A paddy rice sprout cultivation method comprises the following steps of selecting seeds and sub-packaging seeds; and further comprises the following steps of disinfecting in hot water, cooling, soaking seeds at a constant temperature, accelerating germination at a constant temperature, dehydrating, precisely seeding, germinating in a conservatory, and cultivating rice shoots in a greenhouse. The paddy rice sprout cultivation method is characterized by reducing manpower cost, reducing labor intensity, and increasing work efficiency; the method is economical and practical, safe and environment-friendly as well.
Description
Technical field
The present invention relates to a kind of paddy rice nursery method.
Background technology
At present, paddy rice nursery method mostly is seed selection, pharmacy disinfection, soaks seed, is filtered dry, vernalization, artificial seeding, Small plastic shed nursery.Pharmacy disinfection easily makes paddy rice germination rate reduce; Be filtered dry vernalization easily to occur to burn kind or rotten kind of phenomenon; Artificial seeding is difficult to the requirement reaching evenly sowing; Small plastic shed nursery easily occurs to burn seedling phenomenon.
Summary of the invention
Its object of the present invention is just to provide a kind of paddy rice nursery method, has the advantages that to reduce cost of labor, reduce labour intensity, increase work efficiency, both economical and practical, safety and environmental protection again.
Realize above-mentioned purpose and the technical scheme taked, comprise
1) choose seeds;
2) packing;
Also comprise
3) hot water disinfection, cooling;
4) constant temperature seed soaking, constant temperature vernalization, dehydration;
5) precision drilling;
6) greenhouse germinates;
7) raise seedling in greenhouse.
Compared with prior art the present invention has the following advantages.
1) all adopt mechanized operation from seed selection to raise seedling in greenhouse, reduce cost of labor, reduce labour intensity, increase work efficiency, omnidistance seedling time early rice 23-25 days, 5-7 days is done sth. in advance in more conventional seedling; Semilate rice 20-22 days, 3-5 days is done sth. in advance in more conventional seedling; Late rice 18-20 days, 2-3 days is done sth. in advance in more conventional seedling.
2) mode adopting hot and cold water to replace in disinfecting process carries out the sterilization of seed, both economical and practical, safety and environmental protection again.And conventional seedling generally adopts pharmacy disinfection, both affected germination rate, again certain pollution was caused to environment.
3) because presoaking and germinating all carries out in thermostatted water, sprout neat, even, " burn and plant " of causing because local temperature is uneven or " rotten kind " phenomenon in conventional seedling can not occur.
4) in germination process, adopt greenhouse Germination methods, improve speed of emergence and quality by Steam Heating, air pump oxygen supply, in more conventional seedling, conventional normal temperature germinates and has quick, even, neat advantage.
5) more more sowing quantity is saved with conventional seedbed system, more saving water resource.
