近年来,我区油菜面积不断扩大,单产逐年提高,高产田块也大批涌现,1978年一块地面积1.1亩,单产519.9斤;1979年十九块地合面积40.26亩,最高单产534斤;1980年二十八块地合面积77.04亩,最高单产560.9斤。为了认真探索油菜高产生育规律,于1980年秋播时,组织并进行了高产栽培协作攻关试验,试验获得了初步成果。1981年全区出现500斤以上的高产田36块,计164亩,最高单产达600斤以上。
In recent years, the area of rapeseed in my area has been constantly expanding. The yield per unit has been increasing year by year. High-yielding plots have also emerged in large numbers in 1978, covering an area of 1.1 mu and a yield of 519.9 kg. In 1979, 19 plots reached 40.26 mu and the highest yield was 534 kg. In twenty-eight area of 77.04 acres, the highest yield 560.9 pounds. In order to conscientiously explore the law of high yield and rapeseed fertility, in the fall of 1980, we organized and carried out high yielding cultivation collaborative research, and obtained preliminary results. In 1981, there appeared 36 high-yield fields of more than 500 kilograms, accounting for 164 mu in total, and the highest yield reached 600 kilograms or more.
