Description
Technical field
The invention belongs to seed coating technology field, relate to a kind of seed-grain being coated with pelletized matrix, and the preparation method of described pelletized seed-grain.Pelletized seed-grain prepared by the present invention can be sowed under the state of water suction vernalization, improves the drought-resistant ability of seed-grain.
Background technology
Millet (
setariaitalica(L.) P.Beauv) originate from China, belong to grass family broomcorn millet race setaria, the cultivation history of existing more than 8700.Millet drought resisting resistance to lean, Water use efficency is high, wide adaptability, is the important regional characteristic cereal crops in arid and semi-arid lands, to the industry restructuring of arid and semi-arid lands of China and grain security significant.Millet is nutritious, and not only containing the nutrient that multiple human body needs, and between various nutrient, balanced proportion, particularly crude fiber content are minimum in several staple food crop, and therefore nutritive value is higher.Along with the rise of coarse cereals heat in recent years, millet market prospects are had an optimistic view of, and price is day by day soaring, become the Important Economic source crop of arid area increasing peasant income.
Millet thousand kernel weight only about 2.0 ~ 3.0g, every kilogram of seed reaches 30 ~ 350,000, and suitable density of reserved seedlings is 37.5 ~ 750,000 strains/hm
2, namely sowing quantity is only 2.5 ~ 4.5kg/hm
2.Fritter plantation millet generally uses animal-drawn seeding plough, man-driven seeder, with drilling, broadcasts sowing and sows with the mode of bunch planting.The sowing of larger area plot is in recent years for adapting to agricultural modernization, Mechanization Development demand, adopt fluted-roller feed mechanism, cell-seed distributor, reciprocating sowing apparatus and multi-functional formula seeding unit to carry out half essence amount and precision drilling more, and achieve certain effect.
Due to paddy seed footpath little (1 ~ 3mm), kernel weight is comparatively light, and small and weak paddy seedling needs to play colony and pushes up native power guarantee full stand, and seeding quantity is too small is unfavorable for full stand, therefore, during millet planting often to strengthen seeding quantity to reach the object of saving seedling, constantly ridge from damage.It is large that this cropping pattern causes millet Seedling density, must implement thinning, take a lot of work and mistake.Meanwhile, large seeding quantity certainly will cause nutrient competition fierceness in seedling stage, fights for nutrition and produces thin and weak seedling, high pin seedling, affect later stage plant strain growth between individual plants.In addition, because millet Seed shape is irregular, in addition millet particle diameter and thousand quality less, during mechanical planting, mobile performance difference is comparatively large, is difficult to the agriculture requirement realizing precise sowing.These outstanding problems become the subject matter of restriction millet development, seriously constrain the industrialized development level of millet.
The common method solving problems is that seed-grain is pelletized.Seed-pelleting (seedpelleting) process technology uses special process; by medicament, fertilizer, growth regulator be evenly wrapped in the surface of the seed to the auxiliary adding material that seed has no side effect, form the processing technology of smooth surface seed with definite shape, intensity.After Pelleting, seed not only effectively can realize broadcasting front plant protection, band fertile band medicine is gone to the field, reach the object of strong sprout of keeping a full stand of seedings, regulating crop growth, also for mechanization precise sowing creates advantage, thus the object economizing on kind, improve output, cost-saving synergistic is in a large number reached.
Mainly there is following several respects problem in the pelletized technology of existing seed-grain.1, matrix formulations is simple, drought resisting, diseases prevention, insect protected, nutriment comprehensive reasonable is not used; 2, because paddy seed footpath is little, lightweight, can only be made into the pelletized seed-grain of boundling, boundling pill seed-grain can cause the plant in same pill, in seedling stage, nutrition contention between individuality occurs, and certainly will affect the late growing stage of plant; 3, the seed-grain size after Pelleting is uneven, and mobile performance difference is comparatively large, is difficult to the requirement meeting precise sowing.
What is more important, millet is multiple is implanted in arid, Semi-arid Mountain Area or hilly country, these regional spring arid, and wind is rainy few, and soil moisture evaporation discharge is large, and topsoil dehydration is very fast, does not have the local evaporation of soil water situation of irrigation conditions severeer.But the pelletized technology of existing seed-grain has only been focused on Pelleting kind and absorbed water from soil, require higher to soil moisture, do not possessed the effect improving emergence rate under arid and semiarid condition.In addition, Pelleting kind after planting absorbs water and also needs the regular hour from soil, during this period of time easily suffers coercing of external environment, and as strong wind in spring, topsoil dehydration is very fast, the rate variance that easily causes emerging, the phenomenon such as uneven of emerging.
Usually, when running into soil moisture content deficiency, need first to carry out vernalization to seed-grain, then sow.The pelletized seed-grain carrying out vernalization sowing emphasizes the unification of rate of cleavage and compression strength, and making every effort to realization can absorb water under comparatively low moisture condition, and itself also will have certain compression strength.And with Pelleting kind rapid disruption after absorbing water prepared by current pelletized technology, can not absorb water vernalization prior to seeding, mechanical planting difficult quality controls, and significantly limit artificial, the mechanical planting of Pelleting kind.
Therefore; research one can absorb water prior to seeding; and do not open loose after water suction; there is good expansibility; the pelletized seed-grain of Mechanization sowing still can be adopted after seed-grain can be made to sprout in pelleting agent; to ensure that seed-grain can emerge smoothly in arid, semiarid zone, well grow, the industrialized development for millet is of great practical significance.

Application examples 1: millet Pelleting kind and naked seed laboratory comparative trial
For checking dressing Pelleting kind effect, in laboratory, have seed rate, single seed rate, the cracking severity of different embodiment Pelleting kind are investigated, and carry out germination test in laboratory.Germinate and use soil to take from field, relative water content 60%, sowing depth 1cm, in each germination box, sow 100.Laboratory temperature 25 DEG C, humidity 60%.Test in triplicate, is averaged, the results detailed in Table 1 ~ table 3.
