添加复合微生物堆肥腐熟剂对青藏高原高海拔地区鸡粪发酵的影响
Effect of Adding Composite Microbial Compost Maturation Agents on the Fermentation of Chicken Manure in the High Altitude Region of the Qinghai-Xizang Plateau
摘要
Abstract
The study aims to investigate the effects of adding a composite microbial compost maturation agent on the fermentation of chicken manure in the Qinghai-Xizang Plateau region.The results showed that the addition of microbial agents increased the fermentation temperature and accelerated the degradation rate of organic matter during the composting process.Within 72 h of fermentation,the temperature of the treatment groups with microbial agents could rapidly rise to around 50℃.After about 11 days of fermentation,another peak of temperature between(45-50)℃ was observed,followed by a gradual decrease in temperature.After composting,the oxygen content and the content of available phosphorus and potassium in these treatment groups increased.The available phosphorus content in the WT3 treatment group in-creased from 980.9 mg/kg to 1260.1 mg/kg,which was 7.9％and 12.8％higher than the control groups CK1 and CK2 without microbial a-gents,respectively.The available potassium content with WT3 group also increased by 6％and 15.2％,compared with CK1 and CK2,respec-tively.Among them,the available phosphorus content in WT3 treatment group increased by 7.9％and 12.8％compared with the CK1 and CK2 control groups,respectively,and the available potassium content also increased by 6％and 15.2％,respectively.Seed germination exper-iments indicated that the compost from the microbial agent treatment groups had a good promoting effect on seed germination,and the germi-nation rate was more than 90％,while that in CK2 group was only 55％,which was significantly higher than that in the control group.In con-clusion,the homemade microbial agents and commercial microbial agents had similar effects,both of which can accelerate the composting process and improve the quality of the compost.关键词
