What causes muskmelon vine collapse? Let me teach you the prevention and control methods
Muskmelon, also called oriental melon, is an annual trailing herbaceous plant and a midsummer fruit that helps relieve summer heat, rich in protein, minerals, vitamins and other nutrients. During cultivation, muskmelon is prone to vine collapse, so how should it be solved? Let's take a look.
1. Symptoms of muskmelon vine collapse
Muskmelon vine collapse is a physiological disease that often occurs in the late growth stage of muskmelon and often leads to a decline in muskmelon yield. When vine collapse occurs, the muskmelon plants appear weak. When the weather is clear, the light is sufficient and the temperature is high, a sudden rainstorm occurs, followed by a sudden cold at night with an extremely large temperature difference that cannot be tolerated, making vine collapse highly likely; in mild cases the plants can slowly recover, while in severe cases most wither and die.
2. Causes
First, because water accumulates in the soil or the humidity is too low, it obstructs root respiration and leads to root oxygen deficiency; due to the activity of anaerobic bacteria, a large amount of harmful substances is produced, poisoning the root system. The root system cannot grow normally and loses the ability of leaf transpiration and root water supply, so the stems and leaves become weak, resulting in vine collapse. Second, in hot seasons the daytime temperature is relatively high and transpiration is vigorous, or after a long period of cloudy weather turning clear, the amount of water lost through transpiration exceeds the water supplied by the roots, causing the melon vines to wilt and lodge. This phenomenon is more prominent in the late growth stage; in the late growth stage the regenerative capacity of the root system is weaker, and once damaged it recovers slowly or cannot recover, so the harm is only greater at this time.
3. Prevention and control methods
When the sky clears after rain, water immediately, so as to lower the soil temperature and ground temperature. After watering, the drainage outlets should be opened promptly so that the water after irrigation drains out quickly. If the production area is relatively large or the water source is insufficient, the method of watering every other border or every other section can be used. After watering, cultivate the soil promptly to keep the soil temperature normal, which can also play a preventive role. On rainy days, drain water promptly as well to ensure there is no standing water in the field. After rain, cultivate the soil so that the soil is loose and root respiration remains normal. In addition, before field operations, wash hands and tools with soapy water to prevent transmission through sap friction. Spray pesticide as soon as pests and diseases first appear, about once every 10 days, and carry out continuous control 2 to 3 times depending on the condition.
