作者从1962—1963年洋葱播种期的試驗中看出,播种越早,先期抽苔率越高,1962年9月5日播种的黄皮洋葱和紅皮洋葱抽苔率高达23%和16.7%,9月15日播种的抽苔率分别下降到6%和1.9%,9月25日播种的沒有先期抽苔現象。抽苔后,养份都消耗到开花結实上,向鳞茎里积累的养份减少,影响到产量。例如,黄皮洋葱未抽苔的鳞茎鮮重为一百三十五克,而抽苔的只有五十八克,为未抽苔的43%;

The author from the 1962-1963 onion sowing period of the experiment found that the sowing earlier, the higher the rate of early moss, sown September 5, 1962 yellow onion and red onion onion moss rate as high as 23% and 16.7% , The moss rate sowed on September 15 dropped to 6% and 1.9% respectively, and there was no prior bolting on September 25. After bolting, nutrients are consumed to flowering firm, reduce the accumulation of nutrients to the bulb, affecting the yield. For example, the bollworm bulb has a fresh weight of 135 grams, while the bolting amount is only 58 grams and 43% of the bolting amount.
