Description

Technical Field

[0001] The invention relates to the technical field of roxburghii planting, and in particular to a bag-type roxburghii cultivation method capable of reducing the risk of plant disease infection. Background Art

[0002] Golden thread vine is a perennial herb with extensive medicinal value among the people. At present, there are two main methods of artificially cultivating golden thread vine in various places: greenhouse cultivation and under-forest cultivation. Greenhouse cultivation creates suitable temperature, humidity and light conditions for the growth and development of golden thread vine by building greenhouse facilities and setting up shade nets. Under-forest cultivation utilizes the natural underforest environment conditions, sets up shade nets between trees, and plants under the trees.

[0003] According to a disclosed method for cultivating golden thread vine in a bag and its cultivation equipment (Announcement No.: CN117958089A), the golden thread vine is cultivated successively in the above application. First, a sufficient amount of cultivation medium is filled in the cultivation bag, and the golden thread vine seedlings are cultivated for the first time using the cultivation medium. The golden thread vine seedlings are cultivated for the second time in the cultivation room. After the golden thread vine seedlings grow to meet the conditions for greenhouse cultivation, the golden thread vine seedlings are transferred to the planting greenhouse for the third cultivation.

[0004] However, in the actual implementation of the above planting method, since the golden thread vines are not separated, when one golden thread vine is infected with diseases and insect pests, it is easy to transmit the diseases to the surrounding golden thread vines, thereby affecting the growth of the golden thread vine and causing property losses. In view of this, we proposed a bag-type golden thread vine cultivation method that can reduce the infection of the plants. Summary of the invention

[0005] The object of the present invention is to provide a method for cultivating bag-type golden thread vine which can reduce the risk of plant disease, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a bag-type golden thread vine cultivation method capable of reducing plant disease infection, comprising the following steps: S1. Prepare the matrix soil and disinfect the matrix soil; S2, seedling treatment; S3, the seedlings are planted in the cultivation bag; S4, moving the cultivation bag to the greenhouse; S5, transplant seedlings to the forest floor; S6. Determine whether pests and diseases are present; S6.1. Isolate and remove infected plants if pests and diseases occur; S6.2. Harvest if there is no disease or insect pest.

[0007] Preferably, the matrix soil is a mixture of peat soil, perlite, decomposed sawdust, organic compost, diatomaceous earth, etc., wherein peat soil accounts for 50%, perlite accounts for 20%, decomposed sawdust accounts for 15%, organic compost accounts for 10%, and diatomaceous earth accounts for 5%. Peat soil has a natural fibrous structure, which can maintain the fluffiness of the matrix, which is conducive to the free growth of the root system, and provides looseness and air permeability with perlite. The perlite structure is porous and can quickly remove excess water to avoid root rot caused by water accumulation in the root system. Diatomaceous earth will slowly release water after absorbing water, store a large amount of water, reduce the need for frequent watering, and increase the permeability of the matrix. Organic compost is rich in trace elements and organic matter, can slowly release nutrients, and provide long-term nutrient supply for plants. Peat soil is weakly acidic, and diatomaceous earth has a certain pH buffering capacity. After mixing, the pH value of the matrix can be stabilized at 5.5-6.5, which is suitable for the growth needs of golden thread vine.

[0008] Preferably, the matrix soil is disinfected by high-temperature sterilization at a temperature of 120°C for more than 30 minutes. High-temperature sterilization at 120°C can effectively kill potential pathogens, fungal spores, pest eggs and other harmful microorganisms in the matrix, and prevent the disease from spreading to the root system of the plant. It is particularly suitable for crops such as Anoectochilus roxburghii that are susceptible to soil-borne diseases, and reduces the risk of seedling diseases. At the same time, high temperature can destroy the activity of weed seeds in the matrix, reduce the competition between weeds and Anoectochilus roxburghii for water and nutrients, and is beneficial to the healthy growth of the plant. After the high-temperature sterilization, an appropriate amount of antibacterial agent is added to the matrix soil, and the antibacterial agent is a wood ash extract or carbendazim. The addition of the antibacterial agent can further inhibit the secondary reproduction of pathogens and provide long-term protection for the plant.

[0009] Preferably, the seedling treatment is to soak the seedlings in 0.1% potassium permanganate solution or a special antibacterial agent for 5 minutes, then rinse the seedlings with clean water, and dry the seedlings after rinsing with clean water. Potassium permanganate is a strong oxidant, and its 0.1% dilute solution can effectively kill pathogens, fungal spores and pest eggs attached to the surface of seedlings, prevent soil-borne or contact infectious diseases caused by pathogens carried by seedlings, kill pathogens on the surface of seedlings, reduce the incidence of diseases and pests, and improve the health level of seedlings.

