Described in following embodiment, method is conventional method if no special instructions.
Equipment used in following embodiment, utensil, machinery, fertilizer or agricultural chemicals etc., if no special instructions, all can obtain from commercial channels.
The hybridization paper mulberry used in following embodiment is cultivated by Institute of Botany, Chinese Academy of Sciences's paper mulberry Breeding base, and the public can therefrom obtain in the purchase of section's conception (Beijing) forestry science and technology Co., Ltd.
Embodiment 1. realizes the ecological afforestation on beach saline land and/or seashore beach saline-alkali ground by original soil plantation
(1) selection and the soil of planting nursery stock are selected
1. kind to plant the selection of nursery stock
2012, in oil district, huge port, Tianjin, to hybridization paper mulberry and Chinese wax, the amount of growth after the plantation of saline land has carried out contrast experiment, experiment to be sent out at port in nursery, physical prospecting nursery, the good garden of sunlight one, in the good garden of sunlight five, grandly reach mixing plant, oil multiple experimental point such as company park and lion living area, port has planted hybridization paper mulberry and Chinese wax, from the amount of growth comparison of plant height and thick two aspects of stem.Hybridization paper mulberry and Chinese wax amount of growth contrast the related data that records in table 1.
Table 1
Table 1 result shows, hybridization paper mulberry belongs to the quick growing species of trees, and when liquid manure supply is sufficient, year increment is very large, compares other saline land greening seeds and has higher ageing, can accelerate the greening process in saline land.
2. in soil salt content to the impact analysis of hybridization paper mulberry survival rate
Tangshan Cao Feidian is experimental field the high salt sandy soil formed with making of blowing sand, and obviously, salt content raises from high to low gradually with physical features in salinity gradient distribution.Because the hybridization permeability of paper mulberry root system to soil there are certain requirements, should select that the soil is porous, the plot plantation that physical features is high and dry.According to the salt-tolerant trait of hybridization paper mulberry, set 4 kinds of different salt content soil, adopt ridging original soil cropping pattern, hybridization paper mulberry container seedling is colonizated in sample plot in mid-June, 2010, monthly carries out sampling survey on the spot.
Fig. 1 be in soil salt content to the impact analysis result of hybridization paper mulberry survival rate.Fig. 1 result shows, and when salt content is below 1%, hybridization paper mulberry is all right Cao Feidian surviving experimental field, can be stabilized in more than 95%, and the relatively high salt area of growing way will be got well, and survives rear keep-alive degree high; When salt content higher than between 1% and 1.5% time, after spending the laundering period of two weeks, start to be subject to salt damage impact, occur continuing seedling death phenomenon, survival rate does not ensure; When salt content between 1.5% and 3% or higher than 3% time, sapling survives difficulty, survival rate lower than 20%, under the soil condition of this degree, hybridization paper mulberry cannot realize original soil plantation.
3. soil is selected
When selecting actual cultivation land used in production, Measurement and analysis should be carried out to the salt alkali content in soil in advance, and consider local environment is careful, prevent from, because surrounding enviroment change causes soil salt dynamics, causing damage to production.The specific standards that soil is selected is as follows:
1) should select that the soil is porous, the plot plantation that physical features is high and dry;
2) soil salt content should higher than 1%, to keep the good survival rate of hybridization paper mulberry.
Other are not met to the beach saline land of above-mentioned two standards, by following easy consolidation, can ensure to hybridize the relatively high survival rate of paper mulberry, play the effect reducing greening cost.And meeting the beach saline land of above-mentioned standard by following easy consolidation, the growth result of plant can be better.
(2) consolidation
1. build bar, raised fields, drainage system and land readjustment
The work of consolidation mainly comprises builds bar, raised fields, drainage system and land readjustment, and three work are carried out simultaneously.The soil of bulk trench digging is made certain area independently bar, raised fields separately, has raised physical features, be beneficial to the drip washing of draining and salinity, reduction soil salinity and alkalinity.
For the rectangle soil of long 49m, wide 44m, to facilitate the design that bar, raised fields and drainage system on the rectangle soil that each block is such are described:
As shown in Figure 2, the road of a length and consistent, the wide 4m of described rectangle soil length is set in the rectangle soil of long 49m, wide 44m central authorities, described road by described deduct described path area after rectangle soil be divided into two of area equation blocks of little rectangle soils.
