Description

Dracaena cochinchinensis seeding and cultivating method

Technical field:

The present invention relates to a kind of Dracaena cochinchinensis seeding and cultivating method, platymiscium culture technique field.

Background technology:

Dragon's blood exhausts the resin that the fat xylem is processed into through extraction that contains for liliaceous plant swordleaf dragon tree Dranaena cochinchinensis (Lour.) S.C.Chen, be conventional Chinese medicine, promoting blood circulation to remove blood stasis is arranged, the analgesic therapy hemostasis, effects such as expelling pus and promoting granulation are mainly used in traumatic injury, hemostasis is had a pain, women's qi and blood stagnation, traumatism and bleeding, running sore does not close up for a long time.

At present, swordleaf dragon tree is a natural plants, does not have manually cultivation.And natural swordleaf dragon tree forms that can to gather the cycle that dragon's blood exhausts longer, and is comparatively in short supply to making dragon's blood exhaust raw material.

By literature search, do not see the open report identical with the present invention.

Summary of the invention:

The object of the present invention is to provide easy, the high a kind of Dracaena cochinchinensis seeding and cultivating method of kind shoot survival percent.

The present invention is achieved in that

A kind of Dracaena cochinchinensis seeding and cultivating method comprises seed collection, the making of husky bed, seed treatment and sowing and seed cultivation step, wherein:

A. seed collection:: select the 8-10 month, harvest maturity is at the orange red or red natural seed 90% or more, and the seed of gathering places shady and cool ventilation airing after removing the peel;

B. husky bed is made: select the physical features drying, leeward on the sunny side, the water source is local easily, by wide 1 meter, long 5 meters specification is made, husky bed is all around with brick high 20 centimeters, hole in smooth, put into river sand after the layer of plastic film of shop, placing thickness is the 15-18 centimetre, and irrigates husky bed sterilization with the liquor potassic permanganate of 0.5% concentration;

C. seed treatment and sowing: the naphthalene acid solution with 0.5% before the sowing was soaked seed 2 hours, or with after 30 ℃ of water seed soaking 2-12 hours, the seeding quantity of seed by every square of 200-250g fitly is laid on the husky bed, on the good seed of discharging, cover the disappeared river sand of poison of 1-1.5 centimetre, and water permeablely, cover one deck straw subsequently again and build shed covered with plastic film and shading screen;

D. seed cultivation: after planting,, broadcast the back and emerged in 28-30 days according to weather condition and the decision of the husky bed humidity number of times that waters, the every square of 600-800 strain of emerging, emergence rate is 30-35%; In time move in the nutritious bag that nutrition soil is housed in it it stand-by after emerging; The nutritious bag specification is 14 * 16 centimetres, and nutritive soil preparation is: get smoulder soil 4 parts, 6 parts of mixing of mountain forest humus soil, add the fused calcium magnesium phosphate of its value for become thoroughly decomposed sheep excrement and 0.1% of composite soil weight 10% simultaneously.Seedling after the pack is pressed wide 1 meter, long 10 meters proper alignment, 0.5 meter of seedbed spacing.

And construction shed covered with plastic film and shading screen.

That the present invention has is easy and simple to handle, go out the shoot survival percent advantages of higher.

Embodiment:

1, seed collection and storage

In the 8-10 month, harvest maturity is at the natural seed more than 90%, and main criterion is to observe the fruit appearance color, changed into by dark green or lavender and can pluck when orange red or red.After the seed peeling of gathering, place shady and cool ventilation airing, packing into behind the airing has in the cloth bag of gas permeability, places under the shady and cool condition of ventilating to preserve, and also can promptly adopt promptly and broadcast.

2, husky bed is made: select the physical features drying, leeward on the sunny side, the water source is local easily, by wide 1 meter, the specification of long 5 meters (length is decided according to the place), to build high 20 centimeters all around with brick, hole in smooth, put into matrix (river sand) after the layer of plastic film of shop, placing thickness is the 15-18 centimetre, and irrigates sterilization with the liquor potassic permanganate of 0.5% concentration.If untimely sowing drenches with rain for preventing, add a cover film.

3, seed treatment and sowing: soaked seed 2 hours with 0.5% naphthalene acid solution before the sowing or with after 30 ℃ of water seed soaking 2-12 hours, the seeding quantity of seed by every square of 200-250g fitly is laid on the husky bed, on the good seed of discharging, cover the disappeared river sand of poison of 1-1.5 centimetre, and water permeablely, cover one deck straw subsequently again and build shed covered with plastic film and shading screen.

4, seed cultivation: after planting, determine to water number of times, broadcast the back and emerged in 28-30 days according to weather condition and husky bed humidity, the every square of 600-800 strain of emerging, emergence rate is 30-35%.In time move in the nutritious bag that nutrition soil is housed in it it stand-by after emerging.The nutritious bag specification is 14 * 16 centimetres.Nutritive soil preparation is: get smoulder soil 4 parts, 6 parts of mixing of mountain forest humus soil, add the fused calcium magnesium phosphate of its value for become thoroughly decomposed sheep excrement and 0.1% of composite soil weight 10% simultaneously.Seedling after the pack is pressed wide 1 meter, long 10 meters (length is decided according to the place) proper alignment, and 0.5 meter of seedbed spacing, and build shed covered with plastic film and shading screen.

The actual use show, this method is not only easy and simple to handle but also go out the shoot survival percent height.
