Description

Technical Field

[0001] This invention belongs to the field of agricultural planting technology, specifically relating to a rapid and high-yield cultivation method for *Caulis Amaranthus rubra*. Background Technology

[0002] *Erythropalum scandens* Bl., commonly known as Red Cang Teng, is a perennial evergreen woody vine belonging to the genus *Erythropalum* in the family Olacaceae. It is mainly distributed in Yunnan, Guizhou, Guangxi, and Guangdong provinces; commonly found in low mountains and hilly areas, along streams, in valleys, and in forest edges or thickets of dense or sparse forests. It is a natural, pollution-free crop with both medicinal and edible uses, and is traditionally harvested for consumption in southern Yunnan, Guangxi, Guangdong, and Hainan. Due to its heat-clearing, diuretic, and uric acid-lowering effects, there is a large market demand, leading to a continuous expansion of its cultivation area. However, because the artificial cultivation environment differs significantly from its original habitat, the current yield of artificially cultivated Red Cang Teng is not high.

[0003] Currently, research on *Cephalotaxus fortunei* mainly focuses on the extraction of medicinal components, seedling cultivation methods, and product development. There are no reports on research into rapid orchard establishment and high-yield cultivation. For example, patents CN 218550790 U and CN 214102554 U only report on greenhouses and climbing frames used for shading *Cephalotaxus fortunei*, without addressing high-yield cultivation. Patent CN107567918A discloses artificial cultivation methods for *Cephalotaxus fortunei*, but only describes conventional cultivation methods regarding seedling raising, selection, transplanting, soil, light, water, and fertilizer. This does not effectively solve the cultivation problems of *Cephalotaxus fortunei*: 1. Conventional planting usually uses small seedlings, which produce seedlings slowly, taking three years to reach full production, resulting in high initial time and land costs; 2. Conventional cultivation methods involve vigorous reproductive growth of *Cephalotaxus fortunei*, with a long flowering and fruiting period, consuming a lot of nutrients, inhibiting vegetative growth, suppressing bud germination, and resulting in low bud yield. Therefore, it is necessary to study the cultivation techniques of *Cephalotaxus fortunei* to achieve rapid and high yields. Summary of the Invention

[0004] To address the above problems, this invention provides a rapid and high-yield cultivation method for *Cephalotaxus fortunei*. Through seedling bagging, large seedling cultivation, large seedling transplanting, post-transplanting management, and high-yield period management, rapid and high-yield production of *Cephalotaxus fortunei* can be achieved, and the yield of tender shoots can be increased.

[0005] This invention is achieved through the following technical solution:

[0006] A rapid and high-yield cultivation method for *Cymbidium goeringii* includes the following steps:

[0007] (1) Packing seedlings: Select healthy and disease-free cuttings of *Ilex chinensis*. Cut off the thick roots of the seedlings that grow vertically, and leave the thin roots untreated. Keep 8-10 cm of vertical roots. Prepare a solution of rooting agent, potassium humate, and fungicide. Soak the cut ends of the roots for 2-3 minutes. Transplant the seedlings into seedling bags, fill the seedling bags with the cultivation substrate, and water thoroughly to settle the roots. This will give you bagged seedlings.

[0008] (2) Large seedling cultivation: The bagged seedlings in step (1) are dwarfed and sturdy. During the cultivation process, a shade shed is built for shading. After the bagged seedlings have recovered for 5 to 7 days, compound fertilizer is applied every 30 to 40 days for 2 to 3 times. Foliar treatment agent is sprayed every 50 to 60 days for 1 to 2 times. Dwarfing pruning is carried out in a timely manner. After 2 years of cultivation, bagged large seedlings of Red Vine are obtained.

[0009] (3) Transplanting large seedlings: Remove the outer bag from the bagged large seedlings in step (2), and then transplant the large seedlings to the field. Before transplanting, set up a shade shed for shading. Do not break the substrate of the large seedlings or damage the root system of the large seedlings during the transplanting process. Planting specifications adopt the wide and narrow row dense planting mode. After watering the roots thoroughly, prepare a solution of rooting agent, mineral potassium humate and fungicide, and then irrigate the roots of the plants. Apply 0.3 to 0.5 L per plant.

[0010] (4) Post-transplanting management: After transplanting large seedlings, manage them according to daily fertilization, pay attention to loosening the topsoil and ensuring ventilation and light penetration, remove excess tender buds in a timely manner, cultivate strong branches and a high-yielding plant type, and a high-yielding plant type can be obtained in the second year.

