Abstract
The invention relates to a Sichuan pepper seedling xylem bud grafting method. The Sichuan pepper seedling xylem bud grafting method includes the following steps that prepared high-quality Sichuan pepper scion plump buds are cut into the shape of horse ears and taken down for use; a horse ear shape is formed by cutting a 10 cm to 20 cm high smooth portion of the trunk of each seedling, the plump buds with xylem of scions prepared in advance are inlaid in stocks, the xylem portions and the stocks are tightly combined, the lower ends of the xylem portions are tightly inlaid in the stocks, then the xylem buds are fixed through plastic bags, the portions to be bound and grafted of the plump buds are exposed, the wounds are tightly wrapped to prevent water loss, and thus wound healing and formation of callus tissue are facilitated; after the stocks and the buds with xylem of the scions are fixed, the trunks are cut. The Sichuan pepper seedling xylem bud grafting method is suitable for grafting of Sichuan pepper seedlings and young Sichuan pepper trees which grow for more than one year and are low in quality and yield and low-yield improvement to old trees and has the main advantages that the contact area of the cambium is large, healing is easy, the trees grow fast after grafting and can bear fruit early.
Description
Technical field
The present invention is agricultural planting field, is specially the wooden bud grafting method of a kind of Chinese prickly ash nursery stock.
Background technology
Chinese prickly ash is long at China's cultivation history, how extensively to plant at Around the house, garden four sides, hillside ridge, yields poorly down, and benefit is not high.For further promoting Chinese prickly ash quality and yield, improve household economy income, in recent years, how various places all retain fine quality in exploration, extend Chinese prickly ash trees growth year, increase the problems such as damage by disease and insect resistance.Researcher has spent a large amount of manpower and materials in Chinese prickly ash grafting, grafting method is from cleft grafting, cut-grafting, " T " shaped budding, to last slotting skin, survival rate is from unstable (10-70%) that starts to the last motility rate (more than 85%) that is stable into.
Chinese prickly ash seedling grafting is subject to the impact of grafting time and grafting method, due to factors such as grafting difficulty are large, and survival rate is low, technical requirement height, is a most active field in current Chinese prickly ash research, is also a main Technique Popularizing project in Chinese prickly ash cultivation from now on.The Chinese prickly ash nursery stock of employing with wooden bud grafting method grafting, plant percent than other grafting graftings is high, tree vigo(u)r is strong, result 1-2 ahead of time, and best in quality, resistance and output are high, have both solved seedling offspring and have separated large problem, have ensured again the stable delivery of high-quality Chinese prickly ash kind good characteristic.
Summary of the invention
Mixed and disorderly for current Chinese prickly ash nursery stock kind, quality is low, the problems such as output is not high, the wild Chinese prickly ash of selecting local good stress resistance is stock, taking high grade producing Feng County clovershrub kind as scion, adopt new wooden bud grafting technology to improve graft survival rate, graft survival rate is reached more than 96%, realize early economic benefit.The present invention includes following steps:
The full bud of ready high-quality Chinese prickly ash scion is whittled into horse ear shape, takes off stand-by.
Cut equally a horse ear shape at smooth position, nursery stock mobile jib 10-20cm place, wooden being with of preprepared scion full bud is embedded on stock, wooden part and stock are combined closely, lower end and stock insert, fix wooden bud with plastic sack again, expose full bud and carry out colligation grafting part, wound Bao Yan, prevent water loss, so that the formation of wound healing and callus; After stock and the wooden bud of scion band are fixing, and mobile jib is cut to bar.
Effect of the present invention is: the wooden bud grafting method of Chinese prickly ash nursery stock of the present invention, it is to adopt wooden the taking off of the full bud band of high-quality scion that wooden bud grafting method, method are with in main employing, is embedded on stock, then reveals bud with plastic sheeting for farm use and wrap up wooden part, cutting back stock.Up to the present, through repetition test, graft technology of the present invention full maturity, grafting time is suitable, and technical measures are proper, and survival rate can be stabilized in more than 96%.The wooden bud grafting method of a kind of Chinese prickly ash nursery stock of the present invention, more than being applicable to life in 1 year, the Chinese prickly ash nursery stock that quality is low, output is lower and the grafting of Chinese prickly ash treelet and the transformation of veteran low yield, its major advantage is that formation layer contact area is large, healing easily, connect that rear growth is fast, result early.
Embodiment
The present invention is described in further detail below.
Embodiment 1
(1) selection of scion: the anosis worm harm developmental branch that clip kind is distinct, tree vigo(u)r is healthy and strong, the prime of life green pepper of high yield high-quality is set; Scion should be before germination 20-30 days or gather after fall foliage in the first year, for the elite stand of adopting fringe, should select kind pure, and the age of tree is raw at 5-10, and peripheral growth of tree crown enriched, and rugosity is at the developmental branch of 0.8-1.2mm;
(2) processing of scion: the part of after adopting, scion top not being enriched cuts off, be put in the ground kiln of 0-5 DEG C or shady and cool place, the highlyest can not exceed 8 DEG C, bury with the wet sand of relative moisture 70% left and right, after scion being taken out before grafting, soak with clear water, scion is fully absorbed water, or scion was put at normal temperatures in 2-3 days before grafting, it is sprouted;
(3) stock is prepared: select healthy and strong nursery stock to carry out grafting, treelet grafting, Ying Ju ground, level land 0.1m, breed improvement, far from 0.2m place, ground, is set greatly in hillside fields, can be sawed-off at trunk, major branch or side shoot place, scabble saw kerf, then, at the level and smooth side grafting fringe place of stock, remove horse ear shape;
(4) grafting
1) grafting time: Chinese prickly ash grafting: carry out before rudiment, mid-March is to early April;
2) scion is prepared: select full bud bevel to be the long horse ear shape inclined-plane of 3-5cm, the lower edge of a knife of scion bevel, at the very start to recessed, be horse ear shape and splay downwards, ensures that bevel has full bud not damage above;
3) insert with wooden sprout: determine sprout rugosity according to the rugosity of grafting part, when grafting, select scion middle part to enrich full bud, after scion is cut, scion horse ear shape lower end skin being inserted to the xylem of stock, combines closely in scion and stock position, exposing full bud with the plastic sheeting for farm use of 4-5 centimetre twines and ties up the wooden sprout of fixed band and carry out colligation, and then with plastic sheeting for farm use by whole the cross section of stock Bao Yan, then by plastic ties, whole sprout is tied up firmly, prevent that rainwater from infiltrating;
