Embodiment 1

[0037] A method for growing seedlings of roxburghii in vitro, comprising the steps of:

[0038] Step (1), the selection and processing of mother branch: select the robust biennial and perennial thorn pear branch as the mother branch of seedling cultivation, cut it into 15 cm long stem segments, each with 1 bud point;

[0039] Step (2), raising seedlings: wrap the lower end of the stem segment obtained in step (1) with a wet absorbent material soaked in 50mg / L indole acetic acid solution, then place it in the culture cup, and place the culture plate Or put the culture cup into a light-transmitting container, place it at room temperature, add water every other day, and keep the gauze wrapped at the lower end of the branch moist. After 15 days, more than 90% of the stems will take root and germinate to become a complete seedling; The material is cotton, filter paper or cotton gauze;

[0040] Step (3), transplanting and hardening: transplant the seedlings obtained in step (2) int...

Embodiment 2

[0048] A method for growing seedlings of roxburghii in vitro, comprising the steps of:

[0049] Step (1), the selection and processing of female branch: select the robust biennial and perennial prickly pear branch as the female branch of seedling cultivation, cut it into 20 cm long stem segments, each with 3 bud points;

[0050] Step (2), raising seedlings: wrap the lower end of the stem segment obtained in step (1) with a wet absorbent material soaked with 50mg / L of indole acetic acid solution, then place it in a culture tray, and place the culture tray Or put the culture cup into a light-transmitting container, place it at room temperature, add water every 2 days, and keep the gauze wrapped at the lower end of the branch moist. After 15 days, more than 90% of the stems will take root and germinate to become a complete seedling; The material is cotton, filter paper or cotton gauze;

[0051] Step (3), transplanting and hardening: transplant the seedlings obtained in step (2) ...

Embodiment 3

[0059] A method for growing seedlings of roxburghii in vitro, comprising the steps of:

[0060] Step (1), the selection and processing of mother branch: select the robust biennial and perennial thorn pear branch as the mother branch of seedling cultivation, cut it into 18 cm long stem segments, each with 2 bud points;

[0061] Step (2), raising seedlings: wrap the lower end of the stem segment obtained in step (1) with a wet absorbent material soaked with 50mg / L of indole acetic acid solution, then place it in a culture tray, and place the culture tray Or put the culture cup into a light-transmitting container, place it at room temperature, add water every 1.3 days, and keep the gauze wrapped at the lower end of the branch moist. After 15 days, more than 90% of the stems will take root and germinate to become a complete seedling; The material is cotton, filter paper or cotton gauze;

[0062] Step (3), transplanting and hardening: transplant the seedlings obtained in step (2) ...

Abstract

The invention particularly relates to an afforestation technique for quick, simple, convenient and efficient Rosa roxburghii ex-vivo twig culturing and stony desertification control, and belongs to the technical field of fruit tree biology. The afforestation technique has the advantages that the simplicity and convenience are realized, the implementation is easy, the cost is low, the soil pollution is avoided, and the efficiency is high; the afforestation technique is suitable for the production practices, such as Rosa roxburghii quick propagation and stony desertification control; the transplanting survival rate reaches more than 95%, the obvious effect is realized in the stony desertification control, the vegetation coverage of the controlled area is improved by 6-8%, the soil erosion modulus is reduced by 15-20%, and the ratio of stony desertification area is reduced by 10-15%; the obvious economic benefit is realized, and the good economic benefits on water and soil conservancy, vegetation restoration and the like are realized.

Description

technical field [0001] The invention belongs to the field of fruit tree biotechnology, and in particular relates to a fast, simple and efficient method for growing seedlings of Rosa roxburghii isolated branches and an afforestation technology applied to rocky desertification control. Background technique [0002] Prickly pear (Rosa roxbunghii) is a Rosaceae plant, a small wild shrub, born in sunny hillsides, valleys, roadsides and bushes at an altitude of 500-2500 meters. wild fruit. The fruit is a rare nutritious fruit with nourishing and fitness effects. The harvest period of prickly pear is less than 30 days. Rosa roxburghii has pink, red or deep red flowers from April to June, with summer flowers and autumn fruits. Most of the fruits are oblate and spherical, and the transverse diameter is generally 2-4 cm. The fruit is ripe from August to September, yellow, sometimes with a red halo. The flesh is crisp and has a strong aroma when ripe. Small fleshy thorns grow dens...