[0011] (5) Management during the high-yield period: After the plant enters the high-yield period, prune the shaded branches, crossing branches, weak branches and dead branches in a timely manner, and remove the leaves so that each branch of the plant retains 1 / 3 to 1 / 2 of the mature and healthy leaves evenly. Apply water-soluble fertilizer every 10 to 15 days. When the tender shoots grow to 10 to 15 cm, they can be harvested.

[0012] Further, in step (1), the culture substrate comprises the following components in parts by weight: 1-2 parts coconut coir, 2-3 parts perlite, 2-3 parts humus, 5-7 parts peat moss, and 0.5-1 parts well-rotted farmyard manure.

[0013] Furthermore, in steps (1) and (3), 3-5 parts of rooting agent, 6-8 parts of mineral-derived potassium humate, 0.5-1 parts of fungicide and 800-1200 parts of water are prepared into a solution.

[0014] Further, in steps (1) and (3), the rooting agent is composed of naphthaleneacetic acid, 6-benzylaminopurine and alginic acid in a mass ratio of 4-5:1-2:1; the fungicide is potassium permanganate, carbendazim, root rot fungicide or mancozeb.

[0015] Further, in step (2), the foliar treatment agent contains 0.6-0.7% paclobutrazol and 0.5-1% calcium.

[0016] Further, in step (2), the dwarfing pruning specifically involves: topping the plant when the main stem grows to 20-25cm, and pruning the lateral branches at the same time to control the plant's growth height and promote branching growth, so that the branches are evenly distributed, which is conducive to ventilation and light penetration and plant growth.

[0017] Furthermore, in step (2), the compound fertilizer is a nitrogen-phosphorus-potassium compound fertilizer with a content ratio of N:P:K = 15:15:15, and each plant is fertilized with 15-25g each time.

[0018] Furthermore, in steps (2) and (3), the shading rate of the shade shed is 65-75%.

[0019] Further, in step (3), the wide and narrow row dense planting pattern is as follows: the ridge surface is 1.5 to 1.6 m wide, the furrow width is 0.4 to 0.5 m, the single ridge is planted with double rows, the plant spacing is 0.5 to 0.6 m, the wide row spacing is 1.5 to 1.6 m, the narrow row spacing is 0.4 to 0.5 m, and 1300 to 1350 plants are planted per mu.

[0020] Further, in step (5), the water-soluble fertilizer includes 80-100 g / L of amino acids, 180-220 g / L of nitrogen fertilizer, 50-80 g / L of phosphorus fertilizer, 200-230 g / L of potassium fertilizer and 25-30 g / L of micronutrient fertilizer; the water-soluble fertilizer is diluted 800-1000 times before use, and 0.3-0.5 L is applied to each plant.

[0021] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0022] 1. The rapid and high-yield cultivation method for *Aglaonema edulis* of this invention, through seedling bagging, large seedling cultivation, large seedling transplanting, post-transplanting management, and high-yield period management, enables rapid orchard establishment and high yield of *Aglaonema edulis*, increasing the yield of tender shoots. The bagged *Aglaonema edulis* seedlings cultivated by the method of this invention are robust, grow rapidly after field transplanting, and form forests quickly, shortening the orchard establishment time, reducing early planting costs, and allowing for trial harvesting of tender shoots in the same year of field transplanting by cultivating robust branches.

[0023] 2. This invention involves dwarfing and cultivating seedlings in bags until they become robust, then transplanting them to the field. The seedlings reach full production in the second year after transplanting. Compared to conventional methods, this shortens the field planting time by two years, saving planting time and costs. Larger seedlings are easier to manage, reducing the need for replanting. After reaching full production, leaf removal ensures that 1 / 3 to 1 / 2 of the mature, healthy leaves are evenly retained on each branch, effectively reducing flowering and labor costs associated with manual flower removal. This, in turn, promotes the growth of new buds and increases bud yield. In this invention, *Cephalotaxus fortunei* reaches full production in the second year, saving two years of land management costs compared to traditional seedling planting (which reaches full production in the fourth year). Furthermore, the yield in the second year is more than nine times that of conventional methods, resulting in high economic benefits.

[0024] 3. Before bagging the seedlings, this invention prunes the vertical, thick roots of the seedlings, retaining the horizontally growing roots, and applies a root-promoting treatment to the cut ends to encourage the seedlings to produce more new roots. Compared to traditional methods of bagging seedlings, this invention can increase the number of roots in *Ilex crenata* seedlings, control the growth length of the vertical roots, increase root density, and effectively reduce the problem of excessively long vertical roots penetrating the bottom of the seedling bag during the cultivation of large bagged seedlings.

