Description

Technical Field

[0001] This invention relates to a device and method for transplanting garden seedlings, belonging to the field of garden technology. Background Technology

[0002] In the field of seedling transplanting, large seedlings are usually transplanted with a root ball. The size of the root ball depends on the size of the seedling, generally referring to 7 to 10 times the diameter at breast height (DBH) to ground diameter (DBC), ensuring that the main root system is contained within the root ball. The root ball usually needs to be wrapped, using materials such as wire mesh, straw bags, cloth rope, or straw rope. The wrapping should be tight enough to prevent the root ball from falling apart. When planting, the wrapping material should be removed after the seedling is placed in the planting pit to facilitate root growth.

[0003] The seasons for transplanting seedlings are usually spring, summer, and autumn.

[0004] 1. Spring transplanting

[0005] Transplanting is generally carried out in spring before the soil thaws and the seedlings begin to sprout. Immediate irrigation after transplanting ensures the seedlings absorb sufficient water, guaranteeing a higher survival rate.

[0006] 2. Summer transplanting

[0007] Evergreen trees are generally best transplanted during the rainy season in summer, when soil moisture is plentiful and air humidity is high, making it easier to maintain the seedlings' moisture balance and resulting in a high survival rate. When transplanting broad-leaved trees in summer, the crown should be pruned to prevent excessive water evaporation, which can negatively impact seedling growth and survival. Some seedlings also require shading to prevent sun exposure from causing dehydration and affecting their survival rate.

[0008] 3. Autumn transplanting

[0009] Transplanting in autumn should not be too late, otherwise the root system will stop growing, which will be detrimental to the survival of the seedlings. After transplanting, watering is necessary in time, and protective measures such as covering with soil should be taken before winter to prevent the seedlings from being damaged by frost.

[0010] In the field of landscaping, rescue transplantation is sometimes necessary. During spring, summer, and autumn, the soil inevitably contains insect eggs to varying degrees, and the types of eggs differ depending on the local environment. If the geological environment of the original planting site differs significantly from the transplant site, and the transplanting involves transplanting with a soil ball, insect eggs from the soil ball may be carried to the new site. If the eggs are not thoroughly eradicated, the insects may harm the ecology of the transplant site. Current methods for eliminating insect eggs typically involve adding specialized insecticides directly to the soil. However, different types of insect eggs require different insecticides, and the types of insect eggs in the soil are not easily identified. Therefore, the effectiveness of insect egg eradication is limited and it is not environmentally friendly.

[0011] Based on this, the present invention is proposed. Summary of the Invention

[0012] The specific technical solution of the garden seedling transplanting device and transplanting method described in this invention is as follows:

[0013] A method for transplanting garden seedlings includes the following steps:

[0014] Step S1: Based on the extent of the seedling root system and the seedling trunk, dig and trim the soil around the seedling roots into a hemispherical original soil ball. Wrap the original soil ball with kraft paper, and then use straw rope or cloth rope to tie and tighten the outer wall of the original soil ball to obtain the seedling to be transplanted.

[0015] Step S2: Pack the original soil ball and tree trunk of the seedling to be transplanted, then use a crane to lift it onto a truck, and use the truck to transport the seedling to the transplanting site;

[0016] Step S3: Dig a tree pit in the soil layer of the transplanting site, move the original soil ball into the tree pit, straighten the tree trunk, and then backfill the tree pit with soil.

[0017] Step S4: Insert a fence around the tree pit, covering the outside of the sapling trunk. Insert multiple ultrasonic vibrators inside the fence, with the lower end of each vibrator penetrating the original root ball and inserting into the soil layer of the transplanting site. Then, fill the fence with perlite, forming a perlite layer. The upper end of the ultrasonic vibrators is higher than the upper end of the perlite layer, while the upper end of the perlite layer is lower than the upper end of the fence. Above the perlite layer, multiple electric vibrating discs are installed to apply vertical vibration to the perlite layer. Water is poured into the perlite layer inside the fence. When the soil moisture content at a distance of 3-6 cm from the bottom of the fence reaches 17%-19%, watering of the perlite layer inside the fence is stopped. Water is added to the perlite layer inside the fence, and the ultrasonic vibrators and electric vibrating discs are started for combined vibration operation. After 1.5-2 hours of combined vibration operation, let it stand for 3-6 hours. Afterward, remove the electric vibrating discs, fence, perlite layer, and ultrasonic vibrators in sequence, and clean the perlite around the sapling trunk.

