从1967年以来,我们试验改早稻——二季晚稻——绿肥为早稻——秋大豆——小麦(或油菜)一年三熟制的耕作制度。在党组织的领导下,组成三结合科学实验小组,开展群众性科学实验活动,取得了可喜成果。实践证明,实行稻——豆——麦(油)一年三热制轮作换茬,具有增加油料,提供饼肥,培肥土壤,缓和“双抢”用水、用肥及劳力、畜力的矛盾等优点。1974—1975年度,稻——豆——麦三熟全年亩产折合稻谷1,697斤,比稻——稻——肥一年二熟 Since 1967, we have experimented on the farming system of early rice - second season late rice - green manure for early rice - autumn soybean - wheat (or rape) one year. Under the leadership of the party organizations, the three-pronged scientific experiment group has been formed to carry out mass scientific experiment activities and gratifying achievements have been made. Practice has proved that the implementation of rice - beans - wheat (oil) a year three hot rotation cropping change, with increased fuel, provide cake fertilizer, fertilize the soil, ease the “double grab” water, fertilizer and labor, animal power and other conflicts . In 1974-1975, the annual output of rice-beans-wheat-three-millet was equivalent to 1,697 pounds of rice per mu, more than that of rice-rice-fertilizer
