Embodiment 1

[0034] Choose a 5-year-old white wood incense tree, and use an electric drill to drill the vertical trunk from a distance of 10cm from the ground. The diameter of the hole is 0.8cm, and the depth of the hole is 2cm. Six holes are drilled in a spiral arrangement. Prepare the inducer, which contains strong oxidant peracetic acid 0.15% and hydrogen peroxide 0.001%, fungal fermented polysaccharide pullulan 0.005%, inorganic salt sodium chloride 0.006%, plant hormone salicylic acid 0.003%- 4000mL of aqueous solution. Inject the inducer into the drilled tree trunk hole with a tree nutrient needle syringe, and transport the inducer to the tree body of the Acacia japonica through plant transpiration, and seal the hole with wooden nails after the infusion to prevent the inducer from flowing out and The rain washes over. Beginning 3 days after the infusion, some leaves of the Acacia japonica began to fall, and after one month, most of the leaves fell, leaving only a few leaves at the t...

Embodiment 2

[0040] Choose a 6-year-old white wood fragrance tree, and use an electric drill to drill the vertical trunk from a distance of 10cm from the ground. The diameter of the hole is 0.3cm, and the depth of the hole is 1cm. Drill 4 holes in a spiral arrangement. Prepare the inducer, which contains 0.06% of strong oxidizing agent hydrogen peroxide, 0.006% of fungal fermented polysaccharide yeast β-glucan, 0.005% of inorganic salt calcium chloride, and 2500 mL of aqueous solution of 0.002% ethephon in terms of mass percentage. Inject the inducer into the drilled tree trunk hole with a tree nutrient needle syringe, and transport the inducer into the tree body of the white wood by using the transpiration of the plant. After the infusion is completed, seal the hole with a wooden nail to prevent the inducer from flowing out and rainwater scour. Beginning 3 days after the infusion, some leaves of the Acacia japonica began to fall, and after one month, most of the leaves fell, leaving only ...

Embodiment 3

[0042] Choose a 7-year-old white wood fragrance tree, and use an electric drill to drill the vertical trunk from a distance of 10cm from the ground. The diameter of the hole is 0.6cm, and the depth of the hole is 3cm. Eight holes are drilled in a spiral arrangement. Prepare the inducer, which contains 0.22% of strong oxidizing agent peracetic acid, 0.002% of fungal fermented polysaccharide yeast β-glucan and 0.006% of pullulan polysaccharide, 0.015% of inorganic salt ferric chloride, plant hormone jasmonate A 5000 mL of aqueous solution of 0.001% ester, 0.003% ethephon and 0.004% salicylic acid. Inject the inducer into the drilled tree trunk hole with a tree nutrient needle syringe, and transport the inducer into the tree body of the white wood by using the transpiration of the plant. After the infusion is completed, seal the hole with a wooden nail to prevent the inducer from flowing out and rainwater scour. Beginning 3 days after the infusion, some leaves of the Acacia japo...

Abstract

The invention discloses an inducer for promoting agilawood formation of agilawood trees, and belongs to the technical field of biology. The inducer comprises a strong oxidant, fungal fermentation polysaccharide, inorganic salt and plant hormone. The inducer is injected into a trunk of an agilawood tree by an injection method, and then brown and yellowish-brown color-changing xylem in the trunk is cut and dried in the shade to obtain the agilawood. Components of an existing agilawood inducer are adjusted, formic acid, acetic acid and the like in a traditional agilawood inducer are replaced with a strong oxidant, molecular oxygen is generated after the agilawood inducer is injected into a tree body, and the strong stimulation effect on the tree body is achieved. The fungal fermentation polysaccharide serving as a plant stimulator can stimulate an agilawood tree to generate a stress reaction, so that resin secretion is facilitated, the yield of agilawood is increased, the content of an alcohol-soluble extract, the relative content of agarotetrol and the total relative content of sesquiterpenoids and 2-(2-phenethyl)-chromone compounds are increased, and the quality of agilawood is improved. The inducer has good economic benefits and ecological benefits.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to an inducer for promoting the formation of agarwood. Background technique [0002] Agarwood is a resinous wood formed by the secretion of resin from the xylem of Aquilaria or Gyrinops trees of the family Thymelaeaceae after being damaged by nature or man-made. It is a traditional precious medicinal material in my country and a rare spice in the world. The medicinal effects of stopping vomiting, appreciating qi and relieving asthma are known as "gold in medicine" and "king of fragrance". Agarwood integrates the value of medicine, spice, religious culture and collection, etc., and has profound historical and cultural value and modern economic value. [0003] Aquilaria sinensis (Lour.) Gilg, also known as Aquilaria sinensis, belongs to the genus Aquilaria in the family Daphneaceae. It is the only source plant of Chinese traditional Chinese medicine Aquilaria sinensis, and has...
