摘要：

以应用生物肥料培肥水稻育秧苗床，研究培肥方式对不同土壤酶活性的影响。结果表明：普通水稻土进行培肥处理后作为水稻育秧苗床，秧苗期土壤脱氢酶、脲酶、纤维素酶、蛋白酶的活性增强，硝态氮含量明显提高，其中采用生物肥料快速培肥比常规营养土效应明显。而盐碱土采用生物肥料快速培肥处理的土壤脱氢酶、脲酶、蛋白酶活性及硝态氮含量与未培肥的普通水稻土差异不大。说明采用生物肥料快速培肥有利于提高土壤酶活性、促进养分转化、提高土壤供肥力，但其培肥效果受盐分的影响。

Abstract:

Effects of different fertilization methods on soil enzyme activities in rice seedling raising bed were studied, which was using biological fertilizer. The main results showed that: the activities of soil dehydrogenase, urease, cellulose enzyme, Protease and Content of Nitrate Nitrogen were significantly increased, and effects of fertility betterment using biological fertilizer were better than normal method, but enzyme activities were no significant difference between saline soil + biological fertilizer and normal Paddy Soil. This result showed that rapid fertilization of seedlings was good to increase the activity of enzyme activity in soil and soil fertility, but the efficiency would be influenced by salt in soil.