[0018] Step S5: Mound soil around the trunk of the sapling and tamp it down; fix the trunk of the sapling with triangular / quadrangular supports, and water, fertilize and maintain it regularly.

[0019] Furthermore, in step S1, the ratio of the diameter of the original soil ball to the diameter of the seedling trunk is greater than or equal to 8.

[0020] Furthermore, in step S4, there are three ultrasonic vibrating rods and three electric vibrating disks. The three ultrasonic vibrating rods are symmetrically arranged with the tree trunk as the center, and the three electric vibrating disks are symmetrically arranged with the tree trunk as the center. The ultrasonic vibrating rods and electric vibrating disks are spaced apart. The difference in ultrasonic frequency between any two of the three ultrasonic vibrating rods is greater than or equal to 13kHz.

[0021] Furthermore, in step S4, the ultrasonic frequency of the first ultrasonic vibrator is 79kHz, the ultrasonic frequency of the second ultrasonic vibrator is 50kHz, and the ultrasonic frequency of the third ultrasonic vibrator is 93kHz; the vibration frequency of the three electric vibrating plates is 20-40Hz, and the amplitude is 1-2mm.

[0022] Furthermore, the kraft paper in step S1 is obtained by spraying a modified chitosan solution onto the surface of kraft base paper and then drying it at 50-55°C; the preparation method of the modified chitosan solution is as follows:

[0023] 10 parts by mass of a 1.5% chitosan solution, 0.3 parts by mass of aluminic acid, and 0.5 parts by mass of ferric chloride were mixed and stirred at 75-80°C for 60-70 minutes to obtain the modified chitosan solution.

[0024] A 1.5% chitosan solution is obtained by adding chitosan to a 2-3% acetic acid solution and stirring in a water bath at 55-60°C until the chitosan is completely dissolved.

[0025] Furthermore, a garden seedling transplanting device includes a crane, a truck, and an ultrasonic insecticidal egg-killing mechanism. The ultrasonic insecticidal egg-killing mechanism includes a fence fitted over the outside of the seedling trunk, with the lower end of the fence inserted into the soil layer of the transplanting site. Multiple ultrasonic vibrating rods are inserted inside the fence, with the lower end of each vibrating rod penetrating the original root ball and then inserted into the soil layer of the transplanting site. The fence is filled with perlite, forming a perlite layer. The upper end of each ultrasonic vibrating rod is higher than the upper end of the perlite layer. The upper end of the perlite layer is lower than the upper end of the fence. Multiple electric vibrating discs are installed above the perlite layer to apply vertical vibration to it. Water is poured into the perlite layer inside the fence, and when the soil moisture content at a distance of 3-6 cm from the bottom of the fence reaches 17%-19%, watering of the perlite layer inside the fence is stopped.

[0026] Furthermore, the fence comprises multiple vertical panels, with aluminum foil fiberglass cloth connecting adjacent vertical panels.

[0027] Furthermore, the edge of the electric vibratory feeder is connected to a restraint rope, which is fixedly connected to the fence.

[0028] Furthermore, the thickness of the perlite layer is 0.5–1 m.

[0029] The beneficial effects of this invention are:

[0030] This invention optimizes the existing seedling transplanting process with soil balls by adding an ultrasonic egg-killing mechanism after transplanting. The superimposed ultrasonic waves of three frequencies can kill insect eggs carried in the original soil ball and those embedded in the bark at the base of the trunk, resulting in a good killing effect. At the same time, the superimposed ultrasonic waves cause almost no damage to the seedling's root system, making it particularly suitable for transplanting seedlings with soil balls and promoting seedling survival. Seedlings transplanted using this method have a survival rate of over 98%. Attached Figure Description

[0038] Example 1

[0039] A method for transplanting garden seedlings includes the following steps:

[0040] Step S1, as follows Figures 1-3 As shown, based on the extent of the seedling root system and the seedling trunk 10, the soil around the seedling roots and the surrounding soil is excavated and trimmed into a hemispherical original soil ball 11. The original soil ball 11 is wrapped with kraft paper, and then the outer wall of the original soil ball 11 is bound and tightened with straw rope to obtain the seedling to be transplanted; wherein, the ratio of the diameter of the original soil ball 11 to the diameter of the seedling trunk 10 is greater than or equal to 8.

