Cultivation Techniques of Low Tillage and High Yield for Peanut-Maize Rotation in Cold Area

The cropping pattern of low tillage and high yield for peanut-maize rotation can solve some problems that long term continuous cropping of maize resulted in soil nutrient imbalance，outbreak of diseases and insect pests in successive years and low economic efficiency.Main operation links were introduced.3 stubbles of peanut and 2 stubbles of maize were planted in 5 years.It had an important significance for increasing crop production value，improving ecological environment and achieving stability and efficiency of food.And it promoted the sustainable development of agricultural ecology.