On described two pieces little rectangle soils, open the drain ditch that the broadside in multiple and described little rectangle soil is parallel respectively, ditch top width degree is 3m ± 30 centimetre, trench depth is in 1.5m ± 20 centimetre, and ditch length is consistent with the width in described little rectangle soil, and furrow bank will make the angle to ditch outer incline 45 degree, speed is let out under reducing flowing water, and carry out bank protection process, bat is tight, namely compacting reaches requirement namely to use excavator or spade to be exerted oneself in ditch surface, reduces flowing water to the structural damage of bar field; Multiple drain ditchs on described each little rectangle soil communicate with the described monoblock rectangle soil external world and are interconnected respectively, so that flood season arrives, impeded drainage causes waterlogging.
Described little rectangle soil is divided into bar, the raised fields of polylith independently area equation separately by described multiple drain ditch respectively, and bar, raised fields width are 10m, and length is 20m.
The pattern on bar, whole ground, tableland, artificial changes original topography and geomorphology, planting site is become physical features high and dry; Change the structure of soil, the permeability of the soil of enhancing, while whole ground, form good drainage system; In conjunction with following Rational Irrigation system setting, effectively improve the soil environment in saline land, be conducive to hybridizing the surviving and grow of paper mulberry.
2. apply fertilizer to the subsoil
Another feature in saline land is that in soil, nutrient content is on the low side, and due to saline and alkaline effect, crop also can reduce the absorbing capacity of nutrient.Nutrient deficiency affects crop growing state, reduces output and economic worth.So paper mulberry is planted on saline land as green tree species and economic crops in hybridization, needs the nutritional status improving alkaline land soil, ensures the nutrient supply of sapling, promote tree body growing way.Effective way is application of organic fertilizers material on saline land.
As shown in Figure 3, at each, the ditch of parallel many in excavation and bar on raised fields, the long limit of raised fields for applying fertilizer to the subsoil, furrow width 20 ± 3 centimetres, dark 30 ± 5 centimetres, ditch is apart from 1m, and ditch is interior applies fertilizer by 3,000 thousand grams/acre, enriches NPK composite fertilizer 50,000 grams/acre simultaneously.Return soil and fill out ditch, place 15 days, allow fertilizer become thoroughly decomposed, for subsequent use.Above-mentioned apply fertilizer to the subsoil process described irrigate band laid and fill with once permeable before complete.
3. build water adding system
The design of water adding system will complete before seedling planting, the irrigate band adapted is laid in conjunction with nursery stock band (nursery stock of described preparation field planting is with the ridge be in following step 4) preparing field planting, the drip irrigation system of unified management can significantly reduce the manpower demand of pouring water, and can reduce planting cost in the long run.After irrigate band has been laid, entirely fill with once permeable, drip washing is carried out to salinity in soil, reduce the salt content of soil further, improve the survival rate of nursery stock.
4. ridging
Irrigate band has been laid and has been filled with once permeable rear ridging.Figure 4 shows that each, in raised fields, ridging, arrange the layout in little ditch.
Before plantation hybridization paper mulberry, each, in raised fields, along the direction parallel with bar, the long limit of raised fields, do multiple wide 50 centimetres, the high ridge of high 20 centimetres, namely plants ridge, and the spacing between described high ridge and high ridge is 50 centimetres, and described spacing can be used as aisle.
Because ridge is long time for preventing rainy season, rainwater excessively washes away bar field, cause water and soil loss, destroy bar field structure, ridge can not be designed long, at described each, in raised fields, respectively every 10m design and described bar, the broadside of raised fields parallel breaker, be convenient to disperse draining, described breaker ditch top width 50 centimetres, dark 20 centimetres, ditch length and described bar, the width of raised fields is consistent, furrow bank will make the angle to the inclination outside ditch 45 degree, and carry out bank protection process, namely use excavator or spade that ditch surface is firmly clapped tight, namely compacting reaches requirement.
5. consolidation is on the impact of hybridization paper mulberry growth
In salt content be 1% ~ 1.5% area of Hebei Caofeidian beach saline land on carried out following Comparability test: through the soil of above-mentioned consolidation (after above-mentioned consolidation, the salt content in described saline land is 0.5%) upper and not on the soil of above-mentioned consolidation, after plantation saline land greening seeds (other conditions are the same), the contrast and experiment of tree growth shows: carried out above-mentioned consolidation, and hybridization paper mulberry survival rate is more than 80%; And without above-mentioned consolidation, hybridization paper mulberry survival rate only has less than 0.1%.
