摘要
采用稀释平板计数法,研究了不同药剂对马铃薯田土壤微生物数量的影响。结果表明,6种药剂施入马铃薯土壤中使微生物的数量发生了变化,4次测定结果显示,以施入微生物制剂(木酶制剂)的土壤中细菌、放线菌和真菌数量增加值最大,表现最好,与对照药剂(50%多菌灵)和空白对照相比,细菌数量分别增加了79.06%、106.07%,放线菌数量分别增加114.24%、101.08%,真菌数量分别增加47.47%、36.26%。木霉制剂处理能促进土壤有益微生物的繁殖,改善土壤微生态环境,抑制有害真菌的繁殖,增强马铃薯的抗逆能力。
The effect of different pesticides on microbial quantity of potato soil was studied by dilution-plate method.The results showed that the six kinds of pesticides applied to potato soil changed the number of microorganisms.The added quantities of bacteria,actinomycetes and fungi in soil treated by microbial agents（trichoderma preparation） were the largest,and the performance was the best.Compared to the control pesticide（50% carbendazim） and CK,the number of bacteria increased by 79.06% and 106.07%,the number of actinomycetes increased by 114.24% and 101.08%,and the number of fungi increased by 47.47% and 36.26%,respectively.The trichoderma preparation can promote the breeding of beneficial soil microorganisms,inhibit the propagation of harmful fungi and enhance the resilience of potato plants.
