潜育性水稻土是湖南主要低产田,占稻田面积40%左右,一般比非潜育性水稻土每亩减产100-300斤,严重阻碍农业生产的发展。近几年,我省组织了对潜育性水稻土成因与改良的研究。土壤微生物和土壤酶都是综合评价土壤肥力的主要指标,我们配合研究了潜育性水稻土的微生物特性和酶活性。 The gneissic paddy soil is the main low-yield field in Hunan, accounting for about 40% of the paddy field area, generally reducing 100-300 kg per mu than the non-gneisonic paddy soil, which seriously hinders the development of agricultural production. In recent years, our province has organized the study on the causes and improvement of the gneissic paddy soil. Soil microorganisms and soil enzymes are the main indicators for comprehensive evaluation of soil fertility. We cooperated to study the microbial characteristics and enzyme activities of the gneissic soil.
