What causes hollow watermelons with thick rinds
Watermelon is a fruit loved by many people; it tastes very sweet and fresh and has high nutritional value. Every summer, market demand for it is very high. So the planting area of watermelon in our country is also very large, but when growing watermelons, hollow fruit with thick rinds 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!
1. Variety reasons
Our country's agricultural technology is becoming more and more advanced, and its planting techniques have gradually matured. Therefore, variety improvement is also quite good, and in most cases, the rinds of current watermelons are becoming thinner and thinner. Even so, the thickness of watermelon rinds will still vary due to variety, giving rise to thick-rind and thin-rind pollen. Among thin-rind varieties, there are two types: tough-rind type and crisp-rind type; generally, small and medium-sized varieties are thin-rind. Conversely, if they are late-maturing large watermelon varieties, most are thick-rind watermelons.
2. Climate reasons
During the growth period of watermelon, climate is also very important to its growth. Especially during the flowering period and fruit enlargement period of watermelon, if it encounters continuous rainy days, low temperature, and a weak-light environment, it will have a very large impact on fruit setting, and for fruits that have already set, it is likely to cause hollow fruit with thick rinds. Especially for watermelons cultivated in open fields, the probability of hollow fruit with thick rinds is higher. Therefore, when planting watermelons, we must pay attention to controlling the growing environment according to weather changes to ensure normal growth of watermelons.
3. Fertilizer and water reasons
Compared with other fruits, the growth period of watermelon is relatively short, but it has relatively large growth and yield. Therefore, watermelon's demand for fertilizer is still relatively large, and when fertilizing, we must pay attention to coordinating the use of organic fertilizer and chemical fertilizer. And we must 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, it is very easy to cause hollow fruit with thick rinds in watermelons. Then, during the fruit enlargement period of watermelon, pay attention not to lack water, and avoid excessive water causing the fruit to end the enlargement period and mature early, resulting in insufficiently filled cells and the occurrence of hollow fruit with thick rinds.
4. Improper management
When watermelons set 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 fruits. Moreover, many people, in order to bring watermelons to market earlier, pollinate the first female flower within 10 nodes to promote fruit setting, resulting in too low a fruit-setting node position and the occurrence of thick rinds. In addition, boron element imbalance is also one of the main causes of hollow watermelons with thick rinds. Boron element has the effect of promoting early maturity, improving quality, and enhancing stress resistance in watermelons. If boron element is lacking, it is also very unfavorable to the growth of watermelons.
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!
