Hot weather prevents melons from cracking

Melon planting is very common in China, and melon planting is also very common. When planting melons, we should pay attention to doing a good job of management to avoid cracking melons and other problems affecting yield. Especially in hot weather, we must pay more attention to it, otherwise it will lead to melon cracking. What about preventing melons from cracking in hot weather? The following editor will give you a brief introduction, let's have a look!

1. Rational watering

In high temperature weather, watering is very important, and it is also an effective way to cool down. However, when we are watering, we must pay attention to control the watering time and amount of water. When watering, it is necessary to pour sufficient water into the expansion of muskmelon to ensure the normal expansion of melon fruit. Also pay attention to when watering inflated melon, do not water too much, avoid excessive water absorption and cracking of the fruit, especially about 10 days before harvest, it is best not to water, to prevent the phenomenon of cracking melon.

2. Use expansion agent cautiously

When planting melons, many people habitually use some plant growth regulators such as clopirazuron to dip flowers during the flowering period. This habit is good, but many people will apply a swelling agent after dipping in the flowers. In fact, there is no need to apply swelling agent after dipping in the flower, because the melon itself has its own law of growth and development. As long as normal management, control of fertilizer and water, even without the use of expansion agents and other hormones, melons can grow normally.

3. Rational fertilization

In hot weather, because the temperature is high and the light is strong, the loss of water and nutrition is relatively fast. Therefore, we should also pay attention to do a good job of fertilization, if there is no timely fertilization, then melons are very easy to crack due to lack of nutrition. Especially in the middle and later stage of melon, we must pay attention to timely fertilization, focusing on the application of calcium fertilizer and boron fertilizer to meet the nutritional needs of melon expansion and reduce the phenomenon of melon cracking.

4. Protective blades

Most of the hot weather refers to summer. In summer, the light intensity is very large, if it shines directly on the fruit, then it is very disadvantageous to the growth and development of the fruit, and it is easy to lead to the phenomenon of sunburn. So we should pay attention to protect the leaves around the fruit in summer. Use these leaves to shade the fruit. At the same time, it can also cover the grass and leaves on the fruit to avoid the aging and hardening of the pericarp.

5. Supplement of trace elements

Muskmelon in the whole growing period, the demand for trace elements is also relatively large. Therefore, we should also pay attention to replenishing sufficient trace elements for melons. After melons start to sit, we should combine watering work and spray appropriate amount of calcium chloride and boric acid solution and other foliar fertilizers. Spraying about every other week or so, about three times in a row, can supplement trace elements for melons and avoid cracking due to lack of trace elements.

The above is a brief introduction to the prevention of melon cracking in high temperature weather. That's all for today's introduction. This article is for reference only. I hope it can help you all.
