水稻直播能提早季节、调节劳动力、省工、省秧地。近年来,杂交稻推广很快,为了观察把杂交稻和撒播结合起来后所表现的特点及在发挥杂种一代优势上的意义,我所从1980年开始,连续4年进行了杂交水稻撒播。其中3造大田撒播产量与大秧移植产量相近或稍高。1981年晚造“威优3号”撒播5.97亩,平均亩产988斤,是该造全所大田最高产的田块。1983年早造,“汕优2号”撒播11.25亩,平均亩产
Rice live earlier season, regulating the workforce, labor, provincial seedlings. In recent years, the promotion of hybrid rice is very fast. In order to observe the characteristics of combining hybrid rice with sowing and its significance in developing the advantages of hybrid generation, we have been carrying out hybrid rice sowing for four consecutive years since 1980. Among them, the output of 3-made field planting was similar or slightly higher than that of the large-seedling transplantation. The evening of 1981 made “Granville 3” sowing 5.97 acres, an average yield of 988 catties, is the most productive field in the whole made the field. As early as 1983, “Shanyou 2” sowed 11.25 acres, the average yield
