牛粪堆肥中添加石灰氮对堆肥发酵的影响
Influence of Lime Nitrogen Added to Cow Dung on Compost
摘要
Abstract
[ Objective ] The research aimed to explore whether lime nitrogen was suitable as a bacteriostatic agent applied in composting. [Method] Static composting system was used, and by means of ventilation and turning, the physical properties of the composting, temperature , moisture, T-N, NH4 + -N/NO3- -N and Escherichia coli number changes were studied, and the effects of lime nitrogen added to cow dung on compost were analyzed. [ Result ] At the end of composting, control group of Escherichia coli were still remnants, and each group of Escherichia coli quickly reached below detection limits. But the treatment group with the addition of lime nitrogen stack nitrogen loss increased, and maturity time was long. [ Conclusion ] During the composting, adding lime nitrogen could extend the composting time, cause feed nitrogen loss increase, but the lime nitrogen as a antibacterial agent with good bactericidal effect, reasonable application in composting treatment need to be further studied.关键词
