The Latest Detailed Tutorial on Cultivation Techniques for Rhaponticum uniflorum
Rhaponticum uniflorum, also known as wild orchid, ghost oil hemp, and wolftooth flower, is a perennial herbaceous plant whose roots can be used as medicine, with effects such as clearing heat and detoxifying, reducing swelling and discharging pus, promoting lactation and unblocking meridians, and is a relatively commonly used medicinal material in traditional Chinese medicine. So how should Rhaponticum uniflorum be cultivated? Let's find out together.
1. Site selection and land preparation
Rhaponticum uniflorum has low requirements for soil and can grow in general soil, but sandy soil is suitable for cultivation, while low-lying land and heavy clay soil are not suitable for planting. Choose a sunny slope for planting, plow the ground deeply 25-30 cm, apply 1500-2000 kg of decomposed farmyard manure per mu as base fertilizer, spread it evenly on the ground, rake it fine and level it, and make beds 1.2 m wide and 20 cm high, with the length depending on the planting area.
2. Sowing and seedling raising
The fruit matures every summer, and at this time the seeds can be harvested, and after harvesting they can be sown for seedling raising. First water the seedbed thoroughly, then evenly broadcast the seeds on the bed surface. In order to improve the seed germination rate, the seeds can be soaked and pregerminated before sowing. First soak the seeds in warm water for 2-3 days, changing the water each time, then wrap the soaked seeds in gauze and place them in an environment of 25-30 degrees for pregermination. During pregermination, rinse with warm water once a day until most seeds show white and can be sown. After sowing, seedlings emerge in about 7-10 days, and at this time water should be applied in a timely manner to promote seedling growth.
3. Transplanting
After the seedlings emerge, they grow relatively quickly. Generally, after 10-20 days, when 2-3 true leaves have grown, transplanting can be carried out. Loosen the soil in combination with intertillage and weeding, then lift the seedlings for transplanting, transplanting as they are lifted. It is best to choose the evening or a cloudy day for transplanting, using the hole planting method, planting one plant per hole, controlling the plant and row spacing at 15×15 cm, with two rows planted in a relatively staggered manner. After planting, water thoroughly, and the survival rate can reach more than 95%. When transplanting, some seedlings should be kept for replanting, and generally failed transplants should be replanted in a timely manner.
4. Field management
After transplanting, do a good job of intertillage and weeding, loosen the soil, and promote the growth and development of the plant root system. Remove weeds as soon as they appear, so as to prevent weeds from affecting plant growth. In addition, do a good job of fertilizer and water management. Water in a timely manner during drought. Generally, plants transplanted in the same year will not bloom, and in the second year around Qingming they begin to turn green and emerge. At this time, apply some fertilizer to promote early growth. Before flowering, broadcast 3-5 kg of potassium dihydrogen phosphate per mu to increase the flowering and fruiting rate of the plants, and foliar fertilizer spraying can also be used.
