(1)黄瓜幼苗生长到两片真叶时,喷浓度为200mg/kg的乙烯利溶液,隔1周再喷一次,可使黄瓜增产8.8％～13.5％。 (2)在黄瓜出苗后40～50天内,每天进行8小时左右的短日照处理可促进雌花分化,增加雌花数量,从而增加产量。 (3)黄瓜幼苗喷施0.2％红糖液,可使秧苗粗壮,心叶快长。结瓜期喷施0.75％～1％的红糖液,每天1次,可使瓜条直,产量高,口感好,并防治霜霉病。 (4)在黄瓜幼苗根部(不可太近以免烧根)或叶面撒施草木灰,10天左右撒1次,共撒4～5次,既防病虫害,又能提高品质,一般增产10％以上。 (1) Cucumber seedlings grow to two true leaves, spray concentration of 200mg / kg of ethephon solution, spray once every other week, cucumber yield 8.8% ~ 13.5%. (2) Within 40-50 days after the emergence of cucumber, the short daylight treatment of about 8 hours per day can promote the differentiation of female flowers, increase the number of female flowers and increase the yield. (3) cucumber seedlings spraying 0.2% brown sugar solution, seedling sturdy, heart leaves grow fast. During the fruiting period, 0.75% ~ 1% of brown sugar solution is sprayed once a day, which can make the melon straight, high yield, good taste and prevent downy mildew. (4) Cucumber seedling roots (not too close to avoid burning roots) or foliar application of ash, about 10 days sprinkle a total of 4 to 5 times, both pest control, but also improve the quality of the general increase of more than 10% .