The permeability of hybridization paper mulberry root system to soil there are certain requirements, and at hypsography low-lying, plantation hybridization paper mulberry in the region of impeded drainage, because flooded stain easily occurs this type of local content, hybridization paper mulberry root because of being immersed in water, putrefactive phenomenon can occur, so that plant is dead.Experimental field addressing be hypsography low-lying, impeded drainage region in carry out identical implementation process, plant lethality is more than 90%.
(3) hardening
Plant with hybridize paper mulberry be mostly the monthly age that greenhouse by solar heat goes out about plantlet in vitro, directly plantation is in saline land, will certainly delay seedling slow, and slowly, survival rate is low, so suitable hardening is a key measure the good paper mulberry of saline land kind in growth.Sunshade net is adopted to build the hardening canopy of about two meters high, plantlet in vitro is placed in canopy by 0-5 cm distance, sooner or later ventilate in good time, meet fine day intense light irradiation (light intensity is greater than 50,000 luxs), high temperature (temperature is higher than 35 degree) puts down sunshade net cooling, (moisturizing is carried out in placement after 3 ~ 4 days in conjunction with water and fertilizer management depending on concrete condition, rate of water make-up determines according to degree of water shortage), (ventilation time is half an hour first for prolongation ventilation and light application time gradually, later every day increases half an hour, until transplant), generally through the time of 10-15 days, strong sprout can be cultivated, in good time field planting (strong sprout normal growth, seedling without performances such as wilting gets final product field planting).
(4) field planting
The setting date of hybridization paper mulberry is longer, and North China generally all can field planting higher than month when 10 DEG C at the minimum air temperature.Tianjin, the plantation work of Tangshan Area generally completes in 5-9 month.But select in field planting in the first half of the year, nursery stock is through the growth of long period, and the survival rate of surviving the winter can be more guaranteed, and can in output to some extent then.
The hybridization paper mulberry plantation density of juvenile stage (i.e. the strong sprout of about above-mentioned growth 10-15 days) selects 1m × 1m to be advisable, and so does and can make full use of soil under the prerequisite ensureing trunk infusion supply.Selection of time should avoid plant the high noon sunlight is strong, and carry out the dusk being preferably selected in every day.During field planting, first remove the nutritive cube of nursery stock, the complete not loose group of root system that do not fall apart should be ensured as far as possible.The depth of planting is excessively not dark, and the degree of depth does not exceed 20 centimetres, fills with sufficient field planting water in time after field planting.
(5) water and fertilizer management
For detecting the impact of water and fertilizer management on the growth of hybridization paper mulberry, carry out test experience.Setup Experiments four process, each process sets three repetition: ck as control group, do not water and do not apply fertilizer; Process I, watering, fertilizing; Process II, fertilising is not watered; Process III, waters and does not apply fertilizer.
Described process I, the watering and namely irrigate of process III, carry out according to following standard: after seedling planting, need the seedling-slowing stage of about 2 weeks time, period should strengthen water management, and depending on weather condition, the last week waters every other day, and latter one week minimum waters twice water.After Survival rate of nursery stock, water depending on arid situation on the spot, be generally weekly, after entering rainy season, can not water.After nursery stock is very long, before entering the winter, waters freeze-up water in good time, be beneficial to nursery stock and pass the winter safely.To water main points: water it is enough to water at every turn, is sure not to water and partly intercepts water.Describedly water freeze-up glassware for drinking water body in good time and to refer to that at the beginning of late October to 11 month soil carries out encapsulation and freezes water before freeze-up, water too early, not only postpone trees and enter resting stage, but also soil compaction can be made to harden.If pouring too late, easily there is freeze injury.
Described process I, process II fertilising, carry out according to following standard: hybridization paper mulberry generally do not need fertilising, but if as economic tree or greening with nursery stock be guarantee economic flow rate also need rationally to topdress.Can at Survival rate of nursery stock after 2 months, the growth busy season imposes high-nitrogen compound fertilizer once by 0.2kg/ strain, ensures the nutrition supply of tree body abundance.After fall foliage, entirely can apply paddy rice, the stalks such as corn, earth's surface is covered, not only can provide fertilizer deposit for growth in sapling coming year, cold-proof moisturizing can also be played simultaneously and prevent the effect of the accumulation of salt in the surface soil in spring.
