Description

A kind of method that postpones the coating material of seed sprouting and prepare capsuled seed
The present invention relates to a kind of technology that postpones seed sprouting.Particularly relate to a kind of method that postpones the seed pelleting material of seed sprouting and prepare capsuled seed.
China is populous, a few country of soil owning amount per capita.In order to solve the problem of food and clothing of 1,000,000,000 populations, must improve the availability in soil.Therefore, taking 1 year two batches or many batches of shift of crops in area with good conditionsi, is the basic tillage system of China.In certain areas,, cause the yield and quality of rotation crop to descend owing to shortage of heat breeding time.Adopt and interplant the breeding time that then can prolong crop effectively, the yield and quality that improves crop.But traditional-handwork interplanting work efficiency is very low, and conventional mechanization interplanting operation is difficult to realize.So, adopt the technology of retarded germination can realize conventional mechanical interplanting operation, two batches of crops that solve crop rotation are fought for the contradiction in farming season.
The wheat that generally adopts with the suburb of Beijing and the tillage method of interplanting corn are example, gather in the time of next year wheat cultivation from wheat and have only 90～100 days.This just makes shortage of heat breeding time of conventional flat planting summer corn, yield and quality descend.If adopt conventional interplanting technology, the result both can damage the wheat of having planted, cause production loss, and work efficiency is also very low simultaneously.Adopting the retarded germination technology then corn can be advanceed to the wheat growth that is easy to mechanized sowed in the phase.Like this, both can avoid injuring the wheat of having planted, and can utilize interplanting to fight for farming season again, satisfy the needs of the breeding time of corn, reach the purpose of dual volume increase.Also removed the operation that conventional summer corn is ploughed, harrows, broadcast simultaneously from.In addition, adopt the retarded germination technology also fundamentally to prevent the generation of steamed dumplings straw phenomenons, help protection surrounding environment.
