Watermelon cracks are a common phenomenon that not only affects the appearance of watermelons, but also leads to the loss of water and nutrients. This article will introduce some ways to prevent watermelon cracks to help you better protect your watermelon.
First of all, it is necessary to understand the cause of the watermelon crack. Generally speaking, watermelon cracks are caused by poor growing environment. For example, after a drought or heavy rain, a watermelon grows too fast, and the flesh does not match the growth rate of the peel, and the peel cannot withstand the pressure of the pulp, and a crack will occur. In addition, too much fertilizer or too thin soil, lack of trace elements, etc., can also lead to watermelon cracks.
In order to prevent watermelon cracks, the following measures can be taken:
1.Watering wisely.
During the growing watermelon, keep the soil moist and avoid excessive drought or overwatering. In dry periods, you can water in moderation, but don't let the soil get too wet so as not to affect the growth rate of watermelons. When there is a lot of rain, it is necessary to pay attention to timely drainage to avoid soil waterlogging.
2.Scientific fertilization.
In terms of fertilization, it is necessary to reasonably match nutrients such as nitrogen, phosphorus, and potassium to avoid over-fertilization or over-thinning of the soil. At the same time, trace elements, such as calcium, boron, etc., are added in an appropriate amount to enhance the toughness and disease resistance of the peel.
3.Use growth regulators.
When necessary, an appropriate amount of growth regulator can be used to adjust the growth rate of the watermelon to avoid the occurrence of cracks. However, it should be noted that the use of growth regulators should be reasonable and not excessive.
4.Choose the right breed.
Different varieties of watermelons also have different adaptability to the environment. When selecting varieties, it is necessary to choose those varieties with strong disease resistance, strong adaptability, and stable growth to reduce the occurrence of cracks.
5.Strengthen pest and disease control.
Pests and diseases can also cause watermelon cracks. Therefore, it is necessary to strengthen the prevention and control of pests and diseases, regularly check the growth of watermelon, and find and improve pests and diseases in time.
In short, the prevention and control of watermelon cracks needs to start from many aspects, including reasonable watering, scientific fertilization, the use of growth regulators, the selection of appropriate varieties and the strengthening of pest control. Only by taking comprehensive measures can you better protect your watermelon and improve its quality and yield.
