A kind of Yunnan Caulis Mayteni branch cutting method
Technical field
The present invention relates to evergreen shrubs or dungarunga and breed expanding species method, relate in particular to a kind of Yunnan Caulis Mayteni branch cutting technology, this technology directly applies to rare tree species Caulis Mayteni and breeds expanding species.
Background technology
Caulis Mayteni is a kind of evergreen shrubs or dungarunga, and maytenin has the effect of directly killing cancer cell.At present, Caulis Mayteni branch cutting technology is usingd Guizhou Caulis Mayteni branch as material, carries out the cuttage and seedling culture test in the growth regulator of variable concentrations, different cutting medium and different cuttage season.Result shows: before cuttage, by 3 plant growth regulators (NAA, IAA, IBA), cutting is processed, all can improve Guizhou Caulis Mayteni survival rate, take root number and root long, wherein with 100 and the NAA of 200m ∥ L to process cuttage seeding survival rate the highest, reach respectively 89.2% and 84.5%.(biological journal > > the 3rd phase in 2012 of < < mountain farming)
Summary of the invention
The present invention is directed to the situation that current existing Yunnan Caulis Mayteni seedling-wood breeding expanding species technology antibacterial ability is low, plant percent is low (being 80% left and right), use Yunnan of the present invention Caulis Mayteni nursery stock cuttage breeding method, can strengthen antibacterial ability in the Caulis Mayteni reproductive process of Yunnan, short root vernalization ability strong, improve it and breed survival rate, reduce seedling-wood breeding cost.And there is the function of ecology, green, environmental protection.
A Yunnan Caulis Mayteni branch cutting method, comprises the following steps:
1) get Yunnan Caulis Mayteni branch, diameter reaches 0.3~1.0 centimeter of the best, and branch is cut into 12~16 centimeter length, and branch base portion is tiltedly cut to being 40~45 degree oblique angles, and branch top cuts flat, and can be convenient to distinguish end to end, and wherein, described branch band leaf is not with leaf sheath.
2) one end of branch being buried is immersed in willow bark soak and takes out after 3~5 minutes, best with spire willow bark, at once branch is inserted on the raw arenosol seedbed having flattened.
Caulis Mayteni is shrub or dungarunga, and its branch center is hollow, with willow bark water soaking, makes branch clip fully absorb moisture, keeps the prosperous power of life of branch, plays acting on of sterilization simultaneously; With willow bark water soaking, also can play and urge root, the effect of vernalization, the method replaces the chemicalses such as root-growing agent.Raw arenosol has stronger venting capability, and cuttage seedling root is easily bred, and significantly improves the survival rate of nursery stock.If raw arenosol is longer standing time, the carbendazim sterilization that can spray 600 times of liquid is stand-by.
Preferably, the preparation method of described willow bark soak is: willow bark is rushed to flesh, add in water, stir brewed, every 1kg willow bark adds clear water 3kg and soaks 24 hours, gets immersion juice, is blended into alcohol, both stir, wherein, soak juice described in every 1kg and add 5g alcohol.
Preferably, in described step 3) according to the line-spacing spacing of 2 * 2 centimetres, insert branch 1/3 to the raw arenosol seedbed having flattened.
Preferably, the described seedbed width in described step 3) is 1.0~1.2 meters, and 0.2~0.3 meter of height, to give birth to arenosol leveling.Between seedbed and surrounding drain ditch is set.
Line-spacing, spacing during the branch cutting of standard, can play ventilation, evenly be subject to the effect of light.
Preferably, after the Yunnan of step 3) Caulis Mayteni branch cutting operation completes, seedbed is irrigated to clear water, first by two ends, insertion seedbed, bamboo let two, in covering, after the film of canopy, with soil pressure is real, obturage, then cover the shade net of outer shade afterwards, the internal temperature of interior canopy remains between 25 ℃~28 ℃, humidity remains between 70%~80%, and the hot and humid fast-growing root of getting sprouts, wherein:
Described outer shade adopts the shade net that density is 75%, and canopy is high 2.5~2.8 meters, and the length and width of canopy is mutually suitable with the length and width on hidden ground; Described interior canopy adopts anti-aging plastic film to make, wide 1.0~1.2 meters, high 1.0~1.2 meters, and length is mutually suitable with the whole seedbed that its plastic film covers.
This technical scheme adopts two canopy Caulis Maytenis of booth cover hut to breed outside ensuring method, outer canopy have shelter from heat or light, windproof, thermal effect; Interior canopy can efficiently keep effective temperature, the humidity in canopy.If temperature of shed higher than 30 ℃, can be raised Nei Peng two, ventilate, temperature of shed is reduced.
The present invention has clear superiority in the operation of Yunnan Caulis Mayteni branch cutting utilization and actual effect.
1, using method is easy, makes material and obtains conveniently, and required cost is very low.
2, its technological merit is that nursery stock antibacterial ability is strong, the sturdy prosperity of root system, and seedling bud stalwartness is tall and big.
3, branch is processed material ecology, green, environmental protection.
4, plant percent is brought up to more than 95% by 80%~85% of current technology, has increased substantially the survival rate of Yunnan Caulis Mayteni branch cutting, all breeds cost and significantly reduces.
The present invention can make Yunnan Caulis Mayteni branch cutting rooting rate at 15~20 days, breeds and emerges at 12 months.
Embodiment
Below principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment 1
1, branch infuse is selected materials: spire willow bark; Alcohol; Clear water; Raw arenosol; Cuttage branch.
2, branch immersion liquid compound method: willow bark is rushed to flesh, and soaked, every 1kg willow bark adds clear water 3kg and soaks 24 hours, gets immersion juice, is blended into alcohol, and every 1kg willow bark soaks juice and adds 5g alcohol, stirs.
3, prepare in seedbed: lay seedbed, width is 1.2 meters, and 0.2 meter of height is complete in raw arenosol leveling; Between seedbed and surrounding dug drain ditch, require draining unobstructed.
4, processing method: select the Yunnan Caulis Mayteni branch of 2~3 years, be cut into that 12~16 centimeter length do not wait with leaf not with the branch of leaf sheath, branch base portion will tiltedly be cut and be 40 degree oblique angles, branch top cuts flat, so that distinguish end to end.After tiltedly cutting, oblique clip is stained with to ash wood, sealing; The one end of burying is immersed in the willow severe edema due to hypofunction of the spleen of getting ready after 3 minutes and takes out, places 10 minutes, after drying, according to the line-spacing spacing of 2 * 2 centimetres, insertion branch 1/3 on the raw arenosol seedbed having flattened.
5, the booth that branch is bred is made: outer shade, adopt the shade net that density is 75%, and canopy is high 2.5 meters, and the length and width of canopy is mutually suitable with the length and width on hidden ground.Interior canopy: adopt anti-aging plastic film to make, wide 1.2 meters, high 1.0 meters, length is mutually suitable with the whole seedbed that its plastic film covers.
