| 7. | 1 . ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study . little difference in total counts of bacteria , actinomycetes and fungi was observed between the contaminated and the non - contaminated soil . compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil
一、甲基对硫磷长期污染对土壤微生物的生态学效应研究了有机磷农药甲基对硫磷长期污染对土壤微生物的影响，实验表明：土壤细菌、放线菌、真菌总的数量影响不大；自生固氮菌和反硝化细菌数量减少；氨化细菌、亚硝化细菌、硝化细菌的数量在污染土壤中却有所增加；与对照土壤相比，污染土壤呼吸作用下降了29 . 93 ；氨化作用和硝化作用强度得到增强。 |
