| 摘 要： | 在甘肃河西绿洲灌区,通过田间试验研究了增施绿肥7500kg/hm^2后减施无机N肥施用量对小麦产量、经济性状、土壤肥力和土壤微生物数量的影响。结果表明,绿肥＋70%N处理比当地农民习惯施肥模式（FFP）增产829～1525kg/hm^2,增产率为10.7%～22.9%,且土壤碱解N、速效P、速效K和有机质含量均较高,能... |

| 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 microor... |
