Description

Technical Field

[0001] The invention relates to the technical field of tree maintenance, in particular to a bottle-inserted self-flowing dry-filling bottle capable of preventing resin back-sucking. Background Art

[0002] Pine wilt disease is a forest disease with a very high global mortality rate caused by the pine wood nematode (Bursaphelenchus xylophilus), known as the "cancer of pine trees". Pine wood nematodes are a parasite that is highly harmful and difficult to control. The pine wood nematode disease it causes is also highly hidden, and it causes rapid death after an outbreak. It has the characteristics of rapid spread, difficulty in prevention and control, rapid onset, and severe harm. Therefore, there is an urgent need to develop highly effective nematicides for the prevention and control of pine wood nematode disease. At present, the chemical pesticides on the market used for the prevention and control of pine wood nematode disease mainly include emamectin benzoate, avermectin, etc., which mainly enter the tree body by injection into the trunk, thereby protecting the pine trees.

[0003] Injection-drying is a method of injecting pesticides into the wood of trees using special tools, using the upward pulling force generated by the tree during transpiration, and relying on the autonomous conduction of the pesticide in the tree body to prevent and control tree diseases and insect pests. This technology can reduce the drift of pesticides in nature and achieve the prevention and control of diseases and insect pests.

[0004] At present, the main methods of trunk injection include the following: (1) drilling and injection. The main steps are to use a hand drill to drill a hole at the base of the trunk at an angle of 45° downward from the trunk, and then inject the diluted liquid medicine directly into the hole. However, this method has the problem of large holes and greater damage to the tree. (2) Injection of medicine into the trunk bottle. However, in southern China, such as Fujian and Guangdong, due to the high average annual temperature, the resin secretion of Masson pine is vigorous, causing resin reflux, resulting in the bottle body bursting, and the injection nozzle will be blocked by the resin, making it impossible to inject the medicine into the tree. (3) Minimally invasive precision injection technology. Although this method causes less damage to the tree, it has the problems of large needle loss, low injection efficiency and high cost. Therefore, in order to meet the current needs for efficient prevention and control of agricultural and forestry pests and diseases, there is an urgent need for a trunk injection device that can overcome the resin reflux, is efficient, simple to operate and low-cost. For this purpose, we propose a bottle-inserted self-flowing trunk injection bottle that prevents resin backflow. Summary of the invention

[0031] See attached Figure 1-4 As shown, a bottle-inserted self-flowing dry-filling bottle for preventing resin back-sucking comprises a bottle body 1 and a medicine injection nozzle 2, wherein the bottle body 1 comprises a bottle body 11 and a bottle cap 12, and the bottle cap 12 is detachably connected to the bottle mouth of the bottle body 11 by means of threads, snaps, etc.; the medicine injection nozzle 2 is a slender conical tube that is small at the top and large at the bottom, and the conical tube is open at both ends, and a plurality of through holes 21 are symmetrically provided on both sides of the medicine injection nozzle 2. In this embodiment, three through holes 21 are provided on each side of the medicine injection nozzle 2; the lower end of the medicine injection nozzle 2 is plugged and fixed to the medicine injection port of the bottle cap 12 (similar to the connection method between a needle tube and a syringe), and further, the medicine injection nozzle 2 and the medicine injection port of the bottle cap 12 can also be connected by means of threads, snaps, etc.

[0032] Furthermore, a horizontal piece 22 is provided at the lower end of the injection nozzle 2, and the long side of the horizontal piece 22 is parallel to the direction of the line connecting the through holes 21 on both sides at the same horizontal position, that is, the long side of the horizontal piece 22 points to the through holes 21 on both sides, which is used to indicate the direction of the through holes 21. When the injection nozzle 2 is inserted into the tree trunk, the direction of the through hole 21 can be identified through the horizontal piece 22, which facilitates the adjustment of the direction of the through hole 21.

[0033] The material of the above-mentioned dry filling bottle is plastic, stainless steel or glass that is not dissolved by rosin and is resistant to corrosion. Among them, the main components of the plastic that is not dissolved by rosin and is resistant to corrosion include: any one of polytetrafluoroethylene (PTFE), cellulose propionate (CP), phenolic resin (PF), xylene (XR), polycarbonate (PC), furan formaldehyde resin (FF), acrylonitrile-butadiene-styrene copolymer (ABS), polypropylene (PP), and epoxy resin (EP).

