应用微生物降低鸡粪N营养元素损失, 促进其无害化进程

Reducing N Nutrient Losses and Enhancing Innocuous Process of Chicken Manures by Microbe

摘要:

为减轻大量禽畜废弃物对环境的污染, 将其资源化为优质的无害化有机肥料, 研究了微生物F468对降低鸡粪N营养元素损失和促进其无害化进程的影响。结果表明, 继代80次, F468降低鸡粪氨气挥发的能力无显著变化, 能降低鸡粪79%的N元素损失。F468还能通过降低蛔虫卵和粪肠杆菌的数量, 促进鸡粪的无害化进程。不添加F468, 蛔虫卵和粪肠杆菌达到我国无害化标准(NY884-2004)的时间分别需要25 d和20 d。加入F468后, 蛔虫卵和粪肠杆菌达到我国无害化标准的时间分别需要15 d和10 d, 均比不加微生物提前10 d达到我国无害化标准。

Abstract:

De-odorizing microbe F468 was used to reduce N nutrient losses and enhance the innocuous process of chicken manures. From its 1st to 80th subculture cycle, F468 showed stable ability to reduce NH3 emission from chicken manures. The total N nutrient losses were reduced by 79% by the addition of F468, compared with that without F468. Moreover, F468 could accelerate the innocent process of chicken manures by reducing Ascaris eggs and Fecal coliforms. Without adding F468, it took 25 days and 20 days for the dead rate of Ascaris eggs and the number of Fecal coliforms in chicken manure to reach the national standard of NY884-2004, respectively. While adding F468, it took 15 days and 10 days for the dead rate of Ascaris eggs and the number of Fecal coliforms to reach the national standard, respectively.
