Abstract
The invention discloses an eucalyptus cloeziana grafting method. The method includes the following steps: (1), selecting a time period from the spring to the early summer as grating time; (2), selecting a rootstock of 30-40cm in height, 3-6mm in rod diameter and 10cm away from the ground; (3), selecting a scion of 3-6mm in rod diameter and 15-20cm in length and with 4-8 axillary buds, and wrapping the scion by using a medical sealing film before grafting; (4), cutting two faces of the scion to be V-shaped during grafting, cutting a notch of 2.5cm in length from the middle of a rootstock grafting position, inserting the scion into the rootstock, and using a sealing film for binding; (5), moving the rootstock into a greenhouse after grafting, and maintaining humidity to be 80% and temperature to be 26 DEG C; when new leaves grow to be half of the size of mature leaves, moving a grated seedling below a shadow net of 50% in light transmittance for cultivation, and when the new leaves grow to be in the size of the mature leaves, starting to adopt all-day illumination cultivation. By the method, grafting efficiency and survival rate can be improved.
Description
Technical field
The present invention relates to eucalyptus graft technology field, particularly a kind of Eucalyptus cloeziana grafting method.
Technical background
Rapidly, form is logical straight, satisfactory in Eucalyptus cloeziana growth.Timber yellowish-brown, hardness are high, logical straight, the even structure of texture, and saw plate function admirable, is natural noble timber, is widely used in furniture and building etc.Eucalyptus cloeziana is the desirable seeds of eucalyptus sawn timber cultivation and first-selected seeds, but elite seed is short, has had a strong impact on the sustainable development of Eucalyptus cloeziana.Facts have proved, by grafting, utilize grafting to set up Eucalyptus cloeziana seed orchard not only have the effect downgrading elite stand, and energy early flowering being solid, is the effective means and the method that solve the shortage of Eucalyptus cloeziana seed.Traditional eucalyptus crossbreeding is that the fine individual plant on seed orchard or forest land carries out, eucalyptus Seedling height is with the obvious advantage, tree height is large, carrying out in artificialpollination process, operation easier is large, dangerous high, Climatic Effects is huge, and waste time and energy, have impact on normally carrying out of eucalyptus breeding work, constrain the cultivation of eucalyptus new varieties.Therefore, be necessary very much to set up and downgrade Grafting Seed Orchard, can provide convenience for breeding work, increase work efficiency, cost-saving, shorten breeding cycle, meet the demand of market to Eucalyptus cloeziana breeding.
Summary of the invention
The object of this invention is to provide a kind of Eucalyptus cloeziana grafting method, improve grafting efficiency and survival rate, efficiently set up Eucalyptus cloeziana and downgrade seed orchard, for the production of Eucalyptus cloeziana breeding and breeding lay the first stone.
The present invention achieves the above object by the following technical solutions, and Eucalyptus cloeziana grafting method, comprises the steps:
(1) grafting time: spring is to early summer;
(2) Root-stock selection: with Eucalyptus cloeziana seedling breeding stock, select high 30 ~ 40cm, overhead the stock of bar footpath, 10cm place 3 ~ 6mm, blade during grafting on reservation stock, can keep the transmission of moisture after stock vigor and grafting, nutrient;
(3) rooting rate: bar footpath 3 ~ 6mm, 4 ~ 8 axillalry buds, length 15 ~ 20cm, without damage by disease and insect, with the fringe bar that the whole looping of the medical sealed membrane of a kind of Parafilm that applauds is pruned before grafting, only stay the position of grafting, can prevent fringe bar moisture from evaporating and ensureing its permeability like this;
(4) graft technology: first use the alcohol disinfecting grafting tool of 75%, fringe bar two sides is whittled into " V " shape, choose stock grafting position, the disconnected top of secateurs, the long otch of a 2.5cm is cut from centre with grafting knife, fringe bar is inserted stock, and both sides or the alignment of formation layer, finally bandage with sealed membrane;
(5) manage and protect after grafting: after grafting, move into green house immediately, spray facility is utilized to make booth keep humidity about 80%, temperature 26 DEG C, when young leaves grow to mature leaf large half as large time, cultivate under grafting being moved the shade net of light transmittance 50%, when young leaves grows up to mature leaf size, start to cultivate with full exposure.
The time of staying moving into green house after described grafting is 21 ~ 35 days, and the time of cultivating under grafting is moved on to shade net is 7 ~ 14 days.
Outstanding advantages of the present invention is:
(1) use new wrapping film, a kind of medical sealed membrane being named as Parafilm, this wrapping film has excellent toughness, can stretch close to double length, automatic sealing, and waterproof is damp proof, and good aqueous vapor transparent performance, significantly improves grafting efficiency and survival rate;
(2) the full looping of fringe bar sealed membrane, effectively can prevent fringe bar moisture from evaporating and ensureing its permeability, automatically can burst coating, can automatically burst wrapping film during interface Callus formation when axillalry bud is sprouted, time saving and energy saving;
(3) retain the blade on stock, the transmission of moisture after stock vigor and grafting, nutrient can be kept, improve graft survival rate.
Embodiment
Below by way of specific embodiment, technical scheme of the present invention is described further.
Embodiment 1
Determine grafting time, sowing in 6 months in advance, sowing seedling is transplanted in the wide planting bag of 10cm and cultivates, treat that stock grows to high 30 ~ 40cm, overhead can utilize during the 3 ~ 6mm of bar footpath, 10cm place.Selector footpath 3 ~ 6mm, 4 ~ 8 axillalry buds, length 15 ~ 20cm, without the fringe bar of damage by disease and insect, the fringe bar that the whole looping of the front sealed membrane of grafting is pruned, only stays the position of grafting.First use the alcohol disinfecting grafting tool of 75%, then fringe bar two sides is whittled into " V " shape, choose stock grafting position, retain the blade on stock, cut off at graft position, cut the long otch of a 2.5cm with grafting knife from centre, fringe bar is inserted stock, both sides or while formed layer alignment, with thumb and forefinger fixing grafting position, bandage from bottom to top with sealed membrane.Green house is moved into immediately after grafting, spray facility is utilized to make booth keep humidity about 80%, temperature 26 DEG C, 21 ~ 35 days booth stages, when young leaves grow to mature leaf large half as large time, cultivate under grafting being moved the shade net of light transmittance 50%, this phases-time is 7 ~ 14 days, when young leaves grows up to mature leaf size, starts to cultivate with full exposure, grafting grows rapidly under full exposure, starts to be transplanted to the wide planting bag of 20cm after 14 ~ 28 days.