Other growing environment of four processed group and condition basically identical, when growing 68 days, from plant height, the number of blade, hat width, diameter, the aspects such as branch number to hybridization paper mulberry growing state added up, statistics is in table 2.Table 2 data acquisition is from Tangshan, and the experiment time is 2010.
Table 2
Table 2 result shows, and the every data statistics in process I is all higher than ck control group, and two group leader's gesture exist very big-difference, proves that liquid manure has obvious impact for the growth of hybridization paper mulberry, and sufficient liquid manure supply obviously can strengthen the growing way of sapling.
In table 2, the every data statistics processed in I group is all higher than process II group generally, proves that the growth of watering for hybridization paper mulberry has obvious impact.Moisture mainly comprises two aspects to the impact that sapling grows: daily management of watering meets the necessary moisture supply of plant strain growth on the one hand, directly facilitates the growth of plant; On the other hand suitable watering serves leaching to the salinity in soil, reduces the salt content of soil, can reduce by 0.3%, the salt stress degree be subject to is reduced, even reach the effect removing salt damage, be conducive to plant strain growth in plant strain growth process.
In table 2, the every data statistics processed in I group is all higher than generally and processes III group, proves that the growth of applying fertilizer for hybridization paper mulberry has obvious impact.In the process of crop-planting, fertilising is a very important job, and this seems more important in the plantation of saline land, and on saline land, plantation is hybridized in the test of paper mulberry, fertilising can not only promote the growth of plant, and also plays a significant role for surviving of nursery stock.
(6) extermination of disease and insect pest, pruning and surviving the winter is managed and protected
Hybridization paper mulberry damage by disease and insect is less, through investigation experiment in recent years, does not find that obvious disease impacts hybridization paper mulberry, and also not easily grows due to the most of insect of special odor hybridizing paper mulberry, reduces trees final-period management cost.In the general time, rare insect pest occurs hybridization paper mulberry, and plant pest concentrates the time of outburst, mainly contains aphid, acarid, can spray Chongmanke missible oil 2000-3000 times of liquid control that percent by volume is 1.8%; The root system of moth class larva to hybridization paper mulberry treelet and sapling can cause comparatively serious harm in addition, and the insecticide that major part control soil on sale on market passes insect is effective to this class pest.Before the plantation of hybridization paper mulberry, the insecticide of pulvis can be admixed with soil, prevent and treat; After plantation, if find insect pest, emulsion insecticide can be applied with water and prevent and treat.
The pruning of hybridization paper mulberry refers to and to control for afforesting the tree-shaped of aspect purposes to hybridization paper mulberry, plays beautify the environment and the effect of beautifulization view to adapt to actual needs.Hybridization paper mulberry is with luxuriant foliage and spreading branches in leafy profusion, side shoot is flourishing, before sapling grows to 80 centimetres, should not operate, ensure the nutritional status of tree body, after sapling grows to 80 centimetres, can dredge out the unnecessary branch of sapling, retain about 5, the top good branch of form, later regular similar pruning is carried out to sapling branch, improve tree soma gradually high, be sure not too early, excessively to prune.Because hybridization paper mulberry side shoot sprouting ability is strong, and growth rapidly, trunk easily bends or tilts, affect the aesthetics of paper mulberry, generally monthly carry out pruning to prune, suggestion is carried out when nursery determining dry treatment, can surely do when tree body grows to about 3m, then transplants 2 years raw nursery stocks after surely dry.
Hybridization paper mulberry can safe overwintering higher than the northern most area of-10 DEG C at the minimum air temperature, if planting site lowest temperature maybe may occur to need to carry out suitable freeze prevention measure to nursery stock lower than the extreme weather of-10 DEG C lower than-10 DEG C.(1) moderate pruning is carried out to nursery stock.(2) weed a garden, in dig ground, to tree root base portion ridging, irrigate anti-freezing water.(3) with the binding such as rice straw, straw rope trunk, play thermal insulation and cold resistance effect, colder area, need to add one deck Polypropylence Sheet outside again.(4) cover ground with agricultural crop straw or with mulch film, plant pit covered, surface temperature (3 ~ 5 degree) can be improved and keep certain humidity (more than 80%) and the accumulation of salt in the surface soil in spring can be prevented.In addition, the mode of improving straw mulching can also grow as fertilizer supply sapling after stalk rots.(5), when the local conditions relatively concentrated some seedling growths allows, when not affecting appreciation effect, available straw mat is built windbreak or is built warm canopy etc. with Polypropylence Sheet.
