摘　　要：为研究不同播期和定植前植株大小对洋葱抽薹率及产量的影响,以自交多年的黄皮1号洋葱为试材,试验设置9月1日、6日、12日、18日4个播种时期及标准苗(假茎粗4~9 mm)、剥开鳞茎(假茎粗7~9 mm)、不剥鳞茎(假茎粗9~15 mm)3个植株大小,分别测定各处理抽薹率和产量指标。结果表明,9月1日播种的洋葱苗抽薹率最高,为47.03%;9月12日、18日播种的洋葱苗抽薹率较低,分别为4.17%和0。不剥鳞茎的处理抽薹率最高,为41.40%;标准苗的抽薹率最低,为8.07%。12日播种的洋葱苗产量较高,为86292.0 kg/hm^2,植株假茎粗为标准(4~9 mm)的产量最高,为84103.5 kg/hm^2。综合考虑,选在9月6—12日播种、洋葱苗假茎粗4~9 mm时定植,可降低洋葱抽薹率,提高后期产量。To investigate the impacts of different sowing time and plant size before planting on onion bolting rate and yield,Huangpi 1,which has beed self cured for many years,was used as research materials.The experiment was conducted with four sowing time(September 1,September 6,September 12,September 18)and three plant sizes[standard seedling(diameter 4-9 mm),bulb with peeling off(diameter 7-9 mm),bulb without peeling off(diameter 9-15 mm)],the bolting rate and yield were tested respectively.The results showed that the bolting rate was the highest sowing on September 1(47.03%),the bolting rate was lower sowing on September 12 and 18(4.17%and 0).The bolting rate of bulb without peeling off was the highest(41.40%),and lowest for standard seedling(8.07%).The yield was the highest sowing on September 12(86292.0 kg/hm^2),and the yield of standard seedling was the highest(84103.5 kg/hm^2).Comprehensive consideration,the bolting rate of onion could be reduced and the later yield could increase by sowing on September 6-12 and selecting standard seedling diameter(4-9 mm).
