Abstract

The invention discloses a method for grafting ulmus macrocarpa.The method includes using the selected ulmus macrocarpa with the ground heights lower than 20 centimeters as rootstock to be grafted; using selected sufficiently developed, high-quality, smooth and lignified or semi-lignified ulmus macrocarpa branches without plant diseases or insect pests as scions; carrying out grafting, to be more specific, drilling conical holes in ulmus macrocarpa rootstock ports by the aid of special conical drill bits, cutting by the aid of pencil sharpeners to obtain conical scion connectors, inserting the conical scion connectors into the corresponding conical holes of the rootstock, rotationally inserting stainless steel screws into grafted seams of the conical holes and the conical scion connectors and binding plastic strips.Each ulmus macrocarpa branch is provided with one to two full auxiliary buds.The conical scion connectors are matched with the holes of the rootstock ports.The method has the advantages of simplicity and convenience in operation, firm fit connection of grafted ports and high survival rate.

Description

A kind of engrafting method of big fruit elm

The present invention relates to forestry plant technical field of cultivation, particularly the engrafting method of a kind of big fruit elm.

The plant culture maintenance of deciduous tree, generally to sow, to intercut, the breeding of the method such as grafting, its artificial propagation to improve that quality product, survival rate be high, production operation is easy is one of the important directions of people's pursuit, the engrafting method of tradition big fruit elm, area that stock and scion are bonded with each other or less, easily loosen, affect survival rate and be directed at growth relatively slowly, and grafting operation is slower.

It is an object of the invention to tackle existing graft technology weak point, it is provided that a kind of quality product adopting the big fruit elm of adhoc approach grafting, so as to survival rate is high, effect is big, cost is low, engrafting method easy and simple to handle, big fruit elm efficiently.

For achieving the above object, the present invention uses following technical scheme to implement, the engrafting method of a kind of big fruit elm, and choosing liftoff big fruit elm 20 centimetres high following 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 pest and disease damage, lignifying semi-lignified big fruit Ramulus ulmi pumilae bar as scion, its fringe segment length is less than 10 centimetres, and its lower end connector branch diameter is 1 centimetre.

Grafting operation: above-mentioned big fruit elm stock interface part, with diameter 1 centimetre special cone drill bit, get out cone 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 corresponding stock cone hole, after with CARBURIZING FURNACE FOR STAINLESS FASTENER nail rotation insert both grafting seam in, colligation plastic strip consolidates it.

Further illustrate below in conjunction with the embodiment structure to the present invention and advantage, control to breed big fruit elm Seedling kind, 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, cone grafting hole is got out downwards with special cone drill bit, select nutritious, best in quality, the full big fruit elm branch without insect pest in bud position, taking length is 9 centimetres, plane out the conical grafting head corresponding to stock grafting hole at bottom pencil-knife, and insert in stock grafting it, then it it is 0.1 centimetre with diameter, the CARBURIZING FURNACE FOR STAINLESS FASTENER nail that length is 1 centimetre screws in fastening along seam, again with wide be the plastic strip colligation moisturizing of 2 centimetres, moisturizing humidity with reach to meet grafting scion growth is required to be will.

The invention have the advantage that easy and simple to handle, quick, after having tool big fruit elm improved seeds to improve grafting, survival rate is high, and scion growth is fast, and big fruit elm grafting tone closes firmly advantage.

Claims

1. the engrafting method of a big fruit elm, it is characterized in that: choosing liftoff big fruit elm 20 centimetres high following is stock, stock interface diameter is 1 centimetre, with to be grafted, choose with 1 to 2 full axil bud, grow and enrich, best in quality, branch is bright and clean, without pest and disease damage, the big fruit Ramulus ulmi pumilae bar of lignifying semi-lignified is as scion, its scion segment length is less than 10 centimetres, its lower end connector branch diameter is 1 centimetre, grafting operation: above-mentioned big fruit elm stock interface part, with diameter 1 centimetre special cone drill bit, get out cone 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 corresponding stock cone hole, insert in the grafting seam of both again with CARBURIZING FURNACE FOR STAINLESS FASTENER nail rotation, then it is consolidated with colligation plastic strip.