[0041] Step S2: Pack the original soil ball 11 and the tree trunk 10 of the seedling to be transplanted, then use a crane to lift them onto a truck, and use the truck to transport the seedling to be transplanted to the transplanting site;

[0042] Step S3: Dig a tree pit at the soil layer 12 of the transplanting site, remove the packaging material on the surface of the original soil ball 11 and the seedling trunk 10, move the original soil ball 11 into the tree pit, straighten the seedling trunk 10, and then backfill the tree pit with soil; wherein, the kraft paper on the original soil ball 11 is still left in the tree pit, so as to keep the soil at a relatively warm water during ultrasonic vibration.

[0043] Step S4: Insert a fence 21 around the tree pit, the fence 21 covering the outside of the sapling trunk 10. Insert three ultrasonic vibrating rods 23 inside the fence 21, the lower end of the ultrasonic vibrating rods 23 penetrating the original root ball 11 and inserting into the soil layer 12 of the transplanting site. Then, fill the fence 21 with perlite, forming a perlite layer 22. The upper end of the ultrasonic vibrating rods 23 is higher than the upper end of the perlite layer 22, and the upper end of the perlite layer 22 is lower than the upper end of the fence 21. Three electric vibrating discs 24 are installed above the perlite layer 22 to apply vertical vibration to the perlite layer 22. Water the perlite layer 22 inside the fence 21. When the soil moisture content 3-6 cm from the bottom of the fence 21 reaches 17%-19%, stop watering the fence. Water is poured into the perlite layer 22 within the enclosure 21; water is added to the perlite layer 22 within the enclosure 21 at a flow rate of 3-5 L / min. The ultrasonic vibrator 23 and the electric vibrating plate 24 are started for combined vibration operation. After 1.5-2 hours of combined vibration operation, the enclosure is left to stand for 3-6 hours. Afterward, the electric vibrating plate 24, enclosure 21, perlite layer 22, and ultrasonic vibrator 23 are removed in sequence, and the perlite around the seedling trunk 10 is cleaned. The three ultrasonic vibrators 23 are symmetrically arranged with the seedling trunk 10 as the center, and the three electric vibrating plates 24 are symmetrically arranged with the seedling trunk 10 as the center. The ultrasonic vibrators 23 and the electric vibrating plates 24 are spaced apart. The difference in ultrasonic frequency between any two of the three ultrasonic vibrators 23 is greater than or equal to 13 kHz. The ultrasonic frequency of the first ultrasonic vibrator is 79kHz, the ultrasonic frequency of the second ultrasonic vibrator is 50kHz, and the ultrasonic frequency of the third ultrasonic vibrator is 93kHz; the vibration frequency of the three electric vibrating plates is 20-40Hz, and the amplitude is 1-2mm.

[0044] Step S5: Mound soil around the trunk 10 of the sapling and tamp it down. Secure the trunk 10 with triangular supports and water, fertilize, and maintain it regularly. Insert cross stakes at the contact points of the support poles, with the stakes extending at least 1 meter into the ground. The triangular supports effectively prevent excessive shaking of the trunk 10, avoiding root breakage, while the cross stakes prevent movement of the original root ball 11, ensuring the transplanted sapling is as stable as possible.

[0045] Example 2

[0046] In Example 1, the kraft paper in step S1 is obtained by spraying a modified chitosan solution onto the surface of kraft base paper and then drying it at 50-55°C; the preparation method of the modified chitosan solution is as follows:

[0047] 10 kg of a 1.5% chitosan solution, 0.3 kg of aluminic acid, and 0.5 kg of ferric chloride were mixed and stirred at 75–80 °C for 60–70 min to obtain the modified chitosan solution.

[0048] A 1.5% chitosan solution is obtained by adding chitosan to a 2-3% acetic acid solution and stirring in a water bath at 55-60°C until the chitosan is completely dissolved.

[0049] In this invention, aluminum and iron ions, under heating, combine to form a cross-linked network on the surface of chitosan, making the solution viscous. After drying, this viscous solution adheres to the kraft paper, forming a waterproof film. The chitosan matrix remains a biodegradable material. Therefore, this kraft paper can degrade in soil within a short time.

[0050] Kraft paper coated with a modified chitosan solution, when used to make paper bags, did not leak after being filled with water for 2 hours. After being ultrasonically cleaned at a frequency of 79 kHz for 1 hour, 1.5 hours, and 2 hours, the kraft paper remained intact for the first 1.5 hours and retained its waterproof function after drying. After 1.5 hours of ultrasonic cleaning, the kraft paper began to break apart, and a large number of paper scraps appeared floating on the water surface, indicating that the kraft paper had begun to decompose. In contrast, existing coated kraft paper did not crack even after 3 hours of ultrasonic cleaning.

