摘要： 在自然农法条件下，对稻田连续9年施用有益微生物群（EM） 的累积栽培效果进行了研究。连续施用EM 使土壤的养分状况发生了明显的改变，使水稻抽穗期推迟，花期延长，叶色加深。 EM 的应用还能有效地改善产量结构、提高产量，而且应用年限越长，效果越明显，并且有助于改善稻米品质、减少稻米中钾和镁的含量、增加直链淀粉含量和食味评价值，口感较好。EM 的应用在一定程度上可以抑制杂草的发生和生长

Abstract: The accumulated effects of effective microorganisms(EM) continuous application for 9 years in paddy field were studied in nature farming.Under continual application of EM,the soil nutrients changed greatly,and rice growth was also affected,such as delay in heading,prolongation of flowering period and deepening of leaf color.EM application significanly increased rice yield and the effect became greater with the year increasing.In addition,EM application could improve rice taste quality,decrease K and Mg contents,increase amylose content and taste value of rice.Moreover,EM application could control weed germination and growth to some extent.
