白菜型春性小油菜,是我场栽培的主要作物之一,常年播种面积10万余亩,占全场总耕地面积的60％左右。前几年,单产只在150斤左右。1976年以来,我们对小油菜高产栽培技术进行了专题研究,初步摸索到它的高产规律。1978年在战胜风、旱、雹等自然灾害后,本所及一、二农科站在15亩以上的面积上,分别取得亩产417.94斤、435.63斤, Spring cabbage-type rapeseed is one of the main crops cultivated in our field. The perennial planting area is more than 100,000 mu, accounting for about 60% of the total cultivated land. A few years ago, yields only about 150 pounds. Since 1976, we conducted a special study on high yielding cultivation techniques of rapeseed, and initially found its law of high yield. In 1978, after defeating wind, drought and hail and other natural disasters, the Institute and the Agricultural Science and Technology Station of No. 1 and No. 2 took 417.94 kg of mu and 435.63 kg of mu per mu in an area of ​​more than 15 mu,
