Cultivation Techniques and Key Field Management Points for Bistort
Bistort, also known as Caoheche or Quanliao, is a perennial plant of the Polygonaceae family. Wild bistort generally grows on hillside grasslands and has the effects of clearing heat, calming convulsions, regulating dampness and reducing swelling. It is used to treat febrile diseases, tetanus and other conditions. So, do you know how to grow bistort? Today, the editor brings you an introduction to bistort cultivation techniques. Interested friends can read the following content carefully.
1. Site Selection and Land Preparation
Bistort is characterized by preferring cool conditions, tolerating cold and resisting drought, which also shows that it does not have high requirements for the growing environment. However, it is best to choose a plot with fertile, loose soil and good drainage and permeability. When preparing the land, we should carry out deep plowing together with base fertilizer, with a depth of about 25 cm. Finally, break up the soil clods finely, open furrows and make beds, and rake the bed surface level before planting.
2. Planting Methods
Bistort can be planted using seed propagation techniques or root division propagation techniques. Seed propagation is generally carried out around early April each spring, using the drill sowing method, sowing the seeds evenly in the furrows, with a distance of about 35 to 45 cm between each row, and finally covering with soil to conceal the seeds. Root division propagation is carried out in autumn or spring. Dig out part of the bistort tubers, then select robust rhizomes with well-developed root systems for planting. When planting, the row spacing is 35 to 45 cm, and the plant spacing is 35 cm. Cover with soil and press firm, then wait for seedlings to emerge.
3. Field Management
If seed propagation is used, we need to thin and fill in seedlings when the young seedlings grow to about 5 to 6 cm, ensuring a plant spacing of about 30 to 35 cm. Next, watering and drainage should be carried out reasonably according to the growth stage of bistort and the climate conditions at the time. Under normal circumstances, water once about every 15 days. Next, carry out intertillage and weeding reasonably, about 3 to 4 times a year. In order to avoid damaging the root system of bistort, shallow cultivation is usually carried out. This can not only promote nutrient absorption, but also improve soil permeability. In addition, it is best to provide shade and build supports, which can avoid damage to bistort from light and reduce the harm of pests and diseases. At the same time, we can also use straw, leaves and other mulch, which can improve soil structure and promote the growth of bistort. Finally, in order to avoid nutrient loss, pruning can also be carried out, which can also help improve its medicinal properties.
4. Production Area Distribution
The production areas of bistort are actually quite widespread. Bistort exists in many regions of China, and at present, artificially cultivated bistort is grown in many areas. For example, it is planted in Northeast China, North China, Shaanxi, Hubei, Shandong, Henan, Hunan and other places. In addition, bistort is also cultivated in many areas abroad, such as Japan, Russia, Kazakhstan and so on.
The above is a brief introduction to bistort cultivation techniques brought to you by the editor. If you are interested, you can read the following carefully. In fact, growing bistort is also very simple, but it is also a Chinese medicinal herb that is currently in very short supply on the market, and it also has certain prospects for cultivation, so you may still consider it.
