Effect of strip compound planting of corn and soybean on soil environment
Reduce soil erosion 10.6%, reduce surface runoff by 85. 1%, increase soil organic matter content by 5.56%, and increase total nitrogen in corn and soybean soil by 4. 1 1% and 7.29%. Official website of Langfang Academy of Agriculture and Forestry introduced that the compound cropping pattern of corn and soybean has remarkable ecological benefits and is recognized as the best compound cropping pattern in the world. This model can effectively reduce energy consumption, carbon and nitrogen emissions, reduce obstacles to continuous cropping and improve soil fertility through technologies such as no-tillage straw mulching, nitrogen fixation by nodules and regional rotation. Reduce soil erosion 10.6%, reduce surface runoff by 85. 1%, increase soil organic matter content by 5.56%, and increase total nitrogen in corn and soybean soil by 4. 1 1% and 7.29%. Intercropping soybean can fix nitrogen by nodule, reducing urea application by about 4.4 kg per mu, increasing soil total nitrogen content by 4-7% and increasing nitrogen utilization rate by 39%. This has a positive effect on effectively protecting cultivated land and promoting the sustainable development of agriculture.