As shown in table 1 ~ 3, in 3 tests, millet Pelleting kind has the investigation of seed rate to be 100%; Single seed rate investigation is respectively 98%, 100% and 99%; Cracking severity is respectively 79%, 80% and 83%.
In 3 tests, Pelleting kind germination rate is respectively 94%, 94% and 96%, naked seed is then respectively 95%, 94% and 97%, Pelleting kind germination rate is slightly lower than naked seed, but difference is little, show that naked seed does not significantly reduce at its germination rate after Pelleting coating process, to later stage germination, emerge and can not have a negative impact.
Pelleting kind 3 days germination vigoies are respectively 25%, 30%, 27%, and corresponding naked seed is respectively 87%, 84%, 88%; Pelleting kind number of days of emerging needs 5 days, and naked seed only needs 3 days.Tracing it to its cause, is that therefore germination and growth is grown slightly slow, and its 3 days germination vigor ratios are about about 30%, and naked seed 3 days germination vigoies can reach more than 85% owing to needing when Pelleting kind is sprouted to break through coatings.Final Pelleting kind emergence rate is respectively 94%, 94%, 96%, and corresponding naked seed is respectively 95%, 94%, 97%, and difference is little between the two.
In sum, germination test shows that Pelleting kind has seed rate to reach 100%, and single seed rate can reach more than 98%.In this test, Pelleting kind cleavage rate is respectively 79%, 80% and 83%, has notable difference with the cleavage rate of other existing Pelleting kinds, illustrates that Pelleting matrix component proportioning of the present invention can obviously affect Pelleting kind cracking severity and germination vigor.In addition, the rate of cleavage of Pelleting kind is also relatively slow, do not fall apart after this feature and its vernalization, there is good elasticity and expansibility closely related.More than test shows, the present invention makes Pelleting kind does not affect percentage of seedgermination, emergence rate, and Pelleting degree is good, is convenient to vernalization Mechanization sowing.
Application examples 2: non-irrigated canopy Pelleting kind vernalization sowing comparative trial
Following method is adopted to carry out vernalization to Pelleting kind:
1), by seeding quantity take Pelleting kind, spread into one deck out and be laid in Flat bottom container, in container, add running water, the depth of water is 1/2 ~ 3/4 of Pelleting kind diameter, 25 ~ 28 DEG C of indoor placements 18 ~ 28 hours, avoids stirring.
2), get a little Pelleting soaked, peel off dressing and check germination.Show money or valuables one carries unintentionally to more than 95% Pelleting kind, then can carry out next step operation.
3), remove excessive moisture in container, dry 2 ~ 4 hours, a little talcum powder is sprinkling upon Pelleting kind surface, prevents adhesion, can sow.
The vernalization of Pelleting kind, Pelleting kind and naked seed insemination and emergence comparative trial is carried out in non-irrigated canopy.The drought canopy soil texture is loam, relative water content 50 ~ 60%, environmental temperature 18 ~ 26 DEG C, plot area 8m
2(4m × 2m), line-spacing 1 chi, sowing depth 2cm, broadcasts the suppression of rear equal conditions, and process and contrast are sowed in each community simultaneously, and three tests repeat.
From non-irrigated canopy comparative trial, more late than naked seed 3 ~ 4 days of the number of days although the non-vernalization of millet Pelleting kind is emerged, its emergence rate is higher than naked seed by 6 ~ 8%, there is certain advantage.And number of days of emerging after the vernalization of Pelleting kind only needs 9 days, almost close to naked seed speed of emergence, emergence rate more reaches 96%, has clear superiority compared with naked seed emergence rate 85%.Although naked seed number of days of emerging is 8 days in test, emergence rate 85%, but often there is field seeding site preparation quality situation not up to standard in actual production, if when naked seed is by half Precision Seeding or the sowing of Precision Seeding amount, may to push up native power little due to colony, emergence rate can decline further, and the advantage of Pelleting kind can manifest further.Meanwhile, if soil moisture content is after planting because environmental change loss is comparatively large, then the advantage of vernalization Pelleting kind can be more obvious.
In addition, because pelleted seed skin (also can add hormone containing a certain amount of microelement fertilizer, root-growing agent, the materials such as drought resisting) and insecticide and bactericide, Pelleting kind is due to Gonna breakthrough coatings, therefore before three leaf one heart stages, growing way is slower, but plant height is basic fair with naked seed during three one heart stages of leaf, thin and weak seedling is less, generally healthy and strong than naked seed seedling, and growing way is very fast before naked seed three leaf one heart stage, but thin and weak seedling and high pin seedling more, its growing way three leaves wholeheartedly after date just there is no advantage, if infect damage by disease and insect, its seedling growth can be had a strong impact on, then there is not problems in Pelleting kind.
The mu sowing quantity about 0.25 ~ 0.5kg of Pelleting kind, naked seed is 1.0 ~ 1.5kg about, and naked seed thinning generally about needs casual labourer 4 ~ 5, and Pelleting kind only needs 1 ~ 2, serves the effect of cost-saving synergistic.
The pelletized seed-grain using the present invention to prepare improves the problems such as naked seed particle diameter is little, lightweight, out-of-shape; its mobile performance is greatly improved; substantially the agriculture requirement of essence amount, semi-accuracy seeding can be met; can effectively preventing damage by disease and insect; promote growing of millet; the pelletized seed-grain of what is more important can be sowed under the state of water suction vernalization, improves the drought-resistant ability of seed-grain, produces significant for China Arid&semi-arid area millet.
