Abstract

The tender branch planting method for goldleaf elm includes the following steps: cutting tender branch in 8-15 cm length as cutting wood in May to September, inserting the lower end of the cutting wood with naphthylacetic acid solution in 450-550 ppm concentration for 8-12 sec, planting into medium comprising vermiculite, perlite and turfy soil in the weight ratio of 1 to 0.8-1.2 to 0.8-1.2 inside an arched shed in an all-weather greenhouse, and maintaining the temperature inside the shed at 25-35deg.c and air humidity of 70-90 % for the cutting wood to grow callus in one week, root in 15 days. The said process has high planting survival rate.

Description

Tender branch planting method for gold-leaf elm

Technical field

The present invention relates to a kind of ornamental plant propagation method.Be specifically related to a kind of tender branch planting method for gold-leaf elm.

Background technology

The gold leaf elm is the ornamental plant new varieties that an ornamental value is high, the gardens purposes is quite wide of latest find in recent years.The method of American elm scion grafting gold leaf elm is usually adopted in its breeding, and quantity is few, and reproduction coefficient is low, and is time-consuming, take a lot of work, and costs an arm and a leg, and do not satisfy the demand of market to the gold leaf elm.The gold leaf Elm is in the extremely difficult seeds that take root of cuttage (high-new one, " plant asexual multiplication technology ").Gold leaf elm softwood cutting propagation technology is not appeared in the newspapers both at home and abroad as yet.

Summary of the invention

Purpose of the present invention is intended to overcome above-mentioned weak point, and a kind of gold leaf elm softwood cutting propagation method of cuttage survival rate is provided.

The object of the present invention is achieved like this: a kind of gold leaf elm softwood cutting propagation method, it is characterized in that this method comprises following processing step: 5 ~ September, clip gold leaf elm gives birth to spray then and transplants a cutting, clip cutting length 8 ~ 15cm, 2 ~ 3 leaves are stayed at every cutting top, some bundles are a wisp, then a bundle bundle cutting lower end is immersed in methyl 450 ~ 550ppm solution, processing time is that 8 ~ 12 seconds speed is dipped in, cuttage then, cutting medium prescription are vermiculite: perlite: turfy soil :=1: 0.8 ~ 1.2: 0.8 ~ 1.2, and the cuttage facility is the built-in little shed of round-the-clock green house, hide nonwoven on the little shed, to transplant a cutting and vertically insert matrix 5 ~ 7cm, 25 ~ 35 ℃ of temperature of shed, relative air humidity 70 ~ 9096, temperature surpasses more than 38 ℃, add forced ventilation, and on the nonwoven spray cooling, transplant a cutting the long callus in 1 week back, begin to take root after 15 days, left and right sides rooting rate reached more than 80% in 30 days.

The present invention satisfies the needed optimal environmental condition of plant cuttage artificially according to the specific (special) requirements of plant cuttage to environmental condition, thereby makes gold leaf elm cuttage survival rate reach 81%, has greatly advanced the penetration and promotion of gold leaf elm.

Embodiment

The present invention is a kind of gold leaf elm epicormic branch cuttage technology, and its main technique step is as follows:

One, chooses cutting

In late May ~ September, clip gold leaf elm gives birth to spray then and transplants a cutting, every long 8 ~ 15cm of cutting, and every cutting top keeps 2 ~ 3 leaves, and per 100 bundles are a bundle.

Two, cutting treatment

Methyl (NAA) 500ppm solution middling speed is immersed in a bundle bundle cutting lower end dipped in for 10 seconds, take out standby.

Three, cutting medium and facility

The cutting medium prescription is a vermiculite: perlite: turfy soil :=1: 1: 1, mix, and the slotting machine stromal thickness is 30cm, and the cuttage facility is round-the-clock greenhouse, and the built-in little shed of booth hides nonwoven one deck on the little shed.

Four, cottage method

To transplant a cutting the vertical matrix 5cm that inserts, seeding row spacing 5 * 5cm waters permeablely after inserting, spray 1000 times of liquid of carbendazim.

Five, insert the back management

25 ~ 35 ℃ of temperature of shed, relative air humidity 70 ~ 90% afternoon is noted ventilating, and on nonwoven spray cooling.Matrix see dried see wet.Use topsin, carbendazim, tpn to spray 800 ~ 1000 times of liquid weekly by turns one time.Insert the back and 1 week grew callus, first quarter moon begins to take root, and rooting rate reached more than 8096 in 30 days, can transplant hardening.

Six, hardening

Transplant with black polypots 10 * 12cm, each is 50% formulated with soil and above-mentioned matrix for matrix, adds a little composite fertilizer again.Put pot seedling under the cool canopy that full sunshine and spray is arranged, hardening is transplanted after 20 ~ 40 days down.

Embodiment:

1, mid-May then, company implements in the ecological agricultural of Jiangsu sunlight.Clip gold leaf elm gives birth to spray then and transplants a cutting, every long 12cm, and 2 on leaf is stayed at the top.

2, cutting lower end immersion NAA500ppm solution speed was dipped in 10 seconds, took out.

3, cutting medium vermiculite: perlite: turfy soil :=1: 1: 1, mix, the thick 30cm of slotting machine, facility are the built-in little shed of round-the-clock green house, hide 1 layer of nonwoven on the little shed.

4, will transplant a cutting the vertical mixed-matrix 5cm that inserts, seeding row spacing 5 * 5cm waters permeablely after inserting, spray 1000 times of liquid of carbendazim.

5, temperature of shed is 25 ~ 35 ℃, and relative air humidity 70 ~ 90% afternoon is noted ventilating, and on nonwoven spray cooling.Matrix see dried see wet.Spray medicine once (topsin, carbendazim, tpn are rotated) weekly in the future.

6,30 days rooting rates reach more than 80%, are transplanted to 10 * 12cm size polypots (matrix is soil: mixed-matrix=1: 1 adds a small amount of composite fertilizer), put pot seedling in the cool canopy lower refining seedling that full sunshine and spray is arranged 30 days, transplant down.
