我们从1970年起,进行放养红萍作晚稻秧田底肥的试验,到1973年,全公社晚稻秧田养萍面积由1970年的1.5亩扩大到700多亩,占二晚秧田面积的70％。晚稻秧田养萍,不但解决了二晚秧田的底肥,同时缓和了二晚秧田与“后三田”争肥的矛盾,对“后三田”高产和晚稻大面积增产都有一定的促进作用。 Since 1970, we conducted the experiment of stocking red aspen for the base fertilizer of late-season rice seedlings. By 1973, the entire commune’s rice-growing area for late-season rice seedlings expanded from 1.5 mu in 1970 to 700 mu, accounting for 70% of the area of ​​the second-late seedling. Late rice seedling Yangping, not only solved the two night seedling base fertilizer, and alleviate the two night seedling and “after the three fields” fight the conflict, the “latter three fields” large-scale production and late rice have a certain role in promoting.
