玉米是一种高产作物,适应范围广,随着人口增多对粮食的需要,玉米栽培面积不断扩大,势必造成连作现象。经我们多年研究,玉米适当连作并不减产;由于根茬还田和秸秆还田,土壤肥力也不会因玉米连作而下降。应充分发挥玉米在农田生态中的积极作用,保持地力常新,改进裁培技术,不断提高玉米的产量。
Corn is a high-yield crop with a wide range of adaptability. As the population increases its demand for food, the area for corn cultivation will continue to expand, which will inevitably cause continuous cropping. After years of our research, proper cropping of corn does not reduce production; because of the availability of stubble and straw, soil fertility will not decrease due to continuous cropping. We should give full play to the positive role of maize in farmland ecology, maintain a new environment, improve cutting techniques and continuously increase corn output.
