A Detailed Guide to Common Pests and Diseases of Plum Trees and Their Control Methods
After the first pinching of the plum tree, pinch the new secondary shoots when they reach 20 cm, and pinch the developing branches when they reach 60-80 cm. If there are many branches, some can be thinned out; if the branches are not too dense, thin as little as possible and control more. Before mid-July, the weeds in the orchard must be completely removed

How to prevent frost damage in plum trees? Key technical points for frost prevention when growing plum trees
Frost injury and freeze damage refer to the phenomenon in which the soil and plant surface temperatures drop to 0°C or below 0°C for a short time at night during the growing season, or when frost occurs, causing damage to the young and tender parts of fruit trees. In China, the average annual area affected by frost damage reaches 340,000 km2, and in the worst year it reached 7

Plum tree training and pruning methods and key technical points
① Training. The tree form can be natural open-center, multi-main-branch natural form, or Y-shape. For young trees, the trunk height is set at 30-50 cm. After sprouting, keep 5-6 buds as main branches; when the main branches are 50-60 cm long, leave 40 cm and pinch off the tips. In August, keep 2-3 permanent main branches, and pull the extra 2-3 main branches apart to make them droop, so they can bloom and bear fruit the following year. Later, as appropriate, train them into medium-to-large fruiting branch groups.

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.

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

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.

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

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

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
