再生稻是一种古老的双季稻的栽培形式,在第四世纪张湛著的《养生要求》中已有记载,其开始栽培的时间,当然更早一些。再生稻过去之所以不被重视,主要是产量低,一般亩产只有50—100公斤,蓄再生稻也是抱着“有就收,无就丢”的思想,所用的品种再生力一般都不强,耕作管理亦较粗放,所以长期以来对再生稻就很忽视。近年来,农村实行生产责任制后,农民有了生产的自主权,加上有了再生力强的品种(如盐选203),和比较系统的栽培技术,能够获得较高的产量,因而其栽培面积有所发展。 Ratoon rice is an ancient form of double cropping rice. It was documented in Zhang Zhan’s “Keeping Requirements” in the 4th century, and the time to begin cultivation was, of course, earlier. The reason why ratooning rice was not valued in the past is mainly due to its low yield and generally only 50-100 kilograms of per mu. Its regenerative rice is also held in a " , Tillage management is also more extensive, it has long neglected ratooning rice. In recent years, after the implementation of the production responsibility system in rural areas, farmers have the autonomy in production, coupled with the more regenerative varieties (such as salt selection 203), and more systematic cultivation techniques, which can achieve higher yields. Therefore, Cultivated area has been developed.
