自1981年应用白僵菌油剂超低容量防治松毛虫试验成功后,在全省范围内推广应用白僵菌油剂、乳剂防治松毛虫,高含量孢子粉的用量增加了。为了探索贮存商含量孢子粉的方法,近几年来,我们分别做了低含水率低温贮存、同含水率不同温度、同温度不同含水率等三种不同的贮存方法试验,本次主要是进行不同包装材料贮存试验,以掌握白僵菌孢子粉的有效贮存方法。一、材料和方法(一)试验材料白僵菌孢子粉由高州县微生物厂提供,1983年11月生产,含孢量1,587亿/g,活孢率87％,含水率13.5%。(二)试验方法 1983年11月25日将上述孢子粉装进盛有氯化钙的干燥器内,至1984年5月3日取出(在室温下进行),测得活孢率为80％,含水率为4.3％。将这些孢
Since the application of Beauveria bassiana oil in 1981, the ultra-low-capacity control of pine caterpillars after the successful promotion of the application of Beauveria bassiana oil emulsion in the province, the prevention and control of pine caterpillars, high levels of spore powder increased. In order to explore the method of storing content of spore powder, in recent years, we have done three different storage methods, such as low water content, low temperature storage, different water content and different water content at the same temperature, Packaging material storage test to grasp the effective storage method of Beauveria bassiana spore powder. Materials and methods (a) Test materials Beauveria bassiana spore powder provided by Gaozhou microbial plant, produced in November 1983, the spore content of 158.7 billion / g, live spores 87% moisture content of 13.5%. (Two) test method November 25, 1983 will spore powder into the calcium chloride filled desiccator, to May 3, 1984 removed (at room temperature), measured viable rate of 80% , Moisture content of 4.3%. Put these spores
