| 摘 要： | 应用311A最优回归设计,以黄土母质生土为材料,通过盆钵试验,研究了玉米秸、风化煤、尿素3种土壤熟化措施对生土熟化中土壤微生物量碳的影响。结果表明,在土壤熟化的过程中,玉米秸对土壤微生物量碳的影响在3个因子中最大,尿素次之,风化煤最小;玉米秸与风化煤配合,互作效应非常明显。

Effect of Fertilizing Measures on Soil Biomass Carbon |
| |
| Abstract: | Through the pot culture of loess immature soil ,the comprehensive effects on soil biomass carbon of fertilizing measures of application of maize straw,weathered coal and urea were studied.The results indicated that the biggest effect on soil biomass is maize straw,the second is urea and the last is weathered coal in the process of fertilizing the immature soil.The result of combined application of two kind of materil in proper ration is very good. |
