A kind of planting method of pear tree

Abstract

The invention relates to a planting method of pear trees, in particular to a cultivating method and a shaping method of the pear trees. The cultivating method comprises the steps of digging a field planting pit, and determining the planting density and planting the pear trees in the field; the shaping method comprises the steps of setting trunks at about 80 cm of pear tree nursery stock center plants and lateral plants, making the center plants and center trunks vertically grow, making the lateral plants and the center plants grow aslant and straightly in an included angle of 60-70 degrees, and cultivating large-scale branch groups; choosing and reserving main branches; continuing to cultivate the center trunks and the main branches, making the lateral plants and the center plants keep in the included angle of 60-70 degrees, and keeping the tree vigor stable. According to the planting method of the pear trees, the occupied land is saved, the garden building cost is lowered, flower bud formation is promoted, fruit bearing is accelerated, thus fruit bearing is early, the yield is high, and the benefit is increased. Through the planting method of the pear trees, the average content of soluble solid matter in pear fruits is increased by 0.8%-1.5%, the commercial fruit rate is increased by 90% or above, the yield is increased by 10%-20%, and the method is also applicable to pear varieties with moderate growth vigor.

Description

technical field [0001] The invention relates to a pear tree planting method, in particular to a pear tree cultivation and shaping method, and belongs to the technical field of fruit tree planting. Background technique [0002] Pear tree is a perennial fruit economic forest tree, which itself has the contradiction between vegetative growth and reproductive growth. If it is not coordinated, it will cause an imbalance between growth and results, seriously affecting yield and fruit quality. In the prior art, the planting density of pear trees can be divided into 3 kinds, ordinary dense planting, the row spacing of plants is 4 meters * 5 meters, and 500 plants are planted per hectare; moderate dense planting, the row spacing of plants is 2.5-3 meters * 4 meters, each 1000-833 plants are planted per hectare; densely planted, the row spacing is 1-2 meters x 3 meters, and 3333-1667 plants are planted per hectare. [0003] The shaping of pear trees is to cultivate them into a high-q...

Problems solved by technology

More than 95% of the pear orchards are sparsely planted and large-crown trees. The trees are tall, with overlapping branches, poor ventilation and light transmission, inconvenient management, a lot of labor, and inconvenient mechanized operations. These problems generally exist, restricting the development of the pear industry
