Melon crackers are a headache for melon farmers. Some of the melons that have cracked are completely rotted before they ripen. Some mature, even if they are mature, their storage time is greatly shortened, quality is reduced, production is reduced, and sales and prices are affected. Therefore, it is necessary to strengthen field management of melons, create intrinsic and external conditions conducive to the growth of melon, and prevent the occurrence of crack melons.

1, scientific fertilization
According to the requirement of fertilizer and water requirement during the growth of melon, the fertilizer should be supplied in a balanced manner. Do not apply water by blind irrigation. When fertilizing, it is necessary not only to apply enough basal fertilizer to meet the needs of early growth of melon, but also to timely fertilizer in the late growth stage of melon, to meet the requirements of melon in later growth period.
2, reasonable irrigation
On the one hand, it is necessary to pour the swelled water in time to promote the expansion of the melon fruit; on the other hand, after swelling the melon water, do not pour any heavy water. In particular, try to avoid watering for about 10 days before picking to prevent cracking of the melon.
3, protect the blade
Pay attention to protect the leaves near the fruit, use them to block the sun from the melon fruit, and avoid the fruit cracking caused by sun exposure.
4, control the temperature
In the production of greenhouses, insulation measures should be taken to keep the daily average temperature of the greenhouse at 15°C or higher; when the air is released, a smaller tuyere is to be smashed first, and then the tuyere should be gradually enlarged as the temperature rises; It is necessary to timely cover insulation materials such as grasshoppers to prevent a sudden drop in temperature.
5, protect the fruit
When the fruit is exposed to sunlight, newspapers can be used to cover the shade to prevent direct sunlight. Visor can also prevent green spots on the surface of the fruit and make the fruit beautiful. It is especially important during summer cultivation.
6, spray trace elements
After sitting on the melon, combined with watering with 0.3% calcium chloride and 0.12-0.25% boric acid solution for foliar spray, spray once every 7 days, even spray 2-3 times to supplement the lack of trace elements.