[0010] Preferably, substrate soil is placed in the cultivation bag with a thickness of 5-7 cm, and the humidity is maintained at 50%-60%, and the pH value is 5.5-6.0. Slow-release organic fertilizer is added to the substrate soil. The bag body of the cultivation bag has holes with a hole diameter of 1-2 cm and a spacing of 5-8 cm. The holes in the bag body can promote air circulation inside the substrate, prevent anaerobic conditions caused by a closed environment, ensure the health of the root system, accelerate the discharge of excess water, and avoid damage to the root system caused by accumulated water.

[0011] Preferably, the seedlings are planted in a cultivation room. The planting method is to insert the seedlings into the substrate soil and gently compact the substrate soil to ensure that the roots of the seedlings are in close contact with the substrate, providing stable support and promoting the absorption of water and nutrients by the roots. The cultivation bags are placed on independent brackets with a spacing of 10 - 15 cm between the brackets. Placing the cultivation bags on the brackets isolates them from the ground, which helps with drainage and ventilation and prevents excessive moisture in the substrate, root hypoxia, or diseases caused by water accumulation at the bottom of the bags.

[0012] Preferably, 15 - 20 days after transplanting the seedlings into the greenhouse for cultivation, the temperature in the greenhouse is controlled at 20 - 25°C, the humidity is maintained at 80% - 90%, and the shading rate is 70% - 80%. An insect-proof net is added in the greenhouse, and the aperture of the insect-proof net is less than 0.5 mm. The seedlings are placed in a "pin" shape. This layout allows each seedling to receive uniform light, avoiding insufficient light or competition effects caused by overlap. The cultivation bags are spaced 10 - 15 cm apart. The planting area of the seedlings is divided into small units, and each small unit contains 10 - 20 seedlings. Managing the seedlings in zones can prevent the rapid spread of pests and diseases in the event of an outbreak in large-scale planting. A partition is set in the middle of each small unit, and the partition is made of PVC board or bamboo fiber board. The height of the partition is 5 - 10 cm above the substrate soil, and the surface of the partition is sprayed with a peppermint oil solution. When pests and diseases occur, the partition can limit their spread to the entire planting area, which is conducive to precise prevention and control.

[0013] Preferably, a simple protective frame is built in the planting area under the forest and covered with a fine-mesh nylon net, which can prevent birds from pecking at Anoectochilus roxburghii and the invasion of pests, avoid direct strong light in the forest from damaging the plants, and create a suitable scattered light environment. A rat-proof net is arranged around the ground. The planting substrate under the forest is disinfected in advance and uses a substrate similar to that in seedling cultivation, such as humus soil and perlite, to maintain loose air permeability and weak acidity, ensuring a pH value of 5.5 - 6.5. The time for transplanting the seedlings under the forest is 30 - 40 days after seedling cultivation. After 30 - 40 days, the seedlings have completed initial root development in the greenhouse, and the roots already have a certain ability to absorb water and nutrients, enabling them to better adapt to the environment under the forest. The planting conditions under the forest are close to the natural growth environment of Anoectochilus roxburghii, with more suitable temperature, humidity, and light, which can promote the natural growth of the plants. The natural humus is rich in the forest environment, combined with the artificially added substrate, which is more conducive to Anoectochilus roxburghii absorbing nutrients and promoting growth. Compared with greenhouse planting, the management cost under the forest is lower, reducing the dependence on artificial control.

[0014] Preferably, the isolation and removal of infected plants are divided into rapid isolation, enhanced protection isolation and environmental disinfection. The rapid isolation is to seal the diseased plants and their substrates with plastic bags as soon as possible, and then move them out of the original planting area together with the cultivation bags. After the diseased plants and the substrate are sealed, the pathogens cannot spread to the surrounding environment through the air, the substrate or the surface of the plants. A temporary isolation barrier, such as a plastic film or cardboard, is set at the original location. The temporary isolation barrier prevents the pathogens from spreading to adjacent areas through wind, water or contact. The enhanced protection isolation is centered on the infected plants, and all plants within a radius of 30-50 cm are set up in a temporary isolation area, such as increasing the isolation area. Away from the board or protective cover, adjacent plants are easily affected by pathogens, and plants in the potential infection range are separated from healthy plants for centralized monitoring and treatment. The establishment of an isolation area reduces the risk of cross-regional transmission of pathogens. The environmental disinfection uses 0.5%-1% sodium hypochlorite solution to thoroughly sterilize the support, ground and related tools at the original position of the diseased plant and the surrounding area. Sodium hypochlorite is a powerful fungicide that can quickly kill viruses, bacteria and fungi, ensuring that the pathogens cannot continue to survive after physical isolation. Through multiple isolation and disinfection measures, the area where the disease occurs is accurately controlled within the smallest range, protecting healthy plants planted over a large area.