[0025] 4. This invention uses a solution prepared from a rooting agent, mineral-derived potassium humate, and a fungicide for root promotion in seedlings and root irrigation in mature seedlings. The naphthaleneacetic acid in the rooting agent promotes the formation of adventitious roots and roots; 6-benzylaminopurine effectively promotes plant cell division and growth; alginic acid contains various nutrients necessary for plant growth, such as nitrogen, phosphorus, potassium, and magnesium, providing rich nutrition and effectively promoting plant growth and enhancing plant vitality. Mineral-derived potassium humate improves plant growth and development, enhances resistance to environmental stress, and effectively improves soil structure. The fungicide inhibits fungi, bacteria, viruses, and other microorganisms, effectively preventing root diseases. Root promotion in seedlings and root irrigation in mature seedlings promotes root growth, increases seedling growth rate, accelerates forest formation, and promotes rapid and abundant yield of *Cephalotaxus fortunei*.

[0026] 5. The cultivation substrate used in this invention is composed of coconut coir, perlite, humus, peat moss, and well-rotted farmyard manure. Coconut coir possesses excellent air and water permeability as well as water and fertilizer retention; perlite has good air and water permeability and inorganic properties; peat moss is lightweight, highly absorbent, and rich in organic matter and humus. This cultivation substrate is loose, well-drained, and nutrient-rich, suitable for the rapid growth of *Ilex chinensis* seedlings and promotes the rapid acquisition of larger seedlings.

[0027] 6. In the cultivation of large seedlings, this invention involves dwarfing and strengthening the seedlings. Specifically, this is achieved by spraying the seedlings with a foliar treatment agent containing paclobutrazol and calcium, followed by dwarfing pruning. Paclobutrazol slows plant growth, inhibits stem elongation, and promotes thicker stems and roots. Calcium is an important nutrient element for cell walls; spraying calcium fertilizer promotes thicker leaves, root growth, and enhances the plant's disease resistance and stress tolerance. By cultivating robust seedlings with strong root systems, the survival rate of large seedlings after transplanting can be effectively improved, and the recovery period can be shortened. Furthermore, the dwarfed stems and thicker branches provide sufficient nutrients for plant growth, allowing the large seedlings to recover and grow rapidly after transplanting to the field.

[0028] 7. This invention utilizes shade structures during seedling cultivation and transplanting to prevent sunscald on the leaves of *Ilex chinensis* during its growth, avoid rapid maturation of tender shoots, increase the length of harvestable shoots, improve shoot yield, and enhance shoot quality. Furthermore, when transplanting large seedlings, a wide-narrow row planting pattern is employed. This pattern ensures good ventilation and light exposure between plants, enhancing plant growth, reducing disease incidence, and decreasing pesticide use. The dense planting also increases the planting density per unit area, thereby increasing shoot yield. Attached Figure Description

[0033] The present invention will be further described in detail below through embodiments. These embodiments are only used to illustrate the present invention and do not limit the scope of protection of the present invention.

[0034] Example 1

[0035] A rapid and high-yield cultivation method for *Cymbidium goeringii* includes the following steps:

[0036] (1) Packaging of seedlings: Select healthy and disease-free cuttings of *Ilex chinensis*. Cut off the thick roots of the seedlings that grow vertically, and leave the thin roots untreated. Keep 10cm of vertical roots. Prepare a solution by mixing 4 parts of rooting agent (composed of naphthaleneacetic acid, 6-benzylaminopurine and alginic acid in a mass ratio of 4:2:1), 6 parts of mineral potassium humate, 1 part of carbendazim and 1200 parts of water. Soak the cut ends of the roots for 3 minutes. Transplant the seedlings into seedling bags of 7L or more. Fill the seedling bags with the cultivation substrate, which includes 2 parts of coconut coir, 3 parts of perlite, 2 parts of humus, 6 parts of peat moss and 1 part of well-rotted farmyard manure. After watering thoroughly, the seedlings are packaged in bags.

