Study on N -P -K fertilizer efficiency and its optimum rates for Chinese cabbage
Abstract：Field trials on fertilizer efficiency to Chinese cabbage were carried out by using ＂3414＂ fertilizer experiment design. The results showed that nitrogen and potassium gave more influence to the yield of cabbage than phosphorous, the optimum fertilizer rates of N, P2o5 and K20 for the economic benefit were 15, 4.8 and 14 kg/667m2 （225, 72 and 210 kg/hm2） respectively, and the yield was 2,709kg/667m2 （40. 635 kg/hm2） and the benefit was 3 361. l lyuan/667m2 （50416.65 yuan/ hm2 ）.
