Abstract

The invention discloses a cutting propagation method of osmanthus trees. The cutting propagation method mainly comprises the following steps: 1), seedling bed preparation; 2), cuttings treatment; 3), cutting; 4), management after cutting. The cutting propagation method disclosed by the invention is conductive to rooting and sprouting of cuttings, and the propagation survival rate reaches over 98 percent; the land utilization rate of cutting propagation is high, the cutting propagation method is easy to master, the seedling survival rate is high, and the excellent characteristics of seed tree varieties can be kept. The cutting propagation method is applicable to large-scale commercial production of nursery stocks.

Description

A kind of osmanthus fragrans tree cuttage propagation method

Technical field

The present invention relates to the cuttage breeding method of a kind of woody plant, particularly relate to osmanthus fragrans tree cuttage propagation method.

Background technology

Sweet osmanthus is one of large flowers of Chinese tradition ten, integrate greening, beautify, sweetening treatment view and admire the excellent Landscape Tree Species had both with practicality, sweet osmanthus clearly can dust-tight, dense can be far excessive, rate as an unsurpassed one.Especially in time midautumn, Cong Gui is in full bloom, night is quiet take turns circle when, reward osmanthus of filling a wine cup for, Chen Xiang assails the nostrils, Bracing.Chanting in colored poem at ancient Chinese, the quantity of chanting Gui Zhizuo is also rather considerable.Just deeply like by Chinese from ancient times, be regarded as traditional famous flower.

Summary of the invention

Technical problem to be solved by this invention is: the invention provides the osmanthus fragrans tree cuttage propagation method that a kind of survival rate is high, be easy to establishing in large scale.

In order to solve the problem, technical scheme of the present invention is: a kind of osmanthus fragrans tree cuttage propagation method, and its step mainly comprises:

1) seedbed prepares: sand is selected in seedbed, and bedding is high 20 ~ 25 centimetres, becomes turtleback shape, the protection of lid grass, the knot in order to avoid rain re-packs;

2) cuttings process: growth selection is vigorous, adopt fringe without the osmanthus fragrans of damage by disease and insect, the spray of clip middle and upper part raw semi-lignified then makes cuttings; Cuttings is cut into the segment of 8-10 centimeter length, top retains 2 leaves; Cuttings upper end is cut into flat mouth, and base portion is cut into inclined-plane, is bundled into wisp, then the part of base portion less than 3 ~ 4 centimetres is immersed in the methyl α-naphthyl acetate liquid of 50 ± 5 mg/litre, takes out after 1 ~ 1.5 hour;

3) cuttage: cuttings divides a cuttage by thickness grading; Spacing in the rows 5 ± 2 centimetres, line-spacing 10 ± 2 centimetres; First on slotting machine, prick hole with the peg wood thick with cuttings etc., then 6-8 centimetre, cuttings bottom is inserted in the hole, compress the soil around cuttings; Finally irrigate slotting machine with the carbendazol of dilution 8000 ~ 11000 times;

4) management after inserting: when on canopy film without the globule and bed soil is dry time, water spray is incubated; Sunshade early lid is taken off evening, and in canopy, relative moisture remains on more than 85%, and temperature controls at 20 DEG C-30 DEG C; In conjunction with water spray, sprayed carbendazim 1800 ~ 2000 times of liquid once every 5 ~ 7 days; Often loosen the soil, keep the permeability of slotting machine, prevent cuttings young root rotten because anoxic causes; Erase the rudiment of cuttings base portion in time, reduce nutrient consumption; In conjunction with water spray, spray 0.2 ± 0.1% urea solution or potassium dihydrogen phosphate solution every 8 ~ 12 days once, promote cuttings root system and young sprout growth; Spring next year removes sunshade, and transplant early summer in nursery, land for growing field crops, winter can go out garden field planting when height of seedling reaches 30-50 centimetre.

Beneficial effect of the present invention: cottage method disclosed in the present application, is conducive to rooting of cuttings, and breeding survival rate is to more than 98%; Cottage propagation land utilization rate is high, and technology is easily grasped, and seedling percent is large, and can keep the good characteristic of elite stand kind, is suitable for large-scale commodity nursery stock production.

Embodiment

A kind of osmanthus fragrans tree cuttage propagation method, its step mainly comprises:

2) cuttings process: In Middle And Lower Reaches of Changjiang River, at the beginning of 6 months, growth selection is vigorous, adopt fringe without the osmanthus fragrans of damage by disease and insect, and the spray of clip middle and upper part raw semi-lignified then makes cuttings; Cuttings is cut into the segment of 8-10 centimeter length, top retains 2 leaves; Cuttings upper end is cut into flat mouth, and base portion is cut into inclined-plane, is bundled into wisp, then the part of base portion less than 3 ~ 4 centimetres is immersed in the methyl α-naphthyl acetate liquid of 50 ± 5 mg/litre, takes out after 1 ~ 1.5 hour;

Cuttings survival rate is to more than 98%; Cottage propagation land utilization rate is high, and technology is easily grasped, and seedling percent is large, and can keep the good characteristic of elite stand kind, is suitable for large-scale commodity nursery stock production.

Claims
