塑料大棚栽培黄瓜,由于管理不当,化瓜现象十分严重,有时高达50%,直接影响着黄瓜的产量和产值。为此笔者进行了积极的探索,并认为造成黄瓜化瓜与以下因素有关:1.高温引起化瓜白天温度高于32℃,夜间高于18℃,光合作用受阻,呼吸消耗骤增,造成营养不良而化瓜。同时高温造成雌花不能正常发育,出现畸形瓜。在栽培上应加强放风管理,白天在棚温高达25℃
Cucumber plastic greenhouse cultivation, due to improper management, melon phenomenon is very serious, sometimes up to 50%, directly affects the yield and output of cucumber. To this end the author conducted a positive exploration and believes that the cucumber melon with the following factors: 1. High temperature caused melon during the day temperature is higher than 32 ℃, night is higher than 18 ℃, photosynthesis blocked, respiratory consumption surge, resulting in nutrition Bad and melon. At the same time caused by high temperature can not be normal female flower development, there deformity melon. Cultivation should be strengthened in the ventilation management, daytime shed temperature up to 25 ℃
