Cotton film-free drip irrigation cultivation method

Abstract

The invention discloses a cotton film-free drip irrigation cultivation method, which comprises the steps of sowing and field management, and the field management comprises the steps of irrigation, fertilization, chemical regulation and control, intertillage weeding, disease and pest control and topping; and harvesting. Compared with the prior art, the cotton film-free drip irrigation cultivation method has the advantages that residue and pollution of the mulching film in soil are reduced, physical and chemical properties of the soil are improved, sowing quality and field emergence rate are increased, root systems of crops are promoted to prick downwards and grow stably, early senility in the later period is prevented, the quality of agricultural products is improved, and meanwhile, the agricultural production environment is improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cotton filmless drip irrigation cultivation method. Background technique [0002] Since the promotion of plastic film cotton planting technology in Xinjiang in the 1980s, the problem of plastic film residual pollution has been very serious. The cost of manual removal of mulch film in cotton fields in southern Xinjiang is getting higher and higher. The promotion of under-mulch drip irrigation technology has led to a decrease in the removal rate of mulch film. The cotton field is not removed at all in the production and operation of the winning style, and the residual rate of the plastic film is as high as 100%. The annual average residual rate of the plastic film in Xinjiang is 24.4%. The pollution of the soil environment has become one of the most serious areas in the country. [0003] During the recycling process of film-covered cotton, due to the limitations of recy...

Problems solved by technology

The cost of manual removal of mulch film in cotton fields in southern Xinjiang is getting higher and higher. The promotion of under-mulch drip irrigation technology has led to a decrease in the removal rate of mulch film. The production and management of the cotton field is not to remove the film at all, and the residual rate of the plastic film is as high as 100%. The annual average residual rate of the plastic film in Xinjiang is 24.4%. The pollution of the soil environment has become one of the most serious areas in the country.

[0003] During the recycling process of film-covered cotton, due to the limitations of recycling residual film, and the incomplete treatment and recovery of residual film, the method is not appropriate, and some of the cleaned-up residual film is discarded in fields, fields, canals, and forest belts. After the strong wind blows, the residual film is blown to the fields and treetops, affecting the rural environmental landscape, causing "visual pollution" and causing adverse effects on the ecological environment
