摘　　要：对5个大葱品种小拱棚越冬栽培的生长动态、营养品质及主要商品性状进行了比较试验。结果表明,越冬过程中大葱生长缓慢,章丘大葱甚至表现出负增长;不同大葱品种的冬性差异显著,收获时春味未发生抽薹,而田喜和章丘大葱的抽薹率分别达到42.6%和81.0%;各品种的经济产量以元藏和春味最高,均达3 500kg.(667 m2)-1以上,较章丘大葱增产540%以上。综合考虑大葱各品种的产量及主要商品性状,春味和元藏较适于冬季小拱棚栽培。The arcticle studied the effect of different Welsh onion varieties grown in low tunnel in winter. Results indi- cated that Welsh onion grew slowly in winter,Zhangqiudacong had even displayed negative growth. Wintemess of different varieties had significant differences. Bolting of Chunwei had not taken place until harvesting, and the bolting rates of Tianxi and Zhangqiudacong had reached 42.6 % and 81.0 % respectively. The yield of Yuanzang and Chunwei reached 52.5 t · hm^-2, which was 540 % higher than Zhangqiudacong. Therefore, Chunwei and Yuanzang were suitable for cultivation in low tunnel over winter season.
