基于灰色关联投影法的保护性耕作技术模式综合评价

利用灰色关联投影法对黑龙江西部风沙土区保护性耕作技术进行综合评价。试验区选在黑龙江省杜尔伯特县一心乡,保护性耕作措施处理包括行间覆膜、行间覆膜与垄向区田的集成、垄向区田、秸秆覆盖,以常规耕作处理为对照,目的在于研究建立适合于当地的保护性耕作技术模式,为黑龙江西部风沙土区农业水土资源可持续利用提供技术支撑。研究结果表明4种保护性耕作措施均有不同程度的节水和提高经济效益的作用。不同措施的综合效果为：行间覆膜与垄向区田集成措施〉行间覆膜措施〉垄向区田措施〉秸秆覆盖措施〉常规处理措施。

Comprehensive Evaluation of Different Conservation Tillage Based on Grey Relation Projection Method

The purpose of the author was to use the grey relation projection method to evaluate the conservation tillage in western aeolian sandy soil area of Heilongjiang Province.The experimental field was elected in Dumeng Country Yixin town.The measure of the conservation tillage including covering film between furrows,integration technique of ridge tillage and covering film between furrows,ridge tillage,straw mulch.The purpose is to establish an appropriate conservation tillage technology model in this area.The results show that the four kinds of conservation tillage have different effect of water-saving and improve economic role.Their effects were that：,integration technique of ridge tillage and covering film between furrowscovering film between furrowsridge tillagestraw mulchCK.