[0015] Preferably, the substrate soil is sterilized again at high temperature 4-6 months after the harvesting of the plants. The substrate soil is an important input for the cultivation of golden thread vine. Reuse reduces the demand for purchasing new substrate soil and reduces production costs. The substrate soil after sterilization can be restored to health and continue to be used without reducing its effect.

[0016] Compared with the prior art, the present invention provides a method for cultivating bag-type golden thread vine that can reduce the risk of plant disease infection, and has the following beneficial effects: 1. The bag-type golden thread vine cultivation method that can reduce the risk of plant disease infection can effectively kill potential pathogens, fungal spores, pest eggs and other harmful microorganisms in the matrix by pre-disinfecting the matrix soil and seedlings in advance, prevent the disease from spreading to the root system of the plant, eliminate the pathogens, fungal spores and pest eggs attached to the surface of the seedlings, prevent soil-borne or contact infectious diseases caused by pathogens carried by the seedlings, and reduce the risk of seedling diseases. When diseases and insect pests occur, the area where the disease occurs is accurately controlled within the minimum range through multiple isolation and disinfection measures, protecting healthy plants planted in a large area. The seedlings are first grown in a greenhouse. After 30-40 days, the seedlings complete the initial rooting and development in the greenhouse, and the root system has a certain ability to absorb water and fertilizer. At this time, they are transplanted under the forest to reduce the cost of planting, adapt to natural light, temperature and humidity changes and ecological pressure, and help cultivate healthy plants.

[0017] 2. The bag-type golden thread vine cultivation method which can reduce the disease infection of the plant, adds a proper amount of antibacterial agent to the substrate soil, the antibacterial agent is a wood ash extract or carbendazim, so as to improve the sustained antibacterial ability of the substrate soil, inhibit the secondary reproduction of pathogens, and provide long-term protection for the plant. The alkaline substance in the wood ash extract has a bactericidal effect, can adjust the pH value of the substrate, and reduce the reproduction of fungi in an acidic environment.

[0018] 3. The bag-type golden thread vine cultivation method can reduce the risk of plant disease. After harvesting the golden thread vine, the substrate soil is sterilized again at high temperature. The substrate soil after sterilization can be restored to health and can continue to be used without reducing its effect. The repeated use reduces the demand for purchasing new substrate soil, reduces production costs, and reduces agricultural waste generated by the substrate soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0020] like Figure 1 As shown, the present invention provides a technical solution: a bag-type golden thread vine cultivation method that can reduce the risk of plant disease, comprising the following steps: S1. Prepare the matrix soil and disinfect the matrix soil; S2, seedling treatment; S3, the seedlings are planted in the cultivation bag; S4, moving the cultivation bag to the greenhouse; S5, transplant seedlings to the forest floor; S6. Determine whether pests and diseases are present; S6.1. Isolate and remove infected plants if pests and diseases occur; S6.2. Harvest if there is no disease or insect pest.

[0021] Among them, the matrix soil is a mixture of peat soil, perlite, decomposed sawdust, organic compost, diatomaceous earth, etc., of which peat soil accounts for 50%, perlite accounts for 20%, decomposed sawdust accounts for 15%, organic compost accounts for 10%, and diatomaceous earth accounts for 5%. Peat soil has a natural fibrous structure, which can maintain the fluffiness of the matrix and is conducive to the free growth of roots. It provides looseness and air permeability with perlite. Perlite has a porous structure and can quickly remove excess water to avoid root rot caused by water accumulation in the root system. Diatomaceous earth will slowly release water after absorbing water, store a large amount of water, reduce the need for frequent watering, and increase the permeability of the matrix. Organic compost is rich in trace elements and organic matter, which can slowly release nutrients and provide long-term nutrient supply for plants. Peat soil is weakly acidic, and diatomaceous earth has a certain pH buffering capacity. After mixing, the pH value of the matrix can be stabilized at 5.5-6.5, which is suitable for the growth needs of golden thread vine.

