互助县是青海省的主要油菜产区之一。近几年来,随着优良品种的推广和栽培措施的改进,互助县油菜生产发展比较迅速,每年种植面积在15万亩左右,其中约10万亩是白菜型小油菜。白菜型小油菜的平均单产在60公斤左右,增产潜力还很大,为了使互助县油菜生产再上一个新台阶,我们在更换油菜新品种的基础上,从1984年起对白菜型小油菜的丰产栽培模式进行了研究。1988—1989年我们通过学习外地经验,在过去大量单因子试验的基础上,应用系统工程理论和电子计算机的帮助,在本县脑山地区设置了“白菜
Huzhu County is one of the major rape producing areas in Qinghai Province. In recent years, along with the promotion of fine varieties and the improvement of cultivation measures, the rapeseed production in Huzhu County has developed rapidly. The annual acreage is about 150,000 mu, of which about 100,000 mu are cabbage rapeseed. Cabbage rapeseed average yield of about 60 kg, yield potential is still great, in order to Huzhu County rapeseed production to a new level, we have to replace the new varieties of rapeseed, from 1984 on cabbage rape High yield cultivation patterns were studied. From 1988 to 1989, based on a large number of single-factor experiments in the past and through the help of systems engineering theory and electronic computers, we learned "
