Problems solved by technology

Existing artificial mechanical damage promotes the production of gum from sweetgum gum, which seriously affects the normal growth and future wood utilization of sweetgum gum due to large-scale damage to the external bark and surface xylem of the tree
There is currently no way to chemically stimulate sweetgum to produce resin

Embodiment 1

[0025]In May, July and September 2010, lanolin containing 1%, 2% and 5% mass concentration of methyl jasmonate, ethephon and ethephon-methyl jasmonate (1:1 mixture) , respectively treat the liquidambar of group A, group B and group C, and process the liquidambar of group D with lanolin without any reagent at the same time, and apply the reagent on the surface of the liquidambar trunk to form a 3mm thick, 3cm high Coating units, each coating unit is spaced 15cm apart ( Figure 10 B). As of October 2010, naked eye observation showed that there was no glue flow in group A treated with methyl jasmonate and group D as a comparison group, and there was glue flow in group B treated with ethephon and group C treated with mixed reagents , and through observation, it was found that there were more gums in the treated parts in May, and the trunks were mostly soaked by gums, with the special fragrance of sweetgum gum.

[0026] The samples treated with 1%, 2%, and 5% mass concentrations ...

Embodiment 2

[0055] After mixing methyl jasmonate and ethephon at a mass ratio of 1:1, the mixture is added to lanolin at a mass ratio of 1%, and then coated on the surface of sweetgum tree trunks from May to July, Coating units 3mm thick and 3cm high were formed with 30cm intervals between each coating unit. Observation with the naked eye showed that there was obvious gum flow in the coated area, and it was found that the amount of gum was the largest in the part treated in May, and the trunk was soaked by the gum, with a special fragrance of sweetgum gum.

Embodiment 3

[0057] After mixing methyl jasmonate and ethephon at a mass ratio of 1:1, the mixture is added to lanolin at a mass ratio of 5%, and then coated on the surface of sweetgum tree trunks from May to July, Coating units of 3 mm thick and 3 cm high were formed with 20 cm intervals between each coating unit. Observation with the naked eye showed that there was obvious gum flow in the coated area, and it was found that the amount of gum was the largest in the part treated in May, and the trunk was soaked by the gum, with a special fragrance of sweetgum gum.

Abstract

The invention discloses a chemical method for promoting sweetgum to produce lipid. After mixing methyl jasmonate and ethephon according to the mass ratio of 1: 1, the method comprises the following steps of: adding the mixture to wool oil according to the mass ratio of 1%-5%; coating the mixture on the trunk surface of the sweetgum between May and July to form coating units with the thickness of 3mm and the height of 3cm, wherein the coating units are spaced within 15-30cm at intervals. The chemical method for promoting sweetgum to produce lipid disclosed by the invention can treat the sweetgum by the methyl jasmonate and ethephon between May and July, can observe notable gummosis, and have most of gum passages with the most mature shape distributed in the xylem in May by section observation of the cross section of the treated sample between May and July; a trend that the higher the concentration and the more the number of the wound gum passages produced by the sweetgum are, the more the shape is mature cannot be appeared through the section observation of the cross section; and the reaction of the sweetgum treated at the concentration of 2% is notable.

Description

technical field [0001] The invention belongs to the technical field of chemically stimulating fat production in forest trees, and in particular relates to a chemical method for promoting fat production from sweetgum gum. Background technique [0002] Liquidambar formosana belongs to the tree species of the genus Liquidambar (Liquidambar L.) belonging to the HAMAMELIDACEAE R.Br. subfamily (Subfam.LIQUIDAMBAROIDEAE Harms). After being traumatized by the outside world, sweetgum will flow out gum. After collection and processing, it can be made into commercial glue, commonly known as sweetgum resin and white gum. China has recorded the use of sweetgum resin since ancient times. For example, in "Tang Materia Medica", Su Jing said, "Famacea can be found in all mountains. The tree is tall and the leaves are triangular. The tree is cut in May and the resin is harvested in November." . Liquidambar resin has an elegant and long-lasting aroma, which can be used to deploy a variety of...
