The invention provides a kind of Chinese toon bud grafting propagation method, choose robust growth, leading thread 1.0-1.2cm Chinese toon then raw tree seedling as stock, from Chinese toon elite stand take stalwartness, sprout full carry out bud grafting without damage by disease and insect current-year branch, thus realize Chinese toon and expand numerous.Bud grafting is specially: healthy and strong sprout in the middle part of branch is chosen in scion, and apart from the horizontal partial application in bud 0.5cm place above bud, cut 0.5cm place horizontal partial application again to bud downwards, bud sheet need be with a part of xylem, thickness 2-3mm, and bud sheet bevel length is between 1.0-1.5cm; Choose the face, northeast of stock, to prune a slice skin bit apart from 5cm place, ground, stock cuts that method is identical with scion, and then taking off peeled block, be attached on cut face rapidly by bud sheet, aligns with tangent plane lower cut in bud sheet lower end, then use bar rope tighten.The present invention has simple to operate, the feature of graft survival rate high (more than 86%), and the nursery stock cultivated is high, Diameter growth is all very rapid, for Chinese toon breeding preservation from now on and utilization are had laid a good foundation.
Description
Technical field
The present invention relates to plant seedling-wood breeding field, specifically, relate to a kind of Chinese toon bud grafting propagation method.
Background technology
Chinese toon be China excellent with material, edible and Landscape Trees, rapidly, resistant to diseases and insects is strong, strong adaptability, and material is good, beautiful texture in its growth, and tool aromatic odor, and have the title of " mahogany of China ", is first-class furniture material; 2012, Chinese toon was put into Eleventh Five-Year Plan project, to carry out more extensively more deep research to Chinese toon, effectively developed Chinese toon good resource, promoted the development of China's fast-growing timber forests cause faster and better.
But for a long time, the development of Chinese toon and research rest on more cultivates and on breed breeding, to the preservation of the excellent genetic character of the improved seeds selected with develop rare research, this improved seeds Breeds resources of Chinese toon is made to can not get better developing faster.
The preservation of Chinese toon breeding and utilization, must be realized by vegetative propagation, and therefore, the success of Chinese toon Grafting Experiment, for the development and utilization of Chinese toon breeding is had laid a good foundation.
Summary of the invention
The object of this invention is to provide a kind of Chinese toon bud grafting propagation method.
In order to realize the object of the invention, a kind of Chinese toon bud grafting propagation method of the present invention, choose robust growth, leading thread 1.0-1.2cm Chinese toon then raw tree seedling as stock, from Chinese toon elite stand take stalwartness, sprout full carry out bud grafting without damage by disease and insect current-year branch, thus it is numerous to realize Chinese toon expansion.
The concrete operations of bud grafting are: healthy and strong sprout in the middle part of branch is chosen in scion, apart from the horizontal partial application in bud 0.5cm place above bud, cut 0.5cm place horizontal partial application again to bud downwards, bud sheet need be with a part of xylem, thickness 2-3mm, bud sheet bevel length is between 1.0-1.5cm; Choose the face, northeast of stock, to prune a slice skin bit apart from 5cm place, ground, stock cuts that method is identical with scion, and then taking off peeled block, be attached on cut face rapidly by bud sheet, aligns with tangent plane lower cut in bud sheet lower end, then use bar rope tighten.
10-15 days stumps after grafting, namely apart from 1cm place, interface upper end, cut off stock top; Connect rear timely bud picking 3-4 time, until grafting bud is grown up healthy and sound, normal management, after scion growth firmly, carried out solution and tied up vegetative period.
Concrete steps are as follows:
(1) stock cultivate: during Chinese toon seed maturity in October, choose healthy and strong Chinese toon maternal plant, gather full, without damage by disease and insect fruit, dry after adopting, take out seed, seed taking-up after dry wing, load in ventilative woven bag, hang over ventilation rainproof place.March next year is sowed, with the water seed soaking 4 hours of about 35 DEG C before sowing, remove floating superincumbent flat kind, mix sand to broadcast sowing, seedbed is high bed furrow, wide 60-70cm, high 20cm, at the two back gauge bedside 10cm places in seedbed, respectively open a ditch drilling, ditch depth about 5cm, first water in ditch after trench digging, and then sow, seed will evenly be sowed, hack is covered after spreading, sow after 5-7 days, water according to sowing ground soil moisture content in good time, sprinkling method is to pour water along the low pavement between seedbed, directly can't water on seedbed, be unearthed in case soil compaction affects seed germination.Then, water and weeding by ground, garden normal management.When young plant grows to 7-9 sheet leaf, carry out thinning, spacing in the rows is 15-20cm, afterwards normal management.
(2) scion collection: before spring, Chinese toon bud sprouted, chooses robust growth, without the raw then healthy and strong branch on damage by disease and insect maternal plant, adopt lower after wrap up with newspaper immediately, in order to avoid dehydration, after all having adopted, carried out sand and hide, sand humidity is advisable to hold into the not loose not water outlet of bulk.When gathering scion, ensureing, under the leaf bud prerequisite of not sprouting, to adopt evening as far as possible, because if the morning that scion is adopted, the temperature less than grafting can not grafting, and scion storage time is long easily to be affected scion quality and cause graft survival rate to reduce.
(3) grafting method: the method adopting bud grafting, scion, with connecing with getting, can not all be taken out in order to avoid dehydration.Grafting bud sheet chooses healthy and strong sprout in the middle part of branch, apart from the horizontal partial application in bud 0.5cm place above bud, cuts 0.5cm place horizontal partial application again to bud downwards, bud sheet need be with a part of xylem, thickness about 2mm, the wide 0.5-0.7cm of bud sheet bevel, length is between 1.0-1.5cm.Choose the face, northeast of stock, at a slice skin bit of pruning apart from 5cm place, ground, it is substantially identical with scion that stock cuts method, skin bit of pruning is as far as possible identical with bud sheet size, then peeled block is taken off, be attached on cut face by bud sheet rapidly immediately, aliging with tangent plane lower cut in bud sheet lower end, has twined tighten afterwards with plastic strip.
(4) connecing rear management: 10-15 days stumps after grafting, namely locating apart from interface upper end about 1cm, cutting off stock top; Connect rear timely bud picking 3-4 time, until grafting bud is grown up healthy and sound.Vegetative period normal management, June, after scion growth firmly, scratches plastic strip with blade and carries out solution and tie up.
The present invention has the following advantages:
(1) seed treatment: Chinese toon capsule goes wing to get kind after plucking, and place aeration-drying place storage, in case the mold of seed, affect germination rate in the coming year; Broadcast the vernalization in 4 hours of front emerge in worm water, shorten sprouting time, be conducive to kind of bud and be unearthed, improve planting percent.
(2) scion is selected: choose robust growth, without the raw then stalwartness on damage by disease and insect maternal plant, sprout full without damage by disease and insect branch, branch is healthy and strong, and sprout is full, and nutrient is sufficient, to ensure sprout impact supply after grafting, improve graft survival rate and healthy growth.
(3) grafting method: the present invention adopts bud grafting, easy and simple to handle, save scion, survival rate is high.
(4) the present invention has simple to operate, the feature that graft survival rate is high, use grafting method survival rate of the present invention more than 86%, the nursery stock cultivated is high, Diameter growth is all very rapid, have laid a good foundation for Chinese toon breeding is from now on preserved and utilized.