[0022] Among them, the disinfection of the matrix soil adopts high-temperature sterilization, the temperature is 120℃, and the sterilization time is more than 30 minutes. The high-temperature sterilization of 120℃ can effectively kill potential pathogens, fungal spores, pest eggs and other harmful microorganisms in the matrix, and prevent the disease from spreading to the root system of the plant. It is particularly suitable for crops such as golden thread vine that are susceptible to soil-borne diseases, reducing the risk of seedling diseases. At the same time, high temperature can destroy the activity of weed seeds in the matrix, reduce the competition between weeds and golden thread vine for water and nutrients, and is beneficial to the healthy growth of plants. After high-temperature sterilization, an appropriate amount of antibacterial agent is added to the matrix soil. The antibacterial agent is wood ash extract or carbendazim. The addition of antibacterial agent can further inhibit the secondary reproduction of pathogens and provide long-term protection for plants.

[0023] Among them, the seedling treatment is to soak the seedlings in 0.1% potassium permanganate solution or special antibacterial agent for 5 minutes, then rinse the seedlings with clean water, and dry the seedlings after rinsing with clean water. Potassium permanganate is a strong oxidant, and its 0.1% dilute solution can effectively kill pathogens, fungal spores and pest eggs attached to the surface of seedlings, prevent soil-borne or contact infectious diseases caused by pathogens carried by seedlings, kill pathogens on the surface of seedlings, reduce the incidence of diseases and pests, and improve the health level of seedlings.

[0024] Among them, substrate soil is placed in the cultivation bag with a thickness of 5-7cm, and the humidity is maintained at 50%-60%, and the pH value is 5.5-6.0. Slow-release organic fertilizer is added to the substrate soil. The bag body of the cultivation bag has holes with a hole diameter of 1-2cm and a spacing of 5-8cm. The holes in the bag body can promote air circulation inside the substrate, prevent anaerobic conditions caused by a closed environment, ensure the health of the root system, accelerate the discharge of excess water, and avoid damage to the root system caused by stagnant water.

[0025] Among them, the seedlings are planted in the cultivation room. The planting method is to insert the seedlings into the substrate soil and gently compact the substrate soil to allow the seedling roots to closely contact the substrate, provide stable support, and promote the root system to absorb water and nutrients. The cultivation bags are placed on independent brackets with a spacing of 10-15cm. The cultivation bags are placed on the brackets to isolate them from the ground, which helps drainage and ventilation, and prevents water accumulation at the bottom of the bag, which may cause excessive moisture in the substrate, lack of oxygen in the roots, or disease.

[0026] Among them, 15 - 20 days after transplanting the seedlings into the greenhouse for seedling cultivation, the temperature in the greenhouse is controlled at 20 - 25 °C, the humidity is maintained at 80% - 90%, the shading rate is 70% - 80%, an insect-proof net is added in the greenhouse, the aperture of the insect-proof net is less than 0.5 mm, the seedlings are placed in a "pin" shape. The "pin" shape layout can enable each seedling to receive light evenly, avoiding insufficient light or competition effect caused by overlap. The cultivation bags are spaced 10 - 15 cm apart. The planting area of the seedlings is divided into small units, and each small unit includes 10 - 20 seedlings. The seedlings are managed in different areas to avoid the rapid spread of pests and diseases once they occur in large-area planting. A partition is set in the middle of each small unit, and the material of the partition is PVC board or bamboo fiber board. The height of the partition is 5 - 10 cm above the substrate soil. The surface of the partition is sprayed with peppermint oil solution. When pests and diseases occur, the partition can limit their spread to the entire planting area, which is beneficial for precise prevention and control.

[0027] Among them, a simple protective frame is built in the underforest planting area and covered with a fine-mesh nylon net, which can prevent birds from pecking at Anoectochilus roxburghii and pests from invading, avoid direct strong light in the underforest from damaging the plants, create a suitable scattered light environment, and anti-mouse nets are arranged around the ground. The planting substrate in the underforest is disinfected in advance and uses a substrate similar to that in seedling cultivation, such as humus soil and perlite, to maintain loose air permeability and weak acidity, ensuring that the pH value is between 5.5 and 6.5. The time for transplanting the seedlings to the underforest is 30 - 40 days after seedling cultivation. After 30 - 40 days, the seedlings have completed initial root development in the greenhouse, and the roots already have a certain ability to absorb water and nutrients, and can better adapt to the underforest environment. The underforest planting conditions are close to the natural growth environment of Anoectochilus roxburghii, and the temperature, humidity and light are more suitable, which can promote the natural growth of the plants. The natural humus in the underforest environment is rich, combined with artificial addition of substrate, which is more conducive to Anoectochilus roxburghii absorbing nutrients and promoting growth. Compared with greenhouse planting, the management cost in the underforest is lower, reducing the dependence on artificial control.

