Band girdling method for promoting fixed point sprouting of terminalia neotaliala Capuron trunks

A technique of terminal lobulari and girdling is applied in the field of fixed-point germination, and girdling promotes the fixed-point germination of the trunk of Terminalia lobularis, which can solve the problems of high plant density, reduce the ornamental value of garden trees, and dry up, and achieve high survival rate and high ornamental value. Value, the effect of strong plant disease resistance

Problems solved by technology

[0003] However, due to insufficient management during the growth period in some nurseries, the density between the plants is too high, causing all the middle and lower branches of the plants to dry up. It just grows a circle of capped branches on the top of the trunk, which greatly reduces the ornamental value of garden trees.
[0004] For landscaping trees mainly for horticultural ornamental purposes, girdling and promoting budding are rarely used to improve the value of ornamental use, especially the technology of girdling and promoting budding of Terminalia microphylla has not been reported in China

Embodiment 1

[0026] A method for girdling the fixed-point germination of the main trunk of Terminalia lobata, comprising the following steps:

[0027] (1) Trunking: In March, before Terminalia lobata grows new young leaves, dig up the trunk and cut it at a height of 4m (the cut is smooth, and the cut is well protected), and the remaining The diameter of the soil ball is 5.5 times the diameter of the trunk meter, the depth of the soil ball is 3 / 4 of the diameter of the soil ball, and the soil ball is wrapped with a sunshade net to protect the soil ball from loosening, and transported to the fake planting site on the same day;

[0028] (2) Girdling: Design the first girdling opening at a position 1.5m away from the tree trunk, and design a girdling opening every 80cm upwards from the first girdling opening, girdling a circle but not closing it, and keeping 2cm The long primary bark is conducive to the up and down transport of some nutrients, preventing the bark from being completely cut off ...

Embodiment 2

[0034] A method for girdling the fixed-point germination of the main trunk of Terminalia lobata, comprising the following steps:

[0035] (1) Trunking: In the first ten days of March, before Terminalia microphylla grows new young leaves, dig up the trunk and cut it at a height of 6 m (the cut is smooth, and protection work should be done at the cut), The diameter of the reserved soil ball is 6.5 times the diameter of the trunk meter, the depth of the soil ball is 3 / 4 of the diameter of the soil ball, and the soil ball is wrapped with a sunshade net to protect the soil ball from loosening, and transported to the artificial planting site on the same day ;

[0036] (2) Girdling: Design the first girdling opening at a position 1.5m away from the tree trunk, and design a girdling opening every 80cm upwards from the first girdling opening, girdling a circle but not closing it, and keeping 3cm The long primary bark is conducive to the up and down transport of some nutrients, prevent...

Embodiment 3

[0042] A method for girdling to promote fixed-point germination of Terminalia lobata trunk, comprising the following steps:

[0043] (1) Trunking: Before Terminalia lobata grows new young leaves in March, dig up the trunk and cut it at a height of 5m (the cut is smooth and protected at the cut), and the retained soil The diameter of the ball is 5.5 times the diameter of the trunk meter, the depth of the soil ball is 3 / 4 of the diameter of the soil ball, and the soil ball is wrapped with a sunshade net to protect the soil ball from loosening, and transported to the artificial planting site on the same day;

[0044] (2) Girdling: Design the first girdling opening at a position 1.5m away from the tree head, and design a girdling opening every 80cm upwards from the first girdling opening. cm long raw bark to facilitate the transport of some nutrients up and down, to prevent the bark from being completely cut off and cause the trunk to dry up and die; the peeling opening is 1 cm wi...

Abstract

The invention relates to a band girdling method for promoting fixed point sprouting of terminalia neotaliala Capuron trunks and belongs to the technical field of tree planting. The method specifically comprises the steps that 1, trunks are cut, wherein plants with soil balls are dug by adopting a tree transplanting method before new leaves of terminalia neotaliala Capuron grow out, and then trunk cutting is performed at the height of 4-6 m of the trunk; 2, band girdling is performed, a first band girdling port is designed at the position, 1.5 m away from a tree head, of each trunk, and band girdling ports are upwards designed from the first band girdling port at intervals of 80 cm; 3, temporary planting is performed, wherein the terminalia neotaliala Capuron undergoing band girdling processing on the same day is transferred into root control bags through a crane and is supported; 4, watering is performed, root fixing water is supplied enough, a rooting agent is irrigated to roots, and soil is kept wet in a later period; 5, fertilization is performed, wherein trees begin to put forth buds under the band girdling ports after 25-35 days after temporary planting, and topdressing can be performed after leaf development and ageing; 6, pests are killed, wherein thiacloprid and fenitrothion missible oil are adopted to kill cerambycidae and anomala corpulenta respectively. By adopting the method, fixed point sprouting of plants is achieved, tree crown layers are better restored, the disease resistance is strong, and the survival rate is high.

Description

technical field [0001] The invention relates to a method for fixed-point germination, in particular to a method for girdling and promoting fixed-point germination of the main trunk of Terminalia lobata with high survival rate, fast growth and high ornamental value, and belongs to the technical field of tree planting. Background technique [0002] Terminalia mantaly, also known as Terminalia mantaly, is native to tropical Africa and has been introduced to Taiwan, Guangdong, Guangxi, Hainan, Fujian, and southeastern Yunnan for cultivation in recent years. Terminalia lobata has the advantages of beautiful tree shape, resistance to diseases and insect pests, strong wind resistance, and barrenness. The branches grow layer by layer on the main trunk, with a clear sense of hierarchy and high ornamental value. It is a garden tree species and coastal tree species with great ornamental value in the southern region at present, and its demand in modern landscaping projects is increasing...
