Description
Technical field
The present invention relates to the scale grafting production method of gardens Woody flower, being specifically related to a kind of take Michelia chapensis as the high method connecing chrysanthemum yulan of stock, belongs to seedling ornamental plant production technical field.
Background technology
Michelia chapensis (Michelia chapensis Dandy) is Magnoliaceae Michelia aiphyllium, originate in Guangdong, like warm and humid weather, optimum growth temperature is 15 ~ 32 DEG C, it was reported that its ability 41 DEG C of high temperature, actual its performance of Wuhan Area show its more than 40 DEG C under hot environment growth perfonnance not good, occur that tree vigo(u)r fails, branch is wilted, the symptoms such as leaf portion is shrivelled.Chrysanthemum yulan, to pernicious gas better resistances such as pernicious gas sulphur dioxide, chlorine, therefore has good using value.
Summary of the invention
At present, Michelia chapensis is applied very wide in Central China, nursery, south China and engineering.For effectively solving this tree kind in the not good difficult problem of Landscape Expression in summer, cost-saving, the invention provides a kind of take Michelia chapensis as the high method connecing chrysanthemum yulan of stock, the method with chrysanthemum yulan for fringe bar carries out high-grafting.
Taking Michelia chapensis as the high method connecing chrysanthemum yulan of stock, take Michelia chapensis as stock, with chrysanthemum yulan for scion, carries out grafting in spring or autumn.The method time year increment was higher than 1 year raw seedling, and can reach 80 ~ 150cm, girth growth can reach 0.5 ~ 1cm.
Preferably, with the Michelia chapensis of life in 2 ~ 3 years for stock.
Diameter of stock is larger on the impact of land for growing field crops graft survival rate, with the increase of diameter of stock, graft survival rate declines, can be used as stock as seedling more than plant height 50cm, footpath base more than diameter 0.8cm and carry out grafting, when selecting stock, the Michelia chapensis preferably selecting 2-3 raw is stock, and the amount of growth of such grafting can reach optimal effectiveness.
Preferably, with the substantial growth branch of annual chrysanthemum yulan for scion, branch internode is even, eye is full, and rugosity is at 0.6 ~ 0.8cm.
Scion should choose annual substantial growth branch, requires that branch internode is even, eye is full, and rugosity is at about 0.7cm, and green tender and moisture foot, this branch does scion, and survival rate generally all reaches more than 90%.Test finds that scion degree of lignification and graft survival rate are inversely proportional to, and degree of lignification is high, and graft survival rate is low, otherwise then high, and because degree of lignification is low, cellular tissure is tenderer, energetic, easily heals, and therefore survival rate is high.
Grafting time all can carry out in spring or autumn.Spring generally adopts branch cut-grafting, autumn generally adopts simple bud side grafting, result of the test shows, these two kinds of grafting methods have more outstanding survival rate, also different advantages has been shown respectively, the survival rate of branch cut-grafting in spring can reach 90%, and the survival rate of simple bud side grafting in autumn then can ensure more than 95%.Adopt different seasons different grafting methods can obtain higher survival rate, suitable grafting time and method can be selected according to the weather conditions of locality.
Preferably, the spring grafting time is Gregorian calendar mid or late Febuary.
3 ~ April, graft survival rate was extremely low, as long as but the plant strain growth survived is fabulous, and within 1 year, nearly 0.8 meter can be grown, dry thick 1cm, and form multiple branch, form little tree crown.
Preferably, comprise the steps:
1) overhead cut off at 5 ~ 7cm place at stock, put down and cut section, vertically cut in the cortex on otch and be deep to 2.5 ~ 3.5cm;
2) cut by branch disconnected at the reverse side of the bud section of scion branch, 2 ~ 3cm place, bottom of bud bud, otch becomes 30 degree of inclined-planes, then the branch that reverses, and aims at former tangent plane, and prune 2 ~ 3cm, then scion is cut off by 1 ~ 2cm place above bud;
3) insert in stock by scion, the formation layer of scion and stock is at least one in the face of neat, then wraps up with the film strip of wide 2 ~ 3cm.
Preferably, autumn, grafting time was 9 ~ October of the Gregorian calendar.
9 ~ October is the Best Times of grafting in autumn, and the grafting of bag bud sent forth branches in March next year-April, and grafting time can not exceed late October at the latest, and stop if exceeding seedling growth phase late October, interface can not heal completely.
Grafting branch used preferably accomplishes that along with the prolongation of branch resting period, graft survival rate reduces gradually with adopting with connecing.If can not carry out with connecing at once, in order to prevent moisture loss, the branch under adopting being processed in time, first with moistening cotton balls, the clip of branch being wrapped sealing, then be stored in 4 DEG C of refrigerators and preserve, but the branch preserved so preferably completed grafting within one week.
Preferably, comprise the steps:
1) straight one side is selected along skin zone and the downward rip cutting of xylem intersection to cut cortex at the belly of stock overhead 7 ~ 10cm;
2) under the bud of scion, splay the bevel at angle at 45 ° in 1 ~ 2cm place, again by smooth for scion one side upset upwards, cortex of pruning from bud point to the tip of bevel, finally turns scion side, bud point upwards, cut disconnected by the inclined-plane that 0.5 ~ 1cm sentences 60 ° above bud point by scion;
3) insert in stock by scion, the formation layer of scion and stock is at least one in the face of neat, then wraps up with the film strip of wide 2 ~ 3cm.
With Magnoliaceae aiphyllium Michelia chapensis for stock grafting deciduous tree chrysanthemum yulan, transplanting survival rate is high, and tree vigo(u)r recovers fast.Grafting nursery stock then shoot length generally can reach 30 ~ 40cm, and the 2nd year winter, height of seedling reached 80 ~ 120cm.
