摘要
稻田水旱轮作研究表明 :轮作区田块在夏作成熟期的细菌数量均高于连作 ,真菌的数量轮作方式 3比连作稍小 ,放线菌的数量轮作方式 2比连作稍小。其它生理群细菌数量 ,轮作与连作的差别都较大 。
The results of experiment showed : the amount of bacteria in the fields of paddy-upland rotation was higher than that in the fields of barely-rice-rice at the mature stage of early rice;the number of Fungi in the fields of the third type of paddy-upland rotation was smaller than that in the fields of barely-rice-rice;the number of actinomyces in the fields of the second type of paddy-upland rotation was smaller than that in the fields of barely-rice-rice. Other kinds of physiological bacterium groups in the fields of paddy-upland rotation were different from those in the fields of barely-rice-rice. But the number of microorganisms in the fields of paddy-upland rotation was clearly bigger than that in the fields of barely-rice-rice.
