摘要
Nutritional accumulation mainly occurres from growth stage 2 to stage 3(lotus-setting stage to early heading stage, 48 - 72 days after transplanting)in Chinese cabbage. The uptake ratio of N and K is nearly l:l,and their uptake amounts are obviously higher than that of P. Balanced fertilization .especially the suitable combination of N and K,is important for the production of high yield and high quality.
