Problems solved by technology

However, this method has higher requirements on the shape of the saplings, and the saplings need to be directional cultivated; before combining the tree blanks, the root system of the saplings and the side cortex of the trunk should be removed, which will cause greater damage to the saplings, increase the difficulty of survival, and the survival and cultivation time. If it is longer, it needs to be cultivated in a greenhouse, and the cultivation cost is increased; when the tree embryo is combined, the young tree is attached to the supporting stakes, and the supporting stakes are easily rotted inside the formed big tree, forming a hollow, and the tree body has low strength. The shaping adds considerable time to the

Embodiment 1

[0029] A group of 10-30 crape myrtle trees with a diameter of breast height of 3-10 cm excavated in the mountains is used as a group, and they are arranged upright in the pit to form a large tree. The root plate, main trunk, and branches can be parallel to each other, and can be close to each other horizontally. Let part of the root disk and stem manage to coincide with the cambium. When the root plate coincides with the root plate, in order to expand the contact surface, some roots that affect the close bonding can be sawed off. After a part of the cambium is connected, it can be fixed with iron nails or tied tightly with binding objects such as iron wire. The purpose is that when the plant grows, it is not easy to swell the wounded tissue that has begun to form; Or saw the cortex that is close together, the width of the sawing path is about 0.6 cm, then bundle and saw again, depending on the size of the trunk. The width of the sawn wound surface is about 1 / 3 of the thickne...

Embodiment 2

[0036]Dig an earth pit with a diameter of 2 meters and a depth of 30 cm on the ground, and fix a wooden stake in the middle of the earth pit as an upright support for the newly combined tree, and then choose a 3-5 cm diameter and about 2.5 meters high tree collected from the wild. 5 small crape myrtle trees, tied around the core pile. Use a knife to peel off the bark that connects the trunk to the trunk, and nail it with iron nails to form a large tree embryo with a breast diameter of about 20 cm and a bust of about 70 cm. 10 small trees with a DBH of 2-4 cm and a height of 1.5-2 meters were combined on the periphery, and most of the trees were bent outwards and tied outside the first layer. At the beginning, the bonding surface was very little, accounting for about 1-2% of the side area of ​​the stem and root. In order to expand the bonding surface, peel the skin with a knife or saw off the raised bonding part with a chainsaw, and pass it three times (some only once) , what ...

Abstract

The invention discloses a cultivation method which combines a small tree into a tree with large trunk diameter and comprises following steps: A. selecting 10 to 30 small trees with DBH of 3 to 10 centimeters, keeping the coiled root and the trunk of each small tree close to each other correspondingly, and combing and fixing the small trees into a big tree embryo; B. putting the big tree embryo vertically into a tree pit and filling the soil back, consolidating the soil and watering until the soil is permeant, surrounding the periphery of the trunk of the big tree embryo with a cylinder body, filling the soil into the cylinder body, and watering for preserving moisture; C. removing the cylinder body and the soil from the periphery of the trunk, keeping consistent fertilization with dilute fertilizer, pruning deadwood or verminous branches and leading the small trees to grow into a combined body which is a tree with big trunk diameter. The invention has no requirements to the shape of small trees, does not need to remove fibril, can implement the combination with tree barks, has convenient maintenance and easy tree survival and does not need curing in plastic tents; furthermore, the invention can shorten the survival and growth period of the big tree by adding the soil into the cylinder body, and the cultivation cost is very low. The method is simple and applicable for extensive tree species, has high survival rate, quick growth and shorter cultivation period, and acquires the big tree with a solid core after growing up which has long natural survival time; the method is especially applicable for the projects of city virescence and gardening landscape.

Description

technical field [0001] The invention relates to a method for cultivating trees, in particular to a method for cultivating trees with large trunk diameters by combining small trees. Background technique [0002] Chinese patent publication number: CN 1802900A, publication date: on July 19th, 2006, title of invention " tree combination cultivation method ", has proposed a kind of combination cultivation method that can cultivate bigger trunk diameter trees in a short period of time. It includes directional cultivation of saplings, combined cultivation pre-treatment, combined tree germ, and combined cultivation process of large trees. The cultivation time is short, manpower and maintenance costs are saved, and the growth effect is good. However, this method has higher requirements on the shape of the saplings, and the saplings need to be directional cultivated; before combining the tree blanks, the root system of the saplings and the side cortex of the trunk should be removed, w...
