Description

Technical Field

[0001] This invention relates to the field of plant cutting technology, and in particular to a method and apparatus for rapid water propagation of *Gnaphalium affine*. Background Technology

[0002] Cutting propagation is widely used in the cultivation of agricultural and forestry plants. Current technology involves treating the wounds on plant branches and inserting them downwards into the substrate for propagation. During this process, because the branches have no roots and lack water, photosynthesis is slow, resulting in slow growth and the possibility of wound infection. Summary of the Invention

[0003] The purpose of this invention is to provide a method and apparatus for rapid water propagation of *Gnaphalium affine* seedlings, in order to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] This invention provides a method for rapid water propagation of *Gnaphalium affine* seedlings, comprising:

[0006] Prepare the medicine according to the preset components and proportions to form the seedling solution;

[0007] Insert the branches of the *Gnaphalium affine* upside down and soak them in the seedling solution.

[0008] The seedling solution is aerated by mixing air and water according to the first preset time period;

[0009] Supplemental lighting was applied to the *Dioscorea opposita* branches soaked in the seedling solution during the second preset time period.

[0010] Add auxin to the seedling solution according to the third preset time period and then culture in natural light mode;

[0011] Once the roots of the *Gnaphalium affine* branches have grown to their first length, the branches that were soaked in the seedling solution are removed and then cultured by atomized spraying.

[0012] After gradually reducing the water content according to the fourth preset time period to allow the soil to adapt to the natural soil environment, transplant the seedlings.

[0013] The beneficial effects of this invention are:

[0014] This invention involves inserting *Ligustrum lucidum* branches upside down into a solution containing an air-water mixing pump for root-promoting seedling cultivation, effectively avoiding infection caused by the branch wounds coming into contact with water. This method is not affected by water shortages and does not require leaf removal. Utilizing the plant's phototropic characteristics, the branches grow upwards towards the light, emerging above the water surface before root-promoting treatment. Due to its large rooting area and the use of the branch stem as a substitute for the main root, the seedlings grow vigorously and exhibit strong resistance to adverse conditions.

[0017] As a further improvement to the above technical solution, the step of partially immersing the *Gnaphalium affine* branches upside down in the seedling solution further includes:

[0018] The branches of the ground ivy are inclined at a 45-degree angle to the plane of the seedling solution.

[0019] As a further improvement to the above technical solution, the step of partially immersing the *Gnaphalium affine* branches upside down in the seedling solution further includes:

[0020] The top part of the *Gnaphalium affine* branch, which is more than three-quarters the length of the branch, is immersed upside down in the seedling solution, with the wound on the branch hanging above the surface of the solution.

[0021] As a further improvement to the above technical solution, the step of providing supplemental lighting to the *Ligustrum lucidum* branches soaked in the seedling solution according to the second preset time period further includes:

[0022] The branches of the *Gnaphalium affine* were placed in a sealed container and placed under a light source for 24 hours for supplemental lighting.

[0023] As a further improvement to the above technical solution, the step of supplementing the light on the branches of the *Ligustrum lucidum* soaked in the seedling solution according to the second preset time period further includes: the container is made of transparent material.

[0024] As a further improvement to the above technical solution, the step of adding auxin to the seedling solution and culturing under natural light mode according to the third preset time period further includes: the added auxin is indolebutyric acid, and 150 to 300 mg of indolebutyric acid is added to each liter of seedling solution.

[0025] As a further improvement to the above technical solution, in the step of taking out the part of the *Gnaphalium affine* branch that has been soaked in the seedling solution and then transferring it to atomized spray cultivation after the root system of the *Gnaphalium affine* branch has grown to a first length, the first length is 3 cm.

