Pummelo low-position multi-head seeding changing and single-axle hierarchic excellent quality prolificacy technique

Abstract

The invention discloses a pummelo low-position multi-head seeding changing and single-axle hierarchic excellent quality prolificacy technique. The technique comprises the steps of firstly selecting a branch that has strong growth vigour and is in the centre as a centre axis, cutting the branch at a position of 50-100cm, extracting the tip of the branch and then culturing the branch to be a central branch, selecting 2-3 different azimuths at the lower section of the central axis, preferably the staggered branches to cut, and culturing to be a first layer of main branches, culturing the tree crowns in a single-axle hierarchic manner, directionally and artificially inducing for formation by means of bud picking, core picking and traction, deliberately maintaining the middle and short branches in the tree crowns as much as possible, and culturing to be the braches bearing fruits, and finally accelerating to bloom early and to bear more fruits. The invention uses ready limbs of a tree as skeletons, changes the seeding for multiple heads at low position and shortens the replacement cycle. The tree crown recovers quickly and bears fruits early. The invention uses a single-axle hierarchicmanner and the central branch has obvious advantages. The main branches are distributed hierarchically, and the master-slave relation is definite. The technique avoids the competition among multiple heads and accords with biological law of pummelo tree.

Description

technical field [0001] The invention relates to a fruit tree cultivation technology, in particular to a low-position multi-head replanting and uniaxial layered high-quality and high-yield technology of honey pomelo. Background technique [0002] Honey pomelo is a fruit variety in my country, but for a long time, people confuse the cultivation and management of honey pomelo with the cultivation and management of ordinary citrus trees. Due to the tall pomelo tree, it is required that the structure ratio of the backbone branches must have layers and distances in order to meet the fruiting requirements of the pomelo tree. Grapefruit trees mainly rely on the middle and lower short branches to bear fruit. In the past, grapefruit trees were mainly cluster trees, which caused the canopy branches to be slightly distributed on the same level at the top, resulting in poor development of the middle and lower short branches and failure to bear fruit. Even die due to the dry inner chambe...

Problems solved by technology

Grapefruit trees mainly rely on the middle and lower short branches to bear fruit. In the past, grapefruit trees were mainly cluster trees, which caused the canopy branches to be slightly distributed on the same level at the top, resulting in poor development of the middle and lower short branches and failure to bear fruit. It even died due to dryness and malnutrition in the inner chamber, resulting in a decrease in the number of fruiting mother branches, which directly affected the yield of pomelo.

And the prior art usually adopts high grafting and changing methods when the varieties of inferior fruit trees are carried out. , dense outside and empty inside, low output
