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

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

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

Detailed Explanation of Key Points of Winter Pruning Techniques for Peach Trees
Winter pruning of peach trees can be carried out from after leaf fall until bud break the following year. During winter pruning, it is important to grasp the following points: 1. Be sure to determine the pruning plan and methods based on the growth and fruiting habits of peach trees. 1. Peach trees are extremely heliophilous (sun-loving) species. Therefore, in pruning, full

What are the tree management measures for peach tree cultivation?
Strengthen tree nutrition. Branch growth and leaf area expansion provide the basis for producing nutrients for flower bud differentiation, which is beneficial to flower bud differentiation. Excessive fruiting in the current year will weaken the tree vigor, leading to reduced shoot growth in that year. Conversely, if the plant grows too vigorously, it consumes

Management points for bagging peaches in peach tree cultivation
1. Bagging time. Combine with fruit thinning; bag as soon as the fruit is set. Orchards with peach fruit borer damage must be bagged before the peach fruit borer lays eggs. 2. Bagging targets. Mainly for mid-season and late-season varieties, especially late-season varieties, such as Bayuecui, Guoguangmi, Chushuhong, Hongxuetao

Key Points of Early High-Yield Cultivation Techniques for Peach Trees
In the spring of 2002, a peach orchard of 0.67 hm2 was established in Yutian County, Tangshan City, with the cultivars Shijiwang Tao and Shijihong Tao. In 2003, the average yield per 667 m2 was 890 kg; in 2004 it reached 2400 kg; and in 2005, 2006, and 2007 the yield stabilized at 3500 kg. The specific management techniques are described below.

How to prevent and control peach bacterial shot hole? A detailed guide to peach tree disease prevention and control methods
Peach bacterial shot hole is a widely distributed disease with a high incidence rate. Bacterial shot hole occurs in all peach-producing areas nationwide, especially in coastal and lakeside areas, in orchards with poor drainage, and in rainy years, where it often breaks out severely. If not controlled in time, it easily causes

How to Control the Alternate Bearing of Plum Trees? Practical Cultivation and Management Methods
1. Reasonable pruning to regulate tree vigor. On-year trees should be pruned early (before the onset of winter) and heavily. Remove dead branches, residual branches, slender branches, scorched-tip branches, diseased and pest-infested branches, and excessively dense, crossing branches. Do more heading back to stimulate shoot growth; for vigorous branches and competing branches, cut back hard, removing 2/3 to 3/4 of the branch or leaving only 3 to 5 buds. Thin flower buds early, prune away excess flowering branches, and reduce the fruit load. Off-year trees should be pruned late (around the beginning of spring), keeping flowering branches and thinning out non-flowering vegetative branches. Leave branches unpruned or bend them down to moderate tree vigor, retain as many flowers and fruits as possible, and increase the fruit set.
