Description
One, technical field
Mulch film precision sowing auxiliary instrument of cotton of the present invention relates to a cover cotton precision seeding machine and an operating technology, is used for the sowing and the epiphragma of bollworm-resistance hybrid cotton mulch film Precision Seeding thin planting technology, belongs to Crop Planting Management Agriculture Expert technology aid.
Two, background technology
In recent years, two big factors seriously restrict the Growth of Jiangsu Cotton production development, and the one, the rural laborer shifts, and Cotton Production labour reduces, and quality of the workforce obviously reduces, and the cotton culture technology must be simplified; The 2nd, the bollworm-resistance hybrid cotton of high yield and high quality strong stress resistance is promoted rapidly; but because breeding cost height; only on the seedling raising and transplanting cotton, use at present; conventional transplanting cotton is grown seedlings and transplants that process management is numerous, recruitment is many, labour intensity is big; incompatibility is planted cotton needs of scale production; must simplify and reform, the light-duty simplification new cultivation technology of research adaptation bollworm-resistance hybrid cotton new varieties is extremely urgent.The live cotton precocity of mulch film, high yield, high-quality, worker employed in a plant nursery are few, be suitable for the scale plantation, but production upper seeding wheel amount is big, can not adapt to the needs that the bollworm-resistance hybrid cotton new varieties are used, film cotton must reduce sowing quantity significantly, to adapt to the requirement that the bollworm-resistance hybrid cotton new varieties are used.Under existing situation, the advantage that realizes saving of labor, mechanization and make full use of bollworm-resistance hybrid cotton high yield and high quality strong stress resistance is the developing direction of cotton culture technology, our unit develops formation " bollworm-resistance hybrid cotton mulch film Precision Seeding thin planting high-yield high-efficiency cultivation technology " on the film cotton basis, this technology is taked the mulch film Precision Seeding, rational close planting, reduced the land for growing field crops sowing quantity significantly, satisfied bollworm-resistance hybrid cotton new varieties application requirements on the live cotton of mulch film, created conditions for realizing the cotton large-scale planting; New technologies such as the integrated high-quality of this technology is sowed, keep a full stand of seedings seedling stage, vegetative shoot utilization rationally in conjunction with the reasonable adjustment of changing accent, fertilizer practice, are cultivated high-quality colony, realize super high-yielding.This technology combines stable high yield and the resistance and the quality heterosis of bollworm-resistance hybrid cotton, the saving of labor of the live cotton of mulch film, the suitable for mechanization production advantage, have high yield, high-quality, degeneration-resistant, saving of labor and be convenient to the characteristics of mechanized operation, be suitable for a cotton and cover cotton field plantation of spring.Efficient in order to bring into play the volume increase of this technology saving of labor abridged edition, we develop the Aided Machine of suitable bollworm-resistance hybrid cotton mulch film Precision Seeding thin planting technology agriculture requirement.
Three, summary of the invention
Technical problem
" bollworm-resistance hybrid cotton mulch film Precision Seeding thin planting high-yield high-efficiency cultivation technology " requires to be mainly to seeding quality: 1. sowing quantity reduces as far as possible, and general cotton field should be controlled at below the 500g/ mu, and the cotton field, saline land is controlled at 750g once, and the seed costs peasant can accept; 2. want one to broadcast Qi Miao, can not reseed; 3. prevent dead seedling: prevent to scald dead seedling, prevent the dead seedling of seedling diseases, reduce the dead seedling of insect pest.Requirement to sowing is: depth unanimity, and it is neat to emerge, and it is timely to put seedling, and native face is left a blank, the back spray medicine in time that helps emerging, preventing disease pest control.The manual operation uniformity is poor, is difficult to reach this technology sowing agriculture requirement.The design assistive device is to satisfy this technology sowing agriculture requirement, reduces labor intensity the needs of raising the efficiency.
