Why should jujube trees be cut around (time) what is the best fertilizer for jujube trees

Peach, jujube and orange trees are planted in many people's homes in the countryside. After all, every household in the countryside basically has land to grow some crops. For people who grew up in some cities, they don't know much about the growth of these crops. For example, why do jujube trees be cut in rings? What is the best fertilizer for jujube trees? Next, the editor will answer these two questions for you.

Why do jujube trees be cut in a circle (time)

The ring-cutting bark of jujube trees is also called open nail, which can improve the fruit setting rate and fruit yield of jujube trees. It is generally 5-8 years old to open armour after entering the full fruit stage. We now require 3-4-year-old trees to increase the fruit setting rate by cutting the nail ring, but not too early, and we must choose the vegetative branches of 1go 3 to promote the growth of the tree. We concluded that whether it is suitable to open a nail or not, we should take the trunk diameter of more than 5murmuri 8cm as the standard to determine whether the jujube tree should adopt the nail opening ring cutting technique. Otherwise, premature nail-opening and ring-cutting will reduce the crown, shorten the life span of jujube trees and make them become small and old trees.

What is the best fertilizer for jujube trees?

The main results are as follows: 1. Organic fertilizer is determined by yield: the amount of organic fertilizer is generally about 10 kg per young tree, and the fruiting tree depends on the yield. Generally, it is quantitatively applied with "jin jujube jin fertilizer", or 5-7 square meters per mu. If there is no organic fertilizer such as ring fertilizer, it can be replaced by bio-organic fertilizer, usually 2.5 kilograms per plant.

2. Determine the fertilizer according to the tree size. Chemical fertilizer as an auxiliary fertilizer of base fertilizer, while applying organic fertilizer, adding some nitrogen, phosphorus, potassium and medium trace elements fertilizer can accelerate the absorption of nutrients in early tree germination and ensure the growth and development of jujube in early spring. Generally speaking, the amount of chemical fertilizer applied per plant is 0.5 kg of urea, 0.5 kg of diammonium, and 1.5 kg of silicon, calcium, magnesium and potassium fertilizer. There is an appropriate increase in the number of big trees and a proper decrease in the number of young trees.

3. Topdressing generally includes sprouting fertilizer, flower promoting fertilizer, fruit expanding fertilizer and so on, mainly chemical fertilizer. Nitrogen and phosphorus fertilizer is the main fertilizer in the early stage, and phosphorus and potassium fertilizer is the main fertilizer in the later stage.

Planting techniques of jujube

1. Cultivation mode: first, dwarfing and dense planting type cultivation, which is mainly suitable for varieties with early fruit and small tree type, and the suitable row spacing is 2 m × 3 m or 3 m × 2 m. The second is intercropping cultivation, which is mainly suitable for varieties with medium or large tree type and late fruit, with row spacing of 8m to 10m. The distance between plants is 3 to 5 meters. Other crops can be planted among trees in the early stage.

2. Cultivation time: jujube can be cultivated in the whole dormancy period from defoliation to germination in the next year, which can be divided into spring planting and autumn planting. According to years of cultivation experience, if 2-year-old and more than 2-year-old root tiller seedlings are planted and immediately watered in spring, the survival rate can easily reach more than 90%, while the survival rate of autumn planting can hardly reach more than 90% even after planting. However, the survival rate of autumn planting can reach more than 70% even without watering, while the survival rate of spring planting without watering is obviously lower than that of autumn planting.

Pruning techniques of jujube trees

The main results are as follows: 1. Jujube pruning is suitable for winter. Jujube is dormant in winter, and there are many dead branches on the tree that are not suitable for existence. If it is not cut off in time, it will be very disadvantageous to the growth of jujube in the coming year. When the jujube is pruned in winter, the response of the jujube is slow, so the pruning activity will not have much effect on it, and at the same time it can stimulate the growth of the jujube in the second year. Secondly, jujube pruning can be carried out in summer, and jujube branches grow very vigorously in summer. in order to avoid the consumption of nutrients caused by excessive branch growth, jujube branches must be cut off. only in this way can the high yield of jujube be guaranteed.

2. Jujube pruning technology needs to follow some basic choices, such as the principle of "promoting forward and backward control, blocking and putting down". Specifically, it probably means that jujube trees should not be pruned as far as possible in the early growth stage, that is, 1 ~ 2 years. But when the jujube tree crown reaches the height we want, we should carry out pruning control, that is, blocking the upward growth of jujube trees and properly guiding them to develop horizontally.

In the above, the editor also introduces to you what kind of fertilizer is better for jujube trees, and the reasons why jujube trees should be cut around. In fact, it is not easy for many fruits to grow to maturity, because more or less problems are encountered in the production of fruits and vegetables, so we should cherish food and put an end to waste in peacetime.
