Abstract

A grafting method of castanea mollissima comprises the steps that castanea mollissima which is lower than 20 cm from the ground is selected as a rootstock to be grafted, and a castanea mollissima branch which has one or two full axillary buds, is sufficient in development, good in quality, smooth and clean in branch and free of diseases and insect pests and is lignified or semi-lignified serves as a scion; grafting is conducted, wherein a conical hole is drilled in the union position of the castanea mollissima rootstock through a special conical drill bit, a conical scion joint matched with the hole of the rootstock union is planed through a pencil on the scion joint and inserted into the conical hole of the rootstock, a stainless steel screw is inserted into the grafting seam of the rootstock and the scion in a screwed mode, and then a plastic strip is used for bundling. The grafting method has the advantages that operation is easy and convenient, matching and connecting of graft unions are firm, and the survival rate is high.

Description

The grafting method of a kind of Chinese chestnut

The present invention relates to forestry plant technical field of cultivation, particularly the grafting method of a kind of Chinese chestnut.

The plant cultivation maintenance of deciduous tree, usually to sow, to intercut, the breeding of the method such as grafting, to improve, quality product, survival rate are high in its artificial propagation, one of the easy important directions for people's pursuit of production operation, the grafting method of tradition Chinese chestnut, the area that stock and scion are bonded with each other or less, easily loosen, affect survival rate and be directed at growth comparatively slow, and grafting operation is slower.

The object of the invention is to tackle existing graft technology weak point, a kind of quality product adopting adhoc approach grafting Chinese chestnut is provided, make it that survival rate is high, effect is large, cost is low, grafting method that is easy and simple to handle, Chinese chestnut efficiently.

For achieving the above object, the present invention uses following technical scheme to implement, the grafting method of a kind of Chinese chestnut, and the Chinese chestnut choosing less than liftoff 20 centimetres high is stock, and stock interface diameter is 1 centimetre, with to be grafted.

Choose with 1 to 2 full axillalry bud, grow substantial, best in quality, branch is bright and clean, without the Chinese chestnut branch of damage by disease and insect, lignification semi-lignified as scion, its fringe segment length is no more than 10 centimetres, and its lower end connector branch diameter is 1 centimetre.

Grafting operation: above-mentioned Chinese chestnut stock interface part, with the special conical drill bit of diameter 1 centimetre, get out conical hole, above-mentioned scion joint, plane out with pencil-knife and be fit to the conical scion joint of stock interface hole, and insert within the conical hole of corresponding stock, rear CARBURIZING FURNACE FOR STAINLESS FASTENER nail revolves in the grafting seam inserted both it, colligation plastic strip firm it.

Below in conjunction with embodiment, structure of the present invention and advantage are further illustrated, Chinese chestnut seed is bred in control, growing to liftoff 20 centimeters tree stems in annual spring is that the seed of diameter 1 centimetre is as stock, sawed-off above stem wood branch discards, equating stock mouth, conical grafting hole is got out downwards with special conical drill bit, select nutritious, best in quality, the full chestnut tree branch without insect pest in bud position, getting length is 9 centimetres, plane out corresponding to the conical grafting head of stock grafting hole at bottom pencil-knife, and to insert in stock grafting it, then it is 0.1 centimetre with diameter, length is that the CARBURIZING FURNACE FOR STAINLESS FASTENER nail of 1 centimetre screws in fastening along seam, again with wide be the plastic strip colligation moisturizing of 2 centimetres, moisturizing humidity with reach meet grafting scion growth institute be required to be want.

Advantage of the present invention is: easy and simple to handle, quick, and after having tool Chinese chestnut improved seeds to improve grafting, survival rate is high, and scion growth is fast, and Chinese chestnut grafting tone closes firmly advantage.

Claims

1. the grafting method of a Chinese chestnut, it is characterized in that: the Chinese chestnut choosing less than liftoff 20 centimetres high is stock, stock interface diameter is 1 centimetre, with to be grafted, choose with 1 to 2 full axillalry bud, grow and enrich, best in quality, branch is bright and clean, without damage by disease and insect, the Chinese chestnut branch of lignification semi-lignified is as scion, its scion segment length is no more than 10 centimetres, its lower end connector branch diameter is 1 centimetre, grafting operation: above-mentioned Chinese chestnut stock interface part, with the special conical drill bit of diameter 1 centimetre, get out conical hole, above-mentioned scion joint, plane out with pencil-knife and be fit to the conical scion joint of stock interface hole, and insert within the conical hole of corresponding stock, revolve with CARBURIZING FURNACE FOR STAINLESS FASTENER nail again in the grafting seam inserted both it, then use colligation plastic strip firm it.
