| 摘 要： | 本文通过对土壤呼吸强度，各微生物生理群的数理以及土壤酶活性的测定，研究了氯苯，对硝基酚对土壤生物活性的影响。实验表明氯苯，对硝基酚对土壤活性的影响是复杂的。氯苯在２００ｍｇ／ｋｇ以下对土壤呼吸强度，细菌放线菌及真菌的数量都有一定的刺激作用；而对氨化细菌硝化细菌以及反硝化细菌则表现出抑制作用；

| Abstract: | The effect of chlorobenzene and nitrophenol on soil biological activity was studied through analyzing soil respiration intensity, microbial numbers and soil enzyme activities. The results showed that the effect of chlorobenzene and nitrophenol on soil biological activity was complex. Chlorobenzene below 200mg/kg could stimulate soil respiration and total numbers of bacteria, actinomyces and fungi, but inhibit amoniafying bacteria, nitrifying bacteria and denitrifying bacteria. The chlorobenzene below 200mg/kg also stimulated the activities of urease and dehydrogenase but slightly inhibited the activity of sucrase. Nitrophenol below 200mg/kg inhibited the growth of almost all microbes and the activities of several enzyme. |
