A kind of wheat intercropping corn planting method

Abstract

The invention relates to a wheat intercropping and corn planting method, comprising the following steps: Step 1: fertilizing the land and preparing the land in the spring of that year, sowing wheat between March 10-20, and intercropping between April 10-20 Cover the corn with mulch and irrigate regularly; step 2: when the wheat in step 1 is mature, leave 25-30 cm of stubble and return the wheat straw to the field after harvesting for annual mulching; step 3: when the wheat in step 1 After the corn is harvested, the mulch is recycled for annual mulching; step 4: no-tillage hard stubble sowing in the next year, and steps 1, 2 and 3 are repeated. Reduce wind erosion and maintain high soil water content, which is used for the growth and development of next crops and improves water production efficiency. Straw returning to the field can increase the content of soil organic carbon, which is beneficial to fertilize the soil. At the same time, no-tillage reduces carbon input and carbon emissions, and realizes sustainable agricultural development.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a wheat intercropping corn planting method. Background technique [0002] In the arid inland oasis irrigation area, wheat and corn are the two main crops, and the sowing ratio is greater than 50%. Due to the serious water shortage of resources, the intercropping planting mode is adopted to improve the resource utilization efficiency by increasing the output rate per unit area. However, the high yield of traditional intercropping depends largely on the excessive input of purchased resources such as chemical fertilizers, irrigation, plastic film, and mechanical power to achieve high output. Negative effects such as ecosystem degradation, biodiversity reduction, and poor system stability have significantly reduced the quality of cultivated land and regional ecological carrying capacity, reducing the potential for high and stable crop production.