[0037] (2) Large seedling cultivation: The bagged seedlings from step (1) are dwarfed and sturdy. During the cultivation process, a shade shed with a shading rate of 65% is built for shading. After the bagged seedlings have recovered for 5 days, nitrogen, phosphorus and potassium compound fertilizer (N:P:K=15:15:15) is applied every 30 days for 3 times, with 15g of fertilizer applied to each plant each time. Foliar treatment agent (paclobutrazol content 0.6%, calcium content 0.8%) is sprayed every 20 days for 2 times. Dwarfing pruning is also carried out. Specifically, when the main stem of the plant grows to 20cm, the top is pinched off. At the same time, the side branches are pruned to control the height of the plant and promote branching growth, so that the branches are evenly distributed, which is conducive to ventilation and light penetration and plant growth. After 2 years of cultivation, bagged large seedlings of *Cephalotaxus fortunei* are obtained. The cultivation diagram of bagged large seedlings is shown in the figure. Figure 1 As shown;

[0038] (3) Transplanting of large seedlings: Transplanting of large seedlings is carried out from the winter solstice to the beginning of summer of the following year. Remove the outer bag from the bagged large seedlings in step (2) and then transplant the large seedlings to the field. Before transplanting, a shade shed with a shading rate of 65% is built for shading. During the transplanting process, the substrate of the large seedlings is not broken and the root system of the large seedlings is not damaged. The planting specifications adopt the wide and narrow row dense planting mode, specifically: ridge surface 1.5m, furrow width 0.5m, single ridge double row planting, plant spacing 0.5m, wide row spacing 1.5m, narrow row spacing 0.5m, planting 1334 plants / mu. After watering the roots thoroughly, drench the plants with a solution of 4 parts of rooting agent (composed of naphthaleneacetic acid, 6-benzylaminopurine and alginic acid in a mass ratio of 4:2:1), 6 parts of mineral potassium humate, 1 part of root rot fungicide and 800 parts of water, applying 0.5L to each plant. The growth diagram of the bagged large seedlings two months after transplanting to the field is shown in the figure. Figure 2 As shown;

[0039] (4) Post-transplanting management: After the large seedlings have recovered for 7 days after transplanting, they should be managed according to the daily fertilization. Pay attention to loosening the topsoil and ensuring ventilation and light penetration. Remove excess tender buds in a timely manner to cultivate strong branches and a high-yielding plant shape. A high-yielding plant shape can be obtained in the second year.

[0040] (5) Management during the peak production period: After the plant enters the peak production period, prune shaded branches, crossing branches, weak branches, and dead branches in a timely manner, and remove leaves so that each branch of the plant retains 1 / 2 mature and healthy leaves evenly. Apply water-soluble fertilizer every 15 days. This water-soluble fertilizer contains 80g / L of amino acids, 200g / L of nitrogen fertilizer, 50g / L of phosphorus fertilizer, 200g / L of potassium fertilizer, and 25g / L of micronutrient fertilizer. Dilute the water-soluble fertilizer 800 times before use, and apply 0.5L to each plant. Harvest when the tender shoots grow to 12cm. See the picture of the tender shoot growth of the Red Vine for example. Figure 3 As shown, after pruning and leaf removal, the plant's new shoots grow vigorously, but it produces fewer flowers.

[0041] Example 2

[0042] A rapid and high-yield cultivation method for *Cymbidium goeringii* includes the following steps:

[0043] (1) Packaging of seedlings: Select healthy and disease-free cuttings of *Ilex chinensis*. Cut off the thick roots of the seedlings that grow vertically, and leave the thin roots untreated. Keep 8cm of vertical roots. Prepare a solution by mixing 3 parts of rooting agent (composed of naphthaleneacetic acid, 6-benzylaminopurine and alginic acid in a mass ratio of 5:2:1), 8 parts of mineral potassium humate, 0.5 parts of root rot control agent and 1000 parts of water. Soak the cut ends of the roots for 3 minutes. Then transplant the seedlings into seedling bags of 7L or more. Fill the seedling bags with the cultivation substrate, which includes 1 part coconut coir, 2 parts perlite, 3 parts humus, 7 parts peat moss and 0.5 parts well-rotted farmyard manure. After watering thoroughly, the seedlings are packaged in bags.

[0044] (2) Large seedling cultivation: The bagged seedlings in step (1) are dwarfed and sturdy. During the cultivation process, a shade shed with a shading rate of 70% is built for shading. After the bagged seedlings have recovered for 7 days, nitrogen, phosphorus and potassium compound fertilizer (N:P:K=15:15:15) is applied once every 40 days, and fertilization is carried out twice. Each plant is fertilized with 20g each time. Foliar treatment agent (paclobutrazol content 0.6% and calcium content 0.8%) is sprayed once every 20 days, and dwarfing pruning is carried out. Specifically, when the main stem of the plant grows to 25cm, the top is pinched off. At the same time, the side branches are pruned to control the growth height of the plant and promote the growth of branches, so that the branches are evenly distributed, which is conducive to ventilation and light penetration and plant growth. After 2 years of cultivation, bagged large seedlings of Red Vine are obtained.

