Causes and control methods of seedling collapse of muskmelon

Cantaloupe, also known as cantaloupe, is an annual vine herb, is a kind of summer fruit, has the main anti-summer, rich in protein, minerals, vitamins and other nutrients. Melon is prone to collapse in the process of planting, so how to solve it? Let's take a look.

1. Symptoms of melon seedling collapse

Muskmelon seedling collapse is a physiological disease, which often occurs in the late growth stage of muskmelon, which often leads to the decline of melon yield. Muskmelon plants show weakness when the seedlings collapse, when the weather is clear, the light is sufficient, the temperature is high, and then the sudden cold temperature difference at night is extremely unbearable, so it is easy to collapse, and if it occurs lightly, it can slowly recover, and most of the serious ones will die.

2. The cause

First, because the soil water or humidity is too low, it will hinder the respiration of the root system, resulting in a lack of oxygen in the root system, because the activity of anaerobic bacteria will produce a large number of harmful substances, so that the root system can not grow normally, and the ability of foliar transpiration and root water supply will be lost, so that the stems and leaves will be weak, resulting in seedling collapse. Second, in the high temperature season, the daytime temperature is higher, the transpiration is exuberant, or the weather changes from overcast to sunny for a long time, and the transpiration water loss is greater than the root water supply, which will lead to melon and seedling lodging. This phenomenon is more prominent in the late growth stage, and the regeneration ability of the root system is weak in the later growth stage. Once the damage is slow or unable to recover, the harm will only be greater.

3. Prevention and control methods

When it is sunny after rain, it should be watered immediately, so as to reduce the mild ground temperature, and the drain should be opened in time after watering, so that the water can be discharged quickly after watering. If the production area is large or the water source is insufficient, you can use the border or fan watering method, ploughing in time after watering to keep the soil temperature normal, which can also play a role in prevention and control. Drainage should be carried out in time on rainy days to ensure that there is no stagnant water in the field, and ploughing the soil after rain to make the soil loose and ensure normal root respiration. In addition, before field operation, wash hands and knives with soapy water to prevent sap friction and infection. Spray should be started at the initial stage of the onset of diseases and insect pests, once every 10 days or so, and continuous prevention and control for 2 or 3 times depending on the disease.
