淮北麦稻两熟制受热量资源的限制,季节矛盾突出,特别是淤土地区土质粘重,耕整困难,小麦播种期间常遇阴雨,迟播和烂耕烂种使小麦冬发不足,产量低而不稳。1973年,我所试用免耕法种植小麦,效果良好;1982年秋,进行定点试验,试验地为淤土和砂姜黑土稻茬麦田,以常规翻耕和板茬直播方式(以下称免耕)进行多点多年对比试验。现将三年的结果整理分析如下。 Huaibei double crop of wheat by the heat resources constraints, the contradictions of the season, especially silt soil areas of heavy, difficult farming, wheat often encountered during the sowing rainy, late sowing and bad rotten winter wheat crop less than sufficient yield Low and unstable. In 1973, we tried to cultivate wheat with no-tillage method, and the effect was good. In the autumn of 1982, we carried out the fixed-point experiment to test the stubble and stubble wheat stubble in the silt and black soil. With the conventional tillage and stubble direct- Multi-year comparative test. Now the results of three years finishing analysis is as follows.
