Abstract
The invention relates to a soilless seedling raising method of paddy rice. The traditional soilless raising seedling technology of the paddy rice is immature, which results in phenomena that the quality of seedlings is poor, the seedlings do not grow, roots do not twist, some place is not suitable for transplanting seedlings, and the seedling death usually happens. The invention comprises steps of (1) proportioning substrates: taking and uniformly mixing 1-3 jin of pearlite powder, 1-5 jin of grass carbon, 1-5 jin of fermented plant straw powder, 1-5 jin of fermented livestock feces and 20 grams of slow-release fertilizer; (2) adding a moisture preserving agent and an adhesive into the prepared substrates; (3) sowing seeds; and (4) scattering 0.5 to 0.8 cm of burnt coal ash on paper with air vents in step (3), adjusting pH value of the burnt coal ash to 4.5 to 5.5, watering the coal ash, and covering the coal ash with a moisture preserving land layer, applying a liquid fertilizer to seedlings 8 to 12 days later after the seedling growth, applying the liquid fertilizer to the seedlings again 8 to 12 days later, and carrying out regular seedling management, wherein a non-woven ventilation film is adopted as the moisture preserving land layer , and the fertilizing amount of each time is 15 to 25 g/m<2>. The method in the invention can be used for raising paddy rice seedlings.
Description
technical field:
the present invention relates to a kind of method of paddy rice soilless-cultivated seedling.
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, because the restriction of the reasons such as the harm of human body and pollution on the environment is not further developed, rice husk is grown seedlings due to fermentation rice husk technical sophistication, living contaminants causes the problems such as sprout term disease is multiple also not promoted on a large scale, glass bead (is also perlite, expanded sand) a lot of unfavorable factors because single perlite has been grown seedlings, because of perlitic permeability conductivity too strong, very responsive to thermotonus, heat is hotter, meet cool, cause seedling quality poor, do not send out seedling, packing not, indivedual places cannot rice transplanting, seedling death phenomenon often occurs, by common people, do not accepted.
summary of the invention:
a kind of method that the object of this invention is to provide paddy rice soilless-cultivated seedling, to human body to environment without harm, and it is fast to send out seedling, rice shoot availability is high.
above-mentioned object realizes by following technical scheme:
the method of paddy rice soilless-cultivated seedling, the method comprises the steps:
(1) proportioning matrix: get crushed crude pearlite 1-3 jin, peat composed of rotten mosses 1-5 jin, the plant straw powder 1-5 jin fermenting, the fowl poultry kind ight soil 1-5 jin fermenting, 20 grams of slow-release fertilizers mix;
(2) in the matrix of making, add humectant and adhesive, the ratio of counting is that every 100 jin of matrix add 15 grams of humectant and 20 grams of adhesives, packs Miao Panli into and strike off after evenly mixing, and thickness is 0.5-0.8cm, then water, watering the water yield is 0.8-1.2 kilogram/square metre;
(3) sowing, sows according to the seeding quantity of 0.8 kilogram/square metre of dry kind 0.6 kilogram/square metre or bud kind, evenly after planting, with dull and stereotyped light pressure seed, seed three faces is absorbed in matrix, then at the paper of upper covering one deck band air-vent;
(4) on the paper with air-vent step (3) Suo Shu, sprinkle the coal ash 0.5-0.8cm burning, and regulate the pH value of the coal ash burning between 4.5-5.5, and then water, watering the water yield is 0.8-1.2 kilogram/square metre, then covers one deck moisturizing mulch film, and described moisturizing mulch film adopts nonwoven ventilated membrane, within after tidy seedlings output 8-12 days, water one time Liquid Fertilizer, after 8-12 days, water Liquid Fertilizer one time, each fertilizing amount is 15-25 gram/m again, carries out conventional seedbed system management.
the method of described paddy rice soilless-cultivated seedling, in described slow-release fertilizer, nitrogen content is not less than 9%, and phosphorus content is not less than 4.5%, and potassium content is not less than 1.5%, and zinc content is not less than 0.3%.
beneficial effect:
1, the fowl poultry kind ight soil that adopted the peat composed of rotten mosses in matrix of the present invention, ferments after rear straw, fermentation etc., contain abundant organic matter and humus, and contain abundant trace element, and possessing the required whole nutrition of rice seedling, matrix unit weight is lighter, after shoot transplanting equipment without seedling-slowing stage, an early stage seedling is fast, disease-free worm's ovum, grass-seed in matrix, and seedbed is without the agent of shape seedling, weed killer herbicide, environmental protection 20-25 days reaches the phase in strong sprout, within 20 days, just can reach machine transplanting of rice rice shoot standard.
the present invention adopts air-vent software paper to cover seed rice, not only every cool but also heat insulation, be not only incubated but also moisturizing, and contained several mineral materials in the coal ash of the burning after burning, than the single crushed crude pearlite province's matrix fine sand of growing seedlings, and can shift to an earlier date 2-3 days and emerges.
method of the present invention can reduce throws the fertile number of times watering, and only throws base fertilizer one time, waters Liquid Fertilizer twice, waters water 5-7 time, and every 100 square metres of water savings more than one ton, reduce labor intensity, time and labour saving, and rice shoot availability is up to more than 96%, and mu cost only has 25 yuan of left and right.
the seedling quality that the present invention cultivates is good, and strong stress resistance increases more than 4.5% than the white root of the every young plant body of seedlings and soil, and packing ability increases by 25%, and cost is low, success rate is high, has solved the fetch earth problem of difficulty, diseases prevention difficulty of seedlings and soil.
