1976年我们种植了15亩再生稻试验田,品种“广二矮5711”,早造平均亩产838斤,二熟(再生稻)虽然在花期遭到特早强寒露风袭击,但仍然比双季晚稻增产,平均亩产510.5斤,并提早22天收割,取得了冬麦生产主动权。实践证明,再生稻是耕作制改革中一种既有利于争取季节,实现三熟高产,又能节约劳力和成本的优良耕作法。为了进一步摸清水稻再生高产的规律,我们对再生稻的一些生育特点进行了初步观察,并联系有关栽培技术进行了探讨,现分述于下。
In 1976, we planted 15 mu of regenerative rice trial field. The variety “Guang Er short 5711” made an average of 838 kg per mu. As for the second crop (ratoon rice) Late rice yield, the average yield 510.5 kg, and harvest 22 days earlier, made winter wheat production initiative. Practice has proved that ratooning rice is a tillage system reform is conducive to fighting for the season to achieve high yield three crops, but also save labor and cost of good cultivation practices. In order to further find out the law of high yield of rice, we conducted preliminary observations on some reproductive characteristics of ratoon rice and discussed the related cultivation techniques.
