【摘要】 对传统耕作法进行了辩证分析,识为引起西部地区干旱,水土流失,沙尘暴,土壤肥力递减的主要原因是传统耕作法所致,提出了提高保蓄自然降水解决农田干旱的理论并研究出仿森林生态原理的"留茬免耕秸秆全程覆盖"耕作新技术。该技术提高了自然降水的保蓄率,防止了水土流失和沙尘暴,提高了土壤肥力,经济生态和社会效益明显,将农业生产和治理生态统一起来,达到了人与自然和谐相处,它将是我国西部地区农业可持续发展的必由之路。更多还原

【Abstract】 Traditional farming methods weye analysised,The western drought,caused by drought,soilerosion,dust storms,soil fertility decline,is mainly due to the result of traditional farming method.Made with natural precipitation to increase security solution theory arid farmland,and principles of forest ecosystems studied imitation of"on-tillage stubble straw delay full coverage"of new farming technology,the technology of natural precipitation to increase with the rate of secruity to prevent the soil erosion and economy ecological social is obvious.It will be the only way for the sustainable development of agriculture in the western region of China.更多还原
