Abstract
A kind of method of seedling cultivation of rice.The present invention adopts rock wool to do matrix use nutrient solution and grows seedlings.The rice shoot well developed root system of cultivating, the strong shape of stem stalk, rice shoot is not caught an illness, and planting percent can reach more than 95%, slow seedling after rice shoot is inserted, rooting ability is strong, grows soon, and the effective tiller number is many, and comparison is according to volume increase 8%.Water-saving of the present invention, province's fertilizer, seedling cost breeding use floppy disk method at present reduces by 0.23 yuan/square metre.
Description
The invention belongs to a kind of method of seedling cultivation of rice.
At present, the advanced method of domestic seedling cultivation of rice employing is a nutrition soil breeding use floppy disk.In saline and alkaline heavier rice district, use this technology, need the strange land to take a large amount of nutrition soil, increase with the soil amount, and this technology use plastic floppy disk, soil regulating agent, weed killer herbicide and bactericide cause input cost to improve.Technology is than advanced country abroad, and seedling cultivation of rice adopts nutrition soil disinfection hard disk to grow seedlings now, and the nutrition soil that sieves deployed is sterilized with disinfection with high pressure steam, grows seedlings then, and input cost is higher.
The objective of the invention is to work out a kind of good healthy and strong anosis rice seedling of quality that can guarantee to bring out, can reduce the paddy seedling culture method of input cost again.
Principle of the present invention is by adjusting external ecology conditions such as the required nutrition of plant growing, pH value, matrix, make plant growing under optimum condition, thereby promote it to grow, activated the intrinsic disease-resistant gene of plant, produce autoimmunity power, reached the diseases prevention purpose in strong sprout.
Main contents of the present invention are as follows:
1, the bed substrate of growing seedlings adopts the agricultural rock wool of high-quality, or the asepticize matrix of other similar rock wool, and stromal thickness is 1.5-2 centimetre;
2, contained various the concentrating of nutrients ratios are in the nutrient solution:
Nitrogen 250-300PPM, phosphorus 40-60PPM, potassium 200-300PPM, calcium 60-70PPM, magnesium 20-35PPM, iron 1-2PPM, zinc 0.5-1PPM, manganese 0.1-0.5PPM, copper 0.1-0.5PPM;
3, nutrient solution in use, the pH value of allotment is between 4-6.
Major advantage of the present invention is: the rice shoot well developed root system of cultivating, root/shoot ratio are 1, and the stem stalk is strong, and comparison is according to thick 1 millimeter of stem stalk, and hundred strain rice shoot dry weights are the heavy 2-3 gram of contrast, and planting percent reaches more than 95%.Rice shoot is not caught an illness, and root amount comparison is according to many 20%, and root system is energetic, and slow seedling after rice shoot is inserted is grown soon, and the comparison of effective tiller number is according to increasing by 8%.Water-saving of the present invention, province's chemical fertilizer have also been eliminated weeds harm, and seedling cost breeding use floppy disk at present reduces by 0.23 yuan/meter.
Specific embodiments of the invention are described below:
According to the climatic condition on the invention process ground, in time carry out the selection of seedling ground by local seedling cultivation of rice requirements, do work such as seedbed, seed treatment, sowing, seedling management, acclimatization and transplants, wherein different is with prior art:
1, does seedbed-will spread plastic film in the ready-made bed surface, then agricultural rock wool is fetched to immerse in the nutrient solution prepare by every square metre of 1 kilogram of requirement and soak into, take out not flow liquid, it evenly is layered on the mulch film in the seedbed reaches 1.5 cm thicks, not weight is noted on smooth good surface.
2, sufficient nutrient solution waters in sowing-elder generation in medium of seedling bed, is saturation state to rock wool, the poison that will disappear then, urges the seed rice uniform broadcasting of bud on it.Thereupon, cover the following washing river sand of 0.5 cm thick, 10 sieve meshes, to cover seed degree of being completely.Then, cover one deck mulch film again, heat to preserve moisture.
3, the nutrient solution of nutrient solution use-preparation in seedling stage waters when executing, and sows to two leaf stage, and the pH value of nutrient solution is controlled at 4-5, and pH value is controlled at 5-6 behind the two leaf stage.When using, align with a small amount of sulfuric acid at any time.Per 5 days of seedling stage watered and executes one time of nutrition liquid, amount of application with the surface not ponding be advisable.
4, add (NH4) 2SO4:600 gram in the preparation of the nutrient solution-1 ton nutrient solution, the NH4NO3:300 gram, the K2SO4:600 gram, MgSO45H2O:300 gram, Ca(NO3) 2:300 gram, the NH4H2PO4:210 gram, the FeSO47H2O:3 gram, ZnSO4H2O:2 gram, MnSO4H2O:0.5 gram, the CuSO45H2O:0.5 gram, all the other are water.When mix stirring, with Ca(NO3) 2 waters dissolvings separately earlier, treat that other chemical fertilizer stirs evenly dissolving with a large amount of clear water, again with Ca(NO3) 2 the aqueous solution pours into.
Claims (3)
1, a kind of method of seedling cultivation of rice, the bed substrate that it is characterized in that growing seedlings adopts rock wool, contained various thes concentrating of nutrients are in the nutrient solution: nitrogen 250-300PPM, phosphorus 40-60PPM, potassium 200-300PPM, calcium 60-70PPM, magnesium 20-35PPM, iron 1-2PPM, zinc 0.5-1PPM, manganese 0.1-0.5PPM, copper 0.1-0.5PPM.
2, method according to claim 1, the laying depth that it is characterized in that described rock wool is 1.5-2 centimetre.
3, method according to claim 1, the pH value allotment is at 4-6 when it is characterized in that described nutrient solution uses.
