摘  要：
为了筛选出冀西北坝上地区大葱适宜的定植密度,研究了不同定植密度对大葱植株性状、抗病性、产量和营养品质方面的影响。结果表明,285 855株/hm2的定植密度(株行距7cm×50cm)处理植株鲜质量和干质量分别为356.1、24.2g,显著高于其他处理;抽薹率最低,仅为1.0%;抗紫斑病和霜霉病,产量最高(101 890.95kg/hm2),较250 125株/hm2和333 495株/hm2的定植密度分别增产43.5%和42.5%;营养品质好。因此,285 855株/hm2的定植密度适宜在冀西北坝上地区大面积推广。

摘  要：
A study on the planting density of welsh onion was condcuted in Bashang region in Northwest Hebei.A comprehensive evaluation on plant traits,including disease resistance,yield and nutritional quality,was carried out.The results showed that the density of 285 855 plants per ha was the best among all the planting density,with the dry weight and fresh weight of welsh onion plant being significantly higher than those with the other treatments.The treatment had lowest bolting rate of 1.0%,and showed resistance to purple spot and downy mildew,with yield increasing 43.5% and 42.5% compared to 250 125 plants per ha and 333 495 plants per ha,respectively.This density was suitable for recommendation in Bashang region in Northwest Hebei.
