Research on maize higll-yielding culture mode with applying fertilizer in extractive quantity to control nonpoint-source pollution

  • Using the orthogonal quadratic regression design method,a cultivation technology mode to retain maize high yield with applying fertilizer in extractive quantity is found out,by which nonpoint-source pollution can be controlled.From the research result,a numeric rllode of the density of maize planting,quantity of applying N and quantity of applying P is built,and the applying technologies of fertilizer are defined including deep hole-application of P fertilizer and deep application of N fertilizer for the rapid growth of its ears.
