摘　　要：2009-2013年对春播大葱的栽培技术进行了研究.结果显示：春播大葱宜采用早春大棚播种;在适宜的定植期,越早定植越有利于大葱营养物质的积累,增加单株重、假茎长及产量;适宜的密度为17000～18500株/667m2;繁种以11月中到12月中温室播种,次年春季定植,其抽薹率及种子产量为最优.Welsh onion sowed in spring was studied from 2009 to 2013.The results showed that this welsh onion should be sowed in greenhouse in early spring.The earlier it planted in field,the more nutrient accumulated in plant.And the single plant weight, pseudo stem length and yield increased higher.The proper density was 17000-15500 plants per 667m2.The better way for seed reproduction was that sowed in greenhouse from the middle of September to the middle of November,planted in next spring,and bolting rate and seed yield were optimal.
