How to prevent and control peach leaf curl? Those growing peach trees should know early
1. Symptoms and damage. This disease occurs from time to time in the south. When severe, it causes branch dieback and affects ornamental value. The disease mainly damages leaves. When leaves unfold in early spring, the leaf margins curl downward. Part of or the entire diseased leaf becomes blistered and enlarged, the leaf becomes thicker, brittle in texture, and yellow or red, and the leaves

Post-harvest management of peach trees cannot be relaxed; these tasks must be done well
After peach trees bear fruit, they consume a large amount of nutrients, and peach harvest happens to coincide with the rainy season. If technical management can be strengthened in time, it can increase the tree's nutrient accumulation, restore tree vigor as quickly as possible, form good flower buds, and create favorable

Control Methods for Yellowing Leaves of Winter Jujube Trees
Yellowing leaves of winter jujube trees are mainly caused by weakened tree vigor, and the causes of leaf yellowing are many-sided. First, diseases such as bacterial scab, jujube rust, and dieback cause early defoliation, resulting in insufficient stored nutrients in the tree and weakened tree vigor, which leads to

Management Techniques After Jujube Trees Lose Their Leaves
1. Increasing Fertilizer and Water. Jujube trees consume a large amount of nutrients during a year of growth and fruiting, which need to be replenished in time. Fertilize after the jujube trees lose their leaves and before the soil freezes. If no fertilizer was applied before the end of the year, it should also be applied as a supplemental dressing before sprouting in early spring. Fertilizer can be applied by broadcasting or trenching. Broadcasting means spreading

Experiences and Methods for Autumn Cultivation of Jujube Trees
1. Planting time: The earlier the autumn planting, the higher the survival rate. Mid-October to early November is preferable. 2. Digging the hole: Dig a planting hole 60 cm long, 60 cm wide and 60 cm deep, apply sufficient base fertilizer, fill with soil and water, and wait to plant. If the soil moisture is good, you can plant as you dig the hole, and water after planting. 3

Spring Pruning Methods and Technical Key Points for Densely Planted Jujube Trees
The small canopy open-center layered form has a trunk height of 80-90 cm. Suppress the secondary branches on the trunk and promote the development of 3-4 jujube heads (main shoots), so that the topmost jujube head extends upward to become the trunk extension branch, and the 2-3 jujube heads below are trained as main branches. In the second year, cut back the trunk branch leaving about 60 cm, and remove the

Methods for Preventing and Controlling Pests and Diseases of Winter Jujube Trees in Autumn and Winter, and Key Technical Points
After the beginning of autumn, winter jujube trees gradually enter the dormant period, and their tolerance to chemicals is relatively high. As temperatures drop, pests and diseases enter bark cracks, scars, branch forks, fallen leaves, fallen fruit, mummified fruit or the soil, where they lurk to overwinter. Therefore, it is necessary to seize the favorable opportunity for pest and disease control in autumn and winter,

Control Methods for Major Pests and Diseases in Jujube Cultivation
I. Major Diseases 1. Jujube rust. This disease mainly damages leaves, and sometimes also infects fruit. On the back of affected leaves, scattered light green spots appear, gradually turning pale grayish brown, and finally the lesions turn yellowish brown and produce raised summer spore piles. On the front of the leaf, opposite the summer spore piles

What are the control measures for drought damage in jujube trees?
The drought resistance of jujube trees is relatively strong; it is commonly known as the "iron-stem crop", but if drought persists for a long time and cannot meet the minimum water required for the growth and development of jujube trees, it will seriously affect the growth, development and fruiting of jujube trees. 1. Symptoms of drought damage (1) Growth and development stop. Because the root system cannot absorb water for a long time

Detailed Prevention and Control Methods for Low Fruit Set Rate in Jujube Trees
1. Pay attention to shaping and pruning. Because the bud types and growth and fruiting habits of jujube trees differ from those of other fruit trees, they are not sensitive to pruning responses. Therefore, pruning must follow the tree's natural tendency and shape the tree according to the branches, and pruning should be light. Winter pruning and summer pruning should be combined so that the main branches are reasonably distributed with clear layers. Select
