在保护地黄瓜栽培中,温、光、肥、水、气条件是否适宜,从植株形态上可以直接表现出来。在生产实践中,我们常根据植株形态进行诊断,并及时采取相应的管理和防治措施,往往会获得立竿见影的效果。现将保护地黄瓜叶片不同形态产生的原因及应采取的防治措施介绍如下:1.叶片大而薄、呈圆形,叶缘缺刻浅,叶柄较长,叶柄与茎夹角小于45℃,叶片与叶柄夹角增大,并往往伴随雄花产生过多这主要是由于夜间温度偏高,光照不足,肥水过多而造成的。因此,应加强通风、透光,降低夜温、拉大昼夜 In protected cucumber cultivation, temperature, light, fertilizer, water, gas conditions are appropriate, from the plant morphology can be directly manifested. In production practice, we often diagnose according to plant morphology, and timely take the appropriate management and prevention measures, often get immediate results. The reasons for the different forms of cucumber leaves and the control measures should be introduced as follows: 1. The leaves are large and thin, round, lack of leaf margin shallow, long petiole, petiole and stem angle less than 45 ℃, leaves Increased angle with petiole, and often accompanied by male flowers too much This is mainly due to high night temperatures, lack of light, caused by excessive fertilizer and water. Therefore, we should strengthen the ventilation, light transmission, reduce night temperature, widen the day and night
