Planting techniques of Radix Paeoniae Alba

We are very familiar with Radix Paeoniae Alba, which is a common Chinese herbal medicine. At the same time, it blossoms very beautifully, and it is also an ornamental plant. It has the effect of nourishing blood and regulating menstruation, collecting yin and stopping perspiration. It is mainly used for irregular menstruation, night sweats, headache and abdominal pain. It has a long history of cultivation in China, and the planting technology is also relatively mature. The following Xiaobian brings the planting technology of Radix Paeoniae Alba. Let's take a look.

1. Land selection and preparation

Choose the plot with good drainage and ventilation to grow, which requires loose and fertile soil and deep soil layer, preferably corn, wheat or legume crops. The root system of Radix Paeoniae Alba is relatively deep, so deep ploughing should be done in soil preparation, and basic fertilizer should be applied well, requiring deep ploughing of 30-40cm, which can be ploughed and applied into farm manure 3000-400kg. After it is evenly mixed with the soil, it is raked flat to make a bed with a speed of 1.5m to 2.5m. If it is an area with heavy precipitation or poor soil drainage, the border can be about 1 meter wide.

2. Reproduction

Radix Paeoniae Alba has two propagation methods: split-root propagation (bud head propagation) and seed propagation. Root-splitting propagation is chosen to be planted from August to October. If the planting time is too late, the bud head has already sent out new roots, which is easy to be broken during planting. When harvesting the bud head, cut the bud head from the root system, and then select the thick shape, non-hollow, disease-free bud plate, and naturally cut it into several pieces to make seeds. When planting, the hole planting method is adopted, the hole is 3-6cm, the plant row spacing is 50 × 30cm, one or two buds are placed in each hole, manure can be applied when covering the soil, and then the soil is buried into a small pile of steamed bread. Single peony is fruitful, and it can be harvested when the seeds are ripe in August and sowed after harvest. Hole sowing is also used. When sowing, the seed is stirred and sowed with fine soil. The breeding period of seeds is too long. Generally, it takes 2-3 years from sowing to planting, which is less used.

3. Ploughing and weeding

When planting, it is necessary to weed 4-6 times a year to promote plant growth, but pay attention to shallow ploughing, so as not to damage the root system and lead to dead seedlings. At the end of October or early November, when the air temperature drops, the ground temperature also drops, so it is necessary to cut off the branches and leaves above 10cm on the ground, which is beneficial to overwintering.

4. Water and fertilizer management

After applying sufficient base fertilizer, it is generally not to continue topdressing in the second year after planting, three times a year, the first time when the temperature rises from March to April, when the manure can be poured; the second time at the end of April, the same application of fecal and urine fertilizer, 500 kg per mu; the third time before the end of October-November, 200 kg of manure per mu. White is a plant that likes drought and is afraid of waterlogging, so it is generally not necessary to irrigate, only once in severe drought, and timely drainage and waterlogging prevention in rainy season, so as to avoid root rot caused by excessive stagnant water.

5. Harvest

Radix Paeoniae Alba can be harvested after 3-5 years of planting, and the harvest time is from June to September, not too early or too late, early harvest will affect the yield and quality, while too late starch is transformed, too dry, not solid, fragile. When harvesting, choose sunny day, cut off the aboveground rhizome differently, dig out the rhizome, remove the soil, cut off the bud head to make seeds, and the root system is processed for pharmaceuticals.

The above is the planting technology of Radix Paeoniae Alba. I hope it can help you. If you want to know more about the planting of medicinal materials, please follow us.