[0045] (3) Transplanting of large seedlings: Transplanting of large seedlings is carried out from the winter solstice to the beginning of summer of the following year. Remove the outer bag from the bagged large seedlings in step (2) and then transplant the large seedlings to the field. Before transplanting, a shade shed with a shading rate of 70% is built for shading. During the transplanting process, the substrate of the large seedlings is not broken and the root system of the large seedlings is not damaged. The planting specifications adopt the wide and narrow row dense planting mode, specifically: ridge surface 1.5m, furrow width 0.5m, single ridge double row planting, plant spacing 0.6m, wide row spacing 1.6m, narrow row spacing 0.5m, planting 1310 plants / mu. After watering the roots thoroughly, prepare a solution of 5 parts of rooting agent (composed of naphthaleneacetic acid, 6-benzylaminopurine and alginic acid in a mass ratio of 4:2:1), 8 parts of mineral potassium humate, 0.5 parts of mancozeb and 900 parts of water and apply it to the roots of the plants. Apply 0.5L to each plant.

[0046] (4) Post-transplanting management: After the large seedlings have recovered for 5 days after transplanting, manage them according to the daily fertilization, pay attention to loosening the topsoil and ensuring ventilation and light penetration, remove excess tender buds in a timely manner, cultivate strong branches and a high-yielding plant type, and a high-yielding plant type can be obtained in the second year.

[0047] (5) Management during the high-yield period: After the plant enters the high-yield period, prune the shaded branches, crossing branches, weak branches and dead branches in a timely manner, and remove the leaves so that each branch of the plant retains 1 / 3 of the mature and healthy leaves evenly. Apply water-soluble fertilizer every 10 days. The water-soluble fertilizer includes 100g / L of amino acids, 180g / L of nitrogen fertilizer, 60g / L of phosphorus fertilizer, 230g / L of potassium fertilizer and 30g / L of micronutrient fertilizer. Dilute the water-soluble fertilizer 900 times before use. Apply 0.5L to each plant. When the tender shoots grow to 10cm, they can be harvested.

[0048] Example 3

[0049] A rapid and high-yield cultivation method for *Cymbidium goeringii* includes the following steps:

[0050] (1) Packaging of seedlings: Select healthy and disease-free cuttings of *Ilex chinensis*. Cut off the thick roots of the seedlings that grow vertically, and leave the thin roots untreated. Keep 10cm of vertical roots. Prepare a solution by mixing 3 parts of rooting agent (composed of naphthaleneacetic acid, 6-benzylaminopurine and alginic acid in a mass ratio of 4:2:1), 8 parts of potassium humate, 1 part of potassium permanganate and 1000 parts of water. Soak the cut ends of the roots for 2 minutes. Then transplant the seedlings into seedling bags of 7L or more. Fill the seedling bags with the cultivation substrate, which includes 1 part coconut coir, 2 parts perlite, 3 parts humus, 5 parts peat moss and 0.5 parts well-rotted farmyard manure. After watering thoroughly, the seedlings are bagged.

[0051] (2) Cultivation of large seedlings: The bagged seedlings in step (1) are dwarfed and sturdy. During the cultivation process, a shade shed with a shading rate of 65% is built for shading. After the bagged seedlings have recovered for 7 days, nitrogen, phosphorus and potassium compound fertilizer (N:P:K=15:15:15) is applied once every 40 days for 3 times. Each plant is fertilized with 15g each time. Foliar treatment agent (paclobutrazol content 0.6% and calcium content 0.8%) is sprayed once every 20 days. Dwarfing pruning is also carried out. Specifically, when the main stem of the plant grows to 20cm, the top is pinched off. At the same time, the side branches are pruned to control the plant growth height and promote branching growth, so that the branches are evenly distributed, which is conducive to ventilation and light penetration and plant growth. After 2 years of cultivation, bagged large seedlings of Red Vine are obtained.

