土壤微生物在成土过程及土壤肥力中的作用早已肯定,土壤中微生物学过程的分析研究,在旱地方面已累积很多资料。但是,水田微生物学的研究一直还很少,在我国,水稻是主要粮食作物之一,水田占耕地面积很大,今后还得进一步增加。根据农业发展纲要(修正草案),从1956年起,在12年内水稻种植面积增加二亿伍仟万亩,所以,水田微生物学的研究,对提高水田肥力的农业技术措施和增加我国粮食产量都具有特别重大的意义。
The role of soil microorganisms in the process of soil formation and soil fertility has long been confirmed. The analysis of microbiological processes in soils has accumulated a great deal of information in drylands. However, the research of paddy field microbiology has been still very few. In our country, paddy is one of the main food crops. The paddy field accounts for a large area of arable land and has to be further increased in the future. According to the Outline for Agricultural Development (Draft Amendment), from 1956 onwards, the area under rice cultivation will increase by 200 million or 60 million mu within 12 years. Therefore, the research on paddy field microbiology, the agricultural technical measures to increase the fertility of paddy fields, and the increase of both grain output in China Has a special significance.
