耕作方式和有机肥对风沙土区玉米产量的影响
Effect of Tillage Method and Organic Fertilizer on Maize Yield in Aeolian Sandy Soil
摘要
Abstract
[Objective] Effect of tillage method and organic fertilizer on maize yield was studied.[Method] The present study was carried out at the agricultural science and technology park of Durbat Mongolian Autonomous County in Daqing,Heilongjiang Province.Three types of fertilization,including chemical fertilizer,chemical fertilizer plus straw returning,and chemical fertilizer plus organic manure,associated with five tillage managements,which were no-tillage,conventional tillage,breaking plow bottom,subsoiling and deep subsoiling,were designed randomly.Yield of maize,soil infiltration capacity,bulk density,three-phase ratio and penetration rate were determined.[Result] Adjusting soil physical characters through tillage management had less effect on maize yield.Under same tillage management condition,chemical fertilizer plus organic manure increased maize yield by 19.2%-32.9% than chemical fertilizer alone,and by 7.4%-189.0% than chemical fertilizer plus straw return.In conclusion,in aeolian sandy soil of northeast China,applying organic manure was the most effective method for increasing maize yield,but the effect of straw returning was not obvious;conventional tillage 20 cm was the optimal method.[Conclusion] The best strategy was chemical fertilizer plus organic manure associated with 20 cm plowing in aeolian sandy soil of northeast China.关键词
