1980年和1981年,我县后季稻由于低温冷害大幅度减产,茬口晚的受害更重。为了改变这种局面,合理分配三熟作物的大田生育期,延长后季稻大田生育期,急需培育一个稳产高产的早稻早熟品种。青浦县农科所选育的“繁一”是比较理想的新品系。82年,经扩大试种,已取得较好收成。如徐泾公社联民五队,“繁一”占早稻面积60％以上,平均亩产达到839.6斤,收割后栽插的后季稻在8月2日就完成了任务。
In 1980 and 1981, the post-season rice crop in our county was greatly reduced due to chilling injury, and the later-crop injuries were heavier. In order to change this situation, it is urgent to cultivate a precocious early-maturing rice variety with high and stable yield in order to rationally allocate the growth period of three crops to the field and extend the growth period of the latter. Qingpu County agricultural selected breeding “a” is the ideal new line. 82 years, after expanding trial planting, has achieved better harvest. Such as the Xujing commune Alliance five teams, “a” accounted for more than 60% of the area of early rice, the average yield per mu reached 839.6 kg, after harvest after planting season rice on August 2 to complete the task.
