In the method, the soil which has low cost and is easy to obtain as the matrix is adopted to cultivate crop seedlings in a factory mode, the method has low production cost and ensures that the transplanted crop seedlings recover in a short period.
Description
Technical field
The invention belongs to the crop-planting technical field, be specifically related to a kind of crop factorial seedling growth transplanting method that utilizes soil to make matrix, be applicable to crop and part forest materials such as cotton, peanut, soybean, rape, sunflower, sesame, tomato, watermelon, cucumber, muskmelon, capsicum, tobacco, corn, millet, Chinese sorghum, paddy rice, onion, garlic.
Background technology
The crop factorial seedling growth is normally made matrix with non-earth materials such as vermiculite, the peat composed of rotten mosses, sandy soil, coconut palm powder, peanut shell, the straw that becomes thoroughly decomposed, perlites, these materials because of or have good permeability, a moisture-keeping, fertilizer-keeping, or have light weight eutrophy, lifting easily, hinder advantages such as root is few and be widely used in the crop factorial seedling growth, but have more volume disaster transportation, non-renewable, price is high, the alms bowl body easily looses, transplants shortcomings such as the back seedling-slowing stage is long behind the lifting.
Make matrix with soil, raw material is easy to get, and need not transport for long-distance, and cost is extremely low, and alms bowl body and root system strong adhesion behind the lifting, but owing to matter heavy and reasons such as the alms bowl body easily looses, root system frangibility, and can't be used as matrix by factorial seedling growth.
In the sixties in last century, because the needs of multiple cropping development, the cotton grower makes nutritive cube with soil and is applied to raising seedling of cotton.Because the nutrition-pot body is bigger, labour intensity is very big in production links such as system alms bowl, an alms bowl, transportation, can't be adopted by factorial seedling growth.
Chinese patent 02110038.1 discloses a kind of Cultivation of Cotton Seedlings Without Soil and pot-free transplanting method thereof, this method is evenly laid on the seedbed or on the seedling-cultivating tray in the greenhouse shed with sand or coconut palm powder or vermiculite or its and is combined into the hypothallus of matrix, cotton seed is sowed on seedling-cultivating tray, after planting cover with matrix, and it is moistening to medium matrix to spray water, cover film afterwards, regular spray nutritious liquor in the nursery stage, after coming into leaves, takes off cotton seedling the film hardening, lifting, be stained with root with promoting agent behind the lifting, to guarantee that cotton seedling still has very high survival rate after certain storage and haulage time, behind the no potted-seedling transplanting that above-mentioned steps is cultivated, should note watering immediately.This method is naked transplanting of no alms bowl, and labour intensity is low, but still has a little defectives: as need in time water after planting, and higher to cotton seedling quality requirement, to be prone to seedling-slowing stage long etc.
Summary of the invention
The present invention is intended to overcome existing factorial seedling growth and produces the restriction that mesostroma must be purchased, a kind of crop batch production soil matrix method for culturing and transplanting seedlings is provided, this method is matrix with soil, soil abundance, cheap and easy to get, effectively alleviated the matrix resource of growing tension on the one hand, also find a kind of good solution on the other hand, be particularly useful for cotton for overcoming seedling-slowing stage behind the batch production shoot transplanting equipment, peanut, soybean, rape, sunflower, sesame, tomato, watermelon, cucumber, muskmelon, capsicum, tobacco, corn, millet, Chinese sorghum, paddy rice, onion, various crop such as garlic.
For achieving the above object, the present invention adopts following technical scheme:
A kind of crop batch production soil matrix method for culturing and transplanting seedlings, it is in the hole, seedling-cultivating tray cave of crop (purpose crop just) planting seed after the spreading soil matrix, or directly the crop seed sowing is covered with soil matrix in the hole, cave again; Put into plastic sheeting for farm use shed or greenhouse then, keep soil matrix humidity 50%-70%(can be by watering or spray nutritious liquor keeps the corresponding humidity of soil, be beneficial to seed growth, water can adopt from the seedling-cultivating tray bottom floating, overflow form such as water, also can adopt from seedling-cultivating tray top spraying or overflow form such as water), crop emerges after take off film or open the canopy hardening, can play transplantation of seedlings.
