摘要
对大型养猪场正常运行沼气工程产生的沼液进行了肥效分析,得出大型养猪场沼气工程沼液中的有机质含量达到0.9%,总养分达到0.2%,经厌氧处理后沼液的蛔虫卵死亡率达到100%,大肠菌群数减少99%以上。用于水稻浸种西红柿和油菜的种植,能产生明显增产作用,西红柿产品优质率提高35%,油菜产品优质率达到36%。
Fertilizer efficiency of biogas slurry from biogas engineering on a large-scale pig farm was analyzed. The result showed that the slurry had organic content of 0.9%, total nutrient content of 0.2%. Applying slurry to tomato and rape, or soaking the rice seed with slurry, could significantly increase their production. The high grade rate of tomato increased by 35%, and that of rapeseed increased by 36%.
