Year round management plan for jujube trees, planting and management techniques for jujube trees

After the dates are harvested, they can be watered in winter, around 11 October.

Jujube trees, year-round management plan.

How do Xinjiang jujube trees survive the winter? When was the last water to be poured?

Planting and management techniques of jujube trees:

1. Site selection. Jujube trees have a strong adaptability, and the soil requirements are not high during the growth period, whether it is in barren beaches, hills and mountains or flat land, it can be planted. If the land condition is poor, it should be improved before planting, and the sandy land can be mixed with cooked soil and green manure to improve, and if it is planted in saline-alkali land, it can be built as a strip field and a terrace, which can play a role in drainage and reduce the salt content in the soil.

2. Dig a pit. According to a certain plant row spacing to dig the pit, the diameter and depth of the hole is about 60cm-80cm, and the size can be adjusted appropriately when digging the planting pit. If the soil is more fertile, the planting pit can be smaller.

When digging a hole, put the topsoil aside and the subsoil on the other, so that it will be more convenient to fill the soil. And apply some basal fertilizer, you can choose organic fertilizer, mix fertilizer and topsoil into the planting pit, and plant after watering.

3. Pruning. Before planting, the seedlings should be pruned properly, mainly the damaged, rotten and dry root system, which is more conducive to the growth of new roots. If it is planted in an arid orchard in the mountains, it is recommended to dip the bottom of the root system of the plant into mud for colonization, which is more conducive to the survival of the jujube tree.

Fourth, colonization. Put the pruned jujube tree into the planting hole, let the root system be stretched, and fill the soil into the planting hole, fill the soil to 2 3, to lightly lift the seedlings of the jujube tree, so that the root system and the soil are better combined, and finally fill the subsoil, and water the soil according to the solid soil. After planting, it is necessary to do a good job of replenishing water, watering in time when it is dry, and doing a good job of weeding.

Spray gibberellin once at the early flowering stage, and spray borax, zinc sulfate and ferrous sulfate 1 2 times from the flowering stage to the young fruit stage to promote fruit set.

In early to mid-June, the mixture of urea and borax was sprayed once during flowering and fruit setting.

A significant feature of the flowering period of jujube trees is the large amount of flowers, the flowering period is planted, and the fruit setting rate is low (generally only about 1%). The main reason is that multiple physiological cycles are carried out at the same time, the phenological period overlaps, and the nutrient competition between various organs is fierce. The flowering period of jujube trees begins in mid-to-late May and ends in early-to-mid-July, lasting more than a month.

The management of the flowering period of jujube trees is more complicated, not only to find ways to protect flowers and fruits, improve fruit setting rate, but also to promote the growth and development of young fruits, but also to prevent pests and diseases.
