| 摘 要： | 为探索适合凤城地区的玉米保护性耕作模式,在抓好示范区建设的基础上,以传统耕作技术模式为对照,进行保护性耕作应用效果试验。试验结果表明:保护性耕作可明显提高耕地土壤的含水量和微生物活性,具有增肥地力和增加玉米产量的作用;高留茬模式是凤城地区的主导技术模式;而碎秆覆盖模式适于在风力较小、秸秆资源丰富地区施用。

| Abstract: | In order to work out proper protective cultivation models suitable for Fengcheng area, experiments were conducted on the application effects of protective cultivation techniques with the traditional methods as its control group. The results show that protective cultivation can substantially improve soil moistures and the activity of microorganisms which, in turn, is likely to increase soil fertility and maize yields. The pattern of remaining high stubbles is a dominant technical model adopted in Fencheng area while the pattern of covering with smashed stalks is fit for places where the wind strength is relatively weak and the stalks are abundant. |
