The Impact of on Chinese Cabbage Yield and NPK Absorb in Different Nitrogen Fertilizer and Organic Fertilizer

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-0.000012412500000M2-0.5345037856N2-0.0012553968254M.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.
