The results showed that at mature stage, for the N2K2(N 150 kg/ha + K2O 100 kg/ha) treatment, dry matter accumulation of stems, leaves, spike, grain, translocation amount, efficiency and contribution rate of stems were all higher than that of other treatments. Yield, protein and starch contents in N2K2 treatment were also improved. Therefore, N and K ratio of 150 kg/ha, 100 kg/ha was conducive to increase dry matter accumulation, yield and quality of corn in cold area.Read More
