Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal material planting, and specifically to a method for efficiently planting dendrobium (Dendrobium officinale) by using a vertical stone matrix, aiming to solve the problems of frequent pests and diseases, poor ventilation, insufficient mineral absorption, etc. in traditional planting methods, and to improve the yield and quality of dendrobium (Dendrobium officinale). Background Art

[0002] In the traditional method of planting Dendrobium officinale, common substrates include bark, sawdust, soil, greenhouse fields, etc. Although these methods can meet the basic growth needs of Dendrobium officinale to a certain extent, there are many shortcomings.

[0003] First, although bark and sawdust as substrates provide a certain degree of air permeability and water retention, they are easy to breed various pathogens and pests, increasing the difficulty and cost of pest control. At the same time, these substrates will gradually decompose during long-term use, resulting in nutrient loss and destruction of the substrate structure, which is not conducive to the long-term growth of Dendrobium. Secondly, although greenhouse field planting is convenient for management and control of environmental conditions, there is often a problem of poor ventilation. In particular, when a thick layer of bark is laid underground, it hinders air circulation, making it impossible for the roots to obtain sufficient oxygen, which in turn affects the growth and quality of Dendrobium. In addition, the environmental conditions in the greenhouse are often different from those in the natural environment, and it is difficult to completely simulate the natural growth environment of Dendrobium, resulting in a decrease in the stress resistance and medicinal quality of Dendrobium.

[0004] Furthermore, as an orchid, Dendrobium's unique growth habit requires the roots to be closely attached to a hard substrate in order to absorb minerals and water. However, the substrate in traditional planting methods often cannot meet this requirement, resulting in poor root growth of Dendrobium, which in turn affects its overall growth and medicinal value. Especially in greenhouse field planting, due to the soft substrate, it is difficult for the roots to be fixed, and it is even more difficult to absorb the various minerals and essences of the sun and the moon on the stone.

[0005] In view of the above problems, the present invention proposes a method for planting Dendrobium officinale based on a vertical stone matrix. The method simulates the natural growth environment of Dendrobium officinale and uses a vertical stone matrix to provide a stable attachment point and sufficient mineral source for the root system. At the same time, through reasonable drilling and cork filling technology, good air permeability and water retention of the root system are ensured. In addition, the method also pays attention to the details of water management and pest control, so that Dendrobium officinale can grow in a healthier and more stable environment, thereby improving its yield and quality. Summary of the invention

[0006] The present invention aims to provide a vertical stone substrate planting method, which can optimize the root growth conditions of dendrobium by simulating the natural growth environment of dendrobium, promote mineral absorption, reduce pests and diseases, and realize high-yield and high-quality cultivation of dendrobium (dendrobium officinale).

[0007] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0008] 1. Preparation of vertical stone matrix: select large stones with hard texture and no cracks, the size of which should be stable and easy to operate. Granite, limestone and other stones rich in trace elements are preferred.

[0009] 2. Drilling holes in the stone and filling with wooden plugs: Use an impact drill with a diameter of 8mm to drill holes evenly on the four sides and top of the stone, with a hole depth of 20±2mm and a hole spacing of 12±1cm to ensure that the roots have enough space to attach. Then, use a round wooden plug with a diameter slightly smaller than the hole diameter (7.8-7.9mm) to gently knock it into the hole with a hammer. The wooden plug needs to be soaked in a sterilizing solution in advance to prevent infection.

[0010] 3. Planting of Dendrobium seedlings: Select two-year-old Dendrobium (Dendrobium officinale) seedlings with strong growth and well-developed root systems. Use special tie wraps to gently attach their roots around the pre-made wooden plugs on the stones. The tie wraps should be of moderate tightness to ensure that the roots are fixed without affecting growth.

[0011] 4. Water management and maintenance: Keep the stone slightly moist at the beginning. Water can be added by spraying or drip irrigation to avoid water accumulation. Check the root growth regularly and adjust the tightness of the tie in time.

[0012] 5. Root expansion and harvesting: After about 10 months, the roots of the Dendrobium will be tightly wrapped around the stone. At this time, you can cut off the tie and let it grow naturally. After five years, you can select the old stems every year and leave the new shoots to continue growing, so as to achieve sustainable utilization.

[0013] Beneficial effects of the present invention:

[0014] Compared with the traditional planting method, the present invention has the following beneficial effects:

[0015] 1. Optimize the growth environment: The use of vertical stone substrate simulates the natural growth conditions of Dendrobium, providing a stable attachment point and rich mineral sources for the roots. This substrate not only has good air permeability, but also can maintain appropriate soil moisture, which is conducive to the healthy growth of the root system and the absorption and utilization of nutrients.

