Abstract

The invention provides a rhizoma bletillae sexual propagation method, which comprises the following steps of (1) seed harvesting and storage; (2) seedling bed preparation; (3) substrate preparation; (4) seeding method and post seeding management; and (5) young seedling culture. The most proper conditions are artificially provided for rhizoma bletillae seed germination and growth, the fast growth of rhizoma bletillae young seedlings is promoted, a great number of seedlings can be planted in a short period, and the capability of producing rhizoma bletillae breeding seedling in a commercialization way is achieved. The rhizoma bletillae sexual propagation method has the characteristics that the time is short, the effect taking is fast, and the cost is low. In addition, the scaled operation can be realized, and the popularization and the application are easy.

Description

A kind of bletilla sexual reproduction method

Technical field

The invention belongs to medicinal plant artificial planting technique field, particularly relate to a kind of bletilla sexual reproduction method.

Background technology

Bletilla is that the orchid family bletilla belongs to herbaceos perennial, is national secondary endangered plant, the another name bletilla striata, purple orchid.Mainly be distributed in the areas such as the Guizhou on the south China Qinling Mountains, Hubei, Southern Shaanxi.General evergreen broad-leaved sylvan life of being born in height above sea level 100-3200 rice, during roadside thick grass or rock stitch more.Its root-like stock is in white, several connected, therefore named bletilla or white root.

Bletilla platymiscium about has six kinds, is distributed in East Asia, to Burma, China is main producing region, have four kinds, be respectively magnificent bletilla, little bletilla, bletilla and chrysanthemum bletilla, and all can be used as medicine.Bletilla is medicinal with dry tuber, there is effect of astringing to arrest bleeding, clearing heat and promoting diuresis, detumescence and promoting granulation, be widely used in the illnesss such as treatment hemoptysis, haematemesis, traumatism and bleeding, sore swollen toxin, pulmonary tuberculosis hemoptysis, ulcer haemorrhage clinically, there are very large commodity development potentiality.It is that orchid is a kind of simultaneously, is widely used as a kind of flowers again, has good ornamental value.

Summary of the invention

The present invention is the condition in order to utilize needed for bletilla seed germination and seedling growth, realizes the object of the merchandized handling of bletilla seedling, thus provides a kind of bletilla sexual reproduction method.

Solve the problems of the technologies described above adopted technical scheme to be made up of following step:

1, seed collection and storage: the mark of seed maturity, fruit colour is turned yellow green or brown by emerald green, in fruit, seed color becomes light yellow from white; When fruit does not split, fruit band carpopodium is together cut, fruit is spread out and puts in the cool, after seed is dry, puts into sealed bag, is placed in 4 DEG C of refrigerators for subsequent use;

2, seedbed prepares: with the seedbed of the wide 0.9m of brick one-tenth, long 10m, high 0.12m on the level land of spaciousness, stay the service aisle of 0.5m between seedbed, and at the bottom of bed, paving layer of plastic film antiseep, repaves the pine needle of thick layer 5cm;

3, matrix composition: by the by volume 1:1:1:1 ratio mixing of mountain soil, peat, leaf mould, perlite, add the abundant decomposed cow dung of said mixture gross weight 5%, repeatedly stir 5 times, add water and matrix is soaked, be deposited on sun-drenched concrete floor, cover with plastic foil, be exposed to the sun more than 15 days.Add 8cm in seedbed after crossing aperture 0.5cm sieve thick, hug flat matrix;

4, type of seeding and broadcast rear management: sow first 2 days, matrix in seed bed fully irrigated with clear water, covers plastic film moisturizing and prevents foreign matter from entering, waits to broadcast; Seed is taken out from fruit, put into the narrow meshed plastic casing as toothpick class, by each fruit 4 square metres amount, seed is evenly sprinkling upon stromal surface, on seedbed, after broadcasting, does the moisturizing of plastics Small plastic shed, then entirety builds the sunshade net sunshading and temperature reducing that light transmittance is 30% above whole seedbed;

5, seedling fosters: within after bletilla planting seed 20 days under the temperature condition of 20-30 DEG C, can sprout first leaflet, the Nitrogen, Phosphorus and Potassium of 0.1% is sprayed once at the cloudy day when growing second leaf after 45 days, Nitrogen, Phosphorus and Potassium content is N:P:K=15:15:15, sprayed once every 10 days later, after planting 90 days seedling remove plastic film in the cloudy day after growing to 5 leaves, can be used as planting seedlings after 30 days pseudobulb diameters when seedling after 0.5cm.

The beneficial effect of employing technique scheme is:

The present invention for providing the optimum of bletilla seed germination and growth by people, is impelled bletilla growth of seedling rapid, can produce a large amount of seedling in a short time, reach the ability of merchandized handling bletilla seedling.Time is short, instant effect, cost are low is characteristic of the present invention, and can realize scale operation, is easy to apply.

Embodiment

A kind of bletilla sexual reproduction method, embodiment repeat under, it is made up of following step:

Claims

1. A white and sexual reproduction method, characterized in that: it consists of the following steps:

1) Seed harvesting and storage: It is a sign of mature seeds, the color of the peel changes from bright green to yellow-green or brown, and the color of the seeds inside the fruit changes from white to light yellow; when the fruit is not cracked, cut off the fruit with the stalk, and put The fruit is spread out and placed in a cool place, and after the seeds are dry, put them into a sealed bag and place them in a refrigerator at 4°C for later use;

2) Seedbed preparation: build a seedbed with a width of 0.9m, a length of 10m, and a height of 0.12m on a spacious flat ground. Spread a layer of 5cm thick pine needles;

3) Substrate preparation: Mix mountain soil, peat, leaf humus and perlite in a volume ratio of 1:1:1:1, add fully decomposed cow dung of 5% of the total weight of the above mixture, turn it repeatedly 5 times, add water to make the substrate Wet, stack on the concrete floor with sufficient sunlight, cover with plastic film, and expose to the sun for more than 15 days;

After passing through a sieve with an aperture of 0.5 cm, add it to a thickness of 8 cm in the seedbed, and flatten the substrate;

4) Sowing method and post-sowing management: 2 days before sowing, fully pour the inner substrate of the seeding bed with clean water, cover with a plastic film to keep moisture and prevent foreign matter from entering, and wait for sowing; take the seeds out of the fruit and put them in a toothpick box In a plastic box with small holes, spread the seeds evenly on the surface of the substrate according to the amount of 4 square meters for each fruit.
