一些黄瓜品种于幼苗第6节摘心,第一次侧蔓和次生侧蔓在第2叶摘心,有促进其基部叶腋花芽雌蕊发育、改变花芽性别分化趋向的效果。这既能促使初发生的花芽雌蕊发育,形成雌花;又能使向雄性趋向发育花芽中的雌蕊发育形成两性花;有时也能在卷须上着生雌花;使花芽在高温长日照条件下,向雌性转化;还可促使苗期因喷过“乙烯利”而于植株基部形成的“空节”变成雌花节。矮化栽培一定要适时摘心,选择适于摘心的品种,苗期喷用150～200ppm的“乙烯利”,每亩栽苗5000株以上,施足肥料,合理灌水,及早防病,这样可比搭架黄瓜提早上市5～10天,亩产20000斤左右,采收期100天以上。
Some cucumber varieties in the seedling section 6 topping, the first side vine and the secondary side vine in the second leaf topping, there is to promote its base axillary flower bud pistil development, changing the gender bud differentiation trend. This can not only promote the early occurrence of the flower bud pistil development, the formation of female flowers; but also to the male tend to develop pistil development of flower buds to form bisexual flowers; sometimes on the tendrils with female flowers; the flower buds under high temperature and long daylight conditions, to Female transformation; but also to promote the seedling due to spraying “ethephon” at the base of the plant formed “empty section” into a female flower section. Dwarfing cultivation must be timely topping, select the species suitable for topping, seed spraying with 150 ~ 200ppm “ethephon”, planted more than 5000 acres per mu, adequate fertilizer, reasonable irrigation, early prevention, so comparable to take Rack cucumber listed 5 to 10 days earlier, about 20000 pounds per mu, harvest more than 100 days.
