| 摘 要： | 添加剂是指为了加快堆肥进程和提高堆肥产品质量,在堆肥物料中加入的微生物、有机或无机物质。本文通过室内培养与室外堆肥试验,研究不同添加剂对猪粪发酵过程中臭味及氮素损失的影响。结果表明,使用本研究中所采用的添加剂与发酵工艺,可以减少猪粪发酵中氨的挥发、氮素损失与猪粪的恶臭。75%含水量的猪粪经过20d的发酵,可达基本腐熟程度。添加剂可以优化堆肥过程的环境条件,提高微生物活性;加快堆肥的腐熟;减少氮素损失,保持养分含量;调节堆肥中各种营养元素的含量,提高堆肥质量。 |
| 关 键 词： | 堆肥 添加剂 氮素损失 |

| Abstract: | Part of the boundary P within the sediments can be released to the sediment interstitial water by decomposing or dissolving. The regenerated phosphate may be released to the overlying water and reprecipitated within the sediment as an authigenic phase, or adsorbed by other constituents of the sediments. The P transferring process on the sediments-water interface was described. On such a basis, the influencing factors and P release mechanisms were summarized briefly in this paper. |
| Keywords: | P cycle Lake sediments Adsorption Release Diffusion of interstitial water |
