Plastic film mulching machine for cotton furrow sowing in saline-alkali soils

Abstract

The invention discloses a method for mulching plastic films for cotton furrow sowing in saline-alkali soils, which comprises the following steps: A, ridging on sowing belts, ditching and fertilizing on the bottoms of the ridges, and ditching to seed 3 to 6cm staggered with fertilization furrows, then carrying out earth backing and compacting on the sowing furrows; and B, ditching film mulching furrows at the two sides of the sowing furrows, and mulching plastic films on the top of the ridge between two sowing furrows. The Plastic film mulching machine for realizing the method of the invention comprises sowing/fertilization assemblies and a mulching film assembly, wherein the mulching film assembly is arranged between two sowing/fertilization assemblies and used for mulching plastic films on the top of a ridge between two sowing furrows. Because the mulching films on the ridges can reduce soil evaporation and have the function of rainwater collection, invalid soil evaporation can be restrained effectively, and the transfer of salts to plough layers can be restrained effectively in the areas that the soils are high in salt content, thereby achieving the purposes of gathering part of salts in the top of ridge and reducing the salt content of cotton roots.

Description

technical field [0001] The invention relates to a cotton furrow-sowing film-covering method and a furrow-sowing film-covering machine for realizing the method, especially suitable for cotton planting in saline-alkali land, and belongs to the technical field of agricultural machinery. Background technique [0002] The Bohai Rim Plain is located at the forefront of my country's Bohai Rim Economic Circle, and is an important agricultural product production area and reserve arable land resource area in China. In view of the problems of high salinity in the soil, severe shortage of fresh water resources, frequent droughts, and abundant salt water resources, low utilization rate, single utilization mode, and low efficiency, the main crops of grain, cotton, fruits and vegetables such as wheat, corn, cotton, For the safe planting of fruit trees and vegetables and the improvement of the regional environment, the research and development of new types of salt water supporting agricultu...

AI Technical Summary

Problems solved by technology

The planting of crops in high-salt areas has its special environment and agronomic requirements. At present, the agricultural machinery in this area is only barely used after some conventional farming machinery has been properly improved. The pertinence is not strong, and there is no special agricultural machinery for operatio
