The embodiment of the present invention additionally provides the impact test that modes of reproduction grows Pterospermi Heterophylli.When testing, choose Pterospermi Heterophylli seed propagation and Pterospermi Heterophylli propagation by grafiting two kinds of modess of reproduction respectively.In same garden on the ground, sow 500 Pterospermi Heterophylli mature seeds and the annual sweetgum seedling of grafting 500 strain respectively, after the growth of half a year, observe and the growing state of Pterospermi Heterophylli under recording two kinds of modess of reproduction, growing state the results are shown in Table 1.
Table 1: the impact that different reproductive mode grows Pterospermi Heterophylli
| Propagation method | Survival rate/% | Plant height/cm | Leading thread/mm |
| Seed propagation | 35.8 | 15.4±2.3 | 2.5±0.5 |
| Propagation by grafiting | 85.9 | 92.6±4.7 | 13.5±2 |
Can find out from table 1, the average plant height of seed propagation is 15.4cm, and average leading thread is 2.5mm, and the average plant height of propagation by grafiting is 92cm, and average leading thread is 13.5mm, and significantly will be greater than the average plant height of seed propagation and average leading thread.Meanwhile, the survival rate of propagation by grafiting is also wanted significantly higher than the survival rate of seed propagation.Can illustrate that Pterospermi Heterophylli passes through propagation by grafiting mode thus, not only maintain maternal original excellent genetic character, again can within a short period of time, afforestation family provides a large amount of high-quality neat nursery stock.
Further, the embodiment of the present invention additionally provides the impact of different grafting methods on Pterospermi Heterophylli survival rate.The present invention have chosen 3 kinds of different grafting methods, and concrete grafting method is as follows:
(1) cut-grafting method
1. stock cuts: cut off at overhead about 5cm place by sweetgum stock, and then with the vertical mouth earnestly of cutter, the width of otch is made peace greatly the equal diameters of scion.
2. scion is cut: scion is first sealed with wax, and then 2 buds are stayed in upper end, and the inclined-plane that is about 2cm is cut in lower end, then cuts the little inclined-plane of a long 1cm overleaf.
3. engage: scion is inserted in the vertical incision of stock, large inclined-plane inwards, makes the formation layer of stock and scion both sides align.Require stock otch and scion equal diameters, while scion bevel be just in time the half of scion of pruning, the width of its wound face then equals the diameter of scion, and the formation layer of the right and left so just can be made all to align.If lack of skill both sides form layer and to upper, surely will be able to not aim at.Scion requires consolidation and the about 0.5cm that shows money or valuables one carries unintentionally when inserting otch.
4. wrap up: interface is all wrapped tight with the grafting film tape of long 30 ~ 40cm, wide 2 ~ 3cm and binds.
(2) bud grafting method
1. stock is selected: the sweetgum seedling selecting vigorous and life in 1 year without damage by disease and insect of growth, requires that distance 5 ~ 6cm place, ground, diameter are at more than 0.4cm.About 10d before bud grafting, should cut off the branch of selected stock bottom far from ground 7 ~ more than 8cm, so that operation.
2. scion is cut in choosing: scion first will be selected raw branch.Preferably from healthy and strong, high yield, without damage by disease and insect, the peripheral position of tree crown that leaf bud is full, choose the developmental branch of giving birth to then that leaf bud is full.After branch is chosen, cut off blade at once, only stay petiole.Left hand holds branch properly, the right hand holds budding knife, first selected 1 leaf bud on branch, the horizontal partial application in 0.5cm place above selected leaf bud, be about 0.8cm, the more horizontal partial application of 1 centimeters below leaf bud, then upwards prune with the xylem that cutter is close to branch from lower end crosscut place, cut upper end crosscut place always, be whittled into peltate bud sheet a---scion wide at the top and narrow at the bottom.In order to keep the humidity of scion, scion can be contained in mouth or with stupe and build.
3. stock is cut: on the north of stock far from 2 ~ 3cm place, ground, horizontal partial application, is about 1cm, the degree of depth to cut off stock cortex for degree, then from the middle partial application downward vertically of horizontal mouth, is about 1 ~ 1.2cm, be cut into "T"-shaped, then choose out stock cortex, to inject scion with budding knife bone handle.
4. grafting fringe: choose out " T " notched cut on stock with budding knife, scion is inserted in otch.During insertion, the petiole of scion will be upward.After insertion, scion upper end be made with the alignment of " T " font transverse incision, if scion is long, can cut from upper end.
