Causes and control measures of premature senescence of watermelon

In the middle and later stage of watermelon growth, premature senescence is very easy to occur if it is not managed properly. Premature senescence does great harm to watermelon, which will cause a large number of fruits not to ripen normally and seriously affect the yield and quality. So what about the premature senility of watermelons? Let's get to know it.

1. Symptoms of premature senility

The premature senescence of watermelon mainly occurred in the middle and later stage of growth, especially in the period from sitting melon to young fruit, the plant must be stagnant in vine growth, the expansion of young melon was slow or stopped, the leaves were thin and yellowish, and the vines appeared to wither after strong light at noon. In general, after the occurrence of premature senescence of watermelon, not only its yield is very low, but also the quality of the fruit is very poor, and the commercial value is very low, so many fruits are often bought without removal, so preventing premature senescence is an important measure to achieve high yield and high quality of watermelon.

2. Causes of premature senility

There are many reasons for premature senescence of watermelon, first, insufficient base fertilizer, untimely topdressing or improper fertilization, which will lead to lack of nutrients in watermelon, unable to supply nutrients needed for plant growth and fruit development, leading to nutrient depletion and premature senescence; second, diseases and insect pests, watermelon will occur a lot of diseases and insect pests, they will harm the growth of watermelon, serious opportunities to plant premature senescence Third, due to the influence of drought or soil stagnant water, the loss of water or retting roots will lead to premature senescence; fourth, excessive pruning; fifth, soil hardening, poor permeability, poor root development or root system can not absorb water and nutrients normally, premature senescence will occur over a long time.

3. Prevention and control methods

In order to prevent premature senility, first of all, the best fertilizer and water management is needed, base fertilizer should be applied according to soil fertility before planting, topdressing should be applied at all stages of growth, sufficient nutrients should be provided for plant growth, timely drainage should be carried out in time during drought and rainy season to avoid retting roots. Strengthen vine management, balance the vegetative growth and reproductive growth of watermelon, and ensure the nutrient demand of young melons. Prevention and control of watermelon diseases and insect pests should be done well, prevention is more important than treatment.

The above is the introduction of the causes and prevention measures of premature senility of watermelon. I hope it can help you. If you want to know more about it, please follow us.
