摘　　要：为了找出白菜最佳有机肥和氮肥施用量以及白菜对氮磷钾的吸收情况,采用二因素完全随机区组设计进行了研究,并用回归分析方法找出了有机肥量(M)、施氮肥量(N)与白菜产量(Y)之间的关系,结果表明:各处理白菜产量之间差异显著,M1N2处理产量最高,白菜施有机肥过量、施氮肥过量会造成白菜减产;得到了白菜施有机肥量(M)、施氮肥量(N)与白菜产量(Y)之间的回归方程:Y=90317.93377+1.3177976190M+320.2916162N-0.000012412500000M2-0.5345037856N2-0.0012553968254M.N。根据回归方程,当M=40326.85,N=252.26时,白菜产量取得最大值157287.26kg/hm2,符合实际。各处理的白菜植株内全氮、全磷、全钾差异不显著,白菜对氮磷钾吸收取决于品种。In order to find out the cabbage optimum quantity of organic fertilizer and nitrogen fertilizer and cabbage on NPK absorption using two factors in a randomized complete block design,and regression analysis methods was used to find the relationship among the amount of organic fertilizer （M）,the amount of nitrogen fertilizer （N） with cabbage yield （Y）,the results show that： the significant differences between the various processing cabbage production,M1N2 deal with the highest yield, cabbage organic fertilizer overdose,excessive nitrogen fertilization will cause cabbage yield reduce,cabbage organic fertilizer amount （M）,regression equation among the amount of nitrogen fertilizer （N） and cabbage yield （Y） is Y=90317.93377＋ 1.3177976190M ＋320.2916162N-0.000012412500000M2-0.5345037856NE-0.0012553968254M.N,according to the regression equation , when M = 40326.85,N = 252.26,cabbage yield made maximum 157287.26kg/hm2,the result conformity to realistic.The total nitrogen, total phosphorus,total potassium in plants was not significant between all treatment,cabbage NPK absorption depends on the variety.
