我区大白菜栽培面积逐年增加,据银川市1965年统计,约达到秋荣栽培面积的三分之一以上。因此,需种量很大。过去灌区群众大都采用成株(母根)采种法留种,由于种株在聍藏期间及栽植后容易腐烂死亡,采种此较困难,因此采种量少,种价昂贵,数量也不能满足生产需重。每年要从外地调入大量白菜子种。因此,调查和研究大白菜的成株采种技术,提高种子的产量和质量,对发展我区大白菜的生产具有重要意义。
I cabbage cultivation area increased year by year, according to statistics in 1965 in Yinchuan City, about autumn cultivation area of more than one-third. Therefore, the need for a great amount. In the past, most of the people in the irrigation areas used the adult (mother root) seed-collecting method to keep seeds. Since the seedlings were easily perishable during the Tibetan storage period and after planting, it was more difficult to seed the seeds. Therefore, the seed collection was less and the price was rather expensive. weight. Every year from the field transferred a large number of cabbage seeds. Therefore, it is of great significance to investigate and study the technology of adult plant seed collection and improve the yield and quality of Chinese cabbage.