[0034] The injection nozzle is a long pointed tip, and tips of different diameters and lengths can be selected according to the diameter of the tree trunk to be injected. The specifications are that the tip length is 5cm-10cm and the diameter is 0.3cm-1cm.

[0035] The above bottle specifications can be selected according to the volume of the dry medicine, and the specifications can be 10mL-50mL.

[0036] This embodiment also provides a method for using the above-mentioned dry filling bottle, including:

[0037] When applying medicine in the forest, the through holes 21 on both sides of the medicine injection nozzle 2 are oriented upward and downward.

[0038] Example 1: Comparison of drilling conditions of different injection nozzles

[0039] A Masson pine forest with a trunk diameter of 16-25cm was selected for trunk injection to explore the effect of whether there are holes on the injection nozzle on the effect of trunk injection. First, when the injection nozzle of the dry injection bottle is not punched, two hole entry methods of the injection nozzle are set: full entry and half entry. Then, 3 holes are punched in a single row on one side of the injection nozzle, and the injection nozzle is inserted into the trunk borehole in a full entry manner, with the hole opening facing up, down, left, and right in four directions. Finally, 3 holes are punched on each side of the injection nozzle, that is, double rows of 6 holes, and the hole opening direction is set in two directions: up and down (vertical) and left and right (horizontal), and then the injection nozzle is inserted into the trunk borehole in a full entry manner. Five repetitions are set for each treatment, as shown in Table 1. A 10mL dry injection bottle was selected for application in the embodiment, and the changes in the liquid level in the bottle were observed at different times after application.

[0040] Table 1 Comparison of drilling conditions of different injection nozzles

[0041]

[0042] Results As shown in Table 2, different treatments were performed on the bottle-inserted self-flowing dry injection bottle. After the application of the drug, the overall effect of the dry injection with a hole in the injection nozzle was better than that without a hole. There was no significant difference in the effect of the dry injection with the injection nozzle half-entered (treatment 1) and fully inserted (treatment 2). Both would cause the rosin to flow back into the dry injection bottle and burst the bottle. When the single-row 3-hole injection nozzle was fully inserted for dry injection, the best effect was when the hole was facing upward (treatment 3), followed by the hole facing downward (treatment 4), and when the hole was facing the side (treatments 5 and 6), the liquid level in the dry injection bottle rose, but the situation was better than the dry injection with the injection nozzle without a hole. When applying medicine using the double-row 6-hole injection nozzle of the present invention, it was found that when the orifice was facing left or right, the resin was still sucked back, and the medicine could not be applied effectively; when the orifice was facing up and down, that is, perpendicular to the horizontal plane, the liquid level in all the injection bottles dropped and exceeded half, and the injection effect was better than that of the single-row 3-hole and no-hole injection bottles. Therefore, the full-entry double-row 6-hole injection bottle provided by the present invention has a good injection effect when applying medicine with the orifice facing up and down, which can prevent the resin from flowing back and causing the bottle body to burst.

[0043] Table 2 Comparison of liquid level changes in the injection bottle with different injection nozzles

[0044]

[0045] Note: Situation after the bottle is filled dry: -The liquid level in the bottle rises and the bottle body bursts; -The liquid level in the bottle rises but the bottle body does not burst; +The liquid level in the bottle drops but does not exceed half; ++The liquid level in the bottle drops and exceeds half.

[0046] Example 2: Comparison of the application of pesticides using self-flowing dry-injection bottles of different specifications

[0047] For the Masson pine forest with different trunk diameters at breast height, the injection nozzles and bottle bodies of the present invention with different specifications can be used for trunk injection and drug application (when applying the drug, the through hole opening is facing up and down, that is, perpendicular to the horizontal plane), 30 trees of each specification are injected and applied, 10 of which are in a group, and three groups are repeated. After application, the changes in the liquid level in the bottle are observed at different times (see Table 3). As can be seen from Table 4, when the trunks of Masson pine trees with different breast diameters are injected and applied with injection bottles of different specifications, there is no situation where the resin is sucked back and bursts the bottle body, and there is no difference between bottles of different volumes. In addition, as the length and diameter of the injection nozzle increase, the injection effect of the injection bottle is better; and the injection effect of the same specification of the injection bottle on the tree with a large breast diameter will be reduced. Therefore, when injecting and applying drugs to Masson pine trees with a larger breast diameter, the injection bottle should select a combination of a large volume of bottle body and a long and larger diameter injection nozzle.
