Potassium Fertilizer Application Increased the Accumulation of Potassium During Reproductive Stages in Different Parts of Vegetable Soybean(Glycine max L.Merr. )
With normal rates of N and P fertilizers,we treated two vegetable soybeans Zhongkemaodou 1 and cv. 121 with no potassium fertilizer( K0),120 kg·ha- 1K( K1) at seeding,120 kg·ha- 1K with additional foliar application of 30 kg·ha~(- 1)of K2SO_4( K2),and investigated the dynamic of potassium accumulation in leaves,petioles,stalks,pods and seeds within28-56 days after flowering respectively. The results showed that the potassium accumulation was characterized by K2 > K1 >K0 and seeds > pods > stalks. It was als...