5. bondage: with plastic tape or other bondage material, first from interface top is tied up, down twines gradually, and leaf bud and petiole will stay outside.
6. rear management is connect: after connecing, 3 ~ 4d will check whether grafting survives.If the petiole have gentle hands of scion light one is touched come off immediately, scion color of the leather is bud green, illustrates and takes over a job.If petiole does not fall, scion is dried up, and is exactly do not take over a job, needs benefit to connect.After surviving more than 10 day, bondage be removed, in order to avoid hinder junction growth.Anvil is cut before germination spring at Second Year.The position of cutting anvil is about 2cm above the horizontal mouth of " T " font.When scion sprouting grows to certain altitude, a pillar should be inserted aside, scion branch is strapped on pillar, make scion branch vertical growth, and can prevent from being rolled over by wind.
(3) the tender tip tears skin and is fitted together to connection
1. Root-stock selection: the sweetgum seedling selecting the vigorous and life in 3 years without damage by disease and insect of growth.
2. sweetgum stock tears skin: cut three cuttves with single-edge blade at the proper height of stock, horizontal partial application, and erect and cut two cuttves, horizontal cutter width is about 1.5cm, and perpendicular two cuttves are parallel, and width is determined depending on scion rugosity, and be a bit larger tham the rugosity of scion, the degree of depth reaches xylem.
3. cut scion: Pterospermi Heterophylli scion has 2 buds, long 2 ~ 3cm, with single-edge blade, scion is whittled into wedge shape, skewer enters face will put down.
4. scion is inserted: the scion of cutting inserted in the cortex torn.
5. tie up: up tie up with the bottom of grafting film from otch, tie up in process, guarantee that scion is not moved and do not damaged.
6. bagging moisturizing: grafting part entangled with the plastic film of suitable size, two is banded on trunk, guarantees air tight, to keep scion moistening.
7. grafting management: timing is observed grafting, as temperature is too high, takes Shading treatment, after 1 month, can select suitable weather, unpacking venting hardening, after scion progressively adapts to temperature, carries out normal management after namely separating bag.
Use above-mentioned 3 kinds of different grafting methods to breed 4 years to Pterospermi Heterophylli, the survival rate of grafting the results are shown in Table 2.
Table 2: different grafting methods is on the impact of Pterospermi Heterophylli survival rate
| Grafting method | Survival rate/% | Average annual height increament/cm |
| Bud grafting method | 53.3 | 40 |
| Cut-grafting method | 86.1 | 38 |
| The tender tip tears skin and is fitted together to connection | 30 | 35 |
| The tender tip tears skin and is fitted together to connection | 92.5 | 36.5 |
Can find out from table 2, cut-grafting method and the tender tip tear the survival rate of survival rate apparently higher than bud grafting method that skin is fitted together to connection, but the tender tip tears skin, and to be fitted together to the stability of connection low, and thus, the Pterospermi Heterophylli propagation by grafiting method selection cut-grafting method that the embodiment of the present invention provides carries out propagation by grafiting.
Further, the embodiment of the present invention is investigated the impact of grafting time on Pterospermi Heterophylli survival rate.When testing, choosing the rare seedling-wood breeding cooperative society of the new agriculture in Jing Zhou county and Forest Botanical Garden, Hunan Prov. respectively as experiment place, and in March and September, namely spring and autumn carrying out grafting.Experimental result is in table 3.
Table 3: grafting time is on the impact of Pterospermi Heterophylli survival rate
Can find out from table 3, the graft survival rate in March more than 80%, apparently higher than the graft survival rate in September.The graft survival rate of different grafting time, not only relevant to weather, the nutrient content to a great extent with scion branch and eye is relevant.Spring grafting branch eye is relatively full, and grafting procedures is not easy dehydration, and nutrient is sufficient, and thus graft survival rate is relatively high.After autumn, nutrient accumulation reduces, and is unfavorable for grafting survival.Therefore, consider from the angle of plant physiology, time the time of grafting will select trees to grow, namely cut-grafting in spring effect is best.
The embodiment of the present invention additionally provides the experiment of stock to scion growth effect.When testing, the sweetgum that have chosen 5 kinds of different stock leading threads respectively carries out grafting to Pterospermi Heterophylli, breed 60 days after grafting, observe and record the bud length of scion, the quantity of blade, the result of experiment refers to table 4, accompanying drawing 2 and accompanying drawing 3, and the letter wherein in table 4 is duncan's test result (P=0.05).
