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

硫磷長期污染對土壤微生物的影響，實驗表明：土壤細菌、放線菌、真菌總的數量影響不大；自生固氮菌和反硝化細菌數量減少；氨化細菌、亞硝化細菌、硝化細菌的數量在污染土壤中卻有所增加；與對照土壤相比，污染土壤呼吸作用下降了29 . 93 ；氨化作用和硝化作用強度得到增強。
