Detailed Explanation of the Latest Technical Methods for Spring Management of Jujube Trees
Jujube trees are distributed fairly widely in China, and jujubes are a fruit that many people enjoy eating very much. There is a large market demand for them in China. When growing jujube trees, after the trees 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 the spring management techniques for jujube trees. Let's take a look!
1. Spring Fertilization
The fertilization work for jujube trees in spring is very important. When fertilizing in spring, the main focus should be on early spring base fertilizer and late spring quick-acting fertilizer. 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 tree canopy. Then apply about 1 kg of urea per tree, together with an appropriate amount of superphosphate. If it is a young tree, it should be reduced appropriately.
2. Reasonable Watering
In early spring each year, there is generally relatively little moisture, not much rain, and the soil is also relatively dry. Therefore, in spring, in order to prompt 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 bud, to provide sufficient water for jujube tree budding. When watering, the watering method is very important, generally giving priority to furrow irrigation and hole irrigation. The amount of watering should be determined according to soil moisture content, weather and other conditions. 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 most suitable seasons for pruning jujube trees are generally winter and spring. In winter, if the jujube trees have not been pruned, then in spring it should be done in time. 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 degree of 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 methods and control the pruning intensity well.
4. Pest and Disease Control
Spring is a key period for pest and disease control in jujube trees. 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 turning of the tree plate. 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 produced, affecting planting benefits.
The above is a brief introduction to the spring management techniques for jujube trees. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
