我所从1973年开始进行再生稻的试验研究工作。几年来,我们进行了再生栽培的品种观察试验,头造收割高度、收割期、播植方式与再生关系的试验,以及再生栽培的肥水管理试验等。从试验结果看,再生稻亩产一般都达到或接近同品种、同地力、同肥料水平的插植晚稻产量。1973年,试种品种为“广二矮5711”,面积0.36亩,头造亩产636.4斤, Since 1973, we have conducted experimental research on ratoon rice. Over the past few years, we conducted varieties of renewable cultivation observation test, head of the harvest height, harvest time, the relationship between planting methods and regeneration test, and fertilizer cultivation and management of renewable cultivation experiments. From the test results, the average yield per mu of regenerated rice is up to or close to that of the same variety, with the same fertility, and the same level of fertilizer. In 1973, the trial variety was “Guang Er short 5711” with an area of ​​0.36 mu and a head of mu produce 636.4 kg,
