Problems solved by technology

[0004] At present, there are a small number of methods to quickly promote the formation of Dalbergia Dalbergia in production, such as mechanical trauma and smearing chemical reagents on the trunk, and even reports that ethephon promotes the formation of Dalbergia Dalbergia. Generally not high, the effect is only limited to the small area of ​​the trunk treatment part, the yield of the obtained balm is less, and it is impossible to realize large-scale standardization and commercial production, and there is no report about the method of quickly promoting the whole body of Dalbergia balsamic tree.

Embodiment 1

[0029] In June, 5-year-old Dalbergia japonica saplings were selected as materials, and three holes with a diameter of 1 cm and a horizontal depth of about 2 / 3 of the trunk were drilled with an electric drill at an angle of 120° at an angle of 45° downward on each tree trunk. Form a "three-hole interconnected structure", and then use a 5mL syringe to inject 1% ethephon (ETH) into the hole in portions to inject 1% methyl jasmonate (MeJA), salicylic acid (SA) and Abscisic acid (ABA) was used as the control group, and about 100 mL was injected into each tree for each treatment. At this time, the leaves of the tree body showed a severe wilting state. After injection, the hole is sealed with a cork. After 6 months of treatment, harvest and dissect the tree body, according to figure 1 Measure the size of the discoloration range, and the reddish-brown xylem is the fragrance. After being treated with ethephon induction reagent for 3 months, the collected samples ( figure 2 ), the p...

Embodiment 2

[0034] Taking the injection in June as the test group, and taking the injections in January, March and September as the control group, select 5-year-old Dalbergia saplings as materials, and use an electric drill to incline at 1m of the trunk of each tree at an angle of 120°. Drill three holes with a diameter of 1 cm and a horizontal depth of about 2 / 3 of the trunk at a downward angle of 45° to form a "three-hole interconnected structure", and then use a 5 mL syringe to inject 1% ethephon (ETH) into the holes in batches , A total of about 100 mL was injected per tree. After injection, the hole is sealed with a cork. After 6 months of treatment, the trees were harvested and dissected, and the reddish-brown xylem was baldwood. The results showed that the average longitudinal discoloration area injected in June was 685.3cm 2 , while the longitudinal discoloration areas of the control group injected in January, March and September were only 278.32, 318.96 and 449.20 cm 2 , that ...

Embodiment 3

[0036] Select 6-year-old Dalbergia saplings as materials, and use an electric drill to drill 3 holes with a diameter of 1 cm and a horizontal depth of about 2 / 3 of the trunk at an angle of 120° at every 120° angle on the trunk of each tree, and drill 3 holes with a diameter of 1 cm and a horizontal depth of about 2 / 3 of the trunk to form a "three hole interconnected structure", and another part of the sample plants only injected into one hole, taking the single hole injection as the control group, and then injected the concentration of 1% ethephon (ETH) into the hole with a 5mL syringe, each treatment of each tree A total of about 100 mL was injected, and at this time the leaves of the tree were in a state of severe wilting. After injection, the hole is sealed with a cork. After 6 months of treatment, the trees were harvested and dissected, and the reddish-brown xylem was baldwood. The results showed that the horizontal and vertical discoloration areas of the test group injec...

Abstract

The invention discloses a method for rapidly promoting the whole-tree "heartwood formation" of the Dalbergiaodorifera T.Chen, and belongs to the field of biotechnology. By the use of the method of theinvention, almost the whole tree (the whole trunk and large-diameter branches) of the xylem of the tree body is changed into red-brown, and the oil content and composition of the discolored xylem aredetected to both reach the level of natural Dalbergia odorifera. The method of the invention has the characteristics of simple process and convenient operation, the selected inducing agent is naturaland pollution-free, the application method is scientific and novel, the inducing effect is remarkable, the whole-tree "heartwood formation" of the tree body is basically realized, less time is consumed, and the whole-tree "heartwood formation" of the Dalbergiaodorifera T.Chen can be quickly promoted in a short time. The method can be used for large-scale standardization and commercial production,can effectively alleviate the contradiction between the supply and demand markets of the Dalbergia odorifera, is beneficial to the protection, development and utilization of the Dalbergiaodorifera T.Chen resources, and has important economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a method for rapidly promoting the "fragrance" of Dalbergia balata throughout the body, in particular to a method for rapidly promoting the "fragrance" of Dalbergia balata throughout the body by using a plant growth regulator. Background technique [0002] Dalbergia dorifera T.Chen, also known as Hainan huanghuali, belongs to the plant of the genus Dalbergia (Papilionaceae) and is a semi-deciduous tree species. Dalbergia Dalbergia was originally produced in Hainan, and since the middle of the last century, it has been introduced to Guangdong, Guangxi, Fujian, Sichuan and Yunnan. It is now a national second-class protected plant. Dalbergia Dalbergia is well-known for its high-quality heartwood and its high price. Its heartwood is reddish-brown, hard in texture, resistant to moisture and corrosion, stable in wood, elegant and clear in pattern, like flowing clouds and flowing water, and ...
