桐粕基生物有机肥对几种旱地土壤钾素养分状况的影响
Effects of Tung Meal Microbial Organic Fertilizer on the Potassium of Several Kinds of Upland Soil
摘要
Abstract
Microbial organic fertilizer is made of potassium bacteria and degraded tung meal. Three kinds of upland soil are treated with potassium bacteria and microbial organic fertilizer under room temperature for 100 days to testify the change of available K and slowly available K. The results of the research dem- onstrate that the microbial organic fertilizer significantly enriches available K, and the increase is related to the supply level of the soil itself; the microbial organic fertilizer also promotes the transformation from slowly available K into available K, while potassium bacteria degrade mineral potassium. As a result, the quantity of available K and slowly available K rises synchronously.关键词
