Efficient cultivation method of camphor forest for oil use

Abstract

The invention discloses an efficient cultivation method of a camphor forest for oil use. The method comprises the steps of selection of nursery stocks, determination of site conditions, adoption of aplanting technique, density regulation, tree shape regulation, tending management, determination of a harvesting mode and the like. According to the method, clonal cutting container seedlings or tissue culture container seedlings are selected, and various parameter values of the nursery stocks are strictly controlled, so that the content of oil and linalool in camphor trees is ensured; through implementation of secondary seedling hardening, the survival rate of afforestation is greatly increased, and by adopting a rational close planting means, a plexiform tree shape regulation means, a meansof harvesting twice in one year and other technical means, the yield of the branches and leaves of the camphor trees is greatly increased. By means of the method, waste residues obtained through a linalool extraction process are also recycled as camphor planting fertilizer, the cost is reduced, and the environmental pollution caused by waste is reduced; meanwhile, camphor tree resources are rationally harvested, a predatory harvesting mode is avoided, and sustainable utilization of the camphor tree resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a high-efficiency cultivation method of a camphor tree leaf forest. Background technique [0002] Camphor tree (cinnamomum camphora) belongs to the genus Cinnamon of the family Lauraceae and is a national second-class protected plant. It grows well in deep, fertile and moist acidic or neutral yellow soil and red soil. It is not resistant to drought, barren and saline-alkali soil. It has strong resistance to sulfur dioxide, ozone, and smoke pollution, and can absorb a variety of toxic gases. It is mainly distributed in southern provinces such as Jiangxi, Guangxi, Guangdong, Hunan, Fujian, Guizhou, and Hainan. It is one of the important tree species of evergreen broad-leaved forests in subtropical regions of my country, and is also an important tree species for spice raw materials. Camphor tree mainly contains natural fragrance compounds such as linalool, saf...

Problems solved by technology

However, the traditional camphor tree planting has not done a good job in the breeding of good varieties, resulting in many camphor trees planted with low oil content and less linalool content, which greatly increases the cost of processing and separating linalool, seriously affecting economic benefits.

Although natural linalool is mainly extracted from the leaves of camphor trees, in order to increase the production of linalool, many natural linalools are obtained by unordered digging of camphor trees, using their branches, leaves, trunks, roots, etc. as raw materials Primary linoleum oil is obtained by steam distillation, which is a predatory destruction of camphor tree resources
