杀虫菌土法产品的干燥处理,主要采用烘干和日光直接曝晒的方法。烘干需要大量燃料,效率慢;日光曝晒,由于阳光中紫外线的杀菌作用,使成品含菌数显著下降。为了解决这个问题,我们选用了一些常用而又经济的材料作为覆盖物,测定它们对紫外线的吸收效果,并从中选出吸收效果好的农用无色塑料薄膜,已在生产中推广应用。 Drying of insecticidal soil products, the main method of drying and direct sun exposure. Drying requires a lot of fuel, slow efficiency; sunlight exposure, due to the bactericidal effect of UV in the sun, so that the finished product significantly decreased the number of bacteria. In order to solve this problem, we choose some commonly used and economical materials as coverings, measure their absorption effect on UV light, and choose a good absorption of agricultural colorless plastic film, which has been widely used in production.
