Problems solved by technology

Acta Ecological Sinica, 1997, Volume 17, No. 6, Page 671-676, Huang Zhongliang and others conducted a 3-year experiment on the cuttings of Gemu branch. The formation of wound tissue; no viable plants were found in the ring branch and layering propagation experiments, indicating that the vegetative propagation of the tree is extremely difficult. So far, no one has made new progress in the research on the cutting propagation technology of the tree

Embodiment 1

[0027] Select annual high-quality seedlings with a seedling height of 30-40cm, a ground diameter of 5-8mm, good terminal buds, and no pests and diseases, and transplant them into a container cup of 16cm×18cm. The weight ratio is 25:69:4 and the well-stirred mother plant cultivation substrate I fills up the container cup. According to 12 container cups one row, 80 rows and one furrow are arranged tightly, and the roots are drenched with water to establish the ear picking garden. On the second day of planting, spray the mother plant with a content of 0.6% sodium o-nitrophenolate, 0.9% sodium p-nitrophenolate, 0.3% sodium 5-nitro-o-methoxyphenol, and the rest is water. Hormone compound sodium nitrophenolate; 15 days after planting, use sharp shears to cut the top to promote germination. When cutting the top to promote germination, keep 2 to 3 feather leaves from the base, and use sharp scissors to completely cut off the upper part. After collecting the cuttings each time, immed...

When cutting the top to promote germination, keep 2 to 3 feather leaves from the base, and use sharp shears to completely cut off the upper part. After each collection of cuttings, im...

Embodiment 3

[0031] Select annual high-quality seedlings with a seedling height of 30-40cm, a ground diameter of 5-8mm, good terminal buds, and no pests and diseases, and transplant them into a container cup of 16cm×18cm. The weight ratio is 23:73:6 and the evenly stirred mother plant cultivation substrate I fills up the container cup. According to 12 container cups one row, 80 rows and one furrow are arranged tightly, and the roots are drenched with water to establish the ear picking garden. On the second day of planting, spray the mother plant with a content of 0.6% sodium o-nitrophenolate, 0.9% sodium p-nitrophenolate, 0.3% sodium 5-nitro-o-methoxyphenol, and the rest is water. Growth hormone compound sodium nitrophenolate. After 17 days of planting, use sharp scissors to cut the top to promote germination. When cutting the top to promote germination, keep 2 to 3 feather leaves from the base, and use sharp shears to completely cut off the upper part. After each collection of cuttings,...

Abstract

The invention discloses an erythrophloeum fordii cutting propagation method which includes the procedures of stock plant selection, cutting orchard building, stock plant management, cutting slip picking, cutting and post-cutting management. Excellent robust nursery plants free of pest diseases are selected as stock plants and are densely arranged in a rectangular piece to build a cutting orchard, top cutting is conducted to promote sprouting, twigs or semi wood is selected as cutting scions which are inserted in container cups filled with substrates, and cutting seedlings are cultured to obtain excellent robust erythrophloeum fordii cutting seedlings. The method solves the problem that erythrophloeum fordii is difficult in vegetative propagation, has the advantages of being free of geographic limitation, high in propagation speed, simple, easy to operate, high in survival rate and the like, maintains good hereditary character of the erythrophloeum fordii, has great significance on protection and expansion of propagation and planting of the erythrophloeum fordii and has good economical benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a cutting propagation method of trellis. Background technique [0002] Grid ( Erythrophleum fordii Oliv ) Also known as Chiyemu, Dou Dengfeng, Gufen Chai, is a hematoxylin family ( Caesalpiniaceae ) Gemu is an evergreen tall tree, mainly distributed in Guangdong, Guangxi, Zhejiang, Fujian and Taiwan provinces, and distributed in low hilly areas below 800m, it is an important component of subtropical evergreen broad-leaved forest. Gemu is a precious timber tree species with high economic value. Its wood is odorless, straight in texture, fine and solid in structure. After thousands of years of immortality, it is as hard as iron with a specific gravity of 0.67. It has no shrinkage after drying, so it is called iron wood. , it is corrosion-resistant and moisture-resistant, and is mainly used in the production of high-end furniture and handicrafts. Gemu is an evergreen tre...
