What are the latest measures for preserving citrus flowers and fruits?
Citrus is a fruit that everyone rather enjoys eating. Citrus has a great many varieties, such as Shatang mandarin, Wogan, and others, all of which are in very high demand in our country's market and also have a certain amount of planting area. However, the phenomenon of citrus flower and fruit drop is relatively serious, so when planting citrus we must do a good job of flower and fruit preservation measures. So how exactly should it be done? Let's take a look together below!
1. Fertilizing and spraying
When planting citrus, we should pay attention to doing a good job of fertilizing and spraying, the purpose being to promote the maturity of spring shoots and strengthen the growth vigor of the citrus trees. A reasonable nutrient ratio can effectively reduce the phenomenon of citrus flower and fruit drop. Generally, before the main citrus trees have bloomed, spray some foliar fertilizer rich in trace elements. Then also pay attention to reasonably spraying flower and fruit preservation agents, which can noticeably improve the quality of the flower buds and achieve the goal of preserving flowers and fruits.
2. Water management
Water is very important to the growth of citrus. An appropriate amount of water can ensure the growth of citrus, increase yield, and enhance fruit quality. When planting, during fruit preservation we should keep the soil moist, which can noticeably improve the stress resistance of the citrus fruit-bearing mother branches. Pay attention to keeping moisture at a suitable level, preventing excessive water from causing root rot and leading to the phenomenon of flower and fruit drop in citrus trees. However, when encountering dry weather, also pay attention to doing a good job of watering to ensure that moisture remains within the range suitable for citrus growth.
3. Girdling for fruit preservation
Reasonably girdling citrus trees is a major fruit preservation measure. When planting, we should carry out girdling work on some vigorously growing trees. Usually the first girdling is done when physiological fruit drop occurs. Girdle the main trunk of the citrus tree in a complete ring, then at the time of the second fruit drop, girdle once more according to the growth vigor of the citrus tree and the number of fruits set. This can effectively increase the fruit-setting rate of citrus. When girdling, pay attention not to injure the xylem, and do not girdle old trees or weakly growing trees.
4. Scientific pruning
During the growth process of citrus trees, the problem of nutritional conflict between shoot-producing branches and fruit-bearing branches often arises. Therefore we should pay attention to doing a good job of pruning spring shoots, with the pruning targets mainly being water sprouts. After pruning spring shoots, we should also pay attention to doing a good job of pinching. When the retained spring shoots have grown to about 15 cm, that is the best time for pinching. Then when summer shoots grow to 4 cm, cut them all off and then remove the buds. This prevents excessive nutrient consumption, which would lead to insufficient fruit nutrition and the phenomenon of fruit drop. Concentrate the nutrients on the fruits and do a good job of flower and fruit preservation measures.
The above is a brief introduction to citrus flower and fruit preservation measures. When planting, we also need to ensure there is sufficient light, improve the ventilation and light penetration in the orchard, enhance lighting, and promote normal growth of citrus. That is all for today's introduction. This article is for reference only. Thank you all for reading and supporting.
