Abstract

Based on many years researches in the field, the experiment was conduded to study the effects of the different fertilizer on winter wheat and summer maize growth and yields. The results showed that EM micxobial compost increased winter wheat and summer maize yields significantly. The annual average yield of EM microbial compost treatment was 8.3%-8.9% higher than the same amount traditional compost treatment, and 8.3% higher in winter wheat and 8.2%-9.4% in summer maize. EM microbial compost could decrease soil hulk density, increasing soil water content and improving the environment of crop growth. EM microbial compost could enhance winter wheat leaf area duration obviously. The total leaf area duration of the EM microbial compost treatment were 5%-36% for winter wheat and 5.2%-14.3% for summer maize higher than the same amount traditional compost treatment, 19%-72% and 19.6%-46.4% higher than fertilizer treatment, respectively. The diffences were more obvious as the amount of EM microbial compost applied increasingly. The higher leaf area duration of EM microbial compost improved dry matter accumulation rate and advanced crop growth rate.
