微生物农药的重大意义微生物是自然界中一类形体微小、结构简单的生物。微生物和其他生物一样,也有生长、发育、死亡等过程,都有繁殖后代的能力。但是,微生物对环境的适应能力特别强,而且它们的繁殖速度快得惊人,有些细菌在几十分钟内就可繁殖一代。因此可以进行人工培养和生产,使用其有利的一面为人类服务。微生物可分为四大类:第一是细菌,第二是放线菌,第三是真菌,第四是病毒。从对农作物的关系来说,真菌中有害
The great significance of microbial pesticides Microorganisms are a kind of small, simple organisms in nature. Like other organisms, microorganisms also have the ability to grow, develop, die and have their offsprings. However, microorganisms are particularly resilient to the environment and their breeding speed is staggering, with some bacteria multiplying in just a few minutes. It is therefore possible to cultivate and produce artificially, using its favorable side to serve humanity. Microbes can be divided into four categories: the first is bacteria, the second is actinomycetes, the third is fungi, the fourth is a virus. Fungus is harmful from the point of view of crops
