Planting technique of Rhizoma acuminata

Lulu alias wild orchid, ghost oil hemp, wolf head flower, is a kind of perennial herb, its root can be used in medicine, it has the effects of heat-clearing and detoxification, detumescence and pus, lower breast and dredging muscles and veins, etc., it is a more commonly used medicine in traditional Chinese medicine. So how to plant the leaky lotus? Let's get to know it.

1. Land selection and preparation

The requirements of the soil are not strict, the general soil can grow, the sandy soil is suitable for cultivation, but the low-lying land and heavy viscous soil should not be planted. Choose a sunny slope to plant, turn the ground 25-30 cm deep, apply rotten farm manure 1500-2000 kg per mu as base fertilizer, spread it evenly on the ground, rake fine and flat, and make a bed 1.2m wide and 20cm high. The length depends on the planting area.

2. Sowing and raising seedlings

When the fruit is ripe in summer every year, the seeds can be harvested and sowed and raised after harvest. First, the seedbed is watered thoroughly, and then the seeds are evenly sown on the bed. In order to improve the germination rate of the seeds, the seeds can be soaked and germinated before sowing. Soak the seeds in warm water for 2-3 days, change the water every time, wrap the seeds in gauze after soaking, put them in an environment of 25-30 degrees to promote germination, rinse the seeds with warm water once a day during germination, and sow seeds until most of the seeds are white. About 7-10 days after sowing, seedlings should be watered at the right time to promote seedling growth.

3. Transplanting

The seedlings grow faster after they are unearthed, and 2-3 true leaves can grow in 10-20 days, then transplant, loosen the soil combined with intermediate ploughing and weeding, then raise seedlings and transplant with them. The transplanting time should be chosen in the evening or cloudy day, using the method of hole planting, one plant per hole, the row spacing of the plant should be 15 × 15 cm, and the two rows should be relatively staggered. After planting, enough water should be watered, and the survival rate is more than 95%. When transplanting, some seedlings should be retained for seedling replenishment, and generally transplanting failures should be timely.

4. Field management

After transplanting, it is necessary to do a good job of weeding by ploughing, loosening the soil, promoting the growth and development of plant roots, and weeding as soon as you see the grass, so as not to affect the growth of the plant. In addition, it is also necessary to do a good job in fertilizer and water management, and timely watering should be done in times of drought. Generally, plants will not blossom in the same year after transplanting, and they will begin to turn green and emerge around the Qingming Festival in the second year. At this time, some fertilizers should be applied to promote early growth. Before flowering, 3-5 kg of potassium dihydrogen phosphate should be applied per mu to improve the flowering and seed setting rate of the plant. Foliar fertilizer spraying can also be used.
