Description

Technical Field

[0001] This invention belongs to the field of agarwood tree wound-making technology, specifically involving a method for controlling the amount of wounds in agarwood trees through comprehensive management. Background Technology

[0002] Agarwood is a rare resource in the fields of fragrance and medicine, possessing both high economic and cultural value. With the continuous growth of market demand, the supply and demand contradiction of high-quality agarwood is becoming increasingly prominent. However, wild agarwood trees are endangered due to over-harvesting and have been listed in the CITES Convention for protection. The natural resin formation rate is less than 1% and the cycle takes decades, which cannot meet the demand for large-scale supply. Artificial cultivation has become the core path for the sustainable development of the industry.

[0003] Current artificial agarwood production technology still faces many problems. For example, existing methods such as physical trauma, biological inoculation, and chemical stimulation can induce agarwood production in trees, but the yield is not high. Furthermore, physical trauma methods (such as drilling holes and burning) result in limited agarwood formation area and uneven quality. Although biological inoculation technology shortens the cycle, it does not provide sufficient aroma and flavor. Some chemical stimulation methods also have issues with toxic residues and environmental pollution. Summary of the Invention

[0004] This invention provides a method for controlling the amount of damage to agarwood trees through comprehensive management, in order to solve at least one of the following technical problems: existing agarwood making techniques focus too much on "inducing fragrance" and "forming fragrance", which leads to a disconnect between "tree cultivation" and "forming fragrance" of agarwood trees. The weakening of the tree vigor leads to a decline in the amount and quality of agarwood, which is not sustainable.

[0005] This invention achieves low-damage agarwood formation technology by comprehensively managing and controlling the amount of damage, optimizing the tree's growth state, improving the success rate and stability of agarwood formation from the root, and ensuring the natural aroma and core effective component content of agarwood.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A method for controlling the amount of trauma to agarwood trees and creating fragrance, wherein the agarwood tree is divided into several fragrance-creating zones from bottom to top along the trunk; and an interval is set when each fragrance-creating zone is used for trauma-creating fragrance.

[0007] Furthermore, the interval is ≥2 months.

[0008] Furthermore, the interval is 3-6 months.

[0009] Furthermore, the number of fragrance-producing zones in a single agarwood tree is 2-6.

[0010] Furthermore, the height of the fragrance-making area is 80-150cm; the bottom of the first fragrance-making area is 20-30cm above the ground, and the vertical distance between adjacent fragrance-making areas is 20-50cm.

[0011] Furthermore, the wound-induced fragrance production is achieved by drilling, with the depth of the drilled fragrance-producing holes ≤ 1 / 3 of the trunk diameter at breast height.

[0012] Furthermore, the fragrance-generating holes are arranged in groups of 2-5 horizontally spaced holes; the fragrance-generating area is provided with several groups of fragrance-generating holes at intervals along the height range of the circumference of the agarwood tree trunk; the number of fragrance-generating hole groups on the same horizontal plane is 1-2 groups.

[0013] Furthermore, nitrogen fertilizer should be discontinued on agarwood trees 8-14 months before the wound produces agarwood; potassium fertilizer should be applied to agarwood trees 0.3-0.6 kg / tree 1-4 months before the wound produces agarwood.

[0014] Furthermore, the agarwood tree must be at least 5 years old and / or have a diameter at breast height (DBH) of at least 10 cm.

[0015] Furthermore, when drilling for incense production, a 12-14mm drill bit is used for trees aged 5-10 years, a 14-16mm drill bit is used for trees aged 10-20 years, and a 16-18mm drill bit is used for trees aged over 20 years.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. A single agarwood tree is divided into multiple agarwood-producing zones. There is an interval between the wounds and agarwood-producing zones. The interval allows the agarwood tree to heal its wounds and begin to form agarwood. This avoids excessive damage to the tree at one time, which would lead to a decline in growth and affect the success rate and stability of agarwood formation.

[0017] 2. The depth of the agarwood-forming hole is ≤1 / 3 of the trunk diameter at breast height, which avoids the problem of the existing agarwood trees having a larger drilling depth (2 / 3 of the trunk diameter at breast height), which damages the heartwood of the tree, disrupts its nutrient transport path, and thus leads to less resin production and poor quality.

[0018] 3. Applying potassium fertilizer to agarwood trees before wound formation can promote their growth, enhance their resistance, and prevent the quality of agarwood formation from being affected by the weakness of the tree.

[0019] This invention employs controlled trauma-based agarwood production, which has the advantages of expanding the agarwood formation area, controlling the agarwood formation cycle, and having a high yield per plant and a high proportion of high-quality agarwood. Attached Figure Description

[0027] To facilitate a better understanding of the present invention, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the scope of protection of the present invention, but do not limit the scope of protection of the present invention.

[0028] Example A method for controlling the amount of trauma to agarwood trees and creating fragrance, wherein the agarwood tree is divided into several fragrance-creating zones 2 along the trunk 1 from bottom to top; and an interval is set when each fragrance-creating zone 2 is used for trauma-creating fragrance.

