Problems solved by technology

However, the traditional cutting technology has strict requirements on the cuttings, the survival rate of hard branch cuttings is low, and a large amount of manpower is required to build the ear picking nursery, which greatly increases the cost of seedling cultivation; and the survival rate of cuttings is greatly affected by many factors such as management and natural environment. , the stability of the survival rate is not strong, and the effect is not good; in addition, the traditional cutting propagation method uses soil, fine sand, etc. as the substrate, and it is difficult to observe its rooting status and control the nutrient ratio after cutting

Embodiment 1

[0034] A method for hydroponic cutting propagation of an endangered plant Narrow Leaf Slope Base, including cutting device preparation, nutrient solution preparation, cuttings collection and processing, rooting agent soaking, cutting and post-cutting management, the main operations are as follows:

[0035] (1) Cutting device preparation: use a plastic box with a length × width × height of 35.2cm × 25cm × 9.5cm as the culture container, and use a 1.5cm thick pearl cotton board as the cutting board. The length and width of the container is 5cm, and cutting holes are made with a puncher. The cutting hole diameter is 0.5cm, and the interval between each cutting hole is 5cm. Use angle steel to build 5 layers of glass with a length of 200cm and a width of 100cm as a culture frame, and use 1:24 bromogermine aqueous solution to wipe The surfaces of culture containers, cutting boards and culture racks should be sterilized and placed in a room equipped with curtains, air conditioners and...

Abstract

The invention discloses a hydroponic cutting propagation method for the endangered plant Antophthora angustifolia. Collect 1-2-year-old hard branches as cuttings, soak them in 600-800 mg / L GGR rooting agent for 1-2 hours, and insert them into cutting boards. Place it in a culture container filled with nutrient solution, put the culture container on the culture rack and cultivate the tube until it takes root. The special nutrient solution prepared by the present invention can effectively promote the rooting of the cuttings of S. angustifolia, and the methanol crude extract of S. sylvestris is added to the nutrient solution, which has a certain inhibitory effect on molds, and effectively avoids the ear growth caused by mold. The rooting speed is fast, the rooting rate is high and stable, and the nutrient solution is used as the medium for hydroponic cutting seedlings, the environment is stable and controllable, the nutrition is balanced, the seedlings grow robustly and consistently, the management is simple, and it can save a lot of cost. It has good application value and Practical significance.

Description

technical field [0001] The invention belongs to the technical field of tree seedling cultivation, and relates to a method for hydroponic cutting propagation of an endangered plant. Background technique [0002] Hopea chinensis Hand.-Mazz. belongs to the genus Hopea of ​​the family Dipterocarpaceae. It is an evergreen tree. It is a rare and endangered tree species unique to Guangxi, and one of the representative tree species in the tropical evergreen monsoon forest in the north and south of Guangxi. First, it is of great value to the study of tropical rainforest flora composition, geographical distribution and ecological habits. At the same time, its material is hard and its corrosion resistance is extremely strong. It is called "Wannian Wood" and can be used as military industry, machinery and high-end furniture. Narrow leaf slope barrier belongs to the residual species of the Tertiary period, distributed in the "refuge" formed by local terrain, originally distributed in th...
