Coupling effect of water and phosphorus on physiological indexes of summer maize
Four coupling experiments of water and phosphorus were carried out in Yuxi district in order to study coupling effect of water and phosphorus on detached leaf, plant height, growth rate, blade, dry matter, content and absorption of N, P and K in seedling stage of summer maize. The results showed that the coupling experiment with high soil water content and high P content (HH) could made the physiological indexes of summer maize have the best growing state among them. And the LH had the second best one and much better than ones in the HL and the LL. Conversely, the growth state in the LL was the worst among them. Eventually, the HH was suggested to be done so as to make summer maize have better growth state in seedling stage and other growing stages of summer maize in Yuxi district in the future.
