研究了硫酸铵与有机碳源配合使用对氮素气态损失及植物有效性的影响，试图通过对土壤微生物与氮素相互作用的定量研究，探讨提高氮素利用效率的微生物生物量机制．１材料与方法１．１土样的采集与处理两种土样均采自浙江省龙游县，１号土样属红砂土，土壤有机碳、全氮及有...
The effects of ammonium sulfate and organic carbon sources on nitrogen loss and plant availability were studied. The mechanism of microbial biomass that could enhance nitrogen use efficiency was discussed based on the quantitative study on the interaction between soil microbes and nitrogen. 1 Materials and Methods 1.1 Collection and Processing of Soil Samples Both soil samples were collected from Longyou County, Zhejiang Province. Soil sample No. 1 was red sandy soil with soil organic carbon, total nitrogen and ...
