Peach Tree Post-Harvest Management Like This, Heavy Fruit Covering the Branches Next Year
After peaches are harvested, the remaining nutrients produced by their leaves are redirected to supply the branches and trunk, promoting branch thickening, tissue maturation, and the accumulation of nutrients, creating better conditions for flower bud differentiation the following year. If managed properly during this period, it can not only increase tree nutrition and improve the tree's resistance to adverse environments, but also play an important role in flowering and fruiting and tree growth the following year. Therefore, the following technical measures should be effectively implemented: 1. Reasonable fertilization After peaches are harvested, fruit-picking fertilizer should be applied promptly. Fertilization

The importance of flower and fruit management in jujube trees, which growers must not neglect
The jujube tree is a species that produces many flowers, with a very large amount of flower differentiation, but affected by the tree body and environmental conditions, flower drop and fruit drop are very serious, and the harvested fruit rate is generally only 1-2% of the number of flower buds. The causes of flower and fruit drop in jujube trees are many-sided. First, from the phenological phases of jujube, it can be seen that the bud stage of the jujube tree coincides with the rapid growth period of the fruiting branchlets and the vigorous growth period of the jujube heads; in this period the phenological phases overlap and nutrient competition is very intense. When it enters the initial flowering stage, the jujube heads are still in a vigorous growth stage, while at this time the growth of the fruiting branchlets gradually slows. In the same period, several organs of the jujube tree

Timely Control of White Peach Scale on Cherry Trees
White peach scale on cherry trees is mainly found in cherry-growing areas and occurs commonly. Because the current climate is suitable and field humidity is relatively high, it has occurred quite severely in some fields. The damage has already caused leaves to basically fall off, and the pest population is extremely dense; up close and from a distance it looks completely white. It is estimated that the first-instar nymph stage of white peach scale should be around the end of September. The first-instar nymph stage is the best time to carry out spray control. Growers should strengthen field inspections and apply pesticide control immediately if infestation occurs, keeping the pest population base below the allowable economic level. Control methods

How to Treat Jujube Trees with Jujube Witches' Broom Disease? A Detailed Guide to Surgical Treatment Methods
1. Basis. The pathogen of jujube witches' broom disease is a mycoplasma-like organism, which mainly lives in the phloem of jujube trees and is conducted through the tree body via the sieve tube tissue. In winter, the mycoplasma-like organism moves from the aboveground parts to the roots to overwinter, and in the following spring flows back to the branches and trunk with the sap. On this basis, surgical treatment can effectively eliminate the mycoplasma-like organism. 2. Methods (1) Trunk ring sawing. Before leaf fall of the jujube tree and before sprouting the following year, starting from a point 40 cm above the ground on the trunk, use a saw to cut ring-shaped grooves in the trunk of the jujube tree. The requirement is to saw through the cortex, but not to damage the cambium. According to the severity of the disease,

What are the treatment methods for cherry tree wounds?
During the growth of cherry trees, long-term exposure to the sun makes the bark prone to aging and damage, causing rot and forming hollows, which affects the growth and lifespan of the cherry tree. Therefore, once a wound is found on a cherry tree, treatment measures must be taken immediately. Generally, first use a sharp knife to shave and scrape the wound clean, then disinfect it with a disinfectant such as a 5-degree lime sulfur mixture or ink, and finally apply a protective agent such as tung oil to prevent the wound from rotting and promote its healing. If the cherry tree wound has already become a hollow, it should be repaired. The method is: first dig out the rotten wood inside the hollow, then scrape clean the dead tissue at the edge of the hollow, then disinfect with a chemical agent, and use leaf mold and charcoal powder to wrap the rotten area to promote the restoration of its normal physiological functions. Observe carefully and keep the leaf mold and charcoal powder wrapping moist. If it dries out, water it to maintain a certain humidity. After such treatment, the hollow of the cherry tree will slowly grow adventitious roots. Combined with annual soil improvement, the adventitious roots will continue to grow, and finally extend into the soil and gradually thicken. The adventitious roots will transform into a trunk, becoming a healthier main trunk that sprouts and produces flowers.

Pruning and Flower and Fruit Management Techniques for Dense Planting of Apricot Trees
I. Training and Pruning 1. Training The apricot is a light-loving fruit tree; for dense planting orchards, a "V" shape with good ventilation and light penetration is recommended. The training method is as follows: plant at a row spacing of 3 m x 1 m; in the planting year, shorten the trunk by cutting to 40 cm; when new shoots reach 30 cm in spring, select and retain two symmetrically growing branches that extend toward the row middle, grow vigorously, and form a 30-60 degree angle with the trunk as the main branches, and let them grow naturally. Select and retain another 3-4 new shoots as auxiliary nurturing branches, remove the remaining new shoots, and at the beginning of May when the auxiliary nurturing branches are 20 cm long, pinch out the growing tips; in late June
