摘要
简要介绍了油-稻轮作、鸭-稻共作、油-稻-鸭种养等3种农业生产模式,总结了不同模式对土壤理化性质、微生物和酶活性的影响,结果表明:油-稻轮作、鸭-稻共作均有助于调节p H,促进土壤团粒结构的形成,提高土壤中有机质、碱解氮、有效磷、速效钾的含量,提高土壤微生物数量及酶活性,提高土壤肥力,改善土壤理化性质.目前关于油-稻-鸭生产模式报道较少,但该模式有助于土壤磷的积累,其对土壤的其他贡献有待深入研究.
Three agricultural production modes:rape-rice rotation,duck-rice co cropping and rape-rice-duck breeding were briefly introduced, and the effects of different modes on soil physical and chemical properties,microorganisms and enzyme activities were summarized. The results showed that rape-rice rotation and duckrice co cropping were helpful to adjust soil pH,promoted the formation of soil aggregate structure,improved the contents of soil organic matter,alkali hydrolyzable nitrogen,available phosphorus and available potassium in soil,increased the number of soil microorganisms and soil enzyme activity,improved soil fertility and its physical and chemical properties. At present,there are few reports on the rape-rice-duck production model,but this model contributes to the accumulation of soil phosphorus,and its other contributions to soil need to be further studied.
