摘　　要：以菠菜为试材,采用随机区组的方法,研究了牛粪不同施用量对菠菜生长和产量的影响。结果表明:牛粪施用量7 000kg/667m2的菠菜产量最高,达1 227.28kg/667m2,较不施肥(对照)增产24.32%;牛粪施用量5 000kg/667m2的菠菜产量次之,较对照增产13.51%;牛粪施用量3 000kg/667m2的菠菜产量第3,较对照增产5.41%,增产差异显著。同时,牛粪不同施用量的菠菜株高、叶面积、叶厚等生长势均优于对照。总之,施用牛粪有效地提高了菠菜产量,改善了菠菜的生长势。Using spinach as experimental materials,random block method,the effect of different application of cow dung on the growth and yield of spinach was studied.Spinach had the highest yield of 7 000kg/667m^2 in the application of cow dung,the highest yield reached 1 227.28kg/667m^2,with no fertilization（CK）increased by 24.32%;application of cow dung of 5 000kg/667m^2,13.51% higher than CK;application of cow dung of 3 000kg/667m^2 of spinach yield was the third,yield increased by 5.41%than CK.The increasing of yield was significantly different.At the same time,different application amount of cow dung on spinach plant height,leaf area,leaf thickness growth potential was better than the control.In short,the use of cow dung could effectively improve the yield of spinach,improve the growth potential of spinach.
