Effect of Different Fertilizer Application on Summer Corn in Guanzhong Area

The corn production and related plant traits results of six fertilizations were analyzed in this test,such as high-nitrogen compound fertilizer,the new BB fertilizer,controlled-release fertilizer,fertilizer optimization(NPK ratio),single application of nitrogen fertilizer and no fertilizer(CK) level.It is found that application of high-nitrogen compound fertilizer,the new BB fertilizer,N,P,K fertilizer(optimized ratio) can increase the plant stem diameter and light green leaves,grain weight and improve plant productivity,significantly increased maize grain yield and straw yield.Especially in high-nitrogen compound fertilizer and a new BB more obvious advantages,respectively,than the optimal management of fertilizer application(NPK appropriate ratio) increased 4.42%,2.31%,respectively,than a single application of nitrogen fertilizer to deal with increased 12.25% and 11.69%.This showed that application of high-nitrogen compound fertilizer,the new BB fertilizer is summer corn inGuanzhong area of Shaanxi Province to further simplify light efficient fertilizer choose the direction of cultivation.
