Problems solved by technology

[0003] (1) The rooting rate of stone fruit trees such as peaches, apricots, plums, cherries, etc. is low, and some varieties are even difficult to root
[0004] (2) The existing cutting technology is mainly to cut the branches into sections and cut them into the substrate. Different parts of the cuttings have different degrees of difficulty in rooting, resulting in a large difference in the rooting time of the cuttings, which makes management more difficult
[0005] (3) The existing cutting technology has weak cutting meristem ability, low auxin content, and relatively slow rooting. The high temperature and high humidity of the environment will easily lead to the acceleration of the reproduction of various pathogenic bacteria in the substrate, causing the lower part of the cuttings to rot, which affects the survival rate of cuttings

Embodiment 1

[0033] Embodiment 1 drupe fruit tree and rootstock tender slightly cuttage method

[0034] Taking the peach tree variety 'Meiyue' as an example, the experiment was carried out in the experimental base of Weifang Academy of Agricultural Sciences according to this implementation plan. The experiment set up a treatment group and a control group:

[0035] Treatment group: adopt cutting method of the present invention:

[0036] Include the following steps:

[0037] (1) Cultivate cuttings with strong meristematic ability

[0038] Select tissue-cultured seedlings to establish ear-picking gardens, top off when the branches of the seedlings grow to 30 cm, and top off the top 5 cm of new shoots twice, and spray a mixed solution of 60 ppm cytokinin and 80 ppm of naphthaleneacetic acid within 1 to 3 days after topping. Spray 2 times in a row to keep the tender tissue in an active meristematic state.

[0039] Pick the heart twice, and the new shoots that grow out the second time will gr...

Abstract

The invention discloses a stone fruit tree and stock tender tip cutting method. The method comprises the steps of cultivating of cutting shoots with the high reproduction capacity, cutting shoot treating and tender tip cutting. According to the cutting method, young trees and tender tips keep an active plant tissue state; pinching is continuously conducted, and cytokinin and naphthylacetic acid are sprayed after pinching and sprayed again before shoot cutting, so that tissue cells keep the young active state; the cytokinin content of the trees is increased, and therefore calluses are easy to form; the rooting substance content is increased, therefore, rooting is easy, the rooting time is 5-7 days ahead, the rooting rate reaches 97% or above, the seedling rate is obviously increased, and the economic benefit is increased by 80% or above. The method is low in management difficulty, labor is saved, and the advantages of being easy to operate and popularize and the like are achieved.

Description

technical field [0001] The invention relates to a cutting seedling raising method, in particular to a cutting method for drupe fruit trees and rootstocks, and belongs to the technical field of plant propagation. Background technique [0002] Cutting is a traditional plant vegetative propagation technology. Fruit tree cutting propagation has been applied as early as 2000 years ago. After years of development in China, cutting technology is becoming more and more mature. , and its development is changing with each passing day. There are many types of drupe fruit trees, including peaches, plums, apricots, cherries, etc. The main propagation methods are grafting and cuttings. Cuttings are also used for rootstock propagation. At present, research on cuttings of stone fruit trees and rootstocks in my country is still in progress. The existing cutting methods mainly use semi-lignified cuttings, but there are the following deficiencies: [0003] (1) Drupe fruit trees such as peac...
