Embodiment Construction

[0013] The rapid breeding method of the eucalyptus seedling of the embodiment of the present invention may further comprise the steps:

[0014] A. Selection and pretreatment of in vitro materials: Select the new branches of the year with good growth and no disease on the branches of Yushu, intercept the branches with 1-2 spores, make the lower incision at an angle of 45 degrees, and use 1000 times diluted water for the incision. Disinfect with carbendazim, then soak for 5 minutes with NAA diluted with water 500 times;

[0015] B. Colonization of isolated materials: insert the aforementioned pretreated isolated materials into the perlite matrix, and the isolated materials penetrate into the matrix by 3 to 5 cm, subject to non-overlapping;

[0016] C. Management of rooting period of isolated materials: Control the environmental conditions of plant growth through the automatic control system. The environmental control parameters are light intensity 7Lux, light time 12 hours / day, ...

Abstract

The invention belongs to plant non-test tube rapid propagation technology, and relates to a rapid propagation method for cajuput seedlings. The method comprises the following steps: A, the selection and pre-treatment of in-vitro materials: selecting stem buds from sprouts on stolons of cajuput seedlings, disinfecting incisions with carbendazim, and soaking in naphthylacetic acid; B, the field planting of the in-vitro materials: inserting the in-vitro materials into a pearlstone substrate; C, the rooting period management of the in-vitro materials: controlling the plant growing environmental condition through an automatic control system, from the beginning of the budding of a new root, spraying a nutrient solution once per 24 hours until the length of the new root is 3-5 cm through visual inspection; D, the hardening-seedling period management of the in-vitro materials: entering the nursery stock period after detecting that 1-2 leaves are grown at the upper parts of the in-vitro materials; E, the nursery stock period management: transplanting into a cultivation container or a cultivation ground bed having the conventional cajuput cultivation soil, so that commercial seedlings can be obtained after 8-10 days. According to the invention, the propagation speed and propagation survival rate are greatly improved, and the rapid propagation method is more suitable for the industrial implementation of large-scale rapid seedling culture.

Description

technical field [0001] The invention belongs to the non-test tube rapid propagation technology of plants, and relates to a rapid propagation method of eucalyptus seedlings. Background technique [0002] Existing eucalyptus seedling breeding methods mainly contain tissue culture technology and traditional branch cutting technology. However, the cutting propagation cycle is long, the survival rate is low, and it is difficult to achieve large-scale seedling cultivation. Tissue culture technology is used to cultivate non-toxic (first-generation seedlings), which is only suitable for scientific experiments, and is expensive and difficult to produce on a large scale. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rapid breeding method for eucalyptus seedlings that can greatly improve the breeding speed and breeding survival rate and is suitable for large-scale seedling breeding. [0004] The rapid breeding method ...
