摘　　要：在秋黄瓜的不同生育期,对植株根系分别进行了不同的输气处理.通过盆栽试验,对其根部性状,茎直径,植株鲜重和干重,花、果实产量等指标的研究结果表明:灌溉后每天向植株根系实施输气灌溉有利于秋黄瓜植株的生长,可提高雌花与雄花的比例和座果率及产量;每天1次向秋黄瓜植株根系输入空气10 min(约为80 L/(株·d)),保证适量的空气供应是最佳的处理.During the different growth stages of the autumn cucumber, different input gas rates are applied into plant roots. At the same time, root traits, stem diameter, fresh weight, dry weight, flowers, yields and some other factors of the autumn cucumber are measured through pot experiments. The results show that, inputting air to the plant roots everyday after irrigation which is referred to as gas irrigation helps the growth of the autumn cucumber plant and increase the ratio of female to male flowers, fruit set and yields. On the whole, it can achieve the best results to input air for about 10 min （about 80 L/（strain · d） ） to the root systems of cucumber autumn once a day.
