| 摘 要： | 采用盆栽试验研究缓释复合肥料(SRF)对酸性菜园土壤微生物数量特征的影响。两次测定(35d和45d)结果表明,在各处理中,SRF处理土壤微生物量碳(SMBC)含量、细菌和放线菌数量均为最高,其中SMBC达到显著;SRF处理微生物量氮(SMBN)含量显著高于普通复合肥(CCF)处理(分别提高25.8%和38.6%),真菌数量低于包膜缓释肥(CRF)处理,高于CCF处理;与施用普通复合肥(CCF)处理相比,SRF能够显著提高白菜产量(分别提高16.4%和13.9%),而与包膜肥料CRF处理无显著差异。 |

| Abstract: | Slow/controlled release fertilizers are new type of fertilizer with optimum nutrient uptake by crops,fertilization conveniently and higher recovery of fertilizer than common chemical fertilizer.In a pot experiment,the organic material-based uncoated slow release compound fertilizer(SRF) produced by the Southwest University was adopted to study the effect of slow release compound fertilizer on quantitative characteristics of microorganism in acidic garden soil.Results showed that SRF could increase the numbe... |
