A detailed guide to fertilizing and watering jujube trees, master the latest management methods

Jujube trees have extremely important economic value, and their cultivation area is gradually increasing. To improve the yield and quality of jujube trees and increase income, the methods of fertilizing and watering jujube trees are extremely important. Below, the editor brings you the methods of watering and fertilizing jujube trees at different stages, hoping it can help you.

I. Fertilizing jujube trees

1. Apply base fertilizer early

The jujube tree is a tree species that forms flower buds in the same year. From the start of spring sprouting, as the bearing branch grows, inflorescences also appear in its leaf axils. Flower formation requires a large amount of nutrients, so base fertilizer should be applied early to improve the quality of flower bud differentiation. The base fertilizer is mainly decomposed farmyard manure, mixed with an appropriate amount of nitrogen-phosphorus-potassium compound fertilizer, and applied early after harvest to meet the needs of spring flower formation, flowering and fruiting of the jujube tree. If the base fertilizer is not applied in late autumn, it should be supplemented promptly after the soil thaws in the following spring. For young trees, fertilization is mainly applied in ring-shaped trenches, supplemented by radial trench application. After fertilizing, cover with soil and water. For trees in full fruit stage, generally about 1000 kg of farmyard manure is applied per tree, with an appropriate amount of compound fertilizer added.

2. Skillfully apply topdressing

Topdressing should be applied in time before flowering, after flowering and during the fruit enlargement stage each year. Quick-acting nitrogen fertilizer is applied near the flowering stage, about 1 kg of urea per tree in full fruit stage. After flowering, to reduce physiological fruit drop, 1-1.5 kg of nitrogen-phosphorus-potassium compound fertilizer is applied per tree in full fruit stage. After flowering and during the fruit enlargement stage, nitrogen-phosphorus-potassium compound fertilizer is applied as topdressing respectively. At the same time, attention should also be paid to foliar spraying. Generally, a 0.3% urea solution is sprayed once every half month in the early stage, and a 0.3% monopotassium phosphate solution is sprayed in the later stage. Foliar spraying should be done on a clear, windless morning before 10 a.m. or after 4 p.m. If there is dew in the morning, spray after the dew has dried.

II. Watering

Jujube trees are relatively drought-tolerant. To improve their fruit-setting rate, attention should be paid to timely watering, while loosening the soil to preserve moisture. In addition to timely watering after each fertilization, a thorough watering is also needed before the jujube tree sprouts to promote sprouting, branch and leaf growth, and flower bud differentiation. Jujube trees need a large amount of water for flowering and fruit setting. When drought occurs during the flowering period, watering is necessary. Watering during the flowering period can not only meet the water needs of branch and leaf growth, but also satisfy the fertilization process of pollen germination, improving the fruit-setting rate. When drought occurs during the young fruit stage, leaves will compete with young fruits for water, causing young fruits to drop, so watering should be done in time at this stage. In addition, spraying water during the flowering period can increase orchard humidity and promote pollination and fertilization.
