我们生产队在农业学大寨运动中,积极推广杂交水稻,大搞“三系”制种,获得好收成。一九七六年晚造搞制种田17亩,组合是二九南A×IR24,平均亩产124斤,其中4.17亩,平均亩产200.2斤。措施主要抓下几点: 三叉壮秧打基础“秧好一半禾”,水稻“三系”制种育好秧尤为重要。因为制种田父母本均为单株种植,主要是依靠分蘖成穗来夺取高产,且二九南A生育期又短,培育“三叉秧”,便为制种田父母本早分蘖、早够苗创造了良好的条件。在育秧中我们的做法是:首先选择比
In the Dazhai Campaign for Agriculture, our production team actively promoted hybrid rice and vigorously pursued the “three lines” seed production and achieved good harvests. In late 1976, a total of 17 mu of land was planted for farming. The combination was 29 nam A × IR24 with an average mu yield of 124 kg, of which 4.17 mu and an average yield of 200.2 kg. The main measures to grasp the following points: Fork strong seedling baskets “good seedling half Wo”, rice “three lines” system is particularly important seedling cultivation. Because the system of farming parents are single plantation, mainly rely on tillering spike to seize high yield, and two nine South A growth period is short, cultivate the “Trident seedling”, then the system of farming parents this morning tillering, seedling early enough to create Good condition. Our approach in growing seedlings is: first select the ratio
