微生物农药(如“九二○”、杀螟杆菌、“5406”等)的土法生产,在夏天由于气温高,降温比较困难,霉雨季节,由于潮湿、温度高,容易受杂菌污染,因此,产品质量明显下降,甚至无法生产。采用瓶子代替大床发酵生产,可以解决以上问题。但由于瓶子容量很小,就需要大量的瓶子,其操作也较麻烦,生产过程很慢,产量不高。 Microbial pesticides (such as “920”, Chibi, “5406”, etc.) indigenous production, due to high temperatures in the summer, cooling more difficult, due to wet weather, humidity, susceptible to bacterial contamination, As a result, the quality of the product has dropped significantly, and can not even be produced. The use of bottles instead of fermentation bed production, you can solve the above problems. However, due to the small capacity of the bottle, a large number of bottles are needed and the operation is troublesome. The production process is slow and the yield is not high.
