Key Technical Points for Raising Hami Melon Seedlings and Planting in Autumn
1. Sowing In the Shanghai region, raising Hami melon seedlings in autumn is best done at the end of July and the beginning of August, choosing high-yield, high-quality Hami melon varieties suitable for cultivation in the Shanghai region. First dry the Hami melon seeds in a constant-temperature chamber at 40°C for 24 hours, then keep the temperature constant at a high temperature of 70°C for dry-heat sterilization

Detailed Explanation of the Cleft Grafting Method and Top Grafting (Topworking) Technique for Plum Trees
1. Preparation before grafting: Generally in February, cut healthy, pest-free 1-year-old branches as scions. It is best to use fully mature, plump-leaf-budded, well-developed branches from the upper outer canopy of trees that have already fruited. Cut them into 15-20 cm segments (with 3-5 buds).

Detailed Explanation of Key Points of Plum Trellis Cultivation Technology
In recent years, the plum cultivation area in various regions has increased rapidly. Most tree shapes are natural open-center or sparse stratified forms, and pruning adopts the method of light pruning, long shoot laying, and retaining many branches. Although this has played a certain role in early fruiting, some new problems have also appeared, such as slow formation of young trees,

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

What are the key points of autumn management techniques for plum orchards?
Autumn is an important period for plum trees to restore tree vigor and accumulate nutrients in the tree body. Applying scientific management measures can increase the reserve of tree nutrients, promote further differentiation of flower buds, and lay a good foundation for high yield and high quality in the following year. Through many years of practice, whenever the management techniques of this period

Detailed Explanation of the "Three Early" Cultivation Techniques for Plums
"Three Early" cultivation techniques for plums: 1. Reasonable pruning to promote early flower bud formation: In the year the plum is planted, when the new shoots grow to about 30 cm, pinch off the growing tips to control growth, stimulate secondary shoots and form flower buds. For example, on Misi plum, Oishinaka, and Oishiwase, after pinching, 40% of the secondary shoots can form flower buds, while plum trees not pinched in summer generally do not form flower buds that year. During winter pruning in the first year, current-year branches are generally left unpruned and laid flat, while densely crowded branches, water sprouts and shade-casting branches are removed by thinning. In this way, a large number of clustered flower buds can form on the laid-flat branches of that year. During winter pruning in the third year, the branches that were laid flat are appropriately retracted to prevent the tree from weakening. In subsequent years' winter pruning, the same pruning sequence is used.

Plum Seed Sowing and Seedling Raising Methods and Key Points of Seedling Stage Management Techniques
Plum Seed Sowing and Seedling Raising and Seedling Stage Management Methods: 1. Nursery Site Selection The nursery site should be selected in a place with flat terrain and loose, fertile soil. Before winter, irrigate first and plow deep. In late March, prepare the land and lay plastic film. The plastic film is best laid in a north-south direction so that the seedlings can receive uniform light

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.

Scientific Fertilization Methods and Technical Points for Plum Cultivation
I. Fertilizer Types 1. Base fertilizer: Base fertilizer is a fertilizer that can supply plum trees with various nutrients over a relatively long period. It is generally dominated by slow-release farmyard manure, such as compost, barnyard manure, crop straw, green manure, fallen leaves, etc. An appropriate amount of quick-acting nitrogen fertilizer can be added to the base fertilizer to meet the large amount of nitrogen needed by plum trees during early spring germination and flowering.