[0052] (3) Transplanting of large seedlings: Transplanting of large seedlings is carried out from the winter solstice to the beginning of summer of the following year. Remove the outer bag from the bagged large seedlings in step (2) and then transplant the large seedlings to the field. Before transplanting, a shade shed is built for shading. During the transplanting process, the substrate of the large seedlings is not broken and the root system of the large seedlings is not damaged. The planting specifications adopt the wide and narrow row dense planting mode, specifically: 1.5m ridge surface, 0.4m furrow width, single ridge double row planting, plant spacing 0.5m, wide row spacing 1.5m, narrow row spacing 0.4m, planting 1327 plants / mu. After watering the roots thoroughly, 5 parts of rooting agent (composed of naphthaleneacetic acid, 6-benzylaminopurine and alginic acid in a mass ratio of 4:1:1), 7 parts of mineral potassium humate, 1 part of carbendazim and 900 parts of water are prepared to irrigate the roots of the plants, and 0.4L is applied to each plant.

[0053] (4) Post-transplanting management: After the large seedlings have recovered for 7 days after transplanting, they should be managed according to the daily fertilization. Pay attention to loosening the topsoil and ensuring ventilation and light penetration. Remove excess tender buds in a timely manner to cultivate strong branches and a high-yielding plant shape. A high-yielding plant shape can be obtained in the second year.

[0054] (5) Management during the high-yield period: After the plant enters the high-yield period, prune the shaded branches, crossing branches, weak branches and dead branches in a timely manner, and remove the leaves so that each branch of the plant retains 1 / 2 mature and healthy leaves evenly. Apply water-soluble fertilizer every 10 days. The water-soluble fertilizer includes 10g / L of amino acids, 220g / L of nitrogen fertilizer, 60g / L of phosphorus fertilizer, 230g / L of potassium fertilizer and 30g / L of micronutrient fertilizer. Dilute the water-soluble fertilizer 100 times before use. Apply 0.5L to each plant. When the tender shoots grow to 15cm, they can be harvested.

[0055] Comparative Example 1

[0056] Comparative Example 1 used 1-year-old cuttings for planting and was cultivated and managed according to the conventional single-row planting method (row spacing 1.5m, plant spacing 0.5m).

[0057] Comparative Example 2

[0058] Comparative Example 2 used 2-year-old cuttings for direct field planting, and the rest of the cultivation process and conditions were the same as those in Example 1.

[0059] Comparative Example 3

[0060] The difference between Comparative Example 3 and Example 1 is that in step (5) of Comparative Example 3, leaf removal is not performed during the high-yield management process, and normal growth is maintained. The rest of the cultivation process and conditions are the same as those in Example 1.

[0061] The number of years that the *Ilex chinensis* seedlings reached full production from the time of planting and the corresponding yield of new shoots in Examples 1-3 and Comparative Examples 1-3 were statistically analyzed. The results are shown in Table 1 below.

[0062] Table 1 Yield of young shoots from *Ivy chinensis*

[0063]

[0064] In Table 1, the present invention, in the year of transplanting large *Aglaonema 'Red' seedlings, yielded over 426 kg / mu of tender shoots, allowing for harvesting of tender shoots in the same year. High yields were achieved in the second year, exceeding 1162 kg / mu, and in the third and fourth years, exceeding 1330 kg / mu, demonstrating high tender shoot yield. In contrast, Comparative Example 1, using cuttings and conventional cultivation and management methods, produced no yield in the first year, only slight yields in the second and third years, and high yields only achieved in the fourth year, exhibiting a slow rate of increase and low tender shoot yield. Compared to Comparative Example 1, the yield in the second year of high yield in Example 1 was more than nine times that of conventionally cultivated Comparative Example 1. Comparative Examples 2 and 3, compared to Example 1, showed lower tender shoot yields from the year of transplanting to the fourth year.

[0065] Figure 3 This is a diagram showing the growth of young shoots of *Ilex crenata* after pruning and leaf removal in Example 1. Figure 3 It is evident that after pruning and leaf removal, the plant's new shoots grow vigorously, but produce fewer flowers. Figure 4 The image shown is of the flowering of *Ilex crenata* in Comparative Example 1, without pruning or leaf removal. Figure 4 As can be seen, in conventional cultivation methods, without pruning and leaf removal, the plant grows abundantly with flowers but produces no new shoots, with all nutrients being devoted to flowering. This comparison demonstrates that the cultivation method of this invention can achieve rapid and abundant production of *Arundinaria rubra*, effectively increasing the yield of new shoots and quickly realizing the economic benefits of *Arundinaria rubra* cultivation.

[0066] 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, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
