摘　　要：以北方常见不同科属的4种绿肥作物为试材,采用2年定位改良试验方法,研究了绿肥作物不同生育期的土壤化学性质变化,以期为解决当地错季蔬菜种植所造成的环境问题提供参考依据。结果表明:在绿肥生长过程中,其土壤有机质和养分含量增减变化存在差异。相比于第1年,绿肥种植第2年有机质含量提高了10.7%。相较于基础地力而言,种植并翻压绿肥显著降低了土壤有效磷和硝态氮含量,分别降低了34.8%和74.6%,对菜地氮磷累积有显著的削减效果。不同品种绿肥作物对土壤养分含量的影响也存在差异,主成分分析结果表明毛叶苕子处理对土壤养分含量影响最大,春油菜处理次之。Taking four common green manure crops from different families and genera in Northern China as the test materials,and adopted a 2-year positioning improvement test method to study the changes in soil chemical properties of green manure crops at different growth stages,in order to provide reference for solving environmental problems caused by off-season vegetable cultivation.The results showed that there were differences in the changes in soil organic matter and nutrient content during the growth process of green manure.Compared to the first year,the organic matter content of green manure planting increased by 10.7%in the second year.Compared to basic soil fertility,planting and turning green manure significantly reduced the soil available phosphorus and nitrate nitrogen content,by 34.8%and 74.6%,respectively,and had a significant reduction effect on nitrogen and phosphorus accumulation in vegetable fields.There were also different in the effects of different varieties of green manure crops on soil nutrient content.The results of principal component analysis showed that the treatment of hairy leaved sweet potato had the greatest impact on soil nutrient content,followed by spring rapeseed treatment.
