Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural planting technology, and more specifically, to a method for alleviating continuous cropping problems in Gastrodia elata. Background Technology
[0002] Gastrodia elata is a traditional and precious Chinese medicinal herb. Due to its high medicinal, health-promoting, and edible value, it has become a hot topic in the development of "medicine and food from the same source." Currently, Gastrodia elata is mainly produced through artificial cultivation, but because it belongs to the rhizome category of medicinal herbs that cannot be continuously cropped, the development of the Gastrodia elata cultivation industry is severely restricted.
[0003] Continuous cropping (ROC) of Gastrodia elata is the most prominent and widespread production problem in its artificial cultivation, manifesting as a sharp drop in yield, deterioration in quality, and outbreaks of diseases, severely restricting the sustainable development of the industry. Its core cause stems from the unique symbiotic growth habits of Gastrodia elata and the chain reaction of soil microecological deterioration, leading to decreased soil quality, nutrient imbalance, soil acidification, and exacerbation of soil-borne diseases. Currently, most methods to alleviate continuous cropping problems in Gastrodia elata cultivation involve land replacement, crop rotation (3-4 years), soil improvement (application of organic fertilizer and quicklime), and renewal of microbial strains, but these still suffer from high costs and complex operations.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention
[0005] In view of the problems in related technologies, the present invention proposes a method to alleviate the problem of continuous planting of Gastrodia elata, so as to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by the present invention is as follows: One method to alleviate the problem of replanting Gastrodia elata includes: S1. Using Fagaceae tree species as fungal material, the fungal material is pretreated and then soaked in a pre-prepared diluted fungal agent. Culture holes are dug, the soaked fungal material is placed in the culture holes, and Armillaria mellea is placed in the culture holes to obtain fungal material. S2. In spring, dig several planting holes of a predetermined size and spacing on the selected land. Lay leaves or humus in the planting holes, spray the predetermined amount of diluted fungal agent evenly, and then place the fungal material evenly before planting the seed hemp. Cover with soil and then lay broad-leaved leaves. S3. After planting hemp seeds, perform a bacterial treatment, wherein the bacterial treatment involves spraying or dripping a diluted bacterial agent onto the surface of the planting hole.
[0007] Preferably, the pretreatment of the fungal material includes: Cut logs of 60cm to 80cm in length from the raw material for fungal cultivation. After drying the logs for a week, make several fish-scale-shaped notches on the surface of the dried logs. The fish-scale-shaped notches are spaced 5cm apart on the surface of the logs and reach the xylem.
[0008] Preferably, the dosage of the diluted bacterial agent, which is sprayed evenly, is 100 ml per square meter.
[0009] Preferably, the diluted bacterial agent is prepared by mixing Enterobacter AV1 bacterial agent and water at a volume ratio of 1:99.
[0010] Preferably, the soaking time of the pretreated fungal material in the diluted fungal agent is 4 hours.
[0011] Preferably, the cultivation pit is set in a high, well-drained, and flat sandy loam or loam soil, and the depth of the cultivation pit is 40cm to 80cm and the width is 60cm to 80cm.
[0012] Preferably, the Armillaria mellea inoculum is placed in the fish-scale-shaped notch, and the Armillaria mellea inoculum is a third-level solid inoculum, with a placement amount of 0.6 kg per square meter.
[0013] Preferably, the planting hole is 80cm to 100cm long, 60cm wide, and 30cm deep, and the spacing between each planting hole is 50cm.
[0014] Preferably, the thickness of the leaves or humus in the planting hole is 3cm, the number of hemp seeds placed is 6 to 10, and the thickness of the broad-leaved leaves after covering with soil is 2cm to 3cm.
[0015] Preferably, spraying or dripping the diluted microbial agent onto the ridge surface of the planting hole includes: on cloudy days or evenings 30 days and 90 days after planting, using the diluted microbial agent at a dosage of 100 ml per square meter, evenly spraying or dripping it onto the ridge surface of the planting hole.
[0016] The beneficial effects of this invention are as follows: 1. This invention improves the colonization ability of beneficial microorganisms in the Gastrodia elata cultivation system by introducing Enterobacter AV1 bacterial agent during the treatment of fungal materials, planting treatment and post-planting fungal supplementation, thereby improving the micro-ecological environment in continuously cropped plots and reducing the adverse effects of continuous cropping obstacles on the growth of Gastrodia elata.
[0017] 2. By applying a microbial treatment after planting hemp, the diluted microbial agent can continuously act on the surface of the planting holes and ridges, which can replenish the number of beneficial microorganisms during cultivation, maintain the stability of the microbial community structure, and thus alleviate problems such as microecological imbalance, soil acidification and nutrient disorder in soils with continuous cropping.
