Cucumber planting in greenhouses often encounters the phenomenon of “flower toppingâ€. If the control is not timely, it will seriously affect the quality and yield of cucumber. So how do you need to improve this situation? The following small series will explain in detail the reasons and remedies for the development of this phenomenon. Reasons for the topping of cucumber flowers Unreasonable use of hormones Spraying strong fruit or ethephon can increase the number of female flowers; spraying plant growth regulators such as chlormequat can control the length of the plant, and the flower topping is caused by unreasonable concentration. Solution: Control the concentration of hormones used. Unreasonable use of pharmaceuticals Spraying azole fungicides to control cucumber diseases, due to unreasonable concentration, can lead to flower topping. Solution: Control the concentration of the drug used. Lack of nutrition Due to the low temperature in the deep winter season, the temperature is low, the illumination time is short and weak, the photosynthetic products of the plant are few, and the nutrient transport is blocked, which often leads to flower topping. Solution: Disperse flowers and thin fruit, spray a crazy titanium fertilizer every 10 days, increase crop photosynthesis and reduce plant burden. Water control Some vegetable farmers in the seedling stage or after planting, in order to seedlings, over-water control can lead to flower topping. Solution: Water control seedlings should be reasonable, don't overdo it. Unreasonable fertilization In order to pursue high yield of cucumber, excessive application of unfertilized chicken manure, duck manure, pig manure and other manure or fertilizer can also lead to flower topping. Solution: Use manure properly and be fully decomposed. How to do cucumber flower topping 1. For flower topping caused by burning roots, it should be watered in time, and timely tillage should be done after watering. 2. For the topping of the root-type flower, the temperature of the greenhouse should be raised. When the roots are found to be gray-white and water-immersed, stop watering, timely tillage, and if necessary, dry the soil. At the same time, remove the formed melon, and protect the roots. When the new root grows, it can be converted to normal management. 3. For the topping of flowers caused by low night temperature, the night temperature should be increased. The temperature in the first half of the night should be 15 °C, and it should be kept at 10 °C in the middle of the night. 4, the flower topping caused by the root of the wound, when cultivating, try to minimize the root damage to improve the vitality of the root system . Cucumber “flower topping†is a common phenomenon, but growers need to pay attention, because in severe cases, the yield and quality of cucumber will decrease. The above are detailed control measures, you can refer to it.
