【摘要】 果园绿肥是一种培肥地力、改善果园生态环境的土壤管理技术,可促进果园健康发展。果园绿肥可以调节土壤含水量,提高土壤对温度的缓冲力,降低土壤容重,提高土壤水稳性团聚体含量;增加土壤碳、氮、磷储量;提高土壤酶活性、微生物活性及数量等。本文从果园土壤理化性质,土壤酶活性和土壤微生物3个方面综述了果园覆盖绿肥对土壤生境的影响,并展望果园绿肥的未来研究方向,旨在为绿肥在果园培肥中的运用提供理论支撑。更多还原

【Abstract】 Including green manure crop in orchardis a soil management technique to improve soil fertility and ecological environment of orchard, which can promote the healthy development of orchard. Including green manure crop in orchard can adjust soil water content, improve soil buffering capacity to temperature, reduce soil bulk density, increase soil water-stable aggregate content, and increase soil carbon, nitrogen and phosphorus storage, and improve soil enzyme activity, microbial activity and quantity. In this paper,the effects of including green manure crop in orchard on soil environment were reviewed from the aspects of soil physiochemical properties, soil enzyme activity and soil microorganism.At last, outlooks of the study on green manure crop growing in orchard were pointed in orderto provide the oretical support for the application of green manure in orchard fertilization.更多还原
