What causes premature senescence in melons? Latest cause analysis

Melon is a very common fruit in China, and it is 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 also very large. However, when growing melons, many problems often appear and affect the growth of melons, and premature senescence is one of them. So what causes premature senescence in melons? Today the editor will give you a brief introduction. Let us take a look below!

1. Disease problems

In the early growth stage of melon, there are relatively few diseases because growth is mainly vegetative at that time. However, after melon enters the middle and late growth stages, 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 declines, making melon susceptible to various diseases. This period is also the peak period for melon diseases, and melons often show premature senescence and withering due to various diseases. Among them, diseases that easily cause premature senescence in melon include Fusarium wilt, gummy stem blight and various other diseases.

2. Physiological wilting

There are actually many causes of premature senescence in melon, and physiological wilting is one of the main causes. When growing melons, the water requirement of melon 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 melon, we must also pay attention to fruit thinning. 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, and most of it is distributed in the surface layer of the soil. If the soil plough layer is relatively shallow and the humidity is high, then when the temperature rises, the transpiration rate will rise sharply. However, the water absorbed and transported by the roots is slower than its evaporation rate, so it easily causes water deficiency and wilting in the plant. Also, because the melon root system is distributed in relatively large amounts in the surface layer, its nutrient absorption and supply capacity will decline as a result. Therefore, it is very easy for melon growth to become thin and weak, unable to meet the nutrient demand for fruit enlargement, and finally causing the plant to age and die faster.

Therefore, during the fruiting period of melon, 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 in root maintenance, but leaf maintenance should also be carried out at the same time. If the root system is well protected, then the roots can absorb sufficient nutrients. This provides sufficient raw materials for leaves to synthesize organic substances. If the leaves are well maintained, then the photosynthesis of melon can proceed normally, producing enough organic nutrients to meet the growth nutrient needs of melon stems and vines as well as roots and fruits, thereby reducing premature senescence in melon.

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