为了保证农业丰产,使用666防治地下害虫是通常采用的措施之一。大家都知道,土壤微生物的活动是与农业增产密切相关的。那么666是否对土壤微生物的活动有影响呢?为了了解这个问题,中国科学院北京微生物研究室进行了一些试验。现将初步观察的结果,报导于后。 试验是从三方面进行的:(i)666对土壤微生物的生化活性的影响;(ii)666对土壤微生物 In order to ensure high agricultural productivity, the use of 666 to control underground pests is one of the commonly used measures. As we all know, the activity of soil microorganisms is closely related to the increase of agricultural output. So 666 whether the impact on soil microbial activity? In order to understand this problem, the Chinese Academy of Sciences Beijing Microbiology Laboratory conducted a number of experiments. Now the results of the initial observation, reported later. The experiment was conducted in three aspects: (i) the effect of 666 on the biochemical activity of soil microorganisms; (ii) 666 soil microbial
