A kind of pear tree "four-arm trellis shape" tree shape and shaping method

Abstract

The invention belongs to the technical field of fruit tree cultivation and relates to a 'four-arm hedge-frame-shaped' pear tree form and a shaping method. The 'four-arm hedge-frame-shaped' pear tree form is characterized in that a pear tree is 290cm in height, four main branches are arranged on two sides of the central trunk of the pear tree in a two-layer manner, three fruiting branches are arranged on each main branch, each main branch is vertical to the central trunk, and each main branch is 100cm in length; the fruiting branches are vertical to the main branches, and the distance between every two fruiting branches is 28.57cm; the first layer of the main branches is 50cm in height, the second layer of the main branches is 170cm in height, and the first layer of the main branches and the second layer of the main branches are horizontal. The 'four-arm hedge-frame-shaped' pear tree form has the advantages that the three-dimensional fruiting of a traditional pear tree can be changed into single-side fruiting, the pear tree can sufficiently utilize illumination, ventilation performance is also increased greatly, diseases and pests can be reduced effectively, and fruit quality can be increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a "four-arm trellis-shaped" pear tree shape and a shaping method. Background technique [0002] Pear (Pyrus L.) is an important economic crop in my country, and its cultivated area and output both rank first in the world. Pear fruit has high nutritional value, crisp and juicy, sweet and sour taste, and has certain medical value, so it is loved by consumers. In the cultivation technology management of pear trees, the tree structure is directly related to the lighting efficiency and nutrient distribution of the tree body, thereby affecting the fruit quality, and it occupies a very important position in the pear tree cultivation system. At present, in the domestic pome fruit industry, labor costs have increased greatly. In the past, the large-crown tree shape and some tree shapes with high technical requirements required a long period of time, complicated...

Problems solved by technology

However, the scaffolding tree shape has the problems of long shaping time and high input cost, while the slender spindle shape still requires high cultivation and management techniques

At present, the population engaged in agricultural labor in my country is showing an aging trend. Women and men over the age of 60 have become the main force of the labor force. This part of the population has poor learning ability for cultivation techniques.
