Description

Technical Field

[0001] The invention relates to the field of cultivation technology, in particular to a cultivation method of Atractylodes macrocephala in mountainous areas. Background Art

[0002] Atractylodes macrocephala, a medicinal plant, belongs to the genus Atractylodes in the Asteraceae family. It is produced in Zhejiang, Jiangsu, Jiangxi, Henan, Anhui, Sichuan, Hunan, Henan, Fujian and other provinces in China, and is now distributed in Japan. As an important medicinal plant, Atractylodes macrocephala is mainly used to eliminate edema, enhance human immunity and other aspects. The rhizome of Atractylodes macrocephala is dried and ground, and then powdered and used to make traditional Chinese medicine. The rhizome of Atractylodes macrocephala contains a large amount of rich volatile oil, which mainly includes atractylodesin, atractylol, atractylodes lactone A, atractylodes lactone B, etc. These ingredients make Atractylodes macrocephala have a certain diuretic effect and the effect of lowering blood sugar.

[0003] Currently, the demand for Atractylodes macrocephala is increasing, but due to the economic development trends in Zhejiang and other regions, the area where Atractylodes macrocephala is cultivated is shrinking, resulting in an uncoordinated production and sales relationship between Atractylodes macrocephala and an increasingly obvious shortage of high-quality Atractylodes macrocephala. Furthermore, Atractylodes macrocephala has a strong barrier to continuous cropping. Continuous planting of Atractylodes macrocephala in the same region and on the same plot for many years can lead to problems such as degradation of the Atractylodes macrocephala resource and a decline in quality. The present invention provides a cultivation method to address the problem of low Atractylodes macrocephala yield.

[0004] At present, there are mainly the following methods for planting Atractylodes: 1. Stratification of Atractylodes seeds to break the dormancy of Atractylodes seeds before planting; 2. Grafting of Atractylodes; 3. Planting of Atractylodes by cuttings; 4. Planting of Atractylodes by layering.

[0005] However, existing planting methods have the following drawbacks: 1. Stratification is time-consuming, typically three to five months. 2. The grafting process is cumbersome, requiring the selection of plants with similar growth morphology. Furthermore, it does not address the low germination rate of Atractylodes macrocephala. 3. The nutrients required for growth are not replenished in a timely manner during the planting process, resulting in slow growth. 4. High levels of pesticides are used during the planting process, causing some damage to land resources.

[0006] This method involves budding and cultivating Atractylodes macrocephala seeds without the use of pesticides. The soil and irrigation levels are regulated, and human intervention in bud growth occurs during the growth process. This reduces the 27% loss associated with the original method and reduces the mortality rate of Atractylodes macrocephala by 36%. The seeds are treated with plant ash and stirred to coat the surface. This method utilizes ecological cultivation techniques to minimize pollution to land resources. Summary of the Invention

[0007] The purpose of the present invention is to provide a cultivation method of Atractylodes macrocephala in mountainous areas to overcome the deficiencies in the prior art.

Sowing the Atractylodes macrocephala seeds covered with plant ash; using a mixture of black soil, sandy loam and humus soil as the sowing soil; S5. Prune the roots of Atractylodes macrocephala when they grow to 20-23 cm. Prune the roots to 5-10 cm below the ground. After pruning, bury them in the soil.

[0009] Preferably, step S1 specifically includes the following operations: S11. During the seed ripening period on sunny days in mid-to-late November, select rhizomes of Atractylodes macrocephala that are greater than 50 cm tall, free of pests and diseases, with full, oval leaves, and 5-8 cm long. Dig out and cut off the underground rhizomes, and bring the above-ground rhizomes back for Atractylodes macrocephala seed collection. S12, placing the above-ground rhizome part in an oven and drying it at a constant temperature of 45-55 degrees Celsius, then threshing, removing the fluff and shriveled seeds, and selecting Atractylodes macrocephala seeds with full seeds and a length of 28-30 mm; S13, soak the Atractylodes macrocephala seeds in 450~550mg·L -1 Soak the seeds in the phenylamino acid solution for 1 to 2 hours, then take them out and soak them in cold water at 5 to 10 degrees Celsius for 12 to 13 hours. After completion, dry the Atractylodes macrocephala seeds in a naturally ventilated place for 3 to 4 hours to complete the pretreatment.

[0010] Preferably, step S2 specifically includes the following operations: sterilizing the pretreated Atractylodes macrocephala seeds in a carbendazim solution with a carbendazim to water ratio of 1:4000 to 1:5500; then sterilizing the seeds in an environment with a relative humidity of 45% to 55% and a temperature of 30 to 35°C, using a power of 25 to 30W and an irradiation intensity of 80 to 100 μW·(cm 2 ) -1 The seeds are irradiated with ultraviolet light to complete the light treatment of Atractylodes macrocephala seeds.

[0013] Beneficial effects of the present invention: 1. The present invention uses 450~550mg·L of Atractylodes macrocephala seeds -1 Soaking the seeds in a solution of phenylamine acid can awaken the dormancy of Atractylodes macrocephala seeds and effectively increase the germination rate of Atractylodes macrocephala seeds. 2. The present invention uses a 1:4000 to 1:5500 carbendazim solution for seed sterilization, which can initially avoid the probability of diseases and pests during the growth process; 3. The present invention uses plant ash to cover the sowing after removing the seed shell of Atractylodes macrocephala. The plant ash can act as an antibacterial agent during the growth of Atractylodes macrocephala, which can effectively reduce the possibility of Atractylodes macrocephala encountering white rot and iron leaf disease during the growth process. 4. The present invention selects a soil ratio of black soil, sandy loam and humus soil of 2:6:2 to 1.5:7:1.5, which maximizes the soil's own fertility and better provides natural nutrition for the growth of Atractylodes macrocephala; 5. The present invention improves the fertility of the soil itself by adding 2% to 3% by weight of double superphosphate or superphosphate, 4% to 5.5% by weight of fish bone powder or lime nitrogen, and 4% to 6% by weight of sugar alcohol magnesium, thereby providing the calcium, phosphorus, and magnesium elements required for the growth of Atractylodes macrocephala. 6.
