Title: EFFECT OF GREEN MANURE UTILIZATION AND REDUCED N FERTILIZER ON WHEAT YIELD AND SOIL FERTILITY
Abstract: In Hexi oasis region of Gansu province,an field experiment was carried out to investigate the effect of fertilized 7500 kg/hm2 green manure and decreased N fertilizer on wheat yield,wheat chief characteristics,soil fertility and soil microbes.Results showed that the yield was increased by 10.7%~22.9%,829~1525kg/hm2 under the green manure + FFP 70% N than that under the FFP treatment.In addition,the soil available N,available P,available K and organic matter content were much higher,and the number of microorganisms was significantly increased,for instance,the bacteria increased by 62.8% compared with FFP.Applied green manure of 7500kg/hm2 improved the soil fertility and wheat yield when instead of N fertilizer 67.5kg/hm2,which could produce more economical benefit,ecological benefit and social benefit.
