Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0021] The embodiment of the present invention provides a kind of method of hazelnut cutting propagation, comprises the following steps:

[0022] S1. Horizontal constriction treatment: In Xunyi County, northern Xianyang, Shaanxi, in early and mid-August, galvanized iron wire with a thickness of No. 22 was used to constrict the internodes of the big hazelnut seedlings at about 2 cm below the buds at intervals; from the surface Start at 8cm upwards, and hang horizontally at intervals of 10cm. It is ...

Abstract

The invention discloses a cutting propagation method for hazelnuts. The method comprises the following steps of, using galvanized iron wires to carry out spaced multi-channel tight bundling on internodes 2cm below buds of current-year large hazelnut sprouting seedlings in the first ten days and the middle ten days of August; after leaves fall in winter in the current year, cutting off the sprouting seedlings subjected to the constriction treatment with heels at the positions 2cm in soil from the base parts; and cutting the whole sprouting seedlings subjected to the constriction treatment into branch sections from the constriction position close to the lower parts of the iron wires, removing the iron wires, binding every 20-30 branch sections into a bundle according to the requirement of consistent polarity, inserting the branch sections into a thidiazuron soluble solution with tips upwards, soaking for 24 hours, and inserting the branch sections into a cutting nursery paved with a black mulching film according to the row spacing of 20 cm and the plant spacing of 10 cm, wherein the insertion depth is 2/3 of the length of the cutting slips. According to the method, the problem that rooting is not prone to occurring in hard wood cutting is solved, operation is easy and convenient, the propagation coefficient is high, sprouting seedlings at the root of a hazelnut tree can be more fully utilized, meanwhile, the effect of controlling excessive growth of sprouting tillers can be achieved to a certain degree, and the influence on the growth result of the hazelnut tree is reduced.

Description

technical field [0001] The invention relates to the technical field of hazelnut seedling cultivation, in particular to a method for cutting and propagating hazelnuts. Background technique [0002] Hazelnuts are an ancient species of nut tree. The Pingou hybrid hazelnut, also known as Pingou big hazelnut or big hazelnut, is bred by crossing the Pingou hazelnut native to my country and the imported hazelnut, which is currently widely planted in various parts of our country. For the propagation of hazelnuts, the methods of layering propagation, tiller propagation and green branch cutting propagation are mainly adopted in production, and hard branch cuttings are used, which generally have the problems of not being easy to take root and low survival rate. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for cutting propagation of hazelnuts, which overcomes the difficult problem that hard branch cuttings are not ea...
