These technical key points must be mastered for spring management of jujube trees
Jujube trees are distributed over a fairly wide range in China, and jujube is also a fruit that many people enjoy eating very much. It has a large market demand in China. When growing jujube trees, after they safely overwinter, spring management is very important and directly affects the growth situation of that year. So how should jujube trees be managed in spring? Below, the editor brings you spring management techniques for jujube trees. Let's take a look!
1. Spring fertilization
Fertilization of jujube trees in spring is very important. When fertilizing in spring, base fertilizer in early spring and quick-acting fertilizer in late spring should be the main focus. Because spring is a season when all things revive, the growth vitality of jujube trees will also gradually increase, so the demand for nutrients is also very large. Around Qingming Festival each year, jujube trees begin to sprout, and at this time topdressing can be carried out. Dig a pit about 5 cm in diameter and about 35 cm deep at the outer edge of the canopy. Then apply about 1 kg of urea per tree as topdressing, together with an appropriate amount of superphosphate. If it is a young tree, then it should be appropriately reduced.
2. Reasonable watering
In early spring each year, moisture is generally relatively scarce, there is not much rain, and the soil is also relatively dry. Therefore, in spring, in order to promote the jujube trees to recover their growth as soon as possible and meet the water needed for their growth, attention must be paid to doing a good job of watering. Watering should be carried out before the jujube trees sprout, to provide sufficient water for jujube tree sprouting. When watering, the watering method is very important, generally mainly furrow irrigation and hole irrigation. The amount of watering should be determined according to factors such as soil moisture content and weather. Usually, spring watering and fertilization of jujube trees can be carried out at the same time.
3. Timely spring pruning
During the growth process of jujube trees, pruning work is indispensable, and the seasons most suitable for pruning jujube trees are generally winter and spring. In winter, if the jujube trees have not been pruned, then it should be done in time in spring. The pruning time in spring is generally around Qingming Festival. The tree shape of the jujube trees should be controlled well, overly long and overly dense branches should be cut off, and the density of the jujube tree shape should be adjusted. According to various factors such as the planting density, variety and tree age of the jujube trees, do a good job of pruning, adjust the pruning method and control the pruning intensity well.
4. Pest and disease control
Spring is a key period for pest and disease control in jujube trees, and in spring the intensity of pest and disease control must be strengthened. In spring, many pests and pathogens begin to become active, and corresponding measures must be taken for prevention to reduce the harm of pests and diseases. Prevention can be carried out through agricultural control measures such as scraping old bark, weeding and deep ploughing of the tree basin. At the same time, chemical control can also be carried out by spraying agents such as triadimefon and lime sulfur mixture in the orchard. Pests and diseases should focus on prevention. Once the disease occurs, losses have already been caused, affecting planting benefits.
The above is a brief introduction to spring management techniques for jujube trees. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
