How to Increase the Sweetness of Pomelo? A Detailed Guide to the Latest Sweetening Methods
Pomelo is a very common fruit in our daily life, especially in autumn and winter, when the market demand for pomelo is even greater. Therefore, many people are now growing pomelo. However, most people often encounter many problems when growing pomelo that affect its quality. One of these is that the pomelo is not sweet enough. So how can we increase the sweetness of pomelo? Let's take a look together below!
1. Reasonable pruning
Reasonable pruning is a key measure for increasing the sweetness of pomelo. When pruning, we should control the number of prunings according to the age of the pomelo tree. If it is a young tree, then pruning should be carried out twice, in summer and winter respectively. For fruit-bearing pomelo trees, one additional spring pruning should be added, usually in February. When pruning, pay attention to focusing on cutting off the outer branches, and promptly prune branches that are too densely grown. Control the canopy of the pomelo tree well and promote the sprouting of inner branches. For the inner branches, remove excess branches, dead branches, and branches with pests and diseases. For trees that grow vigorously but do not flower or flower little, mainly use girdling. Improve the tree's ventilation and light penetration, enhance the tree's photosynthetic capacity, and thereby increase the sugar content of the pomelo fruit.
2. Expanding holes and improving soil
Improving the soil environment for growing pomelo trees is a key measure to ensure earlier fruiting, high quality, and high yield. Generally, the work of expanding holes and improving soil should begin in the second year after planting the pomelo tree, and it is best to complete it in the third year. When expanding holes and improving soil, first dig holes about 65 cm deep on both sides symmetrically at the drip line of the canopy. Then fill in sufficient green manure and burnt soil, along with an appropriate amount of medium and trace elements. Apply them in layers, then compact them to achieve the purpose of improving the soil.
3. Reasonable fertilization
Professional data surveys have shown that the calcium content in the soil is directly related to the acid content of pomelo. Calcium can not only neutralize the organic acids you give in the pomelo fruit, but also increase the weight of a single fruit. Potassium fertilizer, on the other hand, can enhance the photosynthesis of pomelo trees and increase the carbohydrate content, thereby achieving the goal of increasing the sweetness of the pomelo fruit. Therefore, we should pay attention to applying more calcium and potassium fertilizers. When fertilizing, trench application is usually the main method, and fertilization should generally be carried out about four times throughout the year. Also pay attention to controlling the application of chemical fertilizers, mainly using organic fertilizers, to improve fruit quality.
4. Fruit thinning and bagging
Reasonable fruit thinning is also a major measure for increasing the sweetness of pomelo. When our pomelo trees enter the fruiting stage, we should pay attention to promptly thinning out poorly developed deformed fruits, small fruits, and fruits damaged by pests and diseases. It is enough to keep the leaf-to-fruit ratio on the pomelo tree at about 200:1. Do a good job in fruit thinning, and after setting the fruit, wait until the young fruit grows to about 150 g and its transverse diameter is about 5 cm, then do a good job in bagging, which can effectively increase the sweetness of the pomelo fruit.
The above is a brief introduction to how to increase the sweetness of pomelo. That is all for today's introduction. This article is for reference only, and we hope it can be helpful to everyone!
