What Causes Hollow Watermelons with Thick Rinds? Latest Analysis
Watermelon is a fruit welcomed by many people; its taste is very sweet and fresh, and its nutritional value is also very high. Every summer, market demand for it is very large. Therefore, the planting area of watermelon in our country is also very large. However, when sowing watermelon, the phenomenon of hollow fruit with a thick rind often occurs. So what causes hollow watermelons with thick rinds? Below, the editor will briefly introduce the reasons to everyone. Let's take a look together!
1. Variety reasons
Now our country's agricultural technology is becoming more and more advanced, and its planting techniques have gradually matured. Therefore, the improvement of varieties is also quite good, and in most cases, the rind of watermelons nowadays is becoming thinner and thinner. Even so, however, the thickness of the watermelon rind will still vary due to the variety, with both thick-rind and thin-rind types. Among the thin-rind varieties, there are two types: tough-rind type and crisp-rind type. Generally, small and medium-sized varieties are thin-rind. On the contrary, if they are late-maturing large watermelon varieties, then most of them are thick-rind watermelons.
2. Climate reasons
During the growth period of watermelon, climate is also very important for the growth of watermelon. Especially during the flowering period and the fruit expansion period of watermelon, if it encounters continuous rainy days, low temperature, and a low-light environment, then it will have a very large impact on fruit setting in watermelon. Moreover, for fruits that have already set, it is likely to cause the phenomenon of hollow fruit with a thick rind. Especially for watermelons cultivated in open fields, the probability of hollow fruit with a thick rind is even higher. Therefore, when planting watermelons, we must pay attention to controlling the growing environment according to weather changes to ensure normal growth of the watermelon.
3. Fertilizer and water reasons
Compared with other fruits, the growth period of watermelon is relatively short, but it has a relatively large growth amount and yield. Therefore, watermelon's demand for fertilizer is still relatively large, and when applying fertilizer, we should pay attention to coordinating the use of organic fertilizer and chemical fertilizer. And we should also pay attention to the proportions of other nutrient elements, especially nitrogen fertilizer. The nitrogen fertilizer content must not be too high. If there is too much nitrogen fertilizer, then it is very easy to cause the phenomenon of hollow fruit with a thick rind in watermelon. Then, during the fruit expansion period of watermelon, attention should be paid to not lacking water, and avoiding excessive water causing the fruit to end its expansion period and mature early, resulting in cells not being plump and causing the phenomenon of hollow fruit with a thick rind.
4. Improper management
When watermelons are setting fruit, we need to properly control the fruit-bearing node position of the watermelon. The fruit-bearing node position must not be too low, otherwise it is very easy to cause thick rinds in watermelon fruit. Moreover, in order to advance the time to market of watermelons, many people will pollinate the first female flower within 10 nodes to promote fruit setting, resulting in a fruit-setting node position that is too low and causing the phenomenon of thick rinds. In addition, an imbalance of the boron element is also one of the main reasons for hollow watermelons with thick rinds. The boron element has the effect of promoting early maturity, improving quality, and enhancing stress resistance in watermelon. If the boron element is lacking, then it is also very unfavorable to the growth of watermelon.
The above is a brief introduction to the causes of hollow watermelons with thick rinds. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