[0016] 2. Improve yield and quality: The vertical stone matrix planting method can significantly improve the yield and quality of Dendrobium. Because the root system can be closely attached to the stone, it can fully absorb minerals and the essence of the sun and the moon, making the growth of Dendrobium stronger and the content of medicinal ingredients higher. At the same time, this method can also reduce the occurrence of diseases and pests, reduce the use of pesticides, and further improve the quality and safety of Dendrobium.

[0017] 3. Saving resources and costs: Compared with traditional planting methods, the method of the present invention is simpler and more efficient in terms of substrate preparation and maintenance management. Stone, as a natural resource, is easy to obtain and renewable, which reduces the cost of planting. At the same time, since the occurrence of pests and diseases and the use of pesticides are reduced, the cost of pest control is also saved.

[0018] 4. Promote sustainable development: The vertical stone matrix planting method not only improves the yield and quality of Dendrobium, but also promotes the sustainable development of the Chinese herbal medicine industry. This method can reduce the occupation and damage of land and protect the ecological environment. At the same time, by recycling resources such as stones and corks, the effective utilization and circular development of resources are achieved.

[0019] 5. Enhanced stress resistance and adaptability: Since the vertical stone matrix planting method simulates the natural growth environment of Dendrobium, it enables Dendrobium to better adapt to changes in the natural environment and enhances its stress resistance and adaptability. This is conducive to the planting and promotion of Dendrobium in a wider range of regions and climatic conditions.

[0020] The method for planting Dendrobium officinale (Dendrobium candidum) based on a vertical stone matrix proposed in the present invention has significant beneficial effects, not only improving the yield and quality of Dendrobium officinale, but also promoting the sustainable development of the Chinese medicinal materials industry, and has broad application prospects and promotion value.

Set up sunshade nets and ventilation equipment in the greenhouse to control light and temperature.

[0046] 3. Maintenance and management: Water regularly to keep the substrate moist, but avoid waterlogging. Use organic fertilizer for topdressing, and pay attention to the occurrence of diseases and pests, and take preventive measures in time.

[0047] Comparative Example 2: Pure soil matrix greenhouse planting

[0048] 1. Substrate preparation: Choose fertile, loose, and well-ventilated soil as the substrate, cultivate it deeply, and remove weeds and stones. Lay a layer of plastic film in the greenhouse, and then evenly spread the soil on the film, with a thickness of about 20 cm.

[0049] 2. Planting process: dig a planting hole of appropriate size on the soil substrate, plant the Dendrobium seedlings in the hole, backfill the soil and compact it lightly. Water thoroughly to ensure that the roots are in close contact with the soil.

[0050] 3. Maintenance and management: Water according to soil moisture and the growth needs of Dendrobium to avoid excessive moisture or dryness. Use compound fertilizer for topdressing, and pay attention to ventilation to reduce the humidity in the greenhouse and the occurrence of pests and diseases.

[0051] Comparative Example 3: Mixed substrate (sawdust + perlite + vermiculite) greenhouse planting

[0052] 1. Substrate preparation: Mix the screened and sterilized sawdust, perlite and vermiculite in a certain ratio (2:1:1) as the planting substrate for Dendrobium. Lay a layer of plastic film in the greenhouse, and then evenly spread the mixed substrate on the film with a thickness of about 15 cm.

[0053] 2. Planting process: dig a planting hole of appropriate size on the mixed substrate, plant the Dendrobium seedlings in the hole, backfill the mixed substrate and compact it lightly. Water thoroughly to ensure that the roots are in close contact with the substrate.

[0054] 3. Maintenance and management: Water according to the water retention of the mixed substrate and the growth requirements of Dendrobium to avoid excessive moisture in the substrate that may cause root rot. Use fertilizers containing a variety of trace elements for topdressing to promote the growth and development of Dendrobium. At the same time, strengthen ventilation in the greenhouse, reduce humidity, and reduce the occurrence of diseases and insect pests.

[0055] The comparison data obtained by using the dendrobium planted by the embodiment and the comparative example are as follows:

[0056]

[0057]

[0058] The table shows the planting data of Dendrobium officinale of three embodiments and three comparative examples. In the embodiment, the average fresh stem weight per plant is high, and the yield is also correspondingly high, reaching a range of 180 to 200 kilograms per mu. At the same time, the Dendrobium officinale in the embodiment contains relatively rich trace elements, moderate plant height, and high leaf area index, indicating that the growth state of the plant is good and the photosynthesis ability is strong. In addition, the incidence of diseases and insect pests in the embodiment is also relatively low, which effectively controls the occurrence of diseases and insect pests.

[0059] In contrast, the data in the comparative example are relatively poor. The average fresh stem weight per plant is low, the yield is correspondingly reduced, and the content of trace elements, plant height, leaf area index and other indicators are generally lower than those in the embodiment. At the same time, the incidence of pests and diseases in the comparative example is high, and the traditional planting method is relatively backward in multiple parameters such as yield compared to the planting method in the embodiment.
