The cause and control of the latest melon crack

Melons are becoming more and more popular in the market and more and more in demand. now the melon market is much more than before, the price is gradually rising, and the demand for quality is getting higher and higher. So attract a large number of people to start large-scale planting, but after a period of time, many friends will find that the melon has a very serious cracking fruit now. Serious harm to the quality and yield of muskmelon will also have a great impact on the economic interests of growers, so what causes fruit cracking? How to prevent and cure it? Let's have a look!

1. Uneven drying and wetting

In order to prevent the growth of stems and leaves in the melon seedling stage, many friends will control the amount of water in the early stage. in fact, this is very disadvantageous to the growth of muskmelon, which will make the melon seriously lack of water during the fruit expansion period, resulting in a thickening and hardening of the pericarp and premature aging. And after the fruit expansion period, although muskmelon needs a lot of fertilizer and water, many people will water too much, so that the interior of muskmelon begins to expand rapidly, resulting in fruit cracking. Therefore, it is necessary to control the water demand of melons in each period and maintain good growth.

2. Hormonal causes

Since planting melons, many people will use chlorourea plant growth regulators to improve the melon setting rate of melons. But most of them do not strictly follow the specifications and methods of the instructions. When using growth regulators, the concentration should be adjusted appropriately according to the change of air temperature. If the concentration is too high, especially in the early stage of the result, if the growth inhibitor is used, it should not be too high. Too high concentration will make the fruit surface aging prematurely, the internal growth rate accelerate, and the peel can not keep up with the internal growth rate, resulting in fruit cracking, so it must be used according to the usage of the instructions and the change of temperature.

3. Picking leaves too early

In the process of planting muskmelon, in order to reduce the incidence of diseases and insect pests, control the occurrence of diseases and enhance the permeability of the garden, the old leaves at the bottom of the plant will be removed. However, if the old leaves are removed too early or too much, the fruit at the bottom of the plant will lose the shading effect of the leaves. Muskmelon is exposed to the sun for a long time, which is the premature aging of the pericarp and the formation of round tortoise cracks when the pericarp shrinks. Therefore, it is necessary to control the time and number of old leaves to be removed to avoid long-term direct sunlight of the fruit.

4. Trace elements

It may also be due to the soil, the soil is too hard, the speed of water infiltration is too slow, resulting in poor root permeability, affecting the normal absorption of nutrients. If there is a lack of trace elements such as calcium in the soil, especially in the soil of continuous cropping, fruit cracking occurs more often, strengthen the soil ploughing, frequently watering, properly combined with topdressing, loosen the soil and enhance the air permeability of the soil. reduce diseases caused by crop physiology.

The above are several reasons for melon fruit cracking, fruit cracking is a problem that occurs in many fruits, we must not underestimate fruit cracking, because if a fruit begins to crack, then it is likely to be a large area of fruit cracking. I hope you will pay attention to it. The above points may not be complete, but they are absolutely but more important. I hope they will be helpful to you.
