Embodiment 1

[0022] 1.1 Selection of mother tree and circumcision to promote root

[0023] Choose a plant that grows robustly and is free from diseases and insect pests as the mother tree for reproduction. The diameter of the mother tree is 8.0-10.0cm, and the tree height is about 10.0m. The trunk length between two adjacent girth cuts is 3.0m, and the girth cut needs to go deep into the phloem, to promote root germination, each section all needs to keep a certain amount of branches and leaves, and the trunk without branches and leaves can not be used as propagation material; After the body is circumcised, it is necessary to wrap the circumcision with straw mixed with mud or humus mixed with mud to promote rooting. Use a film to fix the wrapped substrate firmly, wrap the incision for a week, and keep the moisture content of the substrate above 5%. .

[0031] 1.1 Selection of mother tree and circumcision to promote root

[0032] Choose a plant that grows robustly and is free from diseases and insect pests as the reproductive mother tree. The diameter of the mother tree is 10.0-15.0cm, and the tree height is about 12.0m. The trunk length between adjacent circumcisions is 3.5-4.0m, and the circumcision needs to go deep into the phloem to promote root germination, and each section must retain a certain amount of branches and leaves, and trunks without branches and leaves cannot be used as propagation materials; After the tree body is circumcised, it is necessary to wrap the incision with straw mixed with mud or humus mixed with mud to promote rooting, use a film to fix the wrapped substrate firmly, wrap the incision for a week, and keep the moisture content of the substrate at 5% above.

Abstract

The invention discloses a two-step rooting-promotion method for cultivating saraca asoca greening trees. According to the invention, trunks and large lateral branches of saraca asoca large trees are used as propagation materials. Girdling is carried out first for promoting rooting; and when the root system appears, the trunk is cut and inserted for promoting roots. With the method provided by the invention, saraca asoca greening trees with certain scales can be directly obtained. Compared with sowing, cutting and layering propagation methods, the method can greatly shorten the cultivation period of the saraca asoca greening tree, so that the saraca asoca greening trees with certain scales can be obtained within a relatively short time. The propagation efficiency more than 3 times the original propagation efficiency can be obtained within approximately 6-10 months, and a trunk survival rate can be higher than 95%. The survival rate of newly cultivated greening trees can be effectively ensured. The method has important significance in satisfying market demands and in popularizing the excellent garden greening tree. With the method, significant economic benefit can be obtained.

Description

technical field [0001] The invention belongs to the technical field of forest cultivation, and in particular relates to a two-step root-promoting treatment method for cultivating flame flower greening trees. Background technique [0002] Flaming flower (Saraca asoca), also known as Saraca asoca, is an evergreen tree of the genus Saraca in the Hemataceae family. The flame flower stem is upright, the branches and leaves are dense, and the leaves are large pinnate compound leaves. The flowers are large and colorful. When they are in full bloom, they look like flames in the distance, so it gets its name. The flame flower has a long flowering period, majestic trees, and large and beautiful flowers. It is widely used in the main landscape of gardens, tree-lined avenues, front of houses and garden greening. In addition, the bark and leaves of the flame flower can be used as medicine, which has the effects of expelling wind and dampness, reducing swelling and pain, and diuresis. I...
