Description
Technical field
The invention belongs to plant asexual propagation field, relate to method for cultivating seedlings, specifically a kind of Radix Calotropis giganteae high-altitude
The method of mound layering.
Background technology
Radix Calotropis giganteae (Calotropis gigantea (L.) Dry. ex Ait. f.) Shu Luo section Calotropis is upright
Shrub, has the multiple value such as fiber, medicinal, the energy.The fiber of Radix Calotropis giganteae can be used for textile manufacturing, rope making rope, papermaking,
Synthetic cotton and knit burlap, gunnysack etc., it is also possible to as potential water suction oil absorption material, heat insulating material formed and buoyant material etc..Its root,
Stem, leaf and fruit etc. are the most pharmaceutically acceptable, have antiinflammatory, antibacterial, reduce phlegm and the effect such as removing toxic substances, for leprosy, asthma, cough, ulcer
With the treatment of the diseases such as tumor, its milk rich in cardiac glycoside compounds, have heart tonifying, protect the liver, the curative effect such as easing pain and diminishing inflammation, bark
Can control insane tinea, relevant expert also also extracts the compound with antitumaous effect from Radix Calotropis giganteae.Refine from Radix Calotropis giganteae stem, leaf
The white milk gone out, contained carbon ratio is close with crude oil.Therefore, Radix Calotropis giganteae is for textile industry, biological medicine industry, bioenergy
Industry has pioneering meaning.
Radix Calotropis giganteae is many based on seminal propagation at present, but the Radix Calotropis giganteae period of maturation is inconsistent, and artificial seed collecting is wasted time and energy, and
Seminal propagation needs to experience 3 ~ 4 months and just can go out garden, furthermore the filial generation differentiation of seminal propagation is big, it is difficult to keep maternal Optimality
Shape.Normal cutting propagation propagation method is relatively big by seasonal effect, and rooting rate is unstable, and survival rate is the highest, is unfavorable for what Radix Calotropis giganteae was bred
Large-scale production and exploitation application.Therefore, it is badly in need of summing up one and has that easy to operation, reproduction speed is fast, the surrival rate of afforestation
Height, can keep the Radix Calotropis giganteae asexual reproduction method of maternal excellent economic characters simultaneously, promotes Radix Calotropis giganteae high-quality, efficient, scale
Fast-developing.
Summary of the invention
The present invention is in order to overcome above-mentioned deficiency, it is provided that a kind of easy to operation, reproduction speed is fast, the surrival rate of afforestation
Height, can keep the method that the Radix Calotropis giganteae overhead layering of maternal excellent economic characters is bred.
In order to realize foregoing invention purpose, technical scheme is as follows:
A kind of method of Radix Calotropis giganteae overhead layering breeding, it is characterised in that: include preparation and process, the height of branch selection, substrate
Manage after pneumatics bar, press strip and transplant operation in vitro, Radix Calotropis giganteae elite stand selects upright or oblique life, a diameter of 0.5～1.5cm
Healthy and strong branch, carry out band girdle, band girdle mouth wrapped up substrate A got ready, carry out managing after press strip, transplant finally by vitro
Cultivate the Radix Calotropis giganteae seedlings obtaining high-quality；Main operational steps is as follows:
(1) branch selects: in 4～Radix Calotropis giganteae growth in August animated period, and growth selection is healthy and strong, be elite stand without the Radix Calotropis giganteae of pest and disease damage；
Elite stand select upright or tiltedly life, a diameter of 0.5～1.5cm healthy and strong branch as the branch of overhead layering；
(2) preparation of substrate and process: ratio mixing for 2:1:1 by volume is made into base by fresh yellow soil, coconut palm bran, wood flour
Matter A, then disinfection, keep the suitable humidity of substrate A before press strip；
(3) overhead layering:
1. band girdle: carry out band girdle at the branch base portion 10～20cm selected with Girding cutter, band girdle width 1.0～1.5cm, then
Shave cambium layer with sharp grafting knife, avoid injuring xylem as far as possible, then dip in the root-inducing powder of upper suitable concentration with clean brush pen
Solution smears band girdle mouth；
2. wrapping: applying band girdle mouth by moistening substrate A, outside transparent plastic film packs tightly substrate A, and with jag by upper and lower
Two ends are tightened；
(4) manage after press strip: strengthen elite stand rich water quality management, keep the skin wet periodically to substrate A；
(5) transplant in vitro: when finding after long root through plastic sheeting, press strip is cut from elite stand from, release jag and plastics be thin
Film, prunes press strip, and every retains 4～5 half leaves, then transplants in equipped with in the container of substrate B, water sufficient moisture, put
Routine Management is carried out, it is thus achieved that Radix Calotropis giganteae seedlings under cool canopy.
Disinfecting described in above step (2) be with volumetric concentration 0.5～1.0% potassium permanganate solution by substrate A
Spray is drenched；Described suitable humidity is that substrate A is holding humidity agglomerating, that do not drip.
The ABT6 rooting powder solution that rooting powder solution is 100ml/L of the suitable concentration described in above step (3).
Rich water quality management described in above step (4) is timely trickle, and every strain elite stand executes conventional fertilizer 1.0～2.0kg,
Every 15d executes 1 time；Described substrate A of periodically giving keeps the skin wet as spraying 1 water every 7d to substrate A, keeps substrate A to moisten.
Substrate B described in above step (5) is that fresh yellow soil is formulated with coconut palm bran 3:1 by volume；Described
Container is the plastic nutritional cup of specification 14cm × 18cm；Described cool canopy be with the shade net of obscurity 60% put up in flakes, high
The simple canopy of 1.5 ~ 1.8m.
Relative to prior art, the present invention has the following advantages that and beneficial effect:
1, the method for the Radix Calotropis giganteae overhead layering breeding of the present invention, press strip is taken root soon, and rooting rate reaches 100%, and transplanting survival rate is up to
More than 92%, Seedling strengthens high-quality, can obtain in a short time and retain the Radix Calotropis giganteae seedlings with maternal merit；After transplanting, ratio is planted simultaneously
Sub-Seedling is yielded positive results ahead of time, may advantageously facilitate Radix Calotropis giganteae high-quality, efficient, scale fast development.
2, substrate A and substrate B of the present invention are formulated according to the physiological property of Radix Calotropis giganteae different times, the side of drawing materials
Just, be prone to preparation, easy and simple to handle, consumptive material is few, low cost；The sturdy prosperity of Radix Calotropis giganteae branch cultivated, energetic；The container cultivated
Seedling convenient management, simple to operate, convenient transportation, after transplanting, survival rate is high, and nursery stock recovers fast.
3, the method for the Radix Calotropis giganteae overhead layering breeding of the present invention, simple to operate, with low cost, is suitable for promoting, has relatively
Good economic benefit, social benefit and ecological benefits.