[0029] The interval is ≥2 months.

[0030] The interval is 3-6 months.

[0031] The number of fragrance-producing zones 2-6 per agarwood tree.

[0032] The height of the fragrance-making area 2 is 80-150cm; the bottom of the first fragrance-making area 2 is 20-30cm above the ground, and the vertical distance between adjacent fragrance-making areas 2 is 20-50cm.

[0033] The method of creating fragrance through wounds involves drilling holes, with the depth of the three holes being ≤1 / 3 of the trunk diameter at breast height.

[0034] A group of 2-5 horizontally spaced fragrance-generating holes 3 forms a group of fragrance-generating holes 4; several groups of fragrance-generating holes 4 are spaced apart along the height range of the trunk of the agarwood tree in the fragrance-generating area 2; the number of groups of fragrance-generating holes 4 on the same horizontal plane is 1-2.

[0035] Stop applying nitrogen fertilizer to agarwood trees 8-14 months before wound formation; increase potassium fertilizer application to agarwood trees by 0.3-0.6 kg / tree 1-4 months before wound formation.

[0036] Agarwood trees must be at least 5 years old and / or have a diameter at breast height (DBH) of at least 10 cm.

[0037] When drilling for incense, use a 12-14mm drill bit for trees aged 5-10 years, a 14-16mm drill bit for trees aged 10-20 years, and a 16-18mm drill bit for trees aged over 20 years.

[0038] Applying potassium fertilizer to agarwood trees before trauma helps enhance their resistance and promotes branch growth. Potassium sulfate (K2O 50%) can be used as the potassium fertilizer. When applying potassium fertilizer, you can decide whether to apply phosphorus fertilizer based on the specific condition of the plant (such as if the trunk is weak). If you need to apply phosphorus fertilizer, you can use it together with potassium fertilizer in a 1:1 weight ratio. You can use superphosphate (P2O5 12%–18%) + potassium sulfate (K2O 50%).

[0039] The main methods of agarwood production in this application include dividing the agarwood production area, controlled wound agarwood production, applying potassium fertilizer and watering before agarwood production, and maintaining the wounded area (moisturizing, sun protection, insect prevention, etc.) after the agarwood production holes are opened. The agarwood production time can be determined according to quality requirements, and agarwood trees with an age of 8 years or more are generally preferred. The depth of the drilled agarwood production holes is limited to ≤1 / 3 of the trunk diameter at breast height, so as not to damage the pith, thus preserving the core function of the heartwood in transporting water and nutrients, causing less damage to the tree, maintaining its good vitality, and allowing it to recover quickly during the interval after drilling.

[0040] Technical Principle: This application divides a single agarwood tree into several agarwood-producing zones, with each zone controllingly producing agarwood at intervals. The interval is at least 2 months. During this period, the injured agarwood tree has initially healed (gradually healing from the inside out) and has begun to produce agarwood. Then, the next agarwood-producing zone is subjected to wound agarwood production. This avoids the tree from declining in growth due to excessive damage at once, and helps the tree to continuously accumulate nutrients during the interval, storing energy for agarwood production in other subsequent zones. This achieves the simultaneous advancement of tree cultivation and agarwood production, improving the success rate and stability of agarwood production, and resulting in higher quality agarwood.

The top of the fragrance area is 540cm from the ground.

[0088] Comparative Example 1 Same as Example 5, except that the interval is 0 months, that is, all 3 fragrance-making areas are drilled and wound for fragrance making.

[0089] Comparative Example 2 Same as Example 5, except that the interval is 1 month.

[0090] Comparative Example 3 Same as Example 5, except that the interval is 7 months.

[0091] Comparative Example 4 Same as Example 5, except that the depth of the fragrance-making hole 3 is 2 / 3 of the trunk diameter at breast height.

[0092] Comparative Example 5 Same as in Example 5, except that the fragrance-making hole 3 is a through-hole (drilled horizontally through the trunk).

[0093] Comparative Example 6 Same as Example 5, except that: 3 months before the agarwood tree was wounded and began to produce fragrance, a compound fertilizer was applied to the agarwood tree with a total nutrient content of 35%, and the ratio of N, P2O5 and K2O was 15-15-15, at 0.5 kg / tree.

[0094] When performing trauma treatments in the above groups, the drilling should be completed within 3 days.

[0095] Experiment 1 1. Trial period: January 2017 - December 2024 2. Experimental location: The planting base in Qiongzhong, Hainan Province, has 20-year-old Aquilaria sinensis trees with a trunk diameter of 35-40cm. Plants with problems such as weak growth, thin trunks, sparse branches and leaves, serious pests, and trunk rot were removed. 720 healthy Aquilaria sinensis trees suitable for making incense were selected and divided into 6 groups with 120 trees in each group.

[0096] 3. Wound Aroma The control group was treated using the aforementioned control group method, while the other 5 groups were treated using the methods described in Examples 1-5 of this invention. All drilling was done with a 17mm drill bit. Apart from the differences mentioned above, the management measures such as watering and pest control were the same for both groups.

