当前,有些地方反映:用高温(50—70℃)生产“5406”,生长快,质量好。为进一步了解温度对生产“5406”菌肥的影响,我所进行了初步试验,结果如下: 从上表可看出: 1.不灭菌或灭菌不彻底的饼土,无论是否接菌,在高温下(50℃以上),长出的白色孢子,经显微镜检查,不是“5406”菌,而是小单孢菌。小单孢菌属高温型腐生放线菌,在土壤和空气中很多。所以,在堆制饼土不灭菌或母剂灭菌不彻底的情况下,高温生产很易长出小单孢菌。
At present, some places reflect: high temperature (50-70 ℃) to produce “5406”, grow fast, good quality. To further understand the temperature on the production of “5406” fertilizer, I conducted a preliminary test, the results are as follows: As can be seen from the table: 1. not sterilization or incomplete sterilization of the cake, whether or not inoculation, At high temperatures (above 50 ° C), white spores grow, microscopically, not “5406” bacteria but Micromonospora. Micromonospora Thermophilic saprophytic actinomycetes, many in the soil and air. Therefore, in the piled cake soil is not sterile or incomplete disinfection mother case, the high temperature production is easy to grow Microtus.
