Abstract
The invention discloses a seed propagation method of rhododendron arboretum, which comprises the following steps that: 1) collecting seeds: strong plants of the rhododendron arboretum are selected, and capsules are collected from November to December every year to collect the seeds; 2) preparing a seedbed; 3) germinating and sowing: the stored seeds are spread on the surface of the seedbed after being soaked from the middle of February to the first third of March in the spring of the next year every year, and then a layer of pine needle leaves covers the seeds; 4) managing of the seedling stage: watering is carried out in a conventional way, and 50 percent of pine needle leaves are removed when the seeds begin to germinate; and after 2 to 4 leaves are outgrown, nitrogenous fertilizer with the concentration of 0.2 to 1.0 percent and potash and phosphate fertilizer with the concentration of 0.1 to 0.2 percent are applied every 10 to 30 days, until the seedling is grown to 50cm in height. Due to the adoption of the seed propagation method, the seed propagation rate of the rhododendron arboretum can reach more than 76 percent. The seed propagation method of the rhododendron arboretum has the advantages of simplicity in operation, low cost, easiness in implementation, high propagation rate and the like, and is particularly suitable for being popularized to use in the high-cold mountainous region.
Description
Technical field
the present invention relates to the seed propagation method of a kind of tree-like cuckoo, belong to gardening plant seminal propagation technical field.
Background technology
Tree-like cuckoo(
Rhododendron arboreumSmith)
, be the Ericaceae aiphyllium, high 7-14 rice, leaf heavy leather matter, the oval shape lanceolar of blade, long 6.5～16 centimetres, wide 2.2～4 centimetres, the anxious point of tip, surperficial bottle green does not have hair, and middle arteries and veins sink, lateral vein nick, back side adularescent to silvery white fine hair; Long 1～2 centimetre of petiole, cylindrical, groove is arranged above, body of gland is arranged below.Total shape umbel is given birth on the top, and 1.5～2 centimetres of inflorescence axial lengths are by fine hair; Bennet is about 0.8 centimetre, by fine hair and body of gland; Calyx is little, and 5 split, and incise on the sliver top, and the inner face base portion has 5 black nectarys, and remainder has dark point; Stamen 10, filigree base portion are dredged by white undercoat; Ovary is by white fine hair.Capsule is cylindrical, is about 3 centimetres.5～June of florescence, really 8～September of phase.Mainly being distributed in the hillside of 1700～1900 meters of height above sea level, for typical high mountain monkeyhead rhododendron leaf, is one of the main ornamental plants at hundred li cuckoo scenic spots, Guizhou.
are present, and the artificial propagation techniques of tree-like cuckoo mainly is to be main vegetative propagation with the cuttage, and traditional seminal propagation mode, its reproductive efficiency is very low, and less than 1 ‰ has seriously restricted cultivation and the cultivation of tree-like cuckoo.
Summary of the invention
the objective of the invention is to: the seed propagation method of a kind of practical, easy and simple to handle, tree-like cuckoo that reproduction rate is high is provided, thereby overcomes the deficiency of prior art.
The present invention is achieved in that the seed propagation method of a kind of tree-like cuckoo of the present invention, it is characterized in that: carry out tree-like cuckoo seminal propagation by following step:
1) seed collection
Select healthy and strong tree-like cuckoo plant, the capsule of gathering annual 11～December is directly dried capsule through the sun lights solarization or with stove fire, claps with have gentle hands to make seed break away from pericarp, collects seed, in pack into cloth bag or the paper bag, stores in aeration-drying place;
2) prepare in the seedbed
Build plastic canopy with bamboo pole, and preparing nursery bed, select natural soils as matrix, the bamboo sieve sieves, and the thick soil that particle is bigger mixes with farmyard manure, is laid at the bottom of the case of seedbed, waters by routine behind the covering fine earth on it;
3) vernalization and sowing
Next year mid-February in spring in every year to early March, the seed of storage is wrapped with cloth bag, be dipped in 40～50

Carry out vernalization under the C condition; After 7～10 days, seed and the ratio row of fine earth by 1:5～1:10 are mixed, gently be spread on the surface, seedbed, cover the pine needle of one deck 3～5 cm thicks then;
4) seedling management
Water by usual manner
, treats that seed begins to show money or valuables one carries unintentionally when germinateing, and removes 50% pine needle; When cotyledon launches fully, throw off 20～30% pine needles again, every is 0.1～0.2% nitrogenous fertilizer at a distance from 10～30 days spraying concentrations; After treating that 2～4 true leaves grow, every is that 0.2～1.0% nitrogenous fertilizer and concentration are 0.1～0.2% potassium, phosphate fertilizer at a distance from 10～30 days spraying concentrations, grows to 50 centimetres high up to seedling.
The tree-like cuckoo plant of
above-mentioned stalwartness is the living plant of sun that physically well develops, do not have damage by disease and insect, completely filled fruit, and its age of tree should be more than 20 years.
Above-mentioned nitrogenous fertilizer is urea, and said potash fertilizer is KNO

above-mentioned capsule is full ripe fruit.
above-mentioned natural soils are that local humus is abundant, loose, the good subacidity yellow earth of permeability.
above-mentioned farmyard manure is the human and animal excreta of spontaneous fermentation.
The width in
above-mentioned each seedbed is 0.8～1.2 meter, and length is 9～18 meters, and the ridge height is 15～20 centimetres, and the seedbed distance between the ridges is from 50～60 centimetres.
owing to adopted technique scheme, the present invention can effectively improve the seminal propagation rate of tree-like cuckoo.Through evidence, the present invention can make the seminal propagation rate of tree-like cuckoo reach more than 76%.Therefore, the present invention compared with prior art, simple to operate, with low cost, easy to implement, reproduction rate advantages of higher that the present invention has is particularly suitable for promoting the use of at high and cold mountain area.
Embodiment
