Embodiment Construction

[0016] a. Establish greenhouses and seedbeds

[0017] A greenhouse simulating the microenvironment of tissue culture test tubes is composed of an arch 3, a mist spray nozzle 4 for spraying water to cool down, a supplementary light 5, and a water pipe 8 with a timer 6 and a solenoid valve 7. The arch frame is covered with micro-membrane to form the whole arch shed, and the height of the arch shed is 70 cm. A full-angle fill light 5 is added to the shed, and the light saturation point is 40000 Lux. The seedbed is composed of a special seedling tray 1 for forest trees and a perlite matrix 2 which are convenient for drainage. The seedbed is 1 meter wide, 3 meters long and 0.7 meters high.

[0018] b. Preparation of isolated materials and inorganic nutrient solution

[0019] The 4-6cm leafy plant section or one leaf and one bud of the Japanese red maple's semi-lignified young branches in the same year is used as the isolated material, sterilized, the morphological upper cut is s...

Abstract

The invention relates to a non-test tube rapid propagation method for Japanese red maple seedling, which comprises three steps of building a sun greenhouse and a seedling raising tray, preparing exsomatize material, and culturing seed seedling. The method has the beneficial technical effects that the speed of obtaining a complete regeneration plant is rapid and the propagating speed is rapid so that the seed seedling is multiplied quantitatively in short time; the ripening seed seedling has the high purity, does not have pests and has developed and complete root systems; green plantlets inoculated and cultured in the tray have the high purity and do not have pests; the separation of the virus-free seed seedling is propagated; the technology is particularly suitable for the situation that female parent material is few, a great amount of commercial seed seedlings are urgently needed, and the red maples need to be engrafted in the past. After multi-generation circulation technologies, the rootage time is greatly shortened, which is directly related to the childness or young nature of the plants which is aroused; the correct understanding and application of the rapid propagation technology has great significant for accelerating the expanding propagation of the new species and reducing the cost of the seed seedling.

Description

technical field [0001] The invention belongs to the field of cultivation technology, and more specifically relates to a non-test-tube rapid propagation method for Japanese red maple seedlings. Background technique [0002] Japanese red maple (acer palmatum atropurpureum), also known as Japanese red ribbon, is a general name for the red Acer palmatum from Japan. At present, the main species introduced and cultivated in my country is the blood red Acer palmatum, which belongs to the small deciduous tree of the family Acer palmatum. The blade tip is sharp, the leaf edge is sawtooth, and the leaf color is purple or red. It is a famous foliage tree species with excellent garden applicability and high economic value. Gardens and tall deciduous trees form a mixed forest, and are also good materials for making bonsai potted plants. [0003] The existing propagation methods of Japanese maple are mainly seed propagation and grafting. Seed propagation is limited by seasons, the probab...
