Pruning method for low-late pomelo tree

Abstract

The invention discloses a reshaping and pruning method for a low-late pomelo tree.The method comprises the steps that truck determining is performed, the tip of the upper portion of a plant is cut out from the portion, 30-40 centimeters away from the ground, of the truck of the young low-late pomelo tree, and multiple new shoots can be sprouted in the current year; in winter of the second year of planting, a central main branch which vertically and upwards grows and is located in the center of the tree crown is cut out from branches which upwards grow to enable the interior of the tree crown to be hollow; 3-4 main branches which upwards grow are retained and uniformly distributed all around, the remaining main branches which upwards grow are completely cut out, and weak branches and droopy branches are retained; the young tree can have the open-center-shaped tree crown and can fruit after being planted for 3 years, short pruning is performed on all the main branches of the low-late pomelo tree planted for 5-6 years, and excessive growing branches, internal branches and overlapping branches of all the main branches are cut out; when large lateral branches of the main branches grow to 2 meters, shortening pruning is performed.The method has the advantages that the low-late pomelo tree has the open-center-shaped tree crown and is low, compact and high in yielding ability, operation and management are convenient, time and labor are saved, the cost is lowered, and the economic benefit is extremely high.

Description

Technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a method for pruning dwarf pomelo trees. Background technique [0002] ① Conventional fruit tree pruning technology: umbrella pruning technology, with a central leading trunk (ie main trunk), which grows from the ground to the top of the tree, generally 3-5 meters high, leaving 6-8 main branches on the trunk, and the top of the tree The branches of the tree are short, and the tree looks like an umbrella from a distance after pruning, so it is called umbrella pruning technique (such as figure 1 ); Because the tree is tall and planted in a size of 4×5 meters, 33 saplings are planted per mu, and the high-yield period is late; 9-10 years of high-yield planting. ②Natural round head-shaped pruning technical plan, the fruit tree has a central leading trunk (ie main trunk), which grows from the ground to the top of the tree, generally 3-4 meters high, leaving 5-8 main...
