Latest Cultivation Techniques and Methods Tutorial for Bistort
Bistort is also called Caoheche and Quanliao. It is a perennial herbaceous plant of the Polygonaceae family. Wild bistort generally grows on hillside grasslands and has the effects of clearing heat and calming fright, and resolving dampness and reducing swelling. It is used to treat febrile diseases, tetanus and other diseases. So do you understand the planting methods of bistort? Today the editor brings you an introduction to the cultivation techniques of bistort. Friends who are interested can read the following content carefully.
1. Site selection and land preparation
Bistort has the characteristics of preferring cool conditions, tolerating cold, and resisting drought, which also shows that bistort 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 ploughing together with base fertilizer, and a deep ploughing depth of about 25 cm is sufficient. Finally, break the soil clods finely, open furrows and make beds, and rake the bed surface level before planting.
2. Planting methods
Bistort planting can use seed propagation techniques and can also use root division propagation techniques. Seed propagation is generally carried out around early April each spring, using the drill sowing method, spreading the seeds evenly in the furrows, with the distance between each row at about 35 to 45 cm, and finally covering with soil to hide 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 firmly, then wait for emergence.
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, and the plant spacing should be kept at about 30 to 35 cm. Next, irrigation and drainage should be carried out reasonably according to the growth stage of bistort and the climatic conditions at the time. Under normal circumstances, water once about every 15 days. Next, intertillage and weeding should be carried out reasonably, about 3 to 4 times a year. In order to avoid damaging the root system of bistort, shallow tillage is usually carried out. This can not only promote the absorption of nutrients but also improve soil aeration. In addition, it is best to provide shading and set up 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 coverings, which can improve the soil structure and promote the growth of bistort. Finally, in order to avoid nutrient loss, pruning can also be carried out, which can also play a role in improving medicinal properties.
4. Production area distribution
The distribution of bistort production areas is actually relatively broad. Bistort exists in many regions of our country, and at present many regions have artificially planted bistort. For example, it is planted in Northeast China, North China, Shaanxi, Hubei, Shandong, Henan, Hunan and other places. In addition, many regions abroad also cultivate bistort, 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, bistort planting is also very simple, but it is also a Chinese medicinal material that is currently in very short supply on the market, and it also has certain planting prospects, so you can still consider it.
