Cucumber flower topping is a common physiological issue in greenhouse cucumber cultivation. It typically manifests as shortened internodes near the growing tip, with no formation of male and female flower clusters or new leaves. This condition, known as "flower topping," often occurs during the early fruiting stage and significantly affects both yield and fruit quality.
There are generally three main types of cucumber flower topping:
1. **Developmental disorders**: Low temperatures during the early growth phase, combined with large day-night temperature fluctuations, can hinder vegetative growth. When plants grow too rapidly due to this imbalance, they are more prone to "flower topping."
2. **Root injury type**: High temperatures and drought conditions in the greenhouse, especially when the soil is dry, can lead to root damage. Over-fertilization without sufficient water may cause root burn, while overly wet soil with low ground temperature can also harm root development.
3. **Physiological deficiency type**: Poor soil conditions, such as low nutrient availability or weak root activity, can result in the plant's inability to absorb necessary nutrients, leading to "flower topping."
To manage this issue, several control measures can be taken:
1. **Temperature management**: Maintain optimal temperatures and avoid extremes. Loosen the soil regularly to improve soil warming. If needed, apply fertilizer and water first before warming the soil to stimulate root growth.
2. **Fertilizer and water management**: Apply small amounts of fertilizer multiple times, ensuring organic fertilizers are fully decomposed to avoid root damage. Water appropriately, avoiding overwatering that could lower soil temperature and affect root health.
3. **Remedial actions**: For plants already showing signs of flower topping, remove some female flowers and spray with potassium dihydrogen phosphate diluted 300 times. When root development is affected, ensure the soil moisture reaches about 22% and air humidity stays around 65%. Proper watering can help restore normal growth quickly.
By understanding the causes and implementing these strategies, growers can effectively reduce the occurrence of cucumber flower topping and improve overall crop performance.
