Soybean-corn belt compound planting adopts soybean belt and corn belt intercropping, which makes full use of the lateral advantages of high-position crop corn, expands the space of low-position crops, realizes the coordinated growth of crops, and can effectively solve the land competition problem between corn and soybean by double harvest in one season and multiple beans in one season.
Under the condition of soybean-corn strip compound planting, the yield of corn can be basically reduced and stabilized, and at the same time, one more season of soybean can be harvested, with the yield of soybean 100 kg to 150 kg per mu.
Benefits of Popularizing Soybean-Corn Composite Belt Planting The biggest benefit of corn-soybean composite belt planting is that it can solve the land competition problem between soybean and corn. The ecological benefits of this technology are also very obvious. Soybean rhizobia can fix nitrogen and improve fertility, which can reduce the application of pure nitrogen by 4 kg to 6 kg per mu.
Disadvantages of planting soybean-corn composite belt;
In the field management of soybean-corn strip compound planting, corn and soybean can not use the same herbicide, which leads to the increase of field management cost, the decrease of operation efficiency and the difficulty of mechanized operation.