[0051] As a control, if aluminic acid or ferric chloride is not added when modifying chitosan, the resulting kraft paper has poor waterproof performance (the paper bag drips a lot of water after being filled with water for 30 minutes).

[0052] If a 1.5% chitosan solution is directly coated onto kraft paper, the resulting kraft paper will have poor water resistance (a large amount of water will drip after the paper bag is filled with water for 30 minutes), and the kraft paper will decompose after 20 minutes of ultrasonication.

[0053] Example 3

[0054] like Figures 1-3As shown, a garden seedling transplanting device includes a crane, a truck, and an ultrasonic insect egg killing mechanism. The ultrasonic insect egg killing mechanism 20 includes a fence 21 fitted over the outside of the seedling trunk 10. The lower end of the fence 21 is inserted into the soil layer 12 of the transplanting site. Multiple ultrasonic vibrating rods 23 are inserted inside the fence 21, with the lower end of each ultrasonic vibrating rod 23 penetrating the original root ball 11 and then inserted into the soil layer 12 of the transplanting site. The fence 21 is filled with perlite, and the perlite inside the fence 21 forms... The perlite layer 22 has its upper end higher than the upper end of the ultrasonic vibrating rod 23; the upper end of the perlite layer 22 is lower than the upper end of the fence 21; multiple electric vibrating discs 24 are installed above the perlite layer 22 to apply vertical vibration to the perlite layer 22; water is poured into the perlite layer 22 inside the fence 21, and when the soil moisture content at a distance of 3-6 cm from the bottom of the fence 21 reaches 17%-19%, the watering of the perlite layer 22 inside the fence 21 is stopped.

[0055] The fence 21 comprises multiple vertical panels, with aluminum foil and fiberglass cloth connecting adjacent panels. A restraining rope 25 is connected to the edge of the electric vibrating plate 24, and the restraining rope 25 is fixedly connected to the fence 21. The function of the restraining rope 25 is to prevent the electric vibrating plate 24 from shifting too far. The perlite layer 22 has a thickness of 0.5–1 m.

[0056] In addition, ultrasonic vibration can also kill some insect eggs on the surface of tree trunks.

[0057] Insect egg eradication effect

[0058] Simulation Group 1: A soil ball with a diameter of 1.5m (equivalent to the original soil ball 11) is constructed. Insect egg holes are drilled into the soil ball, and grub eggs, termite eggs, and mole cricket eggs (all insect eggs were purchased from Suiping Yongsheng Insect Industry Co., Ltd.) are implanted. The insect eggs are all wrapped in cotton bags. Root holes are then drilled, and fine roots are placed into the root holes, which are also wrapped in cotton bags. Soil is backfilled into the insect egg holes and root holes. Finally, an ultrasonic insect egg killing mechanism 20 is constructed by sequentially setting up an electric vibrating plate 24, a fence 21, a perlite layer 22, and an ultrasonic vibrating rod 23. Water the perlite layer 22 inside the fence 21. When the soil moisture content at a depth of 6 cm from the bottom of the fence 21 reaches 17%–19%, stop watering the perlite layer 22 inside the fence 21. Replenish water to the perlite layer 22 inside the fence 21 at a flow rate of 3–5 L / min. Start the ultrasonic vibrator 23 and the electric vibrating plate 24 for combined vibration. After 2 hours of combined vibration, let it stand for 3 hours. Then, remove the electric vibrating plate 24, fence 21, perlite layer 22, and ultrasonic vibrator 23 in sequence. Clean the perlite around the trunk 10 of the seedling. Take out the cotton bags containing insect eggs and the cotton bags containing fine roots, clean them, wipe them dry with absorbent paper, and let them air dry for one day. Use a magnifying glass to observe whether the insect eggs are damaged and whether the fine roots are rotten. Calculate the insect egg damage rate (number of damaged insect eggs / total number of insect eggs) and the fine root rot rate (number of rotten fine roots / total number of fine roots). A higher rate of insect egg breakage indicates a better insect egg eradication effect. A lower rate of fine root rot indicates a smaller impact of ultrasonic vibration on the seedling roots.

[0059] Parameters: The ultrasonic frequency of the first ultrasonic vibrator is 79kHz, the ultrasonic frequency of the second ultrasonic vibrator is 50kHz, and the ultrasonic frequency of the third ultrasonic vibrator is 93kHz; the vibration frequency of the three electric vibrating plates is 20-40Hz, and the amplitude is 1-2mm.

