The latest timing and method for girdling jujube trees explained in detail

In rural areas, many people plant some fruit trees at home, such as peach trees, jujube trees, and orange trees, and whether jujube trees need girdling is a headache for many farmers, and opinions on girdling jujube trees vary widely. So why do jujube trees need girdling? When should girdling be done? How should girdling be carried out? Let's take a look together.

1. The role of girdling

Many people believe that girdling can promote fruit set and young fruit development in jujube trees, increase the fruit-setting rate, and reduce flower and fruit drop. Girdling jujube trees during full bloom, regardless of tree age or fruit size, not only reduces flower and fruit drop and increases the fruit-setting rate, but also makes the fruit appearance more attractive, increases soluble solids and sugar content, and improves quality. Therefore, weighing the pros and cons in terms of overall yield, fruit nutritional value, and taste, girdling is absolutely necessary in production.

2. Girdling time

Regarding the choice of girdling time, most people believe that the most suitable period is the early full-bloom stage or the full-bloom stage, when about one-third of the flowers on the whole tree are open, or when most jujube bearing shoots have 4~5 flowers open. This is the period when flower quality is best, the number of set fruits is large, the fruits are large, the ripening period is uniform, and the commercial value is high. In recent years, there has been further understanding of this issue. It is believed that the initial flowering stage of winter jujube is earlier than that of general jujube varieties, and the temperature at its early full-bloom stage may not necessarily reach the critical point for fruit set, so girdling must wait until the temperature is stable above 24 degrees. Some also believe that the girdling time for winter jujube should be 2~3 days later than for other jujube trees.

3. Girdling method

Before girdling, prepare the tools, mainly including a sickle, a bark-opening tool, and a girdling knife. A multifunctional jujube tree bark-opening tool is used relatively often on the market. It consists of a handle, three U-shaped blades, and one pointed blade head. The large U-shaped blade can scrape off old bark, the small U-shaped blade is used for opening the bark, and the pointed blade head is mainly used to remove rough stubble and repair gaps. When girdling, peel off a ring of old protruding bark from the lower part of the trunk, then at the part where the old protruding bark has been removed, use a sharp knife to cut two rings around the trunk, reaching deep into the xylem, peel off the ring of tender bark, and finally wrap the wound well with plastic tape to prevent pathogen invasion and infection, which could affect wound healing again.
