Abstract
The embodiment of the invention discloses a cutting propagation method of rhododendron rivulare. The method comprises the following steps: performing site preparation; selecting and scissoring cuttings; treating the cuttings; performing cuttage and cuttage post-management. Specifically, the method comprises the following steps: selecting 3-5-year-old rhododendron rivulare as a mother plant, scissoring annual half-lignified branches as cutting materials, cutting the cutting materials into cuttings of 8-10 cm, keeping 3-4 knots for each cutting, and remaining 3-4 complete leaves at the top of the cutting; cutting a part of the top of the cutting, 0.5 cm away from a bud to be flat by a sharp edge, and cutting away a section with the length of 0.5 cm at a part of the base of the cutting, 2 cm away from the bud under the condition that the included angle between the sharp edge and the cutting is 45 degrees, wherein a cutting hole is horse-ear-shaped; cutting off 2/3 of each of the 3-4 complete leaves remained at the top of the cutting. According to the method, the difficult problems of difficult rooting and low cutting propagation rate of the rhododendron rivulare are effectively solved, the rooting rate can reach more than 82%, and the cutting rooting time is only 70 days; the method is an effective method for quickly propagating the rhododendron rivulare.
Description
Technical field
The present invention relates to a kind of plant cultivation method, more particularly, to a kind of cuttage breeding method of Rhododendron rivulare.
Background technology
Rhododendron rivulare (rhododendron rivulare hand.-mazz.) is Rhododendron in Lushan Botanical Garden, leaf papery, above deep
Green, below khaki, vein is recessed above, protrudes below, bud is coniform avette, umbel basidixed, spends many
Reach more than 10；Bennet close by short gland capillus and flat long strigose；The narrow triangle of calyx lobes, by khaki short gland capillus
And long strigose；Corolla infundibulate, aubergine, narrow cylindrical shape, filigree base portion by micro- pubescence, flower pesticide purple, close firm by rufous
Hair；The long ovoid of capsule, 4～June blooms, 7～November result.Rhododendron rivulare strong adaptability, the nice and cool moist climate of happiness is it is desirable to richness
Containing humus, loose, moistening acid ground, drought-enduring, preferably half is shady, and is referred to as the noble in Folium Rhododendri Simsii.Rhododendron rivulare is main
It is distributed in hillside shrubbery or the shaw in Hubei China, Hunan, Guangdong, Guangxi, Sichuan and Guizhou.Rhododendron rivulare is that China is precious
Dilute plant resourceses and Rhododendron simsii Planch improved seeds.The Rhododendron rivulare florescence is long, spends big and gorgeous, can enrich the many of ornamental plant species
Sample and lifting Landscape ecological city level.Meanwhile, by artificial breeding by Rhododendron rivulare from Rhododendron simsii Planch species transformation be excellent
The application of good horticultural gardening kind so far there are no promote.
At present, the research in terms of the domestic breeding in Rhododendron rivulare and reproduction technique still belongs to blank.The breeding of Rhododendron rivulare
Mainly from field directly transplanting, lack scale, systemic reproduction technique it is impossible to meet the market demand.Chinese Wild Cuculus polioephalus
Seeds of flowering plants class is various, but in addition to Rhododendron simsii Planch., can successful development and application little.Its main cause is that reproduction technique lacks.When
Before, the breeding of wild-type azalea mainly passes through seminal propagation, but has that germination rate is low, the slow problem of growth of seedling.Other
Propagation method such as propagation by grafiting workload is big, survival rate is low, technical merit has high demands, and tissue culture propagation high cost, seedling exercising survive
Rate is relatively low.It is short and the features such as breeding amount is big that cutting propagation has with low cost, easy and simple to handle, vegetative growth phase, is to be best suitable for small stream
Side Cuculus polioephalus introduce a fine variety the method bred.
Content of the invention
It is an object of the invention to overcoming the shortcomings of in existing Rhododendron rivulare reproduction technique, provide a kind of convenient, efficient, can
Scale, the cuttage breeding method of industrialization production Rhododendron rivulare, improve the reproductive efficiency of Rhododendron rivulare, increasing to meet
The market demand.
