农牧交错区保护性耕作技术试验研究

Conservation Tillage in the Interlock Region of the Farming Area and Pastoral Area

主要论述了保护性耕作技术在农牧交错区实施的农艺与机械化技术方案、措施及实施效果。以农牧交错区的典型代表武川地区为例,分析了农业机械化技术模式,总结了实施效果。经检测,麦类增产75～90kg/hm2,增幅为7%左右;油菜籽增产45～120kg/hm2,增幅为4%～7%;马铃薯由于带状保护而增产约900kg/hm2,增幅为6%左右;节省作业费50～255元/hm2;增收节支效益为270～480元/hm2。实施保护性耕作技术可减少风蚀30%～60%,减少地表径流30%左右,对防治沙尘暴、改善农牧业生态环境和实现农牧业可持续发展起到了重要作用。

A scheme and measure of the agronomy and mechanization technology for the implementation of conservation tillage in a region where the farming area and pastoral area interlock and the implementation effect were narrated in this paper. The territory of Wuchuan County is a typical district that is the farming area and pastoral area interlock. Hence, paper analyzes the mode of agricultural mechanization technology, and summaries its implementation effect. The result of inspection reveals that the yield increase and the increasing rate are 75-90kg/hm^2 and 7% for wheat; 45 - 120kg/hm^2 and 4 - 7% for rape; 900kg/hm^2 and 6% for potato being implemented with a belt pattern conservancy respectively and the reduction of operation cost is 50 - 255yuan/hm^2, the benefit increase 270- 480yuan/hm^2, the wind erosion of farmland is lightened by 30- 50% and the surface runoff by 30%, and thus the conservation tillage plays a significant role on the prevention of sand ＇storm, the improvement of ecological environment in the farming area and pastoral area and the realization for agriculture and animal husbandry to keep up steady and continued development.
