Problems solved by technology

[0002] Hibiscus has a long flowering period, large flowers, and rich variations. It has various flower types and colors. Among them, the cuttings are soaked in rooting powder and then cut. It takes about 20 days to take root, and the rooting rate can only reach about 60%, which obviously reduces the efficiency of hibiscus cutting seedlings.

Embodiment 1

[0016] A hard branch cutting seedling raising method of hibiscus, comprising the following steps:

[0017] (1) Selection: In the middle and late February of spring, select 2-3 years old branches, cut the upper end horizontally, and cut the lower end obliquely, with a length of 15-20cm, to get cuttings;

[0018] (2) Soaking: Bundle the cuttings and put the lower end in the fermented liquid, soak at 4°C for 30 minutes to soak the cuttings; in the fermented liquid, add Bacillus natto to the soy milk, the amount of which is the weight of the soy milk 3%, fermented at 33°C for 2 days, added dimethazole, and stirred until completely dissolved, so that the mass concentration of dimethazole was 20 mg / L to obtain a fermentation broth;

[0019] (3) Heating: put the soaked cuttings in hot grass ash, and heat at 40°C for 2 hours to obtain heated cuttings; the hot grass ash is mixed with hibiscus branches and rice husks, and the weight of rice husks is the weight of hibiscus branches. 30%...

Embodiment 2

[0023] A hard branch cutting seedling raising method of hibiscus, comprising the following steps:

[0024] (1) Selection: In the middle and late February of spring, select 2-3 years old branches, cut the upper end horizontally, and cut the lower end obliquely, with a length of 15-20cm, to get cuttings;

[0025] (2) Soaking: Bundle the cuttings and put the lower end in the fermented liquid, soak at 6°C for 35 minutes to soak the cuttings; in the fermented liquid, add Bacillus natto to the soy milk, the amount of which is the weight of the soy milk 3.5%, fermented at 34°C for 2 days, added dimethazole, stirred until it was completely dissolved, so that the mass concentration of dimethazole was 23 mg / L, to obtain a fermentation broth;

[0026] (3) Heating: Put the soaked cuttings in hot plant ash, heat at 43°C for 2 hours to get heated cuttings; the hot plant ash is mixed with hibiscus branches and rice husks, and the weight of rice husks is the weight of hibiscus branches. 33% ...

Embodiment 3

[0030] A hard branch cutting seedling raising method of hibiscus, comprising the following steps:

[0031] (1) Selection: In the middle and late February of spring, select 2-3 years old branches, cut the upper end horizontally, and cut the lower end obliquely, with a length of 15-20cm, to get cuttings;

[0032] (2) Soaking: Bundle the cuttings and place the lower end in the fermented liquid, soak at 8°C for 40 minutes to soak the cuttings; in the fermented liquid, add Bacillus natto to the soy milk, the amount of which is the weight of the soy milk 4%, fermented at 35°C for 3 days, added dimethazole, stirred until completely dissolved, so that the mass concentration of dimethazole was 25 mg / L, to obtain a fermentation broth;

[0033] (3) Heating: put the soaked cuttings in hot plant ash, and heat at 45°C for 3 hours to obtain heated cuttings; the hot plant ash is mixed with hibiscus branches and rice husks, and the weight of rice husks is the weight of hibiscus branches. 35% ...

Abstract

The invention mainly relates to the technical field of planting and discloses a cuttage seedling raising method for hard branches of hibiscus syriacus. The method comprises the steps of selection, soaking, heating, cuttage and management; the method is simple, cuttings root 10-2 days after cuttage, the rooting rate reaches 91%, and the cuttage seedling raising efficiency of hibiscus syriacus is remarkably improved; the biennial or triennial hard branches are selected, traditional annual branches are avoided, a large quantity of nutrient components are stored in the branches, sufficient nutrient components are provided for the cuttings before rooting, the protoplasm activity of the cuttings is kept, formation and differentiation of callus tissue are promoted, and the survival time of the cuttings is shortened; the lower ends of cut cutting slips are placed in fermentation liquid and subjected to low-temperature soaking, the fermentation liquid is rich in nutrient components and enzymeswith small molecules, the enzymatic activity of the cuttings is improved, necrocytosis of wounds is avoided, formation of the callus tissue is accelerated, cutting rooting is promoted, and the survival rate is increased.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for raising hibiscus seedlings by hard branch cutting. Background technique [0002] Hibiscus has a long flowering period, large flowers, and rich variations. It has various flower types and colors. It is a very good garden ornamental tree species. It is widely planted in my country. The main propagation methods are seeding and cutting propagation. The traditional cutting process Among them, it takes about 20 days for cuttings to take root after being soaked in rooting powder, and the rooting rate can only reach about 60%, which significantly reduces the efficiency of hibiscus cutting seedlings. Contents of the invention [0003] In order to make up for the defects of the prior art, the purpose of the present invention is to provide a hibiscus hard branch cutting seedling raising method. [0004] A hard branch cutting seedling raising method of hibiscus, compri...
