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.

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.

Detailed Explanation of Key Techniques for Summer Management of Plum Trees
1 Summer pruning 1.1 Bud rubbing and shoot removal. Removing buds immediately after they sprout is called bud rubbing; when the sprouted buds develop into tender shoots, cutting or pinching them off is called shoot removal. 1.2 Pinching. Pinching can be done when new shoots grow to 10~15 cm. The number of pinchings depends on the tree's vigor and requirements

How to Prune a Plum Tree? A Detailed Guide to Planting and Pruning Methods
I remember when I was a child, there were several plum trees in front of our house. Every year when the plum trees bloomed, they were especially beautiful. But with the continuous development of the rural economy today, the plum trees in front of our house are long gone, and now many fruit grower friends have started planting

Winter pruning of plum trees must be done carefully and meticulously
Plum trees enter their full-bearing period 7 years after planting. The main task of winter pruning at this stage is to maximize yield per unit area and strictly control the formation of alternate bearing and bare zones at the rear. Winter pruning principles: Heavy pruning is the main approach, combining heavy and light pruning, to maintain the balance between growth and fruiting

Key Points of Shaping and Pruning Techniques for Schisandra chinensis Cultivation
The vines of Schisandra chinensis are soft and cannot stand upright, so they need to attach to a support and twine upward to grow. Therefore, its shaping work includes two tasks: setting up supports and pruning. (I) Setting up supports The growth amount of Schisandra chinensis in the year of planting varies greatly. Under conditions of poor seedling quality and poor management, plant height generally reaches only 50-60 cm, but after stumping pruning, the average growth height in the second year can reach more than 150 cm, and by the third year it can cover the trellis surface. Therefore, supports can generally be set up in the spring of the second year (early to mid-May). Supports can use trellis poles and sun-resistant polyethylene rope. Bamboo poles are often chosen as trellis poles. Bamboo poles are 2.0-2.2 m long, with a top diameter of 1.5-2.0 cm; sun-resistant polyethylene rope with a thickness of 3×15 strands is more suitable, with the upper end fixed to the first iron wire at the top. According to the plant spacing, 1-2 poles per plant. When the plant spacing is less than 50 cm, one pole can be set per plant, placed about 5 cm beside the plant; when greater than 50 cm, two poles per plant, evenly inserted or fixed on both sides of the plant. The part of the bamboo pole entering the soil is best coated with asphalt to extend its service life. The trellis poles are fixed to the three trellis wires with thin iron wire. In a Schisandra chinensis orchard with good seedling quality and management, the plant can reach a growth height of about 2 m in the same year, so supports should be set up in late May of the planting year to facilitate rapid plant growth.</p><p>(II) Shaping</p><p>The purpose of shaping Schisandra chinensis is, through artificial intervention and induction, to make it grow and develop according to the grower's requirements, so as to fully use the trellis space, effectively use light energy, reasonably retain vines, regulate the relationship between vegetative growth and reproductive growth, and cultivate robust and long-lived plants, so that they adapt to climatic conditions and facilitate farming, pest and disease control, pruning, and harvesting operations, thereby achieving the goals of high yield, stable yield, and high quality.</p><p>The tree form commonly used for Schisandra chinensis is a training method with one group or two groups of main vines, that is, each plant retains 1 group or 2 groups of main vines, which are respectively twined on evenly arranged supports. On each support, 1-2 fixed main vines are retained. Lateral vines and fruiting mother branches grow on the main vines. The spacing between each fruiting mother branch is 15-20 cm, evenly distributed. Fruiting branches and vegetative branches grow on the fruiting mother branches, as shown in Figure 5-3. The advantages of this shaping method are that the tree structure is relatively simple, and the shaping and pruning techniques are easy to master; cultivation can be carried out between plants and rows, making weed control convenient; the plant volume and load are small, and the requirements for soil, fertilizer, and water conditions are less strict. However, because the plant is relatively upright, it is prone to forming a situation of strong upper growth and weak lower growth, with the fruiting position moving upward, so control needs to be strengthened.</p><p>Each tree generally needs 3 years to form its tree shape. During the shaping process, special attention should be paid to the selection and retention of main vines. Branches with strong growth vigor, full growth, and plump buds should be selected as main vines. The number of main vines in each group must be strictly controlled. Too many main vines will cause adverse consequences such as weakened tree vigor and chaotic retention of branch groups.</p>

Detailed Explanation of Key Points of Winter Pruning Techniques for Cornus officinalis
Cornus officinalis, also known as zaopi, yaopi, and yurou, is a traditionally precious woody Chinese medicinal material in our country, with extremely wide medicinal uses. Foping County, Shaanxi Province, has a long history of cultivation and has already formed large-scale production. In 2001 and 2002, the county was respectively named "China's Hometown of Cornus officinalis" and "National-Level Cornus officinalis Medicinal Source Base County" by the State Forestry Administration and the Ministry of Science and Technology.

What are the key points of apple autumn pruning techniques?
I. Autumn physiological characteristics: 1. In the late stage of new shoot nutrition (August to November), leaf photosynthates are transported downward in large quantities into buds, fruits, branches and trunks, and roots. 2. In the fruit ripening stage, including early, mid and late maturing varieties. 3. In the late stage of flower bud differentiation,

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
