弱光短日照育雌花黄瓜在低强度光照(1~2万勒克斯)和短日照(每天见光6~8小时)相结合的条件下,可显著增加雌花数目,所以,冬季日光温室黄瓜秆细叶小,是促进雌花发生发育的环境,3、4月份瓜数明显减少,需采取相应措施:①不再补充光照强度和延长光照时间;②实行变温与见干见湿管理,使其一边生瓜一边长瓜;③早揭晚盖和迟揭早盖草苫交替,使营养生长和生殖生长相 Under low light intensity (1 ~ 2 million lux) and short sunlight (6 ~ 8 hours per day), the female flower cucumber could significantly increase the number of female flowers. Therefore, the cucumber stalks in the greenhouse Ye Xiao, is to promote the development of female flowers in the environment, March and April significantly reduced the number of melons, the need to take appropriate measures: ① no longer add light intensity and extend the light time; ② variable temperature and see dry see the wet management, Melon side of the long melon; ③ early exposure late cover and late exposing the early cover Cairn alternate, so vegetative and reproductive growth phase