[0097] 4. Agarwood Extraction Results: The agarwood formation period for all groups was uniformly set at 8 years. After the period expired, each plant was girdled to extract agarwood. The following statistics were recorded for each group: number of dead plants, number of agarwood-producing plants, minimum yield per plant (excluding dead and non-agarwood-producing plants), maximum yield, and average yield (calculated based on the total number of plants in each group).

[0098] Soil samples were taken and tested in accordance with T / SSSC 016—2025 "Technical Specification for Monitoring Microplastics in Soil Environment". Common plastic pollutants such as polyethylene, polypropylene, and polystyrene were not detected.

[0099] The results for each group are shown in Table 1.

[0100] Table 1. Summary of data for each group

[0101] As can be seen from the comparison of the data of Examples 1-5 and the control group in Table 1, the control group used perforation drilling to produce agarwood, and the excessive number of agarwood-producing areas on the trunk damaged the tree's nutrient supply system, leading to nutrient imbalance and, in severe cases, the death of some trees; at the same time, due to the weakened tree vigor, the average amount of agarwood produced per tree was also significantly less than that of this application.

[0102] In Examples 3 and 4 of this application, one and two plants died, respectively. This may be due to the excessive number of fragrance-producing areas and insufficient recovery time. Furthermore, the interval between examples was 6 months, while the interval between examples 3 and 4 months. This difference in interval may explain why there were more plant deaths in Example 3 than in Example 4. Data from Examples 1-5 show that the minimum yield, maximum yield, and average yield per plant of the method of this invention are all significantly higher than those of the control group. This indicates that the method of this invention, through a combination of measures such as batch fragrance production and limiting the depth of fragrance-producing holes, allows for better recovery time for plant trauma, reduces damage from sequential batch fragrance production, reduces or avoids plant mortality, and results in significantly higher yields.

[0103] Experiment 2 1. Trial period: January 2018 - December 2025 2. Experimental site: The planting base is located in Qiongzhong, Hainan. The Aquilaria sinensis trees at the base are 20 years old with a trunk diameter of 35-40cm. Plants with problems such as weak growth, thin trunk, sparse branches and leaves, serious insect infestation, and trunk rot were removed. 420 healthy Aquilaria sinensis trees suitable for making incense were selected. They were divided into 7 groups according to Example 5 and Control Groups 1-6, with 60 trees in each group.

[0104] 3. Wound-induced fragrance creation: Wound-induced fragrance creation was carried out according to Example 5 and Comparative Examples 1-6, using a 17mm drill bit. Except for the differences mentioned above, the management measures such as watering and pest control were the same for each group.

[0105] 4. Results of fragrance collection The resin formation cycle for each group is 8 years. After the cycle expires, the resin-forming area is confirmed to be dark brown before girdling and extracting the resin. The number of dead plants, the number of resin-forming plants, the minimum yield per plant (excluding dead and non-resin-forming plants), the maximum yield, and the average yield (calculated based on the total number of plants in each group) are recorded for each group.

[0106] Soil samples were taken and tested in accordance with T / SSSC 016—2025 "Technical Specification for Monitoring Microplastics in Soil Environment". Common plastic pollutants such as polyethylene, polypropylene, and polystyrene were not detected.

[0107] The results for each group are shown in Table 2.

[0108] Table 2 Summary of Data for Each Group

[0109] As can be seen from Example 5 and Comparative Examples 1-3, setting a reasonable interval period during the wound-induced resin production process has a significant effect on tree recovery. The interval between resin production in each resin production zone provides the tree with time to rest and recuperate, resulting in the better single-tree resin production and average resin production of Example 5 compared to Comparative Examples 1-3. Moreover, Comparative Example 1 did not have an interval period, which led to the death of 2 plants. Comparative Example 2 had an interval period of 1 month, and its minimum yield, maximum yield, and average yield per tree were all significantly higher than those of Comparative Example 1, indicating that setting an interval period has a positive effect. Although the maximum yield and average yield per tree of Comparative Example 3 were higher than those of Example 5, the interval period was 7 months, which was a long cycle and the effect was not obvious.

[0110] As can be seen from Example 5 and Comparative Examples 4-5, the depth of the agarwood-producing hole has a significant impact on tree growth. The opening of the agarwood-producing hole disrupts the vascular bundles and affects the supply of nutrients, resulting in the lowest, highest, and average agarwood production per plant in Comparative Examples 4-5 being lower than that in Example 5. However, due to the 6-month interval, the plant growth has recovered to some extent, so the agarwood production is still significantly higher than that in Comparative Example 2.

[0111] As can be seen from Example 5 and Comparative Example 6, the present invention stops applying nitrogen fertilizer one year before wound formation and increases potassium fertilizer three months before wound formation, which helps to strengthen branches and trunks. By stopping the application of nitrogen fertilizer, the growth of leaves is controlled, and excessive nutrient consumption is avoided. As a result, the average amount of agarwood produced per plant in Example 5 is better than that in Comparative Example 6, while in Comparative Example 6, there was a case where one plant did not produce agarwood.
