How to prevent and control silver leaf disease in pear trees? Growers need to master these methods
In recent years, silver leaf disease has commonly occurred in pear trees in some areas of our city. This disease is a devastating fungal disease, and when it occurs severely, it can cause pear orchards to decline within a few years. After becoming diseased, pear trees weaken in vigor. Yield decreases, and severely diseased trees die 2-3 years later, seriously affecting pear production

What should you pay attention to when introducing pear tree varieties? Remember these four points
In recent years, in the course of agricultural structural adjustment, Haimen City, Jiangsu Province, has taken pear tree cultivation as an important lever for becoming prosperous, promoting the planting of more than 8,000 mu of high-quality pears and achieving good returns. In pear tree cultivation, variety introduction is key. According to the experience of Haimen City, pear tree introduction should

What to Do If a Pear Tree Does Not Bear Fruit? A Detailed Guide to Practical Technical Measures
1. Avoid excessive application of nitrogen fertilizer. Some farmers grow sweet potatoes between their pear trees; they grow sweet potatoes to cut the vines to feed pigs, so they frequently pour pig manure, and the pear trees grow tall and large but bloom without bearing fruit. For this type of pear tree, nitrogen fertilizer application should be stopped and phosphorus and potassium fertilizers increased; apply potassium dihydrogen phosphate by trenching at the drip line of the canopy and by spraying the canopy.

Management Methods for Pear Trees in the Late Full-Bearing Stage and the Senescent Stage
Once pear trees enter the late full-bearing stage and the senescent stage, poor management, insufficient fertilizer and water, excessive fruiting load, and worsening pests and diseases will accelerate the trees' decline and death, causing them to lose their cultivation value. I. Manifestations of pear trees in the late full-bearing stage and the senescent stage. Late full-bearing stage: yield declines year by year,

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.

The key to a high-yielding pear tree lies in good blossom-period management
1. Fertilizer and water management. When pear trees bloom, insufficient nutrients affect fruit set and the swelling of young fruit, so urea should be applied 10-20 days before flower buds break. The amount applied is generally determined by tree age, tree vigor, yield and the nutritional status of the first half of the year. Spraying a 0.20%-0.50% boric acid solution during the flowering period and after flowering can increase the fruit-setting rate.

Applying biogas fertilizer to pear trees works well; growers may want to give it a try
Using biogas fertilizer to grow pears results in good flower bud differentiation, neat shoot sprouting, thick green leaves, uniform fruit, good glossiness and high sweetness, strengthens tree vigor, enhances the pear tree's resistance to ring rot disease and black heart disease, increases per-unit yield by 10%, and saves 50% on fertilizer investment. For young pear trees, apply once a month

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 in early spring? Sharing growing experience
Rational distribution of stored nutrients in the tree body and reducing useless consumption is one of the important techniques for promoting normal tree growth and producing high-quality fruit. During this period, measures such as bud removal and flower bud thinning can reduce useless consumption in the tree body, and this is a relatively important point in early spring management of pear trees.
