How to prevent melon from cracking

Melon cracking is a headache for fruit growers. Some of the cracked melons rot completely before they mature. Even if they mature, their storage time will be greatly shortened, their quality will be reduced, their yield will be reduced, and their sales and prices will be affected. Therefore, in order to strengthen the field management of melon, create internal and external conditions conducive to melon growth, and prevent the occurrence of fruit cracking, the methods are as follows: 1. Scientific fertilization. According to the melon growth period needs, water demand law, balanced supply of fertilizer and water. When applying fertilizer, not only enough basal fertilizer should be applied to meet the needs of melon growth in the early stage, but also topdressing should be applied in time at the later stage of melon growth to meet the fertilizer requirements of melon growth in the later stage. 2. Reasonable irrigation. On the one hand, it is necessary to irrigate melon water in time to promote melon fruit expansion; on the other hand, after watering melon water, do not irrigate water again, especially about 10 days before picking, so as to prevent melon cracking. 3. Protect the leaves. Pay attention to protecting the leaves near the fruit, using them to block the sun for the fruit, avoiding fruit cracking caused by aging caused by direct sunlight. 4. Control temperature. In greenhouse production, insulation measures should be taken to keep the daily average temperature of the greenhouse above 15℃; when releasing air, first remove a small tuyere, and then gradually increase the tuyere with the increase of temperature; when cold weather occurs, cover the straw mat and other insulation materials in time to prevent the sudden decrease of temperature. 5. Protect the fruit. Paper bags can be made of newspapers for shading to prevent direct sunlight. Sunshade can also prevent spots on the fruit surface and make the fruit beautiful, especially important in summer cultivation. 6. Spraying trace elements. After sitting melon, combine watering with 0.3% calcium chloride and 0.12%~0.25% boric acid solution for foliar spraying, spray once every 7 days, continuous spray 2~3 times, in order to supplement the deficiency of trace elements.
