摘　　要：以二月兰、白三叶、小冠花、百脉根、毛叶苕子和油菜为供试绿肥、以清耕为对照，在晋南灌溉果园进行了连续28的研究。结果表明，在晋南灌溉果园套种绿肥均能增加果园地面覆盖、抑制杂草的生长，提高0-20cm土壤蓄水保墒能力和有机质含量，套种二月兰、白三叶、小冠花、百脉根和毛叶苕子后土壤全氮、碱解氮与速效磷含量均有小幅增加，套种油菜后土壤中的全氮、碱解氮和速效磷含量略有降低。综合2a试验结果，二月兰和白三叶2种绿肥春季返青早、耐阴、生长快，地面覆盖、蓄水保墒和培肥土壤效果好，抑制杂草效果显著，只需一次播种即可自然快速扩繁，管理简便，适合在晋南灌溉果园推广。The experiment was carried out to screen appropriate green manure for irrigation orchard in southern Shanxi. Orychophragmus violaceus, Trifolium repens, Crown vetch, Lotus japonicus, Vicia viUosa and oilseed rape were used as trial green manure crops with clean tillage as control. The result showed that interplanting green manures at irrigation orchard could increase the orchard ground cover, restrain weeds, and increase soil organic matter contents. Interplanting of Orychophragmus violaceus, Trifolium repens, Crown vetch, Lotus japonicus and Vicia villosa could improve the soil total nitrogen, available nitrogen and available phosphorus content. Whereas, interplanting of oilseed rape could reduce the total nitrogen and the available contents of nitrogen and Phosphorus in soils. Based on the two-year experimental results, two green manures of Orychophragraus violaceus and Trifolium repens could get early green turning in spring, shade tolerance, quickly growth, ground cover, soil conservation, and restrain weeds. Only one seeding could be naturally fast propagation, management is convenience, suitable for extension in southern Shanxi irrigation orchard.
