缓释复合肥料对酸性菜园土壤微生物数量特征的影响
Effect of Slow Release Compound Fertilizer on Quantitative Characteristics of Microorganism in Acidic Garden Soil
摘要
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 number of SMBC, bacteria and actino-myces in rhizosphere soil on the 35th day and the 45th day compared to the other 3 treatments, and the SMBC reached the remarkable level. The soil SMBN in the SRF treatment was great higher( increased by 25.8% and 38.6%, respectively) than the CCF treatment. The soil fungus number of SRF treatment was lower than coated slow release fertilized CRF) but higher than CCF. SRF could significantly increase the yield of cabbage (increased by 16.4% and 13.9% in two sampling, respectively) compared with CCF, and there was no significant difference with CRF. SRF played a unique role on promoting the reproduction of acidic garden soil microorganisms and improving the structure of functional microorganisms, and then regulating the soil fertility, increasing the growth and yield of crops. SRF is a new type high efficient fertilizer, a friendly ecology coordination agent of acidic soil and an activator of keeping soil good functional microorganism population.关键词
