Abstract:

In order to increase maize yield stimulative farmer is added close, more scientific and rational application of nitrogen to reduce the pollution to environment, through field randomized block experiment, studied the compound fertilizer, slow-release fertilizer and compound fertilizer of 3 kinds of nitrogen fertilizer on summer corn yield and panicle traits influence. The results showed that,3 kinds of nitrogen fertilizer can make the summer maize yield, effective panicle number, grain number per spike and significantly improve; from the net income and the efficiency of fertilization level, applying fertilizer, compound fertilizer, slow-release fertilizer, From the output and economic benefits compared to the best effect, application of compound fertilizers.
