摘　　要：2009-2012年对大葱的栽培技术进行了研究。结果显示,延长营养生长期可明显提高农艺性状;阿维毒不适宜作为大葱的除草剂,而播前用二甲戊灵处理土壤,可明显抑制杂草生长;施用甲K素后,大葱抗逆性增强,单株重、假茎长等农艺性状优于对照;施用P、K肥的增产效果最明显;随着密度增加,单产增高,但单株重下降。Studies on welsh onion sowed in autumn from 2009 to 2012.The results showed that agronomic traits of welsh onion were improved by prolonging vegetative period.Herbicide Avi poison was not suitable for cleaning weed in welsh onion field.Treatment by pendimethalin before sowing can inhibit the growth of weeds.Resistance was improved by potash fertilizer,as well as single plant weight,pseudostems length,etc.Both phosphate and potash fertilizer increased yield obviously.With the increasing density,yield per mu increased and single plant weight dropped.
