Problems solved by technology

The method of tissue culture and rapid propagation of Eucalyptus aeruginosa has been studied since the 1980s. Up to now, due to the key technologies such as preventing explant browning and low rooting rate have not achieved good results, it has been difficult to achieve industrial seedling cultivation of Eucalyptus aeruginosa.

Embodiment Construction

[0020] 1. Excellent individual selection

[0021] Select individuals without pests and diseases with a eucalyptol content of more than 60% in the eucalyptus leaf oil of a single plant in the Eucalyptus fornica seedling forest as excellent trees.

[0022] 2. Tissue culture rapid propagation

[0023] 2.1. Collection of explants

[0024] On the basis of the selection of excellent individual plants, in the spring when the rain is sufficient and the temperature rises, circumcision (2 / 3 of the circumference of the tree) is carried out at an excellent tree about 30 cm from the ground, and the cut reaches the phloem. When the sprouts grow to 30-40cm, they are collected and inoculated in the afternoon on a sunny day.

[0025] 2.2. Disinfection of explants

[0026] After removing the leaves from the harvested branches, clean the dirt and other pollutants attached to the surface of the branches with clean water, then scrub with a soft brush dipped in soap powder or detergent, and then...

Abstract

The invention provides a method for rapidly reproducing protruding eucalyptus through tissue culture, which comprises the steps that: excellent tree bodies are selected as explants which are then collected and sterilized; initial culture, multiplication culture and rooting culture are carried to stem sections; then the seedlings adopt seedling adaptation, transplantation from bottles and seedling management. The method of the invention can increase multiplication coefficient of 3 to 5. The inheritable characters of the germchit of the protruding eucalyptus are stable, and the germchit of the protruding eucalyptus reaches improved variety and cloning, thus increasing the wood yield of an elemental area and promoting the ecological and economic benefits of the woods of the protruding eucalyptus.

Description

1. Technical field [0001] The invention belongs to forest tree tissue culture seedling raising technology in forestry science. 2. Background technology [0002] Eucalyptus exseta is an evergreen tree belonging to the Myrtle family, Eucalyptus. shape. It is native to the vast area with a width of 300km along the northeastern coast of Australia, and has been cultivated in my country for more than 100 years. Eucalyptus eucalyptus wood has a solid and elastic structure, dense texture, beautiful patterns, high strength, corrosion resistance and moisture resistance. It is an excellent material for construction, flooring and furniture. Eucalyptus aeruginosa has no strict requirements on site conditions, fast growth, strong germination, well-developed root system, and strong adaptability. It is a good tree species for building water source forests and soil and water conservation forests, and is also an excellent tree species for building short-cycle industrial raw material forests...
