再生稻又名“秧荪谷”,是利用早、中稻品种的再生力而获得增产的一项栽培措施。它具有省工、省种、省水、早热、管理简易的特点。1974—1976年,我所开展了再生稻品种选育和栽培技术的研究,取得了再生稻亩产400—700斤的产量。我省部分社队的多点试验也取得较好的成绩。如合川县沙溪公社堰口一队,两年用泸双1011作再生稻,两季亩产980—1,104斤,再生稻亩产200—300斤。1976年垫江县普顺公社和平大队试验,两季亩产1,063斤,再生稻亩产271.6斤(1975年再生稻亩产高达437.5斤)。

Regeneration rice, also known as “seedling sunflower valley”, is a cultivation measure that can be used to increase yield by utilizing the regenerative power of early and middle rice varieties. It has a provincial labor, provincial species, water, early heat, simple management features. From 1974 to 1976, I conducted research on the breeding and cultivation of ratoon rice varieties and obtained 400-700 kg per mu of ratoon rice. Some of the teams and teams in our province also achieved better results in the multi-point experiment. For example, a team from Weirkou, Shaxi Commune, Hechuan County, used Lunshan 1011 as ratooning rice for two years, with 980-1,104 jin per mu in two quarters and 200-300 jin per mu for regenerated rice. In 1976 Dianshun County Puxun Commune peace battalion test, two-season mu produce 1,063 catties, 271.6 kilos of re-produced rice per mu (regenerative rice yield in 1975 up to 437.5 pounds).