Table 4: the impact that stock size grows scion
| Stock leading thread/mm | Scion bud length/cm | Blade quantity/sheet |
| <3.0 | 1.30D | 1.23C |
| 3.0-4.0 | 1.74C | 2.24B |
| 4.0-5.0 | 2.65B | 3.33B |
| 5.0-6.0 | 3.25A | 3.81A |
| >6.0 | 3.65A | 4.17A |
Can find out from table 4, accompanying drawing 2 and accompanying drawing 3, along with the increase of stock leading thread, scion bud length and blade quantity also increase gradually, and linearly increase, and therefore, the size of stock leading thread directly affects the growth of scion significantly.The strong stock of growth potential can not only supply the nutrition of scion abundance, impels grafting to grow vigorously, and can also have influence on the shape of scion, and this experimental result is supported by grafting theory.The stock being less than 4mm due to stock leading thread is unfavorable for the growth of scion and grafting, and thus, in actual production, Pterospermi Heterophylli propagation by grafiting should select leading thread to be greater than the stock of 4mm, and height of seedling will be selected to be greater than the stock of 40cm.
Further, the embodiment of the present invention additionally provides the experiment that scion affects Pterospermi Heterophylli grafting.When testing, have chosen the scion of two kinds of ranks respectively, wherein one-level fringe bud (good bud) for eye full, the fringe bud of the thick > 5mm of scion stem; Three grades of fringe buds (difference bud) for eye poor, the thick < 3mm of scion stem, be the bud ratio once recording Pterospermi Heterophylli with 10 days after grafting, experimental result refers to accompanying drawing 4.
One-level fringe bud can start to sprout at 5d, in film, eye is full, need to needle coating by eye free growth, all sprout in 30d complete, and not full three grades of fringe buds, except sprouting except time lengthening, peak of sprouting is not concentrated, sprouting time from start to end extends, the undergrowth more bad with its postponement upgrowth situation sprouted of sprouting.Further experiment shows: when the stock that sturdy leading thread is greater than 4mm mixes good one-level fringe bud, the amount of growth of its scion 60d can be 6cm, and the stock that now small and weak leading thread is less than 4mm mixes three grades of fringe blastogenesis length less than 1cm.
Can find out from accompanying drawing 4, when cultivating identical number of days, the germination rate of one-level fringe bud is higher than the germination rate of three grades of fringe buds simultaneously, thus, preferably uses scion stem thick in the scion of 3mm in the present invention.
In the breeding management of Pterospermi Heterophylli after grafting, process of sheltering from heat or light also can have an impact to the growth of Pterospermi Heterophylli grafting, and thus, the embodiment of the present invention is investigated the impact of process on the growth of Pterospermi Heterophylli grafting of sheltering from heat or light.During experiment, select annual sweetgum bareroot seedling to be that stock carries out grafting, through the follow-up study of half a year, draw data result as shown in table 5.
Table 5: shelter from heat or light on the impact of Pterospermi Heterophylli grafting
| Plant height/cm | Leading thread/mm | |
| 70% shelters from heat or light | 36.43±2.18 | 7.86±1.57 |
| Do not shelter from heat or light | 29.64±3.26 | 5.22±2.31 |
Can find out from table 5,70% the shelter from heat or light plant height of Pterospermi Heterophylli grafting of process and leading thread is obviously greater than plant height when not sheltering from heat or light and leading thread, and this illustrates that 70% process of sheltering from heat or light is conducive to promoting the growth of Pterospermi Heterophylli grafting.Meanwhile, Pterospermi Heterophylli grafting is when full exposure, and grafting plant growing way is comparatively slow, and leaf look matt, and have the withered phenomenon of 20 ~ 30%; And when 70% shelters from heat or light, grafting growing way is good, leaf look dark green, tool gloss, and plant height and leading thread are all higher than the Pterospermi Heterophylli grafting under full exposure.It can be said that bright, Pterospermi Heterophylli is not suitable for the grafting when full exposure, when selecting ground, grafting garden, the condition of sheltering from heat or light should be selected local preferably.
By above-mentioned contrast experiment and research, the Pterospermi Heterophylli propagation by grafiting method selection sweetgum that the embodiment of the present invention provides is as stock, and the leading thread of stock is greater than 4mm, and the branch selecting eye full or bud are scion, and adopt cut-grafting method to carry out grafting in spring.Grafting after grafting adopts 70% to shelter from heat or light process when managing, also will putting bud simultaneously in time, except sprouting, noting water and fertilizer management, and then can obtain a large amount of Pterospermi Heterophylli possessing the original excellent genetic character of female parent.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
