摘　　要：将淡紫拟青霉不同菌株稀释后处理土壤后播种黄瓜,研究不同生长天数的黄瓜苗根际土壤中菌株的生长情况,明确不同菌株在育苗基质中的动态变化,并筛选出适宜的土壤添加浓度。结果表明:不同淡紫拟青霉菌株的生长速度不同,且不同添加浓度菌株的生长趋势也不很一致,其中IPC-P菌株生长速度最快,菌落数明显多于其它2个菌株;IPC-P菌株添加到土壤中的适宜浓度为1×104个/mL;XCZ 1-3菌株添加到土壤中的适宜浓度为1×105个/mL;YES菌株添加到土壤中的适宜浓度为1×105个/mL。In this study,different strains of Paecilomyces lilacinus diluted soil,then sowing cucumber seed.Studied the dynamic changes of Paecilomyces lilacinus strain in the cucumbe rhizosphere soil of different days in order to filter out the appropriate concentration of different strains in the soil.The results showed that IPC-P strains were selected to the soil wa more appropriate for the concentration of 1×104 Unit/mL;XCZ 1-3 strain added to the soil was more appropriate for the concentration from 1×105 Unit/mL;YES strains added to soil more appropriate for the concentration of 1×106 Unit/mL.
