Cirmamonun camphora clone scale fast propagation seedling-breeding method

Abstract

The invention discloses a clonal scale rapid seedling cultivation method for Borneol Cinnamomum camphora, which comprises the following steps; soil with the ph value ranges from 5.5 to 7.0 is chosen; land is prepared and ridges are formed; 0.5% potassium permanganate solution is used for the disinfection treatment of the soil on the surface of the ridges; annual semi lignified or 80% lignified strong and healthy branches from one year to three years old Borneol Cinnamomum camphora are chosen as cuttings; 1 / 3 to one robust leaf is reserved on the cutting; a horse ear shaped oblique incision is cut at the upper end; the lower end is transversely cut; the upper part of the cutting is processed by dipping quickly in 1000ppm indole butyric acid solution, then processed by 600 times to 800 times mancozeb solution, and sterilization of the cuts of branches and leaves is performed; cutting is performed vertically; after cutting, the cuttings are closely covered by an agricultural film; heat insulation, moisture retention, foliage dressing, seedling adaptation and transplanting are carried out; after tending management, seedlings can go out of nursery. The Borneol Cinnamomum camphora seedlings bred by the method of the invention has the advantages of improved clone cutting rooting survival rate, robust seedlings, fast growth after forestation, and wide crown; after three years, forestation is realized, and fresh branches and leaves yield per mu is over 1000kg; therefore, the material for a large amount of natural borneol is ensured.

Description

technical field [0001] The invention relates to a method for growing seedlings of borneol camphor clones. Background technique [0002] In the 1980s, scientific and technical personnel of Xinhuang County Borneo Development Co., Ltd. of Hunan Province discovered a kind of Lauraceae plant rich in natural d-borneol components-borneol camphor [Cinnamonun Trew] in the virgin forest of Xinhuang County, Hunan Province. ]. After several years of research, the company's scientific and technical personnel invented the "extraction of D-borneol from camphor leaves" in 1992 and obtained the national invention patent in 1994. Natural d-borneol, also known as natural borneol, is native to the Sumatra Islands in Indonesia and is a crystallized product of steam distillation from the trunk and roots of Dipterocarpus [Dryobalanopsaromatica Gaertmer]. Its qi is fragrant, bitter, pungent and cool, and has medicinal functions such as clearing all orifices, dispersing stagnation of fire, reducin...

Problems solved by technology

At present, this dipterocarp tree is almost exhausted, and many countries mainly use artificial synthetic chips to replace natural borneol, but the medicinal effect is far inferior to natural borneol, and it contains isoborneol which is harmful to human body
