The best time 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 jujube tree girdling vary widely. So why do jujube trees need girdling? When should girdling be done? How should girdling be carried out? Let's find out 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 the content of soluble solids and sugar, and improves quality. Therefore, weighing the pros and cons in terms of overall yield, fruit nutritional value and taste, girdling is completely necessary in production.

2. Girdling time

As for the choice of girdling time, most people believe 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 4~5 flowers have bloomed on most bearing shoots. This is exactly 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 bloom stage of winter jujube is earlier than that of ordinary 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 stabilizes above 24 degrees. Some people 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, tools must be prepared, mainly including a sickle, a bark-opening tool, and a ring-barking knife. The one used more often on the market is a multifunctional jujube tree bark-opening tool, which consists of a handle, three U-shaped blades and a pointed blade tip. 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 tip is mainly used to remove 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 young bark, and finally wrap the wound with plastic tape to prevent pathogens from invading and infecting it, which would affect the wound healing again.
