1. Symptoms of Melon Seedlings Melon Seedlings is a physiological disease that often occurs in the later stages of melon growth, often resulting in a decline in melon production. Melon plants showed weakness when the seedlings collapsed. When the weather was sunny, the light was full, and the temperature was high, the rainstorm suddenly fell. Then the sudden temperature difference at night was extremely unbearable. The collapsed seedlings are prone to occur. Withered. 2. Cause One is that the accumulated water in the soil or the humidity is too low, which will hinder the respiration of the root system, leading to hypoxia of the root system. Because of the activity of the anaerobic bacteria, a large amount of harmful substances will be produced and the root system will be poisoned. With the ability of the root system to supply water, so that the stems and leaves will weaken, and the seedlings will collapse. The second is that the temperature during the hot season is higher during the daytime, the transpiration is strong, or the weather is long and cloudy, the transpiration loss is greater than the water supply of the root system, which will cause the melon seedlings to wither and fall. This phenomenon is more prominent in the later stages of growth, and the regeneration of the root system is weaker in the later stages of growth. Once the damage is recovered slowly or cannot be recovered, the damage will only be greater at this time. 3. Prevention methods When it is fine after raining, water it immediately to reduce the ground temperature and the ground temperature. After watering, the drain should be opened in time so that the poured water can be quickly discharged again. If the production area is large or the water source is insufficient It can use the watering method of separate border or separate fan. After watering, plowing in time to maintain the normal soil temperature can also play a preventive role. In rainy days, drainage should be carried out in time to ensure that no water accumulates in the field. After raining, the soil should be cultivated to loosen the soil and ensure that the root system breathes normally. In addition, before the field operation, wash hands and knives with soapy water to prevent the frictional infection of the juice. Spraying should be started at the early stage of disease and insect pests, about once every 10 days, depending on the disease.