In the embodiment of the present invention provide a kind of Rhododendron rivulare cuttage breeding method, including following steps:
(1) Farm Planning: select open flat, the convenient field of draining to be bed, bedside 1.2～1.5m, dose is every
Mu 3.5kg, applies ferrous sulfate, leveling；Then tile fertile soil, compacting, and thickness is 2cm；Repave one layer sieve, size
Fresh loess for 0.2～0.3mm, thickness is 2～3cm；Using carbendazim [n- (2- benzimidazole base)-methyl carbamate]
500 times of aqueous solutions seedbed is carried out disinfection sterilization processing；
(2) selection of cutting and clip: choose 3～5 years raw Rhododendron rivulare plant as maternal plant, in 7～October, clip is worked as
The semi-lignified branch of year life is cutting material, described cutting material is cut into the cutting of 8～10cm, and every root cutting keeps 3～4
Individual section, top retains 3～4 intact leafs；
(3) process of cutting: rapped at the 1/3 of branch base portion with shears, it is 150mg/l that cutting base portion is immersed in concentration
No. 6 root-growing agents (ggr) of double gills in 1 hour, natural air drying afterwards；
(4) cuttage: the 1st leaf of cutting base portion in the substrate described in the cutting processing inserting step (1), will be made from base
Matter surface 2cm ± 0.2cm；
(5) manage after cuttage:
A. water supply in media and ambient humidity: irrigate slotting machine atomized water spray with clear water after cuttage, and using water spray film mulching method
Carry out follow-up water management, shed plastic sheeting is covered on slotting machine；
During taking root, keep relative humidity 80%～90% in canopy；
B. illumination and temperature: by adding a cover sunshade net above shed, realize different lighting requirements；When temperature is more than 35 DEG C
When, sunshade rate is 95%；When 20～35 DEG C, sunshade rate is 70% to temperature；Temperature below 20 DEG C, without sunshade net；Sooner or later,
Cloudy day, rainy day do not need sunshade；
At the cuttage initial stage, optimum temperature is 20～28 DEG C, and sunshade rate is 30%～50%；When temperature is higher than 28 DEG C, adopt
Water spray film mulching method cooling, during morning 10, afternoon 16 when water spray；
The phase temperature of taking root is maintained at 25～30 DEG C, and sunshade rate is 50%；
C. the prevention and control of plant diseases, pest control: after cuttage every 10 days with thiophanate methyl [1,2- bis- (3- carbometoxyl -2- ghiourea group) benzene]
1000～1200 times of wettable powder and 500 times of aqueous solutions of carbendazim [n- (2- benzimidazole base)-methyl carbamate] replace
Using insect-pest.
Preferably, the cuttage breeding method of Rhododendron rivulare, the scissors manner of cutting described in step (2) is by institute with sharp sword
State cutting top to scabble at bud 0.5cm, it is in 45 degree of angles that cutting base portion sentences sharp sword with cutting away from bud 2cm, and length of pruning is
One section of 0.5cm.
Preferably, the cuttage breeding method of Rhododendron rivulare, described in described step (2), the scissors manner of cutting is by top
Every blade of the 3-4 piece intact leaf retaining all cuts 2/3.
Preferably, the cuttage breeding method of Rhododendron rivulare, the cuttage depth of cuttage described in described step (4) is 3～4cm
(2 sections).
The present invention, with respect to prior art, has the advantage that
1, present invention efficiently solves Rhododendron rivulare cuttage is difficult the difficult problem taken root, cutting propagation rate is low, is effectively increased
Rooting rate and quality of rooting, rooting rate, up to more than 82%, is one of approach of the effective Fast-propagation of Rhododendron rivulare；
2nd, present invention facilitates cutting Rapid Rooting, rooting of cuttings only needs to 70 days about, with short production cycle, low cost
Honest and clean；
3rd, operation is simple for the present invention, is the effective ways of Rhododendron rivulare scale Fast-propagation.
