Cucumber curved melon Cucumber curved melon not only affects the commercial quality of cucumber, but also affects the weight of the fruit. Because the fruit weight is inversely proportional to the degree of curvature, that is, the more the melon is bent, the lighter the weight of the melon. Therefore, prevention and control of cucumber bending is an essential skill for melon farmers. 1. Reason for occurrence: (1) Cucumber fertilization is incomplete, only the egg cells on the ovary side are fertilized, the whole fruit is unbalanced to form a curved melon, or the concentration is improperly controlled when treated with hormone sputum; (2) Physiological curved melon. Such as lack of fertilizer (potassium deficiency, boron, etc.), drought, low temperature (the temperature of flower bud differentiation period is too low, the temperature below 10 °C is too long) is easy to form a benton; (3) The cucumber grows weak, the photosynthetic products are less, the dry matter accumulation is less, and the fruits compete for nutrients, causing some bent fruits. Especially in the early stage of cucumber harvesting, the seedlings have just been slowed down, the leaf area is small, and the nutrient supply is not available. At the end of harvesting, the plants are aging, and the leaves are seriously ill, and they are easy to produce curved melons. Excessive leaf picking can also cause curved melons; (4) The environment changes drastically during the growth of cucumber, such as sudden clearing of the cloudy day, etc., high temperature and strong light cause water, and the nutrient supply is insufficient; (5) When grafting, there are few joints, poor healing, and poor nutrient transport, resulting in bent melon; (6) Mechanical bent melon. During the growth of cucumber, the melon strip is blocked by vines and the ground and cannot be elongated to form a curved melon; (7) Diseases and pests can also form curved melons. Infectious diseases such as cucumber powdery mildew, downy mildew, keratosis, blight, and other pests such as whitefly in the greenhouse can increase the number of curved melons. 2. Preventive measures: (1) Strengthen the management of fertilizer and water. The base fertilizer is mainly organic fertilizer. In the later stage, according to the fertilizer requirement of cucumber, the fertilizer with suitable formula is used to avoid partial application of nitrogen fertilizer, and at the same time pay attention to the supplement of medium and micro nutrient elements. (2) Strengthen environmental management. The nighttime temperature of cucumber is higher than 12 °C and lower than 18 °C, and the suitable temperature during the day is 28-32 °C. At the same time, watering is timely to prevent the relative humidity of the air from being too high or too low. Properly reduce planting density and increase photosynthesis. And strengthen the prevention and control of pests and diseases, pay attention to improve the quality of grafting when grafting. (3) Plant management. Preventing the bending of the melon caused by mechanical factors such as tendrils, frame materials, stems and leaves, etc., is mainly timely detection and timely adjustment. Under the premise of not affecting the yield and benefit, the benton is removed before and after the female flower. (4) When the cucumber leaves the old leaves, diseased leaves and yellow leaves, retain more than 30 functional leaves to ensure the formation of photosynthetic products.
