【摘要】：以黑土為研究對象,采用室內(nèi)培養(yǎng)方法,研究阿特拉津?qū)谕岭迕�、轉(zhuǎn)化酶、多酚氧化酶影響,采用RAPD技術(shù)分析土壤微生物群落。結(jié)果表明,低濃度(25 mg·kg-1)阿特拉津?qū)谕岭迕富钚杂写龠M作用,中、高濃度(50~125 mg·kg~(-1))阿特拉津?qū)谕岭迕富钚跃哂幸种谱饔们覞舛仍礁咭种圃矫黠@;阿特拉津抑制土壤轉(zhuǎn)化酶活性,培養(yǎng)結(jié)束時(35 d),抑制作用仍然存在;阿特拉津?qū)Χ喾友趸富钚员憩F(xiàn)為抑制-促進-恢復(fù)規(guī)律;阿特拉津輸入改變土壤微生物群落結(jié)構(gòu),濃度越高變化越明顯。
[Abstract]:The effects of atrazine on urease, invertase and polyphenol oxidase in black soil were studied by means of indoor culture. Soil microbial communities were analyzed by RAPD technique. The results showed that low concentration (25 mg kg-1) atrazin could promote urease activity in black soil, and high concentration (50 鈮，
