A mechanized technique of ecological soil planting for the annual double cropping of wheat and maize with a five-year cycle.

An ecological soil planting method was proposed for the annual double cropping of wheat and maize with a five-year cycle. This method is suitable for Huang-Huai-Hai Region and aims to address the problems of reduced crop yield and soil crust as a result of soil and water loss, deteriorated land fertility, and protective tillage in intensive cultivation. Moreover, the planting specifications of the annual double-cropping rotation patterns of wheat and maize were unified, and the key agricultural equipment was designed for full mechanization. Research results on the test demonstration base showed that the return of straw to the field and scientific fertilization can limit the emissions of harmful gas and the use of fertilizer. Furthermore, these steps can enhance ecological agricultural production. The return of straw to the field and suitable cultivation can increase the content of organic matters in soil, improve the aggregate structure, and enhance soil fertility. Finally, the implementation of the ecological fertile soil planting technique can overcome the disadvantages of intensive cultivation and protective tillage, thereby facilitating stable and high crop yield.
