早春黄瓜定植初期常发生“花打顶”现象,表现为生长点形成雌雄间杂花簇,幼苗生长缓慢,茎矮小,节间短,各节集中聚成一团。由于形成“花打顶”的原因不同,应分析原因,区别对待。 一、定植幼苗已呈现有“花打顶”或“小老苗”。应从培育壮苗入手,加强苗期管理,定植时剔除“小老苗”及素质不高的苗。 二、早春黄瓜定植缓苗后,为提高地温及控制促长,采用控制浇水,因而造成“花打顶”。应立即浇水.并保持适宜黄瓜生长的温度,可促使萌发心叶,逐渐转为正常生长。
Early spring cucumber planting often occur in the early “topped” phenomenon, the performance of the growing point to form the male and female miscellaneous flowers clusters, slow growth of seedlings, stalks short, short internodes, each section concentrated together into a ball. Due to the formation of “flower top” for different reasons, should analyze the reasons for discrimination. First, seedlings have been planted with a “top” or “small seedlings.” Should start nurturing strong seedlings, strengthening seedling management, when planting remove “small seedlings” and the quality of seedlings. Second, early spring cucumber planting Huanmiao, in order to improve the ground temperature and control of growth, the use of controlled watering, resulting in “topped.” Watering should be immediately.And to maintain the appropriate temperature for the growth of cucumber, can promote the germination of heart leaves, and gradually turned into normal growth.
