Time and method of pruning jujube trees

Jujube is a kind of small tree fruit tree. In order to coordinate the relationship between vegetative growth and reproductive growth, it is often necessary to prune the tree, but pruning also has other advantages. Pruning generally has pruning time and period, can not be trimmed at will, there are certain methods, mainly better methods for the tree. Now let's take a look at how to trim it properly.

1. Pruning young trees

The first-year fixed value of young trees is only small saplings, but it is also required for pruning. Generally, the trunk should be fixed first after planting, generally 70 cm off the ground, the lateral branches in the fixed trunk should be removed, the upper branches should be kept, about 4 to 5 branches should be left, and the top of the fixed trunk should be cut off to promote new branches and do main branches. in addition, lateral branches can also be cut short, so that the plant can grow more vigorously. After plastic surgery, the general main branch to leave 50 cm short, secondary branches to pick the heart, remove excess branches, staggered branches, step by step increase.

2. Pruning before flowering

Many flowers, much fruit, but a lot of fruit, so it is necessary to prune reasonably before flowering, improve tree nutrition, and protect flowers and fruits. Remove excess leaf buds and pull out new shoots in May. Prune mainly before the bud appears. Need to remove the growing jujube head, mainly leave backbone branches, fruit branches, can go to part of the auxiliary branches, ventilation and light, promote nutrition accumulation to avoid falling flowers and fruits.

3. Pruning in the fruiting period

Fruiting trees generally grow for several years, with plump crowns and many branches, but old branches can be cut short to promote new ones, and strong shoots should be selected to retain them. Replace the old branch, which can guarantee the amount of result. The crown is too large, dense and impenetrable, weak branches, drooping branches, interspersed branches, internal staggered branches should be removed. Ensure good tree shape and reduce nutrition consumption. Lengthen the branch to pick the heart, leaving nutritional results. Some of the outer extension branches need to be removed to disturb the tree. Results the branch group should be updated year by year.

4. Pruning after fruit harvest

After the fruit is picked, the tree has consumed most of the nutrition in order to bear fruit, so it is necessary to accumulate nutrients to ensure the tree potential. Generally, it is necessary to cut off some withered branches or old branches that do not bear fruit, and for those branches that do not grow well, the drooping main branches should be tightened, and the drooping outer branches can be cut short. At this time, if you still draw new shoots, you must remove them in time, but you can choose to stay strong after fertilizing.

The pruning of jujube trees is mainly carried out with the growing period, the main task of pruning young trees with fixed stem, and the main purpose of pruning at flowering and fruit stage is to protect flowers and fruits and improve fruit setting rate. The main purpose of cleaning the branches after fruit picking is to maintain the tree momentum.
