摘要
Abstract
In order to know the pollution situation of sheep dung to the environment,the seasonal variation of major pollution indicators in the feces of Dorper sheep and Small-tailed Han sheep were analyzed.The results show that the main component of feces had a significant seasonal variation.For Dorper's feces,they had the highest organic matter,total phosphorus,copper content in summer,respectively 90.21%,0.90%,43.20 mg/kg;In autumn,the highest was total nitrogen content,which could increase up to 2.44%;The zinc content was the highest in winter,at 162.0 mg/kg,which were significantly higher than other seasons;All these indexes were minimum in spring.For Small-tailed Han sheep,their feces contained organic matter,total nitrogen,zinc respectively 90.11%,2.28%,203.9 mg/kg in autumn,which were the highest in whole year.In summer,total phosphorus,copper content was the highest,being 0.91%,49.32 mg/kg,respectively.Organic matter,total nitrogen and total phosphorus were the lowest in spring.And the content of copper and zinc were the lowest in winter.There was no significant difference (P>0.05) for the content of organic matter,total nitrogen,total phosphorus and copper for these two species' feces except Small-tailed Han sheep had a significant higher zinc content (17.7%) than Dorper's feces.关键词
