Problems solved by technology

It takes a long time for egg yolk fruit seedlings to enter the fruiting period, and the variation is serious, and the excellent traits of the female parent cannot be maintained; the seeds for rootstock cultivation of grafted seedlings are limited, and the cultivation period of grafted seedlings needs 2-3 years; The operation is cumbersome, and the branch materials used for barge are limited, which will affect the canopy of the mother tree after barge, and the large-scale and industrialized seedling breeding cannot be realized in a short period of time.
There is no report on the successful propagation of lucuma cuttings

Embodiment 1

[0042] Carry out with reference to aforementioned operation method, wherein the specific requirements and parameters of cuttings selection and cuttings processing are as follows:

[0043] Selection of cuttings: During the post-harvest pruning period of egg yolk orchard on February 18, 2017, the branches of the mother tree of the excellent variety "Xiantao No. 1" of lucuma were selected, and semi-lignified terminal buds with strong growth in the sun, full bud eyes, and no pests and diseases were selected. branches.

[0044] Cutting treatment: Soak in the prepared rooting solution for 2 hours, the rooting solution is 200ppm solution of 3-indolebutyric acid.

[0045] On June 18, 2017, the growth of cutting seedlings was investigated. 50 plants were randomly investigated, and the survival rate was 68.6%. plants, the survival rate and rooting rate are low.

Embodiment 2

[0047] Carry out with reference to aforementioned operation method, wherein the specific requirements and parameters of cuttings selection and cuttings processing are as follows:

[0048] Selection of cuttings: During the post-harvest pruning period of the egg yolk orchard on February 18, 2017, the branches of the mother tree of the excellent variety "Xiantao No. 2" of the egg yolk fruit were selected, and the annual mature branches with strong growth in the sun, full bud eyes, and no pests and diseases were selected.

[0049] Cutting treatment: Soak in the prepared rooting solution for 5 hours, the rooting solution is a solution of 200ppm 3-indolebutyric acid+200ppm 3-indoleacetic acid.

[0050] On June 18, 2017, the growth of cutting seedlings was investigated. 50 plants were randomly investigated, and the survival rate was 83.5%. strains, with higher survival rate and root output.

Embodiment 3

[0052] Carry out with reference to aforementioned operation method, wherein the specific requirements and parameters of cuttings selection and cuttings processing are as follows:

[0053] Selection of cuttings: During the post-harvest pruning period of the egg yolk orchard on February 18, 2017, the branches of the mother tree of the excellent variety "Xiantao No. 2" of the egg yolk fruit were selected, and the semi-lignified terminal buds with strong growth in the sun, full bud eyes, and no pests and diseases were selected. branches.

[0054] Cutting treatment: soak in the prepared rooting solution for 5 hours, the rooting solution is 200ppm solution of 3-indolebutyric acid.

[0055] On June 18, 2017, the growth of cutting seedlings was investigated, 50 plants were randomly investigated, and the survival rate was 61.5%. plant, the survival rate is low, and the root output is average.

Abstract

The invention discloses a cuttage breeding method of lucuma nervosa, and relates to the technical field of lucuma nervosa seedling breeding. The cuttage breeding method comprises the steps that a non-woven fabric nutrition bag is selected as a cuttage container, a cuttage medium in the nutrition bag is contained in two layers, a nutrient medium special for seedling raising is arranged at the bottom layer, and a medium formed by mixing yellow core mud and perlite is arranged on the upper layer; cutting slips are selected in a retraction pruning period after lucuma nervosa is picked in winter, and a good variety of lucuma nervosa 'flat peach No.1' or 'flat peach No.2' is selected as a seed tree for picking the slips; and before cuttage, 3-indolebutyric acid or a rooting solution prepared from 3-indolebutyric acid and 3-indoleacetic acid is used for soaking treatment. The cuttage breeding method of the lucuma nervosa has the advantages of being simple in process, easy to operate, high in survival rate, high in breeding speed, short in seedling raising period, low in cost, good in market prospect and the like, is suitable for large-scale application and popularization, and rapidly achieves large-scale industrialization of lucuma nervosa seedling breeding.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of 2018.10.30, an application number of 201811281292.5, and an invention title of "Method for Cutting Propagation of Lucuma". technical field [0002] The invention belongs to the technical field of lucuma seedling breeding, and in particular relates to a cutting breeding method of lucuma. Background technique [0003] Lucuma nervosa (Lucuma nervosa A.DC), also known as lion head fruit, egg fruit, peach olive, fairy peach, etc., is a perennial tropical rare fruit tree of the family Lucuma genus. Originally produced in Cuba and tropical South America, it was introduced into my country in the 1930s. Now there are sporadic distributions in Hainan, Guangdong, Guangxi, Yunnan and other hot areas. The ripe fruit of lucuma is orange-yellow, and the pulp resembles egg yolk. It is powdery and sweet, and has a unique taste. The fruit is rich in plant polysaccharides, starch, c...