The inventive method goes for all crops that can adopt seed seedling-raising and part forest material etc.Below only enumerate some common crops, but the described crop of the inventive method is not limited thereto.Common crop is as cotton, peanut, soybean, rape, sunflower, sesame, tomato, watermelon, cucumber, muskmelon, capsicum, tobacco, corn, millet, Chinese sorghum, garlic, onion, paddy rice and wheat etc.
Preferably, mix the soil binder that adds soil weight 0.001-10% in the soil, described soil binder is preferably one or more in sodium cellulosate, cellulose, sodium carboxymethylcellulose pyce, methylcellulose and the polyvinyl lactam etc.
In addition,, strengthen crop root intensity, can between nursery stage, spray the crop rooting promoter for increasing crop root quantity.Crop rooting promoter commonly used can be in heteroauxin, heteroauxin sodium, methyl, Nafusaku, indolebutyric acid, indolebutyric acid sodium, indolebutyric acid methyl esters and 2, the 4-D butyl ester etc. one or more.When spraying, be that the aqueous solution of 0.0001-1000mg/Kg is advisable above-claimed cpd is made into mass percentage concentration.
Preferably, a kind of crop batch production soil matrix method for culturing and transplanting seedlings, one or both in crop and the above a kind of seed of seed in the purpose crop are sowed in the same hole of seedling-cultivating tray mutually for they, (by watering or spray nutritious liquor makes the corresponding humidity of soil conservation, can regularly spray rooting promoter in the nursery stage), when hardening is formed the alms bowl body that is difficult for scattering or does not loose to crop root with soil matrix (when the crop root of hair trips out to the alms bowl physical efficiency is complete), play transplantation of seedlings.
So-called purpose crop is meant the crop to be transplanted (being retained) of growing seedlings; And mutually as crop be meant utilize its root system purpose crop alms bowl body is reinforced or weaken the purpose crop root from toxic action, with so that the better crop of purpose plant growth, be to sow, after playing transplantation of seedlings, be removed or the repressed crop that grows with the purpose crop.
When crop root is formed the alms bowl body that does not loose with matrix, preferably, can remove crop (mode that employing sprays will be killed as crop mutually) mutually with selective herbicide, play transplantation of seedlings then.The present invention uses foliar herbicide behind the selectivity seedling.
With the selectivity foliar herbicide remove crop seedling mutually operation can for: when transplanting preceding 1～10 day, spray one time the selectivity foliar herbicide, perhaps when the crop seedling surpasses purpose crop seedling plant height mutually, spray once, when transplanting preceding 1～10 day, spray one time the selectivity foliar herbicide again.Can be when playing transplantation of seedlings with purpose crop seedling and the remaining seedling of crop mutually lifting and transplanting together, the crop seedling is slowly withered mutually afterwards dies, thereby only survives purpose crop seedling.The effect of selective herbicide is that the crop mutually and the purpose crop seedling of will plant together separate, and promptly kills crop seedling mutually, keeps purpose crop seedling.Behind the commercially available selectivity seedling commonly used there be foliar herbicide: efficient fluazifop, the spirit of pyrrole fluorine chlorine standing grain, efficient haloxyfop-methyl spirit, Quizalotop-ethyl, fenoxaprop, sethoxydim (sethoxydim), clethodim, pyrithiobac-sodium, dicamba, tribenuron-methyl, Bentazon, isoproturon, fomesafen and fluorine grass are fixed etc.
