Pear tree fruit thinning method

Abstract

A pear tree fruit thinning method comprises disease and insect pest prevention and control, spraying of a fruit thinning agent and artificial thinning supplementation. A compound growth adjusting agent is added to the fruit thinning agent and has the advantages of improving the fruit thinning efficiency, plant disease resistance and fruit safety and saving labor. Early-stage disease and insect pest prevention and control are conducted on tree bodies before fruit thinning, the disease resistance capability of the tree bodies can be improved, tree body diseases caused by adverse factors such as fruit thinning agent spraying and high humidity are avoided, accordingly it is ensured that the tree bodies and fruits healthily grow after fruit thinning, the yield is controlled, and the fruit quality is improved under reasonable load quantity. By utilizing the pear tree fruit thinning method, the fruit thinning speed is 5-10 times higher than artificial fruit thinning speed, the labor number is 1/7-1/6 of the labor number for artificial fruit thinning, the fruit setting rate is obviously reduced after fruit thinning, the pear tree fruit thinning efficiency is effectively improved, effort-saving tree body and fruit management is achieved, and the existing problems of labor shortage and high labor cost are effectively solved.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, in particular to a method for thinning pear trees. Background technique [0002] Pear is a perennial tree or shrub of the Rosaceae Apple subfamily. my country is one of the birthplaces of the genus Pyrus. Most of the pears of the genus Pyrus in Asia originate in eastern Asia. Japan and Korea are also the original origins of Asian pears.

Pears are rich in B vitamins, which can protect the heart, reduce fatigue, enhance myocardial vitality, and lower blood pressure; tannic acid and other ingredients contained in pears can eliminate phlegm and relieve cough. The throat has a maintenance effect. [0004] Pear thinning is one of the key agricultura...
