Cotton no-tillage sowing method suitable for continuous cropping of double cropping of wheat and cotton

Abstract

The invention relates to a non-tillage cotton sowing method suitable for cotton-wheat double-cropping multiple-cropping continuous cropping. The non-tillage cotton sowing method comprises the following steps that 1, reserved lines are arranged among previous-crop wheat sowing belts; 2, watering is performed according to the soil moisture content of the reserved lines in the step 1; 3, 4-8 cm of surface layer soil of sowing areas in the reserved lines is pushed to two sides of each sowing area, and crushing is performed to obtain broken grained soil; 4, furrowing is performed in the sowing areas, and cotton seeds are artificially or mechanically sowed in sowing layers; 5, after sowing, the broken grained soil is returned for coverage and finishing, wherein the returned soil coverage thickness is 2-4 cm, and the sowing areas are finished into M-shaped sowing surfaces with low middles and high sides close to wheat lines. Compared with a common relay intercropping mode, the wheat yield isincreased by about 20% by adopting the non-tillage cotton sowing method. The non-tillage cotton sowing method is suitable for mechanized development of relay intercropping of wheat stubbles or subsequent continuous cropping and ensures one-time sowing full stand, labor for thinning is decreased, the probability of seedling-less ridges is reduced, and an application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of double-cropping and multiple-cropping continuous cropping of crops, in particular to a cotton no-tillage sowing method suitable for double-cropping and multiple-cropping continuous cropping of wheat and cotton. Background technique [0002] my country is a country with a large population and agriculture. Food and clothing are related to livelihood. Without food, there is no stability, and without cotton, there is no ready-made clothing. Under the conditions of a country with a lot of people and little land, how to ensure the output of staple crops such as grain, cotton and oil is very important. In areas with abundant resources such as light, temperature and heat, the development of double-cropping or multi-cropping sowing mode can realize the output and harvest of various agricultural products within a year, greatly improve the utilization rate of natural resources, and increase the yield of crops per un...

Problems solved by technology

In this way, it is relatively unfavorable for the sowing of subsequent crops, and the operation is extremely inconvenient.

The traditional intercropping and sowing methods mostly use manual on-demand sowing or ditching and pendulum sowing to complete the sowing, or a single row of small machines for ditching and planting, but manual advancement or assistance is required. This kind of operation is only carried out on the soil surface. As a result, the emergence rate of seeds in the field varies greatly with the situation of the year, and the emergence is often only about 70%, and even less than 50% in some years, causing crops to be short of seedlings and ridges

However, the above two methods are not aimed at the multi-planting mode of wheat-cotton continuous cropping, and there are problems such as labor-intensive, troublesome management, and unfavorable to mechanized operations.