Melastoma dodecandrum has the effects of clearing heat and detoxifying, promoting blood circulation and stopping bleeding. It is commonly used for high fever, lung abscess, pharyngeal swelling, toothache, red and white dysentery, jaundice, edema, dysmenorrhea, metrorrhagia and metrostaxis, leukorrhea, postpartum abdominal pain, scrofula, carbuncle swelling, furuncle and carbuncle, hemorrhoids, snake bites. Due to its bright color and growth in a carpet-like shape, it also has applications in gardening.

[0041] Refer to Figure 1 , the present invention provides a method for rapid water cutting of Melastoma dodecandrum seedlings, and the following embodiments are made:

[0042] A method for rapid water cutting of Melastoma dodecandrum seedlings, trimming the Melastoma dodecandrum branches to a unified length, soaking the top part in the medicinal liquid for fixation, using an air-water mixing pump to perform 24-hour uninterrupted air-water mixing aeration on the medicinal liquid, placing a light above the medicinal liquid to supplement light to the branches, and increasing the submerged part of the branches as much as possible on the premise that the medicinal liquid does not contact the branch wounds. Specifically, it includes the following steps:

[0043] Step S100: Prepare the medicine according to the preset components and ratios to form a seedling-raising medicinal liquid;

[0044] Specifically, the preset components and ratios for preparing the seedling-raising medicinal liquid are a 150 - 200 ppm concentration of pentanediol solution, 1 - 1.5 g / L of urea, 0.5 - 0.8 g / L of potassium dihydrogen phosphate, 1 - 2 g / L of salicylic acid, 0.1 - 0.5 g / L of alcohol, 0.3 - 0.6 g / L of acetic acid, and 0.2 - 0.4 g / L of plant ash. In actual operation, add 1 - 1.5 g / L of urea, 0.5 - 0.8 g / L of potassium dihydrogen phosphate, 1 - 2 g / L of salicylic acid, 0.1 - 0.5 g / L of alcohol, 0.3 - 0.6 g / L of acetic acid, and 0.2 - 0.4 g / L of plant ash to a 150 - 200 ppm concentration of pentanediol solution to form the seedling-raising medicinal liquid.

[0045] Step S200: Invert and soak part of the Melastoma dodecandrum branches in the seedling-raising medicinal liquid;

[0046] More than three-quarters of the top part of the branch is inverted and immersed in the medicinal liquid, and the branch wound is suspended above the liquid level of the seedling-raising medicinal liquid. Preferably, it is inclined at a 45-degree angle to the horizontal plane of the seedling-raising medicinal liquid to increase the light-receiving area of the Melastoma dodecandrum branches.

[0047] Step S300: Perform air-water mixing aeration on the seedling-raising medicinal liquid according to the first preset time period. The air-water mixing pump in the seedling-raising medicinal liquid is turned on for 24 hours;

[0048] Step S400: Provide supplemental lighting to the *Ligustrum lucidum* branches soaked in the seedling solution according to the second preset time period;

[0049] The *Gnaphalium affine* branches were placed in a sealed container and kept under a light source for 24 hours for supplemental cultivation. Therefore, the container was preferably made of a transparent material, i.e., a transparent and light-transmitting material.

[0050] Step S500: Add auxin to the seedling solution according to the third preset time period and switch to natural light mode for cultivation; the third preset time period can be 10 to 15 days, and the added auxin is indolebutyric acid. Specifically, after 10 to 15 days, when the branches grow out of the water surface under light, add 150 to 300 mg of indolebutyric acid per liter of solution, and switch the light to 12 hours of cultivation or rely on natural light for cultivation.

[0051] Step S600: After the roots of the *Euonymus fortunei* branches have grown to a first length, the portion of the *Euonymus fortunei* branches soaked in the seedling solution is removed and transferred to atomized spray culture. The first length is 3 cm. That is, after the roots of the *Euonymus fortunei* branches have grown to a length of 3 cm, they are removed and transferred to a loose and breathable substrate for burial in the water propagation stage, where the underwater portion is atomized and sprayed for 24 hours.

