Fertilizer Effects and Fertilizer Use Efficiency of Chinese Cabbage Jincai No.1

3414 field fertilizer test was conducted to study the effects of N,P and K fertilizer on yield and economical efficiency of Chinese cabbage Jincai No.1 as well as the fertilizer use efficiency.The results showed that reasonable utilization of N,P and K fertilizer could increase the yield obviously.The yield of Chinese cabbage Jincai No.1 could be increased by as high as 6 417 kg/hm2 by reasonable utilization of N,P and K fertilizer,while the increase of pure income was 18 148.5 yuan/hm2.The dose of fertilizer in practice should not be increased blindly but applied according to soil fertility and need of Chinese cabbage so that the formulation of N,P and K fertilizer was reasonable and loss of fertilizer could be reduced.Meanwhile,enhancement of soil fertilization was essential.
