前言乙烯利(二氯乙基磷酸)在黄瓜上做为化学去雄剂,国内外已广泛地研究和应用。现已明确乙烯利对黄瓜的花原始体向雌性花转化有明显的效果。如何利用乙烯利对黄瓜的这一效能达到早熟丰产的目的,尚未见到这方面的报导。当前,在黄瓜栽培上存在着霜霉病的严重威胁。实践证明,现有抗霜霉病的黄瓜品种不早熟,早熟品种又不抗霜霉病。诚然,这种矛盾是可以通过栽培管理和药剂防治加以解决的,但是应用药剂防治和改进栽培措施来达到早熟、丰产、防病的目
Pretreatment ethephon (dichloroethyl phosphate) on cucumber as a chemical maletive, both at home and abroad have been widely studied and applied. It is clear that ethephon cucumber flower primordial female flower conversion has a significant effect. How to use this effect of ethylene on cucumber to achieve the purpose of early yield, yet to see this report. Currently, there is a serious threat of cucumber downy mildew cultivation. Practice has proved that the existing varieties of cucumber downy mildew precocity, precocious varieties not downy mildew. Admittedly, this contradiction can be solved through cultivation and management and chemical control, but the application of chemical control and improved cultivation measures to achieve early maturity, high yield and disease prevention
