前一部分工作,说明了稻田灌水前后各微生物羣变化的情况;从材料中可以看出,细菌数量在任何时期都较其他微生物为多,我们的资料,细菌约占微生物总数(细菌、真菌、放线菌)89—97%。因此,进一步研究在灌水前后不同时期的细菌区系,无疑地在理 The first part of the work described the changes in microbial populations before and after irrigation in paddy fields. It can be seen from the material that the number of bacteria is more than that of other microorganisms at any time. Our data, bacteria account for the total number of microorganisms (bacteria, fungi, Strains) 89-97%. Therefore, to further study before and after irrigation in different periods of bacterial flora, no doubt in science
