稻作制与有机肥对红壤水稻土微生物及酶活性的影响研究

长期定位试验研究稻作制和有机肥对红壤水稻土微生物数量及酶活性的影响结果表明 ,不同稻作制和有机肥施用量对土壤微生物组成和数量的影响不同。良好的稻作制和适量有机肥可提高土壤酶活性和土壤肥力。

Effects of rice based cropping system and organic manure on microbes and enzyme activities in paddy soils derived from red earth

The effects of the rice-based cropping system and organic manure on microorganisms and enzyme activity in paddy soils derived from red earth were studied. The results show that the three main groups of microbes in soils and some special physiologic groups microbes are obviously affected by different cropping systems and organic manures. The enzyme activities in paddy soils derived from red earth and soil fertility can be improved by the optimal cropping system and organic manure.