Compare beneficial effect of the present invention with prior art:
Traditional factorial seedling-culturing method, if adopting soil to make matrix then can't solve the alms bowl body, seedling medium on links such as transportation lifting, plays technical problems such as alms bowl, alms bowl easily loose, root is easily broken, thereby adopt materials such as vermiculite, the peat composed of rotten mosses, sandy soil, coconut palm powder, peanut shell, the straw that becomes thoroughly decomposed, perlite usually, but these materials have more volume disaster transportation, non-renewable, price is high, cohesive force is relatively poor between self particle, often need form more open little alms bowl body by the connection of root system.And little alms bowl body regular meeting is because of the vibrations spallation in the lifting transportation, thereby the naked transplanting of having to, and causes seedling-slowing stage prolongation etc. behind the crop shoot transplanting equipment, makes the factorial seedling growth cost up, and production development is very limited.
The inventive method is seedling medium with soil, overcome factorial seedling growth and produced defectives such as mesostroma must be purchased, matrix resource growing tension, opened up the substrate range of factorial seedling growth, make that factorial seedling growth matrix is extensively changed, generalization, its resource has obtained greatly abundant, factorial seedling growth matrix no longer is production constraint, and the application of industrial breeding technique will further be enlarged.Simultaneously, transplant because the present invention is little alms bowl soil, the rice shoot seedling-slowing stage is short after planting, survival rate is high, so production-increasing function is obvious.Beneficial effect of the present invention is as follows:
1, compare with nutritive cube:
(1) be fit to factorial seedling growth: feeding block seedlings raising is because system alms bowl, sowing recruitment are more, and the alms bowl body is bigger, and problems such as the alms bowl body easily looses, transportation difficulty concentrate that the scale breeding cost is higher, transportation difficulty etc., extremely difficultly adapts to batch production and concentrates and grows seedlings.Compare with the present invention, strictness does not belong to same technical field in fact.Because the present invention need not make alms bowl, only be substituting of cave dish soilless-cultivated seedling technology mesostroma, but owing to can form a little alms bowl behind the lifting of the present invention, for the present invention there being a comprehensively examination assessment, this paper compare explanation to it.
(2) need not to make alms bowl, pendulum alms bowl, an alms bowl etc., be fit to the mechanization sowing: the present invention only is substituting of cave dish soilless-cultivated seedling technology mesostroma, need not make alms bowl, puts alms bowl, play alms bowl etc., and sowing can be carried out mechanization.
(3) the fortune seedling, to plant seedling labour intensity little, easily quick, is fit to mechanization transplanting: the present invention is because the alms bowl body that forms behind the lifting is minimum, its weight only be one of percentage of conventional nutritive cube less than, alms bowl body volume is also minimum, only be conventional nutritive cube 1/30 less than.Therefore, convenient transportation, labour intensity is little, and suitable for mechanization is transplanted.
(4) root system and matrix strong adhesion, alms bowl body are difficult for loosing: the present invention is owing to there is the effect of making crop root and rooting promoter mutually, and root system is more in little alms bowl body, root density is bigger, thereby the little alms bowl body breaking resistance that forms is big, and the alms bowl body is difficult for loosing.
2, with the soilless substrate ratio:
(1) matrix need not to buy, can local localization: though the present invention is a kind of factorial seedling-culturing method, because of matrix is soil, various places all can be gathered voluntarily, thereby need not to buy and long-distance transportation, will make that the factorial seedling growth range of application is more extensive, seedling cost is more cheap.
(2) aboundresources: the soilless substrate that the present invention must buy factorial seedling growth has in the past become soil, and all there is rich in natural resources various places, and the factorial seedling growth of making over adopts non-renewable resources to become renewable and ecological, environmental protective more.
(3) but root system and matrix strong adhesion carrying substrates form little alms bowl body, it is short to plant the back seedling-slowing stage: the present invention is owing to there is the effect of making crop root and rooting promoter mutually, and extremely Duo root system can play good reinforcement effect to little alms bowl body of formation.Therefore, easily form fabulous little alms bowl body, can be rice shoot temporary transient nutrient and water supply is provided, also can make crop root be subjected to certain protection simultaneously.Thereby seedling-slowing stage is short after planting.
