Abstract

The invention discloses a kind of root system propagation method of white birch, white birch root soil is excavated, its root system main root or thick root are taken in cave as stock, the thick root of other white birches of no disease and pests harm is chosen as newly connecing root, it is slightly less than white birch rootstock, breeding operation that it, which newly connects root upper end bond diameter,：In place of above-mentioned white birch 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 of white birch rootstock interface hole, and insert grafting within the conical hole of corresponding white birch rootstock, make the root bar of new grafting in cave in order, be put into organic fertilizer, fill out soil, water drenching, makes the white birch root system of new grafting supply white birch water and nutrient.

Description

A kind of root system propagation method of white birch

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

The establiss of white birch plant seedlings, occurs when generally because of transplanting in cut-off parts root system, or white birch growth course 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 white birch there is provided one kind Good root system, is allowed to survival rate height, effect is big, cost is low, easy to operate, efficiently white birch 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 white birch is excavated White birch 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 white birch as newly root is connect, it newly connects root Upper end bond diameter is slightly less than white birch rootstock diameter.

Breeding operation：White birch root soil is excavated, in place of above-mentioned white birch 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 white birch rootstock interface The conical piece-root grafting head of hole, and inserting within the conical hole of corresponding white birch rootstock, 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 white birch root system of new grafting is supplied white birch water and nutrient.

The structure and advantage of the present invention are made further to illustrate with reference to embodiment, raw white birch seedlings transplanting in 2 years, Annual spring grows to root of the underground silver birch 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 white birch tree root bar of no insect pest of other 4 years raw white birches 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 white birch nursery stock.

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

Claims

1. a kind of root system propagation method of white birch, excavates white birch 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 white birches as newly connecing root, It is slightly less than white birch rootstock diameter, breeding operation that it, which newly connects root upper end bond diameter,：White birch root soil is excavated, the handle in cave In place of above-mentioned white birch root system stock interface, with special conical drill bit, conical hole is got out, above-mentioned other white birches are newly connect root Upper end connector, is planed out with pencil-knife and is fit to the conical piece-root grafting head of white birch rootstock interface hole, and inserts corresponding white Birch 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 white birch root system of new grafting is set to supply white birch water and nutrient.
