黄瓜植株对水分反映比较敏感,根据这一特点,可从植株形态进行管理。但因冬季气温低,光照弱,应始终掌握不浇明水或少浇水,防止地温下降。要一看龙头:正常植株叶色从下到上由深到浅,龙头舒展肥壮,有两片以上未放展的幼叶拢包,颜色鲜绿,毛茸发达,各小叶生长均匀,叶柄与茎叶45度角,叶片平展。缺水时龙头瘦小而尖,已放展的叶片与龙头间距离近,叶色发黑
Cucumber plants are more sensitive to moisture, according to this feature, can be managed from the plant morphology. However, due to the low winter temperatures, weak light, should always grasp the water is not poured or less watering to prevent the temperature drop. To look at the leading: the normal plant leaf color from bottom to top from the light to the shallow, the leading stretch of fat, there are two or more young leaves not Shuanbao package, brightly colored, furry developed, the leaflets grow evenly, petiole and 45 degrees angle stems, leaves flat. Lack of water when the leading small thin tip, has been the development of the distance between the leaves and the faucet, leaf color black
