Planting method for promoting high yield of pear trees and prolonging high-yield years of pear trees

Abstract

The invention relates to the technical field of fruit tree planting, in particular to a planting method for promoting high yield of pear trees and prolonging high-yield years of the pear trees. The method includes: when the pear trees grows to the fourth year, additionally applying bear waste liquid to roots of the pear trees for one time in middle February; after budding of the pear trees, subjecting branches of the pear trees to atomizing spray of diluted sodium hyaluronate for one time; after fruiting of the pear trees, additionally applying phosphorus-accumulating bacterium liquid for one time while performing atomizing spray of the diluted sodium hyaluronate for one time; at a fruit swelling stage, performing foliage spraying of fibrinolytic enzyme solution for one time; after fruit harvesting, additionally applying marine low-temperature alkaline protease (YS-80-122) liquid for one time. By the planting method, high-yield time of the pear trees can be shortened to the fourth year without reduction of fruit quality, high-yield years of the pear trees can be effectively prolonged, and accordingly economic income is increased for fruit growers.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a planting method for promoting high-yield pear trees and prolonging the high-yield years of pear trees. Background technique [0002] Pear tree Rosaceae is a plant of the genus Pyrus, a perennial deciduous tree fruit tree with ovate leaves and white flowers. Generally, the color of pears is golden or warm yellow on the outside, and bright white inside, tender and juicy, with a sweet taste. The core taste is slightly sour, cool and sexy. Pears are distributed in North China, Northeast China, Northwest China and the provinces along the Yangtze River Basin. Harvest when the fruit is ripe between July and September, and can be used fresh or sliced ​​and dried. Boiling water with rock sugar can treat cough. In addition, pears contain a lot of vitamin A, carotene, protein, sugar, calcium, and phosphorus. It has the effects of lowering blood pressure, clearing away heat...
