How to grow peony bark

Cortex moutan, also known as Cortex moutan, is a kind of medicinal material used for clearing heat and cooling blood, promoting blood circulation and removing blood stasis and relieving deficiency fever. it is mainly taken from the dry root bark of Ranunculaceae plant Paeonia suffruticosa. At present, the planting of moutan bark is distributed in Anhui, Sichuan, Henan and Shandong. It has a certain curative effect on warm toxic hair spots, hematemesis, night fever and early cold, amenorrhea, dysmenorrhea and other symptoms. So how to plant moutan bark? Let's study with the editor today.

1. Daejeon dressing and finishing

Peony bark has the characteristics of being warm, moist, drought-resistant, cold-resistant, not waterlogging-resistant, afraid of stagnant water, afraid of high temperature and avoiding strong light. The planting land is generally chosen in the sandy loam with dry, easy drainage, easy irrigation, deep soil layer, loose soil and fertile soil. The planting land had better have a certain slope, the groundwater level is low, be careful not to plant in saline-alkali soil and heavy clay. Before planting, deeply plough the soil and apply sufficient base fertilizer, which is mainly circle fertilizer and cake fertilizer. Flat and fine, and then open a ditch to make a border, the width of the border is about 40 to 50 centimeters, and the depth of the ditch is about 30 centimeters.

2. Methods of reproduction

There are four ways of propagation of peony bark, which are seed propagation, ramet propagation, grafting propagation and cutting propagation. Seed propagation is mainly used in Fengdan, Anhui Province, which needs to raise seedlings before transplanting, and the sowing time is from late July to early October. At the same time, soak the seeds in warm water before sowing, and finally sow them in strips. The propagation method of ramet and grafting is mainly adopted in Heze, Shandong Province, and the ramet is usually carried out after the Autumn Equinox. The sturdy and pest-free plants are trimmed and planted, and the spacing between rows and plants is 35 cm and 25 cm. Grafting can be planted between White Dew and the Autumn Equinox, according to plant and row spacing of 15 or 50 cm. Finally, the way of cutting is the most used in Hunan and Hubei, and the time of planting is the same as that of grafting, and the distance between plants and rows is 20 or 50 cm.

3. Field management

There is no need for management for the whole winter after planting, and the first weeding and soil loosening and shallow ploughing can be carried out until the next year when the insects are stung. After the Spring Equinox, the soil was cultivated to protect the growth of the seedlings, while the second time of weeding and loosening the soil was carried out before and after Ching Ming Festival. It is necessary to weed and loosen the soil nine or ten times a year, and loosen the soil after rainfall or watering to prevent the land from solidifying. After planting, topdressing is not needed until the next year, and then topdressing can be applied twice a year, which is divided into spring fertilizer and autumn fertilizer. Spring fertilizer is mainly soil fertilizer or dung, combined with cake fertilizer, autumn fertilizer is the same as spring fertilizer, but the amount is twice as much as spring fertilizer. In general, you don't need watering, but if the weather is dry, you still need an appropriate amount of watering, but you must remember to drain water in a timely manner.

4. Pruning and picking flowers

In the second year after planting, we should arrange and prune some uneven branches, and then erase the newly germinated buds reasonably according to the growth of the plant, and ensure the uniformity of the branches. It should also be noted that in order to increase the yield of peony bark, what to do is to remove the buds to concentrate nutrients on the roots and promote the growth of the roots, except for the remaining seeds or ornamental plants.

5. Disease prevention and control

The main diseases and insect pests of peony bark are blight, leaf spot, root rot, peony rust and core worms. Then we can use carbendazim, Bordeaux liquid, chlorothalonil, sodium dipterex and trichlorfon respectively. Of course, we can also strengthen the intensity of field management to achieve the effect of disease prevention.

The above is what the editor wants to tell you today, the planting technology of moutan bark, if you encounter other problems in the process of planting, you can also leave a message for consultation and discussion.