[0018] 3. The operation process of this invention is simple. It only requires the application of diluted Enterobacter auriculi AV1 in the stages of mycelium treatment, planting treatment and post-planting management. It does not require complicated equipment and high-cost improvement measures, which can reduce the improvement cost of continuous cropping plots and improve the production efficiency and economic benefits of Gastrodia elata cultivation.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1 As shown, a method for alleviating continuous cropping of Gastrodia elata according to an embodiment of the present invention includes: Example 1 A method for alleviating continuous cropping of Gastrodia elata includes the following steps: S1. Using Fagaceae tree species as the raw material for mycelium cultivation, the raw material is cut into 60cm long sections according to the planting ridge surface. After drying the sections for one week, fish-scale-like notches are cut every 5cm on the sections, reaching the xylem. 1L of Enterobacter AV1 inoculum agent is mixed evenly with 99L of water to obtain a 100-fold diluted inoculum agent. The treated sections are soaked in the 100-fold diluted inoculum agent for 4 hours, then removed and set aside for use. Select a high-lying, well-drained, and flat sandy loam soil as the cultivation site. Dig cultivation pits 40cm deep and 60cm wide, and evenly place the soaked logs in the cultivation pits. Place Armillaria mellea inoculum at the fish-scale-shaped notches of the logs. The inoculum used is a grade III solid inoculum, with a dosage of 0.6kg / m. After placement, cover with soil so that the surface of the cultivation pit has a turtle-back shape. The fungal material is obtained after six months of cultivation.
[0024] It should be noted that during the cultivation process, if there is a rainy day with rainfall exceeding 50 mm within 24 hours, supplement the bacteria 1-2 times as needed according to the supplementation treatment method.
[0025] In addition, the excavation of cultivation pits was carried out in accordance with the Technical Specifications for Gastrodia elata Production (DB41 / T 451-2023).
[0026] S2. In March, dig several planting holes on the selected land. The planting holes should be 80cm long, 60cm wide, and 30cm deep, with a spacing of 50cm between holes. Lay a 3cm layer of leaves in the planting holes and evenly spray a 100-fold diluted fungal agent at a dosage of 100ml / m². Then, evenly place the cultivated fungal material in the planting holes. Depending on the size of the fungal material, place 6 seed piles around it. After placement, cover with loose soil to form a turtle-back shape, and then lay a 2cm layer of broad-leaved leaves to retain moisture and prevent weeds.
[0027] S3. Choose a cloudy day or evening, and apply the bacteria once each 30 days and 90 days after planting the hemp. Each time, apply 100ml / m of diluted bacteria solution and spray it evenly on the surface of the planting hole. It should be noted that after planting and inoculating the plant in spring, the harvest should be carried out in mid-November of the same year on a sunny, rainless day. When harvesting, dig a 30cm deep trench along one end of the ridge of the planting hole, digging layer by layer from shallow to deep, and handling the plant gently to avoid damaging the skin of the Gastrodia elata.
[0028] Example 2 A method for alleviating continuous cropping of Gastrodia elata includes the following steps: S1. Using Fagaceae tree species as the raw material for mycelium cultivation, the raw material is cut into 80cm long sections according to the planting ridge surface. After drying the sections for one week, fish-scale-like notches are cut every 5cm on the sections, reaching the xylem. 1L of Enterobacter AV1 inoculum agent is mixed evenly with 99L of water to obtain a 100-fold diluted inoculum agent. The treated sections are soaked in the 100-fold diluted inoculum agent for 4 hours, then removed and set aside for use. Select a high-lying, well-drained, and flat sandy loam soil as the cultivation site. Dig cultivation pits 80cm deep and 80cm wide, and evenly place the soaked logs in the cultivation pits. Place Armillaria mellea inoculum at the fish-scale-shaped notches of the logs. The inoculum used is a grade III solid inoculum, with a dosage of 0.6kg / m. After placement, cover with soil so that the surface of the cultivation pit has a turtle-back shape. The fungal material is obtained after six months of cultivation.
[0029] It should be noted that during the cultivation process, if there is a rainy day with rainfall exceeding 50 mm within 24 hours, supplement the bacteria 1-2 times as needed according to the supplementation treatment method.
[0030] In addition, the excavation of cultivation pits was carried out in accordance with the Technical Specifications for Gastrodia elata Production (DB41 / T 451-2023).
[0031] S2. In mid-April, dig several planting holes on the selected land. The planting holes should be 100cm long, 60cm wide, and 30cm deep, with a spacing of 50cm between holes. Lay a 3cm layer of humus soil in each planting hole and evenly spray a 100-fold diluted inoculant at a rate of 100ml / m². Then, evenly place the cultivated mycelium in the planting holes. Depending on the size of the mycelium, place 10 seed tubers around it. After placement, cover with loose soil to create a turtle-back shape, and then cover with a 3cm layer of broad-leaved leaves to retain moisture and prevent weeds.
[0032] S3. Choose a cloudy day or evening, and apply the bacteria once each 30 days and 90 days after planting the hemp. Each time, apply 100ml / m of diluted bacteria solution and spray it evenly on the surface of the planting hole. It should be noted that after planting and inoculating the hemp in the spring, the harvest should be carried out in mid-November of the same year on a sunny and rainless day. When harvesting, dig a 30cm deep trench along one end of the ridge, dig layer by layer from shallow to deep, and handle it gently to avoid damaging the surface of the gastrodia.
[0033] The results of two consecutive years of trials in Examples 1 and 2 show that before the application of Enterobacter AV1 inoculant, the average yield per planting hole in a continuously cropped plot (80cm wide, 5m long) was 6.85kg. After the application of Enterobacter AV1 inoculant, the average yield per planting hole in the treated plots (80cm wide, 5m long) in Examples 1 and 2 was 21.44kg, representing a 212.99% increase in yield compared to the continuously cropped plot.
