Detailed Explanation of the Method for Raising Jujube Seedlings by Root Cutting and Returning to the Nursery
To raise jujube seedlings by root cutting and returning them to the nursery, first select plants of excellent quality and free from pests and diseases as mother plants. Before budbreak, dig a trench 30-40 cm wide and 40-50 cm deep around the outer edge of the mother plant's canopy to cut the jujube roots, and use scissors to trim the cut root wounds smooth. Apply decomposed organic fertilizer, about 75 kg per plant, mix it with moist soil, fill it into the trench and tread it firm. If conditions permit, it is best to irrigate thoroughly once. Then cover with a layer of loose soil to conserve moisture. After the jujube roots are stimulated, a large number of clustered root-sucker seedlings will appear on the ground near the trench in May-June. Management of the root-sucker seedlings should be strengthened in a timely manner. After budbreak, remove excess buds; the principle is to remove the dense and keep the sparse, and remove the weak and keep the strong, generally with a plant spacing of about 15 cm, so as to ensure normal growth of the seedlings.

What are the control methods for the peach fruit borer on jujube trees?
Also known as the peach borer moth and peach spotted borer moth, it is an omnivorous pest distributed throughout the country. Its larvae damage the fruits or seeds of many plants such as winter jujube, peach, plum, persimmon, chestnut, apple, pear, pomegranate and hawthorn. When the fruit is damaged, it becomes filled with insect droppings, causing rot, and in severe

What are the control methods for the tortoise wax scale on jujube trees
In recent years, the tortoise wax scale (Ceroplastes japonicus) has spread through the counties of our city, causing serious damage, which has generally weakened the vigor of jujube trees, significantly reduced yields, and even caused total crop failure. In order to effectively carry out chemical control of the tortoise wax scale on jujube, since 1996 we have carried out control trials for 4 consecutive years

A New Method of Grafting Jujube Trees: A Detailed Guide to the Chip Budding Technique
Chip budding jujube trees is a good method for developing fine jujube varieties. It is introduced as follows: 1. Tools: pruning shears, grafting knife, plastic strips. 2. Collection and storage of scions. ① Spring-summer grafting: (late April to late June), before the end of March, collect well-developed, pest-free one-year-old jujube head branches from a mother tree orchard of fine varieties, cut off the secondary branches (leaving 2 cm), store them in a cool, moist place, bury them well in moist sand, or store them in a cellar less than 4 m deep or suspend them down a well (below 7°C). In this way the scions can be stored until late June to early July. ② Autumn grafting: (early August to mid-to-late September) collect current-year lignified branches, immediately remove the secondary branches and leaves, and use them as soon as they are collected. If they need to be stored for a short time, they can be placed in a container holding 10 cm of clean water and suspended down a well 0.5-1 m above the water surface or placed in a cellar.

Seven precautions for girdling jujube trees that growers must remember
I think everyone is very familiar with jujube trees, and many people should have witnessed the growth process of jujubes. As the saying goes, "Eat three jujubes a day, and youth will never fade." Therefore, jujubes are deeply loved by everyone. Do not underestimate those individual jujubes; they actually contain great nutritional value.

Detailed Explanation of the Hook-Shaped Cleft Grafting Method for Jujube Trees, Step-by-Step Guide
1. Tools used: pruning shears, grafting knife (straight sharp knife), plastic strips. 2. Collection of scions: Collect well-developed, pest- and disease-free 1-year-old jujube head branches or current-year lignified branches, remove secondary branches (leave 2 cm long) and leaves, and use them immediately after collection. If

Prevention and Control Methods for Bark Cracking and Trunk Dehydration in Young Jujube Trees
Yining County once developed jujube trees on a large scale. In years with heavy winter snowfall, when the snow melted in early spring, the trunk below the snow line (about 20 cm high) was soaked by melting snow water and exposed to wind, causing rot and bark splitting, which blocked the tree's vascular tissue and led to drying and death.

What are the control methods for iron deficiency chlorosis in jujube trees?
Distribution and harm: Yellow leaf disease occurs in many jujube-growing areas, among which iron deficiency chlorosis is relatively common and is a physiological disease. It can cause tree decline, affect jujube yield, and in severe cases can cause tree death. 1. Symptoms: Mild iron deficiency

Four common grafting methods for jujube tree cultivation
1) Single-bud bark grafting: From May to September, when the rootstock begins to slip bark, grafting can be done every day. Choose sour jujube rootstock under 5 years old with a diameter of about 1.5 cm; use lignified, disease-free and pest-free growing shoots as scions. 2) Subcutaneous grafting: From spring when the rootstock

Detailed Explanation of Summer Pruning Methods and Techniques for Jujube Trees
Traditional jujube orchard management is relatively extensive, and summer pruning is generally not carried out, resulting in disordered tree shape and small angles of scaffold branches. Although the tree is tall, ventilation and light penetration are poor, and yield is low. Summer pruning of jujube trees not only facilitates ventilation and light penetration, but also regulates tree nutrition and increases fruit set
