Key points of early high-yield cultivation techniques for pear trees
1. Large holes and deep planting. From April 5 to 10, select healthy, pest-free one-year-old seedlings with a diameter of more than 1.0 cm at 2 cm above the graft union and a height of more than 1.5 m. Before planting, cut off damaged roots and overly long roots, soak them in clean water overnight, and the next day dip the seedlings in mud slurry before planting. The planting hole should be 1 m long, 1 m wide, and 1 m deep.

Detailed Explanation of Key Techniques for Autumn Top Grafting and Variety Change in Pear Trees
Grafting time. In production, large-scale top grafting of pear trees to switch to improved varieties is generally carried out from early August to late September in autumn, that is, during the period after summer shoots stop growing and before autumn shoots stop growing. During this period, the grafting survival rate is high, the cost is low, and the effect is good; usually only one year is needed.

How to Achieve High Yields After Top-Grafting Pear Trees? Master These Six Techniques
As the fruit market gradually becomes saturated, some old varieties face being phased out, and replacing the old with the new and introducing and top-grafting superior varieties is imperative. The top-grafting and its key technical points are as follows: Master the best grafting time. Late February to early March each year is the best grafting window; too early makes survival difficult, while too late means the scions bud late and the branches grow slowly, so they cannot become flower-bearing branches in the same year.

How to manage pear trees after harvest? Detailed technical points
1. Clearing the orchard and pruning pear trees: After harvesting the fruit, promptly clear all kinds of weeds, dead branches, fallen leaves and fallen fruit from the orchard, and cut off the shaded branches inside the canopy and the diseased and pest-infested branches, weak branches, dry branches, overlapping branches and overly dense branches on the outside of the canopy, and gather them outside the orchard for burning, so as to reduce sources of disease

Pear Tree Spring Pest Control Methods and Technical Key Points
Pear tree spring pests and diseases include: pear fruit borer, aphids, red spider mites, pear psylla, stink bugs, leaf-mining mites and black spot disease, etc. Timing and measures of control: from early spring to before flower buds swell, clean the orchard and scrape tree bark. Lay plastic sheeting under the tree, then scrape off the raised and coarse bark on the trunk and large branches, but do not damage the new bark. For the coarse vertical bark at the branch forks, scrape carefully. Collect the scraped bark, larvae, eggs, etc. and bury them deep or burn them. Knock down dead leaves and remaining dried fruit from the tree and remove them from the orchard for destruction, then spray the whole tree once with lime sulfur mixture.

Key Techniques for Artificial Pollination in Pear Cultivation
1. Pollination tools: A brush, soft rubber, sheep's wool, etc. can be used. Place the pollen in a clean, dry small bottle. Once the tool is fully coated with pollen, it can pollinate about 10 flowers. 2. Collecting pollen: Collecting pollen is often combined with flower thinning. Pollen is generally collected from pear trees that bloom earlier and produce more pollen

Detailed Explanation of Key Points of Winter Pruning Techniques for Pear Trees
When pear trees enter dormancy, it is a great time for winter pruning. The pruning techniques for different age stages are as follows: 1. Pruning of young trees: The purpose of pruning is to shape the tree well, cultivate a good framework, promote branching, expand the canopy, promote branches, and bear fruit early. Generally, long branches are lightly pruned and left to grow slowly, upright vigorous branches are bent flat, medium and short branches are retained, and the sprouted shoots are used as much as possible to expand the canopy. Apart from thinning out some overly dense branches, thinning is generally not carried out.

Technical measures for summer management of greenhouse cherries
One, focus on summer pruning. While removing the film, promptly cut back the tree canopy and carry out heavy pruning. 1. Lower the central leader. This method can reduce the overall height of each cherry tree canopy by 50-80 cm respectively, preventing the tree from growing taller and taller and affecting ventilation and light penetration inside the greenhouse

A Complete Guide to the Key Points of Post-Harvest Management Techniques for Cherry
From after fruit harvest to leaf fall, during this period the nutrients produced by the leaves are no longer consumed by the fruit, but are used for the further differentiation and filling out of flower buds, thickening of branches and trunks, maturation of tissues and accumulation of the main nutrients. Therefore, if management during this period is good, it will not only

Detailed Explanation of Key Points of Fertilizer Spraying Technology for Cherry Cultivation
(1) Fertilizer spraying timing: Foliar fertilizer can be sprayed from after the cherry tree sprouts until before maturity, and even before leaf fall; (2) Fertilizer types: Any nutrient elements required by crops can be used as fertilizer spray types; (3) Purpose of fertilizer spraying: It is to supplement fertilizer to cherry trees through foliar spraying;
