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

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.
