What causes premature aging in melons

Melon is a very common fruit in China, distributed throughout the country. The nutritional value of melon is very high, and it is welcomed by many people, so the melon planting area in China is now very large. However, when growing melons, many problems often arise that affect melon growth, and premature aging is one of them. So what is going on with premature aging in melons? Today the editor will give everyone a brief introduction. Let's take a look below!

1. Disease problems

In the early stage of melon growth, there are fewer diseases, because it is mainly vegetative growth at that time. But after melon enters the middle and late stages of growth, vegetative growth gradually shifts to reproductive growth, and at this time the vegetative growth of melon is very weak. Therefore, the resistance of the entire melon plant decreases, making melons prone to various diseases. This period is also the peak period for melon diseases, and melons often show premature aging and wilting due to various diseases. Among them, the diseases that easily cause premature aging in melons include fusarium wilt, gummy stem blight and various other diseases.

2. Physiological wilting

There are actually many causes of premature aging in melons, and physiological wilting is one of the main causes. When growing melons, the water demand of melons is relatively high. If the soil is too dry and lacks water, then melon plants are very likely to wilt due to lack of water. In addition, during the fruit-setting period of melons, we should also pay attention to thinning the fruit. Because if the number of fruits retained per plant exceeds the load capacity of the melon plant, then the plant will develop physiological wilting due to reasons such as nutrients and water being unable to be supplied in time or being supplied unevenly.

3. Root problems

The root system of melon is distributed relatively shallowly, with most of it distributed on the surface layer of the soil. If the soil plow layer is relatively shallow and the humidity is high, then when the temperature rises, transpiration will increase sharply. And the water absorbed and transported by the roots is slower than its evaporation rate, so it easily causes the plant to wilt from lack of water. And because the melon root system is distributed relatively abundantly in the surface soil layer, its nutrient absorption and supply capacity will decrease as a result. Therefore, it very easily causes stunted and weak melon growth, unable to meet the nutrient demand for fruit expansion, and finally causes the plant to age and die faster.

So during the fruit-setting period of melons, we should pay attention to ensuring balanced growth of the aboveground and underground parts of the plant. Not only should we do a good job of nourishing the roots, but the work of nourishing the leaves should also be carried out at the same time. If the root system is well protected, then the roots can be ensured to absorb sufficient nutrients. This provides sufficient raw materials for the leaves to synthesize organic substances. If the leaves are well nourished, the photosynthesis of melons can proceed normally, producing enough organic nutrients to meet the nutritional needs for the growth of melon stems, vines, roots and fruits, thereby reducing the premature aging of melons.

The above is a brief introduction to what is going on with premature aging in melons. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
