以稻壳为研究对象,采用单因素试验设计,菌剂添加量为稻壳干物质重量的1%、2%、3%、5%、7%、9%,对稻壳基质化腐熟处理微生物菌剂最适添加量进行研究。结果表明:添加微生物菌剂越多,物料堆体温度达到最高温度的速度越快,但维持的高温时间较短,添加1%菌剂稻壳达到温度最高,为52℃,且高温过程维持时间较长;菌剂不同添加量对稻壳有机质含量、C/N比影响不大,均达到腐熟标准;从基质理化性质、育苗效果及生产成本综合考虑,添加干物质量1%菌剂腐熟效果最好,大规模生产中添加量可减少。
Taking rice husk as the research object, the single factor experimental design was adopted to add rice germ to 1%, 2%, 3%, 5%, 7% and 9% of dry weight of rice husk, The optimum amount of fungicide to study. The results showed that the more microbial agents added, the faster the reactor temperature reached the highest temperature, but the shorter the high temperature time. The 1% rice husk reached the highest temperature of 52 ℃, and the high temperature process maintenance time The results showed that the effect of adding 1% dry matter on the physicochemical properties, seedling-raising effect and production cost was the best. Good, large-scale production can be added to reduce.