[0028] Among them, isolation and removal of infected plants are divided into rapid isolation, enhanced protective isolation and environmental disinfection. Rapid isolation is to seal the diseased plants and their substrates with plastic bags as soon as possible, and move them out of the original planting area together with the cultivation bags. After sealing the diseased plants and substrates, the pathogens cannot spread to the surrounding environment through the air, substrate or plant surface. A temporary isolation barrier, such as plastic film or cardboard, is set up at the original location. The temporary isolation barrier prevents the pathogens from spreading to adjacent areas through wind, water or contact. Enhanced protective isolation takes the infected plants as the center, and all plants within a radius of 30-50 cm are set up in a temporary isolation area, such as adding isolation boards or Protective cover, adjacent plants are easily affected by pathogens, plants in the potential infection range are separated from healthy plants, which is convenient for centralized monitoring and treatment. The establishment of isolation areas reduces the risk of cross-regional transmission of pathogens. Environmental disinfection uses 0.5%-1% sodium hypochlorite solution to thoroughly sterilize the bracket, ground and related tools at the original location and surrounding area of ​​the diseased plants. Sodium hypochlorite is a powerful fungicide that can quickly kill viruses, bacteria and fungi, ensuring that pathogens cannot continue to survive after physical isolation. Through multiple isolation and disinfection measures, the area where the disease occurs is precisely controlled to the smallest range, protecting healthy plants planted over a large area.

[0029] Among them, the substrate soil is sterilized again at high temperature 4-6 months after the plant is cultivated. The substrate soil is an important input for the cultivation of golden thread vine. Reuse reduces the demand for purchasing new substrate soil and reduces production costs. The substrate soil after sterilization can be restored to health and continue to be used without reducing its effect.

[0030] In one embodiment of the present invention, the substrate soil and seedlings are pre-disinfected to effectively kill potential pathogens, fungal spores, pest eggs and other harmful microorganisms in the substrate, prevent the disease from spreading to the root system of the plant, eliminate pathogens, fungal spores and pest eggs attached to the surface of the seedlings, prevent soil-borne or contact infectious diseases caused by pathogens carried by the seedlings, and reduce the risk of seedling diseases. When pests and diseases occur, the area where the disease occurs is accurately controlled within the minimum range through multiple isolation and disinfection measures to protect healthy plants planted over a large area. The seedlings are first grown in a greenhouse. After 30-40 days, the seedlings complete the initial rooting and development in the greenhouse, and the root system has a certain ability to absorb water and fertilizer. At this time, they are transplanted under the forest to reduce the cost of planting, adapt to natural light, temperature and humidity changes, and ecological pressure, which is conducive to the cultivation of healthy plants.

[0031] In order to improve the continuous antibacterial ability of the matrix soil, an appropriate amount of antibacterial agent is added to the matrix soil after high-temperature sterilization. The antibacterial agent is wood ash extract or carbendazim. The addition of antibacterial agent can further inhibit the secondary reproduction of pathogens and provide long-term protection for the plants.

[0032] In addition, in order to reduce agricultural waste generated by the matrix soil, the matrix soil is sterilized again at high temperature after harvesting the golden thread vine. The matrix soil is an important input for the cultivation of golden thread vine. Reuse reduces the demand for purchasing new matrix soil and reduces production costs. The matrix soil after sterilization can be restored to health and continue to be used without reducing its effectiveness.

[0033] In the present invention, when in use, substrate soil is prepared, the substrate soil is disinfected, and then seedlings are treated, the surface of the seedlings is disinfected, the seedlings are planted in a cultivation bag, and then the cultivation bag is moved to a greenhouse. 30-40 days after the seedlings are cultivated, the seedlings are transplanted under the forest. If pests and diseases occur, the infected plants are isolated and removed. After 4-6 months of plant cultivation, the golden thread vine is harvested.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
