微生物菌剂对草屑堆肥养分的影响

目的]筛选适宜在草屑堆肥中应用的微生物菌剂,以加速草屑的资源化利用。方法]添加不同微生物菌剂到草屑中,测定不同处理时间堆体温度和营养元素含量的变化。结果]添加微生物菌剂影响堆体的升温过程和降温过程,未添加微生物菌剂的对照在堆肥化过程中升温慢、降温快;添加不同微生物菌剂的堆肥中的养分含量变化不同,其中添加速腐宝菌剂和秸秆腐熟剂处理的堆肥总养分含量高于其他菌剂和对照;以草屑为原料生产的堆肥中总养分含量较高,高于有机肥料的标准。结论]在草屑堆肥化过程中,应用速腐宝菌剂可提高堆肥养分含量。

Effects of Microorganism Agents on Nutrient Content of Turfgrass Clippings Composting

Objective] The goal of this research was to select microorganism agents for the compost of turfgrass clippings and accelerate the usage of turfgrass clippings as a recycle resource.Method] Different microorganism agents were added into turfgrass clippings respectively and temperature and nutrient content in the composts of different treatment time were determined.Result] The addition of microorganism agents significantly affected the changes of the temperature in the composts.The contrast,no microorganism agents,had the slower temperature rise and faster temperature drop.The nutrient content of the composts were different among several microorganism agents treatments.The highest nutrient content was found in the composts added with Sufubao microorganism agent and Straw starter culture,and total nutrient content in the lawn chipping compost was higher than the standard nutrient content of organic fertilizer.Conclusion] Sufubao microorganism agent can enhance nutrient content in maturity compost and outstanding effects are expected in actual application.