[0052] Step S700: Gradually reduce watering according to the fourth preset time period to allow the seedlings to adapt to the natural soil environment before transplanting. The fourth preset time period is 5 days. That is, after 5 days, transfer the seedlings to a greenhouse for hardening-off treatment, gradually reduce the water supply to allow them to adapt to the natural soil environment, and then transplant them.

[0053] This invention involves inserting *Ligustrum lucidum* branches upside down into a solution containing an air-water mixing pump for root-promoting seedling cultivation, effectively avoiding infection caused by the branch wounds coming into contact with water. This method is not affected by water shortages and does not require leaf removal. Utilizing the plant's phototropic characteristics, the branches grow upwards towards the light, emerging above the water surface before root-promoting treatment. Due to its large rooting area and the use of the branch stem as a substitute for the main root, the seedlings grow vigorously and exhibit strong resistance to adverse conditions.

[0054] More specifically, this method includes two main parts: preparation of the drug solution and specific operations.

[0055] Preparation of seedling solution: Add 1 to 1.5g of urea, 0.5 to 0.8g of potassium dihydrogen phosphate, 1 to 2g of salicylic acid, 0.1 to 0.5g of alcohol, 0.3 to 0.6g of acetic acid, and 0.2 to 0.4g of wood ash to a pentylene glycol solution with a concentration of 150 to 200 ppm per liter.

[0056] Procedure: Immerse the top three-quarters or more of the branch tip of the *Gnaphalium affine* upside down in the seedling treatment solution, with the wound of the branch hanging above the water surface of the solution. Preferably, it should be tilted at a 45-degree angle to the horizontal plane to increase the light-receiving area of ​​the branch. Add an air-water mixing pump to the water and run it for 24 hours. Then, seal the container and place it under a light for 24 hours of light cultivation. The container is preferably made of a transparent and light-transmitting material.

[0057] After 10 to 15 days, once the branches of the *Gnaphalium affine* emerge from the water surface under light, add 150-300 mg of indolebutyric acid per liter of the solution. Reduce the artificial light exposure to 12 hours per day or rely on natural light for cultivation. Once the root system reaches 3 cm in length, remove the cuttings and place them in a loose, well-draining substrate. During the water propagation stage, mist the underwater portion for 24 hours. After 5 days, transfer them to a greenhouse for hardening-off treatment, gradually reducing the water supply to allow them to adapt to the natural soil environment before transplanting.

[0058] Reference Figure 2 The present invention also provides an apparatus for rapid water propagation of *Gnaphalium affine* seedlings, comprising a seedling trough 100, multiple branch fixing clips 200, a lamp tube 300, and an aeration pump 400. The multiple branch fixing clips 200 are evenly distributed above the seedling trough 100. Specifically, each branch fixing clip 200 is elongated, with both ends overlapping the side walls of the seedling trough 100 to fix the branches. Each branch fixing clip 200 includes a first clamping strip and a second clamping strip, with the first clamping strip spaced apart along its length. The device is equipped with a first clamping slot and a second clamping strip with second clamping slots spaced apart along its length. The first and second clamping slots engage with each other. The clamping surfaces between the first and second clamping strips are provided with an elastic layer, which allows it to clamp branches of different specifications without damaging them. Multiple first and second clamping slots form multiple clamping and fixing positions, which can more firmly clamp multiple branches of the ground ivy and reduce the chance of branches falling off during clamping.

[0059] In some other embodiments, the branch fixing clip 200 includes a first clamping strip and a second clamping strip. One end of the first clamping strip and the second clamping strip are hinged to each other, and the other end is fixed with a snap fastener. The branch is fixed by the clamping force of the first clamping strip and the second clamping strip coming together.

[0060] The lamp tube 300 is located above the seedling trough 100 and the branch fixing clip 200 for supplemental lighting; the aeration pump 400 is located at the bottom of the seedling trough 100 and is used to aerate the seedling medicine solution by mixing air and water.
