Single-seed precision seed and fertilizer co-sowing machine for no-tillage clean areas of cotton
Technical Field
The utility model relates to a cotton fertilizing and seeding technical field especially relates to a cotton no-tillage clean area single seed precision seed manure is with machine of broadcasting.
Background
The cotton is an important economic crop in China, the sustainable development significance of the cotton industry is important, the mechanization of cotton planting is one of important measures for stably developing the cotton production in China, and the cotton planting method is a development direction of future cotton production in China. At present, the cotton planter is still one of the bottlenecks restricting the mechanized development of cotton in China.
The cotton field in Yangtze river basin has two crops in one year more, and after the wheat or rape of the previous crop is harvested, the cotton is planted in a no-tillage way. In the mainstream cotton no-tillage transplanting planting mode in the previous years, because the seedling raising and transplanting are labor-consuming and time-consuming and are not suitable for the development requirement of whole-course mechanization of cotton, the cotton no-tillage mechanical direct seeding mode is gradually popularized and applied. At present, most cotton seeders in Yangtze river basin can meet the requirements of no-tillage, fertilization and precision seeding, but can not treat the residual straws after the previous stubble is harvested. However, residual straws can seriously affect the operation of the seeder, the blockage of the residual straws can easily cause the straw hanging and blocking of the soil-entering parts, the straw blocking can also cause the seed erecting and airing, the seeding operation efficiency and the operation quality can be reduced, the single-seed precision seeding can not realize the full-seedling sowing, and the semi-precision seeding can improve the seeding emergence rate, but increases the seed cost and the manual thinning cost. If the machine is used independently for crushing the residual straws and carrying out rotary tillage, the cost is increased, and the soil tillage layer can be damaged to a certain extent by long-term tillage, so that the development direction of a protective no-tillage technology is not met; the manual removal of the residual straw is not practical due to labor and time waste and low benefit under the current situation that the labor force in rural areas is increasingly tense and the mechanization level is gradually improved.
Xinjiang cotton planter equipment is more advanced, and the seeding technique is more mature, but Xinjiang area territory is vast, and the cotton planter is large-scale machinery mainly, adopts the precision seeding technique on the membrane mostly, generally is a membrane 6 lines of banding mode and a membrane 3 lines mode etc. the cotton field is single-cropping, and is idle in winter, and its planting mode is very different with Yangtze river basin cotton district. In recent years, the air temperature during direct sowing can meet the requirement of seedling emergence, and the direct sowing of cotton is not covered with film in order to reduce the white pollution of the film. Therefore, the cotton planter in Xinjiang is not suitable for cotton areas in Yangtze river drainage basin. The existing no-tillage planter for clean areas is mainly applied to crops such as corn, wheat and peanut, and the existing no-tillage planter for clean areas such as corn and wheat cannot be applied to cotton because the shapes of seeds, the arrangement of plant row spacing, the requirements for straw smashing and covering and the like of different crops are different.
