The Latest Cultivation Techniques for Cimicifuga: How to Effectively Increase Yield
Cimicifuga (black cohosh) is a medicinal herb used to treat headache with chills and fever, sore throat, mouth sores, gynecological diseases, and chronic diarrhea and dysentery. In fact, its main effects are to release the exterior and promote eruption of rashes, clear heat and detoxify, and raise yang and lift prolapse. Although it has many effects and uses, people with weak spleen and stomach should still not use it casually. At present, Cimicifuga is mainly cultivated in Liaoning, Hebei, Shaanxi and other places in China, but the yield from cultivation is not satisfactory. So how can we increase the yield of Cimicifuga? Let's take a look at the solutions below.
1. Soil requirements
If you want a high yield of Cimicifuga, the choice of planting site is the most basic condition. In fact, most soils can be used to grow Cimicifuga, but the best planting site should be a plot with relatively deep soil layers, sufficient water resources, convenient drainage and irrigation, uncontaminated soil, fertile soil, loose soil texture, and a sunny aspect. When preparing the land, use the large-ridge high-bed technique, apply sufficient farmyard manure, and reasonably plan the row spacing in the soil.
2. Sowing methods
Sowing methods mainly include two aspects: sowing time and sowing method. The correct sowing method inevitably affects the yield of Cimicifuga. The best sowing time is from the end of April to mid-May and from mid-October to early November each spring. Sowing during these two periods gives a higher emergence rate for Cimicifuga and also a higher survival rate after planting. The sowing method is generally drilling, with a row spacing of about 25 cm. Then scatter the seeds evenly in shallow furrows, cover with fine soil, water once, and finally cover with a layer of straw or plastic film to keep warm. If transplanting is to be carried out, generally wait until the seedlings have grown for one year, then plant them at a row spacing of 50 cm and a plant spacing of 40 cm.
3. Water and fertilizer management
During the growth of Cimicifuga, we need to carry out scientific fertilization and reasonable watering, and its water and fertilizer management is the key to determining a high yield. Generally, it is best to apply additional fertilizer three to four times a year. Carry out the first additional fertilization in June and July, mainly with nitrogen fertilizer, and combine it with intertillage. Next, at different growth stages of Cimicifuga, scientifically use fertilizer types and amounts according to its fertilizer requirements. If a dry season occurs, water in time to maintain soil moisture, but if there is continuous rainfall, remember to drain excess water to avoid root rot.
4. Weeding and removing flower buds
During the growth of Cimicifuga seedlings, we should frequently carry out intertillage and weeding. This can improve soil permeability, promote root growth, and also prevent nutrients from being consumed by weeds. In the later growth process, intertillage is relatively infrequent, but when necessary, loosening the soil and earthing up are still needed to prevent the soil from becoming compacted and affecting the yield of Cimicifuga. To increase the yield of Cimicifuga, when it produces flower buds, we need to remove the buds. Except for Cimicifuga used for seed production, all the rest need to be cut off. This allows nutrients to be supplied in a concentrated way and promotes the growth of rhizomes.
The above are actually some of the issues that need attention in the process of growing Cimicifuga, and they are also relatively key issues in cultivation techniques. I hope the above can help more people in need. At the same time, I also wish everyone in the new year another breakthrough in Cimicifuga cultivation yield and higher economic benefits.
