2nd, scion process: adopting the fringe time should control at resin flow progresses row.The peripheral branch of clip tree crown middle and upper part, and live body chilling treatment immediately, stand-by.
3rd, grafting operation:
1., grafting period: after selecting resin flowing, tree be in physiological growth activity vigorous period；
2., stock process: all being removed its needle along the needle direction of growth in the range of the 2-3cm below its terminal bud by stock, then being reamed terminal bud by its base portion, cut from medulla central authorities downwards from its section, notch depth is 1.5-2.0cm.
3., scion process: the scion chosen also is plucked needle by upper method, cut from the position of downward about the 2cm in bastem portion, with cutter by the both sides down-cutting of terminal bud base portion, cut into thin, the relative stem side in a stem side thicker wealthy, form the shape to wedgewise, lower end wedgewise for the stem.
4., bonding operation: select rugosity be stock rugosity 2/3rds to etc. thick scion coordinate grafting.Inserting scion in stock otch, the formation layer of its wealthy portion stem side and stock form that layer is relative and abundant laminating gapless, and scion is inserted stock notch depth and do not stayed with scion tool marks to be limited, and is wrapped up fastening at grafting by wrapper material, does not stay knife wound to be limited.
Conifer plant grafting method technical scheme provided by the present invention, is a kind of pine tree bud-end wedge joint technology, and it has simple to operate, be easy to grasp, skilled after can realize the grafting workload of 150 strains for each person every day, survival rate is high, more than 90% can be reached, and average increment is high.
Detailed description of the invention
