,1169,10.50,1.00, and 0.80,0.89,0.98,0.66,1.96 times.But adequate water supply (W4 processing) can be crossed and wet obviously suppressed red sage root under ground portion and grow because of soil, processes and compares with W3, W4 processes that main root is long, main root is thick and lateral root number has reduced respectively 35.81%, 42.65%, 56.14%.The above results shows, Water Stress (severe drought and excess moisture) is grown and had larger inhibitory action Salvia miltiorrhiza Growth.
The red sage root is had relatively high expectations to soil water content, and slight arid processing (W3) red sage root seedling leaf is heavy, the heavy and total weight average of root is higher, the raising of each position biomass of the red sage root that Water Stress has been significant limitation.Give money as a gift rate and root/hat of red sage root root is the raising along with soil water content than generally, is the trend significantly reducing, and this shows that soil moisture has obvious regulating and controlling effect with the distribution of under ground portion Assimilate on the ground to the red sage root.
As shown in table 10,11, soil moisture too much (W4) has serious inhibitory action to the growth of red sage root under ground portion and biomass, with W3, process and compare, W4 processing overground part leaflet is heavy has only declined 15.60%, but underground part root division is heavy, root is given money as a gift rate and root/hat is to have declined respectively 65.16% than, 30.88%, 58.44%, this shows that soil moisture too much will cause a red sage root long shoot leaf and not long root.And, in test, also find that adequate water supply processing red sage root root, because of excess moisture, also causes its epiblem cracking and root skin color to be turned white, reduced red rooted salvia exterior quality.
