Abstract

The present relates to yam (Dioscorea polystachya) germchit cuttage and quick propagation method, belonging to plant germchit propagation field. The present invention is characterized in that: selecting a stem section with a leaf of yam germchit as material. Selecting upper part tender twig cut from vigorous plant as cutting, treating and inserting its to sand bed, management etc. Cuttage and quick propagation method for yam germchit propagation can facilitate the propagation rate and germchit survival rate is high and the cost is low.

Description

Quick propagating method for dioscorea seedling through cuttage

Technical field:

The present invention relates to Chinese yam Dioscorea polystachya Turczaninow seedling cuttage rapid propagating method, platymiscium sapling multiplication technical field.

Background technology:

Chinese yam Dioscorea polystachy is the Dioscoreaceae yam, has another name called Chinese yam, and its underground stem tuber has strengthening spleen and nourishing stomach, the function of promote the production of body fluid beneficial lung, tonifying kidney and benefiting sperm, is large traditional Chinese medicine commonly used; Except that medicinal, Chinese yam also is widely used in diet.

Different cultivars and wild Chinese yam have bulbil or nothing.In the production, often utilize its stem tuber head portion-reed head with and bulbil-bulbil carry out vegetative propagation, the former is subjected to the maternal plant restricted number, reproduction coefficient is low; The latter then is subjected to bulbil and has or not and the population size restriction, and cost is higher on producing, and restrictive condition is more, has restricted the development of Chinese yam plantation and processing industry.

Through patent and literature search, do not see the open report identical with the present invention.

Summary of the invention:

The objective of the invention is to overcome the deficiency of existing Chinese yam sapling multiplication technology, set up Chinese yam Dioscorea polystachya seedling cuttage rapid propagating method.It is characterized in that the Chinese yam seedling with a leaf one stem section of Chinese yam seedling is a material, the top tender stem segments of selecting eugonic plant is as the cuttage bar, cuttage bar length is 12-15 centimetre (three internodes), shank diameter is the 2-3 millimeter, require cuttage bar bottom to wipe out unnecessary blade branch, a slice healthy leaves is only left on top, it is deducted a half vane along vertical main lobe arteries and veins direction, getting lower end 8-12 centimetre of cuttage bar puts into and handled in mobile clean water 10-15 minute, cuttage is sprayed in the sand of handling once through 0.1% carbendazim in the matrix bed, two days later, the insertion of cuttage bar is adopted in the 70% husky bed that shades, the cuttage degree of depth is 8-12 centimetre, husky bed humidity is controlled at 85-90%, and cuttage moves into after 60 days in the Seedling bag, again through being transplanted to big Tanaka in 30 days.

The present invention has expanded the application of cuttage rapid propagating method, adopts cuttage rapid propagating method to carry out the breeding of Chinese yam Dioscoreapolystachya seedling, can make its sapling multiplication speed fast, plant the shoot survival percent height, cost is low.

Specific implementation method:

The propagation steps that adopts cuttage rapid propagating method to carry out Chinese yam Dioscorea polystachya seedling is:

Embodiment one

1, select the top tender stem segments of eugonic plant as the cuttage bar, cuttage bar length is that 12 centimetres of (three internodes), shank diameters are 2 millimeters, require cuttage bar bottom to wipe out unnecessary blade branch, a slice healthy leaves is only left on top, and it is deducted a half vane along vertical main lobe arteries and veins direction;

2, the lower end of Jie Qu cuttage bar is put into mobile clean water for 8 centimetres and was handled in 10 minutes;

3, the sand in the sand bed needs to spray processing once through 0.1% carbendazim before use, two days later, the insertion of cuttage bar is adopted in the 70% husky bed that shades, the cuttage degree of depth is 8 centimetres, husky bed humidity is controlled at 85%, and cuttage moves into after 60 days in the Seedling bag, again through being transplanted to big Tanaka in 30 days.

Embodiment two

1, selects the top tender stem segments of eugonic plant as the cuttage bar, cuttage bar length is that 15 centimetres of (three internodes), shank diameters are 3 millimeters, require cuttage bar bottom to wipe out unnecessary blade branch, a slice healthy leaves is only left on top, and it is deducted a half vane along vertical main lobe arteries and veins direction.

2, the lower end of Jie Qu cuttage bar is put into mobile clean water for 12 centimetres and was handled in 15 minutes;

3, the sand in the bed needs to spray processing once through 0.1% carbendazim before use, two days later, the insertion of cuttage bar is adopted in the 70% husky bed that shades, the cuttage degree of depth is 12 centimetres, husky bed humidity is controlled at 90%, and cuttage moves into after 60 days in the Seedling bag, again through being transplanted to big Tanaka in 30 days.

Claims

1, quick propagating method for dioscorea seedling through cuttage is characterized in that a leaf one stem section with the Chinese yam seedling is the Chinese yam sapling multiplication method of material.

2, the material of Chinese yam seedling according to claim 1, it is characterized in that selecting the top tender stem segments of eugonic plant as the cuttage bar, cuttage bar length is that 12-15 centimetre of (three internodes), shank diameter are the 2-3 millimeter, require cuttage bar bottom to wipe out unnecessary blade branch, a slice healthy leaves is only left on top, and it is deducted a half vane along vertical main lobe arteries and veins direction.

3, cuttage bar according to claim 2 is characterized in that getting lower end 8-12 centimetre of cuttage bar and puts into and handled in mobile clean water 10-15 minute.

4, method for quickly breeding according to claim 1, it is characterized in that sand in the matrix bed of cuttage needs to spray through 0.1% carbendazim before use handles once, two days later, the insertion of cuttage bar is adopted in the 70% husky bed that shades, the cuttage degree of depth is 8-12 centimetre, husky bed humidity is controlled at 85-90%, moves into after cuttage 58-62 days in the Seedling bag, again through being transplanted to big Tanaka in 30 days.
