Bistort Cultivation Techniques
1. Site Selection and Land Preparation
Bistort has characteristics such as preferring cool conditions, tolerating cold, and resisting drought, which also shows that it does not have high requirements for the growing environment. Although bistort has low requirements for the growing environment, when choosing soil it is still more suitable to pick one with good drainage. It is recommended to carry out deep ploughing together with base fertilizer, with a deep ploughing 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
Generally, bistort is now grown by seed propagation or root division propagation. Seed propagation is used more often. Starting each spring, growers successively adopt the drill sowing method, evenly scattering the seeds into the furrows, with the distance between each row at about 35 to 45 cm, and finally covering with soil to hide the seeds. For root division propagation, besides spring, autumn can also be chosen. First dig out the tubers of bistort and select the relatively firm and robust ones; such rhizomes can be used for planting. When planting, the row spacing is 35 to 45 cm and the plant spacing is 35 cm. Cover with soil and firm it down, then wait for seedlings to emerge.
3. Field Management
If seed propagation is used, we need to thin and fill in seedlings once the young plants have grown to about 5 to 6 cm, ensuring the plant spacing is kept at about 30 to 35 cm. Next, watering 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 about once every 15 days. Everyone should know that field management also includes the step of weeding. For bistort, weeding can be done about 3 to 4 times a year, not too many, to avoid harming the root system of bistort. Finally, we can carry out appropriate shading work, and building supports is a very good choice. Reducing long periods of direct sunlight is quite helpful for the growth of bistort. At the same time, we can also use straw, leaves, and so on as mulch, which can improve the soil structure and promote the growth of bistort. Finally, in order to avoid nutrients being lost, pruning can also be carried out, which can also play a role in improving medicinal properties.
