Description
Technical field
The present invention relates to a kind of propagation method of plant, and in particular to a kind of culturing and reproducing of dahlia, belongs to agriculture
Technical field of plant propagation in industry technology.
Background technology
Dahlia, composite family, dahlia plant, perennial herb is alias Dahlia, dahlia, Japan chrysanthemum, big beautiful
Chrysanthemum, pachyrhizus.The upright multi-branched of stem, high 120~200cm.Mexico is originated in, also there is plant the country at present, is flower variety
One of most species, have and surpass 30,000 kinds.Mid-May at florescence~November.
Dahlia kind traditional cultivation method is root division method, and the method is simple, but breeding coefficient is too low, a pier root tuber
5 or so radical buds can only be typically bred, planting speed is slow, and reproductive number is low.Consumptive material is more, is but difficult to realize the scale of dahlia
Kind
The content of the invention
It is an object of the invention to provide a kind of reproduction speed is fast, the ectogenesis side for the dahlia that efficiency high, cost are low
Method.
What the present invention was realized in：
A kind of culturing and reproducing of dahlia, comprises the following steps：
Step one：Select root tuber vernalization；Germination bed is set up, compost 25cm thickness, control temperature 15-20 are laid on germination bed
DEG C, 25 DEG C of vernalization bed tempertaure, by the insertion compost that root tuber is healthy and strong, bud mouthful is good of the healthy and strong no disease and pests harm of dahlia, insertion depth
It is defined by covering rhizome junction, pours permeable, is controlled and visible after temperature and humidity, 15d bear normal bud；
Step 2：Make seedbed；Seedbed, thickness 10cm, in uniform one layer of 5cm thickness of spreading above are laid with sandy compost
Net husky, timing daily is sprayed water, and keeps seedbed humidity；
Step 3：Bear after normal bud, when normal bud grows to 3-5cm length, young shoot is broken down in dahlia root tuber, insert seedling
On bed, insertion depth about 2-3cm is poured permeable immediately；Keep seedbed bed surface without ponding, temperature control is at 25 DEG C to 28 DEG C, at any time
Carry out water spray moisturizing；About 10d or so, young shoot is taken root, and waits young shoot root to go deep into after sandy compost, can absorb supporting for compost
Point, regrowth 20d can carry out cuttage transplanting；
Step 4：Enough decomposed manures are applied in plowed soils, need to carry out furrow face according to viewing and admiring, furrow face is wide about
Dahlia seedling replanting after 60cm furrow widths 40cm will take root enters inside furrow face, pours permeable, spacing in the rows is 1m, in dahlia seedling
Bamboo pole is plugged on side, seedling bar is connected with bamboo pole, seedling stability is kept, it is anti-to fracture；
Step 5：Seedling maintenance measure is carried out according to weather, weather arid will water in time, be arranged in time after heavy rain
Water, keeps the not flooded not non-irrigated of seedling；After transplanting, growth period every 15d or so applies an inorganic fertilizer, applies time organic fertilizer by each two moon；
Pinching at any time, keeps collateral generation.
Further scheme is：
The compost laid on germination bed is fertile soil.
Further scheme is：
In step one, pour permeable, grabbed with hand after bed soil is pinched do not drip from webs but palm be it is wet be optimal.
Further scheme is：
Sandy compost is to compare 3 according to the weight of river sand, fertile soil, perlite:2:0.5 mixes.
This method changes traditional root division method, using cutting propagation method, root tuber is broken in time after sprouting new
Bud, can continue to sprout.One root tuber from traditional 5 or so radical buds of breeding, till now can breed more than 50 radical bud, greatly
The big reproductive number for improving dahlia root tuber, it is possible to achieve more massive plantation.And the dahlia that cuttage is obtained,
The field planting of more convenient landscape planting construction.
Embodiment
With reference to specific embodiment, the present invention is further illustrated.
A kind of culturing and reproducing of dahlia, comprises the following steps：
Step one：Select root tuber vernalization.Germination bed is set up, machine compost is equipped with germination bed, compost is mainly with corruption
It is main thickness in 25cm or so to grow soil, controls 15-20 DEG C of temperature, 25 DEG C of vernalization bed tempertaure, by the healthy and strong no disease and pests harm of dahlia
Root tuber inserts compost, and insertion depth is defined by covering rhizome junction, pours permeable, moisture content number grabbed with hand after bed soil is pinched not
Dripped from webs but palm be it is wet be it is optimal, control and visible after temperature and humidity, 15d bear normal bud；Suitably controlled after budding
Moisture content processed, is shown in dry rewater.
Step 2：Make seedbed.Compare 3 with the weight according to river sand, fertile soil, perlite:2:0.5 mix it is sandy
Compost, which is laid to add in seedbed, sandy seedbed, accounts for sandy Controlled Release Fertilizer of the compost weight than 0.2%, seedbed thickness
10cm, net husky rough sand using the Yangtze river basin thick net husky in uniform one layer of 5cm of spreading above, conditional one layer of liver moss of lid, often
Its timing is sprayed water, and keeps seedbed humidity
Step 3：Bear after normal bud, when normal bud grows to 3-5cm length, healthy and strong young shoot broken down in dahlia root tuber,
Insert on seedbed, gently push liver moss aside during cuttage, insertion depth about 2-3cm covers liver moss and pours permeable immediately；Keep seedbed bed
Face is optimal at 25~28 DEG C without ponding, temperature control, does not exceed 33 degrees Celsius, and water spray moisturizing is carried out at any time.About 10d is left
The right side, young shoot is taken root, and waits young shoot root to go deep into after sandy compost, can absorb the nutrient of compost, and regrowth can be carried out for 20 days
Cuttage is transplanted.
Step 4：The organic fertilizer become thoroughly decomposed is applied according to 120~150 jin every mu in plowed soils, is done according to needs are viewed and admired
Good furrow face, the wide about 60cm of furrow face, the dahlia seedling replanting after ditch 40cm will take root enters inside furrow face, pours permeable, spacing in the rows is
1m, plugs bamboo pole on dahlia seedling side, seedling bar is connected with bamboo pole, keeps seedling stability, anti-to fracture.
Step 5：Seedling maintenance measure is carried out according to weather, weather arid will water in time, be arranged in time after heavy rain
Water, keeps the not flooded not non-irrigated of seedling.After transplanting, survive and applied a nitrogenous fertilizer every 15 days of initial stage, it is double, 80 jin every mu every time.
Growth period every 15d or so applies once-combined fertilizer, 100 jin every mu every time.The each two moon, which is applied, once cake fertilizer.150 jin every mu every time
Pinching at any time, keeps collateral generation.
This method changes traditional root division method, using cutting propagation method, root tuber is broken in time after sprouting new
Bud, can continue to sprout.One root tuber from traditional 5 or so radical buds of breeding, till now can breed more than 50 radical bud, greatly
The big reproductive number for improving dahlia root tuber, it is possible to achieve more massive plantation.And the dahlia that cuttage is obtained,
The field planting of more convenient landscape planting construction.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, and above-described embodiment is only this hair
Bright preferably embodiment, embodiments of the present invention are simultaneously not restricted to the described embodiments, it should be appreciated that people in the art
Member can be designed that a lot of other modification and embodiment, and these modifications and embodiment will fall in principle disclosed in the present application
Within scope and spirit.
