摘要
Abstract
The soil water and fertilizer status and maize yield were studied by setting different levels of fertilization. The results showed that the growth and development of maize will be promoted by adding nitrogen and phosphorus fertilizer, and improve the content of nitrogen and phosphorus and the relative content of soil moisture effectively. When the amount of nitrogen and phosphorus is 270 kg/hm2, 90 kg/hm2, respectively, the amount of available nitrogen and effective phosphorus in the soil no longer increases or increases slowly, and the yield of maize will decrease.关键词
