俗话说得好,“庄稼一支花,全靠粪当家”。意思是说,只要有充足粪肥,就能保证庄稼稳产高产。但是,你可能不知道,粪肥里所含有的营养元素不经发酵分解,庄稼是不能直接吸收的。需要聘请技术高超的“厨师”进行烹调,然后再送到庄稼的嘴边。为庄稼烹调佳肴的“厨师”,常年居住在土壤里,他们是肉眼看不到的微小生物——细菌、真菌和放线菌。有人测算,三十多亿的细菌个体加在一起,也只有芝麻粒那么大。别看他们如此渺小,可是数量极多,能量很大,每公斤土壤里居住着几千亿甚至上万亿这样的小生物。从地面到几公尺深的土层,都是他们活动的场所。在微观世界里,他们各有分工,每时每刻都在紧张而又有秩序地工作着。
As the saying goes, “a flower crop, thanks to manure”. Means that as long as there is sufficient manure, we can ensure a stable and high yield crops. However, you may not know that nutrients contained in manure are not decomposed by fermentation and crops can not be directly absorbed. Need to hire a skilled “chef” for cooking, and then sent to the mouth of the crop. Cooks who cook food for the crops live in the soil all year round, tiny organisms that are invisible to the naked eye - bacteria, fungi, and actinomycetes. It is estimated that more than three billion bacteria together, only sesame seeds so large. Do not look at them so small, but a very large number, great energy, each kilogram of soil living in hundreds of billions or even trillions of such small creatures. From the ground to a few meters deep soil, is their place of activity. In the microscopic world, they all have their own division of labor and work in an intense and orderly manner all the time.
