Description

A method of girdling to promote fixed-point germination of the main trunk of Terminalia lobata

technical field

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

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.

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. In the past, only a circle of capped branches grew on the top of the trunk, which greatly reduced the ornamental value of garden trees.

For landscaping trees mainly for horticultural ornamental purposes, girdling and promoting budding are rarely used to improve ornamental value, especially the technology of girdling and promoting budding of Terminalia microphylla has not been reported in China.

Contents of the invention

The purpose of the present invention is to provide a method for girdling and promoting fixed-point germination of the main trunk of Terminalia lobata, which has strong disease resistance, high survival rate, fast growth, fixed-point germination, and high ornamental value.

For realizing the above-mentioned purpose of the invention, the technical scheme that the present invention takes is as follows:

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

(1) Trunking: In March, before Terminalia lobata grows new leaves, dig up the trunk and cut it at a height of 4-6 m (the cut is smooth and protected at the cut) , the diameter of the reserved soil ball is 5.5-6.5 times the diameter of its trunk meter, the depth of the soil ball is basically 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 false planting site;

(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. - 3cm long raw bark to facilitate the up and down transportation of some nutrients, to prevent the bark from being completely cut off and causing the trunk to dry up and die;

(3) False planting: the day after the girdling treatment, the small-leaf Terminalia was moved into the beauty planting bag with the help of a crane, straightened to keep the tree upright, so that the soil ball was in the middle of the beauty planting bag, the sunshade net was removed, and the soil was filled in layers. Auxiliary filling with stick soil; and support according to tree specifications and height of center of gravity;

(4) Watering: After the trees are fixed and supported, the fixed root water should be watered enough to make the roots around the soil ball fully contact with the backfill soil; then the roots should be watered with a special rooting agent for false planting of trees; Just keep the soil moist; at the same time, spray water on the tree in time to keep it moist according to the weather;

(5) Fertilization: 25-35 days after the artificial planting, the trees will start to germinate under the girdling mouth; after the leaves are aged, topdressing can be carried out, and each plant is applied with about 100 grams each time. The principle of fertilization is small and frequent, and fertilization is done every month 1 time.

(6) Insecticide: Terminalia lobata has a strong ability to resist diseases and insect pests. Except for the coffee wrinkled beetle and the aeruginosa beetle, no other diseases and insect pests have been found to cause major damage to the seedling tree. The coffee wrinkled beetle and the aeruginosa beetle The insecticides used were thiacloprid and fenitrothion EC.

The girdling opening described in step (2) is 1 cm wide and goes deep into the xylem, so that the meristems between the phloem and the xylem are all exposed to lose water, and the nutrient delivery channel is cut off. same direction.

For the support mentioned in step (3), the triangular support is used to stabilize the tree body. The support point is at 2/3 of the tree height. One of the support poles is set up in the windward direction, and the other two are evenly distributed. The support material used is bamboo poles. Or fir strips; or use custom-made steel pipe brackets to support, but the cost has increased.

The special rooting agent for false planting of trees described in step (4) is used to irrigate the roots on the second day after the root-fixing water is fully poured, and then irrigate once every 10 days, and irrigate continuously for 2 to 3 times.

The water spray described in step (4) is required to be fine and uniform. Spray water once a day in the morning and afternoon at the beginning of planting. After one month, spray water once a day to provide a humid environment for the tree body.

The fertilizer described in step (5) is a compound fertilizer with relatively high content of phosphorus and potassium.

The killing method of the coffee beetle beetle described in the step (6) is as follows: kill the adults with 3% thiacloprid, and if they are larvae, punch holes in the trunk and directly infuse the insect nematode.

The killing method of the aeruginosa aeruginosa described in the step (6) is as follows: during the adult stage, 50% fenitrothion EC is used, and the tree crown is sprayed; the adults lurking in the soil are sprayed in the topsoil tree tray, Shallow hoe into the soil after application.

The beneficial effects of the present invention are:

(1) This method can be used to germinate at fixed points, the recovery period is short, the plants have strong disease resistance, high survival rate, fast growth, and have high ornamental value.

(2) The method is simple, feasible, low-cost, and suitable for industrialization.
