Description
Technical field
The present invention relates to agriculture field, be specifically related to a kind of method of seedling cultivation of rice.
Background technology
Paddy rice soilless-cultivated seedling has had the history of more than ten years so far, has rock wool, rice husk, glass bead (closed pore) perlite (perforate) seedling-cultivation technique north of China is more representational.Rock wool seedling-cultivation technique, the restriction of cause to reasons such as the harm of human body and pollution on the environments is not further developed, rice husk nursery is due to fermentation rice husk technical sophistication, the problems such as living contaminants causes sprout term disease multiple are not also promoted on a large scale, glass bead (is also perlite, expanded sand) because single perlite nursery has a lot of unfavorable factor, because perlitic permeability conductivity is too strong, very responsive to thermotonus, heat is hotter, meet cool, cause seedling quality poor, do not send out seedling, not packing, indivedual place cannot rice transplanting, seedling death phenomenon often occurs, not accept by common people.
Summary of the invention
For solving the problem, the invention provides a kind of method of seedling cultivation of rice, material is easily got, and granular organic fertilizer, vitamin in a large amount of beneficial microbe produced in batching and batching can meet the demand of growing of rice seedlings.
For achieving the above object, the technical scheme that the present invention takes is:
A method for seedling cultivation of rice, is characterized in that, the method comprises the steps:
S1, get crushed crude pearlite 36-48 weight portion, potato residues 8-10 weight portion, sweet potato vine 18-22 weight portion, phosphate fertilizer 0.5-0.9 part, calcium carbonate fiber 2-3 weight portion, sucrose 1-2 weight portion, potassium dihydrogen phosphate 0.5-1.5 weight portion, urea 0.2-0.4 weight portion, wood chip 15-23 part, shell bits 15-23 part, wheat bran 8-12 part, beancake powder 8-12 part pulverizes respectively, its particle size is at below 5mm, and grain thickness degree is even;
S2, by raw material pulverize after mixing and stirring after add water, make its water content reach 60%-70%, stir 20-40 minute, pH control at 7.0-7.5;
Rear heap fermentation mixed thoroughly by S3, raw material, makes high 1.0-1.2 rice, trapezoidal heap that bottom width 1.2-1.5 rice, length are not limit, thereon with beating some ventilation holes, fermentation 10-12 days, add appropriate water again after fermentation ends, mix thoroughly, regulate water content between 65-73%;
First temperature is risen to 100-105 DEG C under S4, normal pressure, insulation 20-25min; Then temperature is risen to 110-115 DEG C, insulation 60-70min; Again temperature is risen to 120-125 DEG C, be incubated 60-70min when pressure is 0.13-0.14MPa, finally vexedly again put 30-35min, stop heating, allow it naturally cool to less than 28 DEG C;
Ware is cultivated in S5, taking-up, is loaded in culture dish by the medium of step S4 gained, medium is beaten the air-vent at the bottom of multiple straight-through ware, namely inoculates cave;
S6, to sow according to the seeding quantity of dry kind 0.7 kilogram/square metre or bud kind 0.9 kilogram/square metre, evenly after planting, then at the paper of upper covering one deck band air-vent;
S7, band air-vent paper above sprinkle the part by weight modified gypsum of 0.4-0.6, described modified gypsum is formed by lime, flyash and ardealite chemical combination, and then water, irrigation amount is 0.8-1.2 kilogram/square metre, then cover one deck moisturizing mulch film, within after tidy seedlings output 8-12 days, water a Liquid Fertilizer, after 8-12 days, water a Liquid Fertilizer again, each fertilizing amount is 12-20 gram/m, carries out conventional seedbed system and manages.
Wherein, described lime, flyash and ardealite fusion time part by weight be 2-2.5: 15-20: 77.5-83.
Wherein, described moisturizing mulch film adopts non-woven fabrics ventilated membrane.
Wherein, the particle of described flyash is porous type cellular tissue, the particle size range of particle is that the content of 1-100 μm, SiO2 accounts for more than 55% of flyash weight.
Wherein, also Cobastab is added with in described composts or fertilisers of cultivating.
Wherein, the addition of described Cobastab is 20mg/L.
Wherein, nitrogen in described Liquid Fertilizer: phosphorus: potassium weight proportion is 32: 15: 6.5.
The present invention has following beneficial effect:
The operation such as preparation, bottling, autoclaving, inoculation of composts or fertilisers of cultivating of the present invention, all adopts machine operation, saves labor, be conducive to expanding the scale of production, increase yield, reaches high and stable yields to obtain better social benefit simultaneously; Containing abundant organic matter and humus, and containing abundant trace element, possess the whole nutrition needed for rice seedling, matrix unit weight is comparatively light, and without seedling-slowing stage after shoot transplanting equipment, an early stage seedling is fast, disease-free worm's ovum, grass-seed in matrix, seedbed is without the agent of shape seedling, weed killer herbicide, and environmental protection 20-25 days reaches the phase in strong sprout, within 20 days, just can reach machine transplanting of rice rice shoot standard; Adopt air-vent software paper to cover seed rice, not only every cool but also heat insulation, be not only incubated but also moisturizing; Adopt modified gypsum, solid waste phosphogypsum, industrial residue flyash are effectively recycled, lime, flyash is added in ardealite, objectionable impurities such as P2O5 and fluoride chemical combination in ardealite is made to be to useful phosphoric acid salt and silicates material, economize matrix fine sand than single crushed crude pearlite nursery, and 2-3 days can be shifted to an earlier date emerge.
