Key Technical Points for Early-Spring Pest and Disease Control in Peach Trees
As the early-spring weather gradually turns warm, various peach tree pests and diseases begin to revive, breed and multiply. Early-spring control of peach tree pests and diseases can effectively curb the occurrence and spread of many peach tree diseases and reduce the base population of insect pests. The occurrence and damage of the main peach tree pests and diseases are now presented

Experience in achieving high yield and high quality by covering greenhouse peaches with old film
Peach trees are light-loving fruit trees and are sensitive to light; when light is insufficient, the photosynthesis of the leaves cannot proceed normally. In places with sufficient light, flower buds are numerous and plump, and fruit quality is good; in shaded places, flower buds are shriveled and fruit quality is poor. Covering greenhouse peach trees with old film will cause

Methods for Pest and Disease Control in Cherry Trees During Winter Dormancy
Using manual and agricultural methods, clean the orchard, eliminate overwintering sources of pests and diseases, effectively eliminate harmful organisms, and reduce the overwintering population base. 1. Sweep up fallen leaves: Fallen leaves are one of the main overwintering sites for many pests and diseases, such as the pathogens of cherry brown spot disease and black ring rot, which

How to manage pear trees during the dormant period? A full explanation of practical tips
The dormant period of pear trees is generally from December of the previous year to February of the following year. During this time, pear trees are in a state of natural or forced dormancy, and most pests and diseases are also in a dormant state. Cultivation measures Through winter pruning, improve the ventilation and light conditions of the tree canopy, regulate the pear tree root system

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.

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

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.

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,

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.

How to prevent late spring cold damage during the pear tree flowering period
Spring late cold spells and frosts are very harmful to pear trees. Generally, when pear trees encounter a low temperature of -4.0°C at the bud stage or -2.3°C to -2.9°C at the flowering stage lasting more than half an hour, the flower organs will suffer freezing damage, usually manifested as poor pollination, dried and dead stigmas, and browned filaments or
