摘要
冬季绿肥是一种养地作物,是一种重要的优质生物肥源和有机肥料。我国南方稻区水、热资源丰富,多数地区适宜种植冬季绿肥。为了深入研究冬季绿肥作物对稻田生态环境效应的影响,在前期田间试验研究的基础上,结合众多学者的研究进展,综合阐述了冬种绿肥条件下水稻氮素吸收和利用、土壤养分、土壤微生物生物量和活性、土壤有机碳及碳库管理指数、稻田病虫草害及其稻田温室气体排放等方面的研究,以期为大面积推广种植冬季绿肥、发展绿肥生产和实现农业的可持续发展提供一定的理论依据。
Winter green manure is a kind of crop raising soil fertility, and it is an important source of high-quality bio-fertilizer and organic fertilizer. The water and geothermal resources are rich in southern areas; most areas are suitable for planting winter green manure. In order to study the impact of winter green manure on the ecological environment, on the basis of preliminary field trial, we reviewed the research progress of many scholars, and described the effects of winter green manure on nitrogen absorption and utilization of rice, soil fertility, soil microbial biomass and activity, soil organic carbon and carbon management index, paddy pests, greenhouse gas emissions and other aspects. The paper provides a theoretical basis for planting of green manure in large scale, the development of green manure production and achieving sustainable development of agriculture.
