Round-rod-like branch-layering fixing instrument

Abstract

The invention discloses a round-rod-like branch-layering fixing instrument and belongs to the technical field of seed stock breeding instruments. The round-rod-like branch-layering fixing instrument comprises a round rod body with wings, a rod cap and buckles. The lower end of the round rod body with wings is a tip, the part above the tip is the body which is a cylinder with a plurality of cambered wings. The upper small angle of each cambered wing is smaller than 90 degrees. When the fixing instrument stands in air, the the included angle between the axis of the cylinder of the rod body and the generatrix extension line of the convex surface center of each cambered wing is smaller than 90 degrees. The outer side of each cambered wing is provided with a breakage, the part above the breakage of each cambered wing is applied with external force and capable of being close to the lateral side of the cylinder of the rod body. The rod cap is mounted on the rod top above the body, the shape of the hollow part of a round bar of the rod cap is matched with that of the rod top. The buckles sleeve the round bar of the rod cap through a sleeve ring and are capable of rotating around the rod. By the round-rod-like branch-layering fixing instrument, branches of stock plants can be fixed to the earth surface and cannot be lifted by the branches of the stock plants. The round-rod-like branch-layering fixing instrument meets requirement on layering and seedling growth.

Description

technical field [0001] The invention relates to the technical field of tree seed breeding equipment, and belongs to a tree layering seedling raising device, in particular to a round bar type layering fixer. Background technique [0002] Layering propagation can use the branches of trees to produce new plants, the propagation speed is fast, and the new plants can fully maintain the excellent traits of the mother plant, which is of great significance to the breeding of improved trees. At present, the actual operation of layering propagation is mostly to press the branches of the mother plant with soil on the surface of the land to prevent the branches from bouncing and to fix the branches. But the branches of most trees have a certain degree of elasticity. If there is less soil pressed, the branches of the mother plant cannot be pressed; if there is too much soil, it will affect the germination of buds on the branches; Soil is also difficult. The whole layering operation p...

Problems solved by technology

But the branches of most trees have a certain degree of elasticity. If there is less soil pressed, the branches of the mother plant cannot be pressed; if there is too much soil, it will affect the germination of buds on the branches; Soil is also difficult

The entire beading operation process is laborious and time-consuming

At present, some people use tree branches to cut into stakes to fix the branches of the mother plant. The actual operation requires suitable branches as materials, and the branches need to be cut into stakes one by one. The whole operation process is also laborious and time-consuming, especially for fixing the mother plant with stakes The effect of the branches is poor: the stakes will be pulled up by the branches of the mother plant in rainy days; the stakes cut from fresh branches will be pulled up when the wood dries and shrinks; If the skin rots, the stake will also be pulled up; because the stake inserted into the soil is fixed by the friction between its vertical surface and the soil, the force of this friction is limited and affected by many factors will decrease

Due to the problem of fixing the branches of the mother plant, the current layering propagation of trees is limited to a small area, and it is impossible to reproduce and raise seedlings in large quantities
