湘、鄂、赣三省五十年代初的稻田耕作制度是以一年一熟制为主,一季稻占稻田面积的85%以上,冬季多为冬炕或冬泡,只有部分种冬作物。六十年代中期始,推广一季稻改双季稻,复种指数不断提高,双季稻面积逐年扩大,与此配套的紫云英绿肥也很快发展起来。七十年代“绿肥—双季稻”已成为稻田复种制度的主体,到1977年,三省双季稻面积达到最高峰,占水田总面积的60%以上,“绿肥—双季稻”又占双季稻面积的70%以上。这种改革措施对三省粮食增产,尤其是水稻增产,起了重要作用。

The farming systems in the early 1950s in Hunan, Hubei and Jiangxi Provinces were dominated by one-year-old cropping system. The first-season rice accounted for more than 85% of the total paddy field area. Most of the winter-season winter paddy fields were winter kang or winter blisters. Only some of the winter crops were planted. The beginning of the mid-1960s, the promotion of a quarter of rice to double cropping rice, crop index continued to increase, double cropping rice area expanded year by year, with this supporting Ziyunying green manure also quickly developed. Seventies “green manure - double cropping rice” has become the main body of cropping system, double cropping rice in three provinces reached the peak in 1977, accounting for more than 60% of the total paddy field, “green manure - double cropping rice” More than 70% of rice area. This reform measure has played an important role in boosting grain output in the three provinces, especially rice.
