摘要：世界各国研究认为，绿肥是一种很好的生物肥料。它能较好的生长在氮素不足的土壤中，并供给其他作物以充足的氮素。当绿肥作物翻压到土壤中，可以使土壤中的有机质丰富。绿肥在维持土壤肥力方面也起着重要作用，其价值超过其他培肥方法，因为绿肥一般都是就地生长，就地翻压，没有运输上的损失。1973年F.E.Allison综合各国情况，归纳了绿肥的作用主要有以下几方面：①固定空气中的氮素，丰富土壤中氮素养分;②促进土壤腐殖质的形成，提高土壤有机质含量；③改善土壤物理性状；④富集土壤中养分；⑤为农作物提供部分碳素营养；⑥防止土壤侵蚀和养分流失；⑦防止植物病害和可能产生的有害的化学和生物学的影响[2]。

Green manure and the role of tobacco production in the application of Progress
Abstract: The countries in the world on that green manure is a good biological fertilizer. It can better growth in the lack of nitrogen in the soil and other crops to supply adequate nitrogen. When the green manure crop up pressure to the soil, soil rich in organic matter. Green manure in the maintenance of soil fertility has also played an important role, and its value more than other fertilization methods, as green manure are generally in situ growth, locally up pressure, no transportation losses. 1973 FEAllison comprehensive national circumstances, summed up the role of green manure in the following areas: ① fixed nitrogen in the air, soil rich in nitrogen nutrients; ② promote the formation of humus soil, improving soil organic matter content; ③ improve soil physical Characters; ④ enriched soil nutrients; ⑤ for some crops to provide carbon nutrition; ⑥ prevent soil erosion and nutrient loss;
