摘要
晋西北河曲县砖窑沟流域栗褐土上连续7年定位施肥试验的增产和培肥效应分析表明:连续施肥与CK相比,增产幅度有增大趋势,而且抗逆性增强。有机肥与无机肥合施的增产和培肥效应最明显,多年平均增产幅度是CK的1.5倍。有机肥与氮肥合施的增产效应最大。高量有机肥与氮肥合施的培肥效果最好,多年平均增产效应是CK的2倍。
Based on the consecutive located fertilization of 7 years on chestnut-cinnamon soil in Zhuanyaogou vvatershed Northwestern Shanxi,the effects of increasing soil fertility and crop yieldwere studied.The results showed that the increasing yield range became higher after fertilizingthe soil consecutively,and the soil adversity resistance was improved.The effects of increasingsoil fertility and crop yield by using mixttire of organic and inorganic fertilizer;were much moresignifacant than using the organic only-or一only inorganic fertilizer,and the former’s increasingyield range on average was 1.5 times as great as the control;The application of manure mixedwith nitrogen was the best for increasing crop yield.The application of high level manure withnitrogen fertilizer had the best effect of increasing soil fertility,which was 2 times great as thecontrol.
