Abstract

The invention relates to a cutting propagation method for Euscaphis konishii, which is characterized in that, cuttings are taken from150 days to 180 days old seedlings; the length of the cutting ranges from 7cm to 10 cm, and two or three buds are reserved; the upper cut and the lower cut are flat; the distance from the upper cut to the terminal bud ranges from 0.5cm to 1.0cm; the lower cut is arranged below the leaf bud; 1/2 of the blade is cut off; the cutting is sterilized in disinfection solution for 2min; hormone is IAA; concentration ranges from 400mg/L to 450mg/L; soaking time ranges from 1.5min to 2min; substrate is formed by two portions of yellow soil and one portion of cleaned river sand; a seedbed is sterilized before cutting; cutting depth is about 1/3 of the cutting, with an angle around 60 DEG; planting spacing is 2cm x 4cm; cutting bed is cleaned after cutting; the temperature and the humidity of the cutting bed is regulated; after root is completely developed, mature organic manure is applied every week. The method has an advantage that, the objective of improved variety and strong seedlings is achieved.

Description

Euscaphis konishii cutting propagation method

Technical field

The invention belongs to the cultivation method of economic forest, particularly relate to cuttage breeding method medicinal, ornamental plants.

Background technology

Euscaphis konishii (Euscaphis konishii Hayata) is the evergreen dungarunga of the wild crow Toona of Staphyleaceae, but the seed oil soap system; Bark can be made tannin extract; Root, really warm in nature, mildly bitter flavor.Dispel rheumatism, hemostasis and pain-relieving, delivering looses trembles with fear.The radical cure puerperal fever, traumatic injury.Fruit is controlled testiclar gall, the prolapse of uterus.Euscaphis konishii has the effect of seeing flower, seeing leaf and reward fruit, ornamental value height.Fruit-growing time is long, from the late September exocarp fruit abscission in March in next year that reddens, sees fruit for up to half a year, and red gorgeous blind pod has increased many celebrating colors to autumn and winter season, makes the people intoxicated.Wild crow Chinese toon is as ornamental tree species, applied range, but mass-planting, group planting also can be used for ground setting such as flower garden, park in the lawn.But because the seed of euscaphis konishii has the characteristics of deep dormancy, from collecting seed insemination and emergence span 3 years, and emergence rate is low, the asexual reproduction method of anxious these seeds in the production, make it to remedy within a short period of time the deficiency of seed seedling-raising quantity, significant to production practices.Units such as Agricultural University Of Jiangxi have carried out cuttage breeding method research, and achievement is at " the cane exploitation of forestry section " the 21st volume the 3rd phase 71-73 page or leaf in 2007.In yellow soil matrix, average rooting rate is respectively 86.77%, possesses good practical prospect, but still does not reach more than 90%.

Summary of the invention

The method that the purpose of this invention is to provide a kind of cuttage and seedling culture reaches more than 90% rooting rate, cultivates breeding strong sprout simultaneously.

Method of the present invention realizes as follows:

Plugged ear: select the born euscaphis konishii seedling of 150-180 mid-September, the plant that select robust growth, no damage by disease and insect, has no mechanical damage.Select the branch that leaf bud is full, branch is sturdy, internode is short to make plugged ear.Long 7～the 10cm of plugged ear, each plugged ear keeps 2～3 buds, and last clip is for flat mouthful, and apart from terminal bud 0.5～1.0cm, following clip also is flat mouthful, and following clip is below the internode place or below the leaf bud; Cut off 1/2 of blade, 2min. sterilizes in thimerosal

Hormone and processing time: hormone is IAA, and concentration 400-450mg/L, soak time are 1.5-2min.

Slotting machine: adopting 2 parts of yellow soils to add 1 part of clean river sand is matrix, and the leveling slotting machine carries out disinfection to the seedbed then before the cuttage, and liquid to be sterilized sees through matrix cuttage again.

Cuttage: adopt with adopting with inserting; The cuttage degree of depth is about 1/3 of fringe bar, about angle 60 degree, cuttage seeding row spacing 2cm * 4cm, after the cuttage around the compacting plugged ear, water after cuttage finishes 1 time permeable.Take the plastic film shed then, salable increase seedling bed temperature and humidity.

Insert the back management: keep slotting machine cleaning and humidity, execute organic thin fertilizer after root development is complete weekly 1 time.

Adopt the inventive method to carry out cottage propagation, 95%, 150 day plant height 50cm of its rooting rate average out to, ground stem 0.6-1.0cm.There is the relatively problem of difficulty of deep-sleep, seminal propagation in the seed that has overcome euscaphis konishii well, and survival rate is than higher, and growing way, form after surviving are good.

The invention will be further described below in conjunction with embodiment.

Specific embodiment

Embodiment 1:

Plugged ear: select 170 born euscaphis konishii seedling mid-September, the plant that select robust growth, no damage by disease and insect, has no mechanical damage.Select the branch that leaf bud is full, branch is sturdy, internode is short to make plugged ear.The long 7cm of plugged ear, each plugged ear keeps 2 buds, and last clip is for flat mouthful, and apart from terminal bud 0.5～1.0cm, following clip also is flat mouthful, and clip cuts off 1/2 of blade below internode place or leaf bud, and 2min. sterilizes in thimerosal

Insert the back management: keep slotting machine humidity and cleaning, execute organic thin fertilizer after root development is complete weekly 1 time, as rare night soil that becomes thoroughly decomposed.

Its rooting rate reaches 96%, 150 day plant height 52cm, ground stem 0.8-1.0cm.