[0060] In simulation group 1, the egg breakage rate was 99.1% and the fine root rot rate was 1.1%.

[0061] Compared with the simulated group 1, the ultrasonic frequency of the three ultrasonic vibrators was 20kHz, and all other parameters were the same. The insect egg breakage rate was 100%, and the fine root rot rate was 88.6%.

[0062] Compared with the simulated group 1, the ultrasonic frequency of the three ultrasonic vibrators in control group 2 was 79kHz, and all other parameters were the same. The insect egg breakage rate was 11.9%, and the fine root rot rate was 59.3%.

[0063] In control group 3, compared with simulated group 1, the ultrasonic frequency of the first ultrasonic vibrator was 50kHz, the ultrasonic frequency of the second ultrasonic vibrator was 50kHz, and the ultrasonic frequency of the third ultrasonic vibrator was 93kHz. All other parameters were the same. The egg breakage rate was 23.2%, and the fine root rot rate was 65.5%.

[0064] In control group 4, compared with simulated group 1, the ultrasonic frequency of the first ultrasonic vibrator was 60kHz, the ultrasonic frequency of the second ultrasonic vibrator was 50kHz, and the ultrasonic frequency of the third ultrasonic vibrator was 93kHz. All other parameters were the same. The egg breakage rate was 18.1%, and the fine root rot rate was 50.7%.

[0065] In control group 5, compared with simulated group 1, the electric vibratory feeder 24 was not started, and all other conditions were the same. The insect egg breakage rate was 95.7%, and the fine root rot rate was 77.2%.

[0066] Compared with simulated group 1, the vibration frequency of the three electric vibratory discs in control group 6 was 60-80Hz, and all other parameters were the same. The insect egg breakage rate was 89.8%, and the fine root rot rate was 8.3%.

[0067] In control group 7, compared with simulated group 1, watering of the perlite layer 22 inside the fence 21 was stopped when the soil moisture content at 6cm from the bottom of the fence 21 reached 10% to 11%; all other conditions were the same, and the insect egg breakage rate was 41.8%.

[0068] In control group 8, compared with simulated group 1, watering of the perlite layer 22 inside the fence 21 was stopped when the soil moisture content at 6cm from the bottom of the fence 21 reached 23% to 25%; all other conditions were the same, with an insect egg breakage rate of 99.5% and a fine root rot rate of 39.6%.

[0069] In the above embodiment, in this invention, by storing water within the perlite layer 22, the ultrasonic vibrations generated by the ultrasonic vibrator 23 can be better transmitted to the soil where the roots of the seedling trunk 10 are located through the water medium. This allows the ultrasonic waves to kill insect eggs inside the soil. Simultaneously, the electric vibrating plate 24 is controlled to apply downward vibration. During this process, the density within the perlite layer 22 will continuously fluctuate. Due to the vertical vibration impact, the size of the gaps between the perlite layers is constantly changing, and therefore the amount of water within the gaps is also dynamically changing, as is the transmitted ultrasonic vibration (sometimes high, sometimes low). If the ultrasonic frequency remains constant, it can easily damage some of the seedling's fine roots, affecting the growth and survival of the transplanted seedling.

[0070] Kraft paper, in its unprocessed state (raw kraft paper), possesses a certain degree of water resistance, but it cannot withstand prolonged immersion in water without becoming wet. To achieve complete waterproofing, the raw kraft paper requires secondary processing, such as surface coating or gluing. However, existing coating and gluing methods are unsuitable for this invention due to their difficulty in degradation. If the kraft paper, wrapped around the original soil ball 11, does not degrade quickly enough, it will affect root survival. Initially, the ultrasonic insecticidal egg-killing mechanism 20 requires a certain amount of water in the perlite and surrounding soil to ensure its effectiveness. However, after the ultrasonic insecticidal egg-killing mechanism 20 is no longer in use, the kraft paper needs to decompose quickly to avoid impacting seedling growth. Existing methods using coating and gluing to produce kraft paper are unsuitable for this purpose.

[0071] The electric vibratory plate 24 was purchased from Dongguan Wennaikong Electronic Technology Co., Ltd., and the ultrasonic vibrating rod 23 and the mega-sound vibrating rod were both purchased from Guanbo Ultrasonic Shenzhen Co., Ltd.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
