Abstract

The invention discloses a kind of root system propagation method of ginkgo, ginkgo root soil is excavated, its root system main root or thick root are taken in cave as stock, the thick root of other ginkgoes of no disease and pests harm is chosen as newly connecing root, it is slightly less than ginkgo rootstock, breeding operation that it, which newly connects root upper end bond diameter,：In place of above-mentioned ginkgo root system stock interface in cave, with special conical drill bit, conical hole is got out, newly end connector on root is connect above-mentioned, is planed out with pencil-knife and be fit to the conical piece-root grafting head in ginkgo rootstock interface holes hole, and insert grafting within corresponding ginkgo rootstock round taper hole hole, make the root bar of new grafting in cave in order, be put into organic fertilizer, fill out soil, water drenching, makes the ginkgo root system of new grafting supply ginkgo water and nutrient.

Description

A kind of root system propagation method of ginkgo

The present invention relates to forestry plant technical field of cultivation, the root system propagation method of particularly a kind of ginkgo.

The establiss of Gingko biloba plant seedlings, cut-off parts root system when generally because of transplanting, or occur during Ginkgo Growing Rotten of old complaint, influence survival rate and be directed at growth it is slower.

The purpose of the present invention is that reply prior art weak point is excellent using adhoc approach propagation by grafiting ginkgo there is provided one kind Good root system, is allowed to survival rate height, effect is big, cost is low, easy to operate, efficiently ginkgo root system propagation method.

To achieve the above object, the present invention is implemented using following technical scheme, and a kind of root system propagation method of ginkgo is excavated Ginkgo root soil, takes its root system main root or thick root as stock, with to be grafted in cave.

Choose develop substantial, best in quality, bright and clean root bar, no disease and pests harm, the thick root of ginkgo as newly root is connect, it newly connects root Upper end bond diameter is slightly less than Root of Ginkgoes diameter of stock.

Breeding operation：Ginkgo root soil is excavated, in place of above-mentioned ginkgo root system stock interface in cave, special circular cone is used Shape drill bit, gets out conical hole, newly connects end connector on root above-mentioned, is planed out with pencil-knife and be fit to ginkgo rootstock interface The conical piece-root grafting head of hole, and inserting within corresponding ginkgo rootstock round taper hole hole, after inserted with CARBURIZING FURNACE FOR STAINLESS FASTENER nail rotation Fastened in the grafting seam for entering both, rear colligation plastic strip consolidates it, makes the root bar of new grafting in cave in order, be put into organic fertilizer, Soil is filled out, water drenching drenches a water in later 3 to 6 days, the ginkgo root system of new grafting is supplied ginkgo water and nutrient.

The structure and advantage of the present invention are made further to illustrate with reference to embodiment, raw ginkgo seedlings transplanting in 2 years, Annual spring grows to root of the underground ginkgo rhizome for diameter more than 1 centimetre as stock, excavates and is found out in surface soil, cave Stock grafting mouthful is done in thick root root footpath more than 1 centimetre, is that 1 centimetre of conical drill bit gets out conical grafting hole with Special diameter, It is waiting, nutritious, best in quality, the ginkgo tree root bar of no insect pest of other 4 years raw ginkgoes is selected, interception root head end is a diameter of 1 centimetre, simultaneously size, corresponding to the conical grafting head of tree root stock hole, inserts stock for its root graft end of being planed with pencil-knife Interior grafting it, then with a diameter of 0.1 centimetre, length meets screw-in to fasten along connecing for 1 centimetre of CARBURIZING FURNACE FOR STAINLESS FASTENER nail, then with a width of Make the tree root bar of new grafting in 2 centimetres of plastic strip colligation moisturizing, cave in order, be put into chicken manure and chaff mixture base manure, then fill Soil, water drenching can guarantee that humidity to reach that the new root system of breeding is to want needed for supplying Seedlings of Ginkgo biloba.

It is an advantage of the invention that：It is easy to operate, quick, reproductive survival rate height is improved with ginkgo improved seeds, grafting is new Root growth is fast, and ginkgo more easily absorbs water and nutrient.

Claims

1. a kind of root system propagation method of ginkgo, excavates ginkgo root soil, its root system main root or thick root are taken in cave as anvil Wood, with to be grafted, choose develop substantial, best in quality, bright and clean root bar, no disease and pests harm, the thick root of other ginkgoes as newly connecing root, It is slightly less than Root of Ginkgoes diameter of stock, breeding operation that it, which newly connects root upper end bond diameter,：Ginkgo root soil is excavated, the handle in cave In place of above-mentioned ginkgo root system stock interface, with special conical drill bit, conical hole is got out, above-mentioned other ginkgoes are newly connect root Upper end connector, is planed out with pencil-knife and is fit to the conical piece-root grafting head in ginkgo rootstock interface holes hole, and inserts corresponding silver Apricot rootstock cone hole within, after with CARBURIZING FURNACE FOR STAINLESS FASTENER follow closely rotation insertion both grafting seam in fasten, rear colligation plastics Bar consolidates it, makes the root bar of new grafting in cave in order, is put into organic fertilizer, fills out soil, and water drenching drenches a water in later 3 to 6 days, The ginkgo root system of new grafting is set to supply ginkgo water and nutrient.
