Cultivation and Management Methods to Increase the Yield of Cimicifuga
Cimicifuga is a Chinese 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 releasing the exterior and promoting eruption, clearing heat and detoxifying, and raising yang and lifting prolapse. Although it has many effects and functions, people with weak spleen and stomach should still not use it casually. At present, cimicifuga is mainly grown in Liaoning, Hebei, Shaanxi and other places in our country, but the planting yield is not satisfactory. So how do 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, sufficient water resources, convenient drainage and irrigation, pollution-free soil, fertile soil, loose soil texture, and facing the sun. When preparing the land, use the large-ridge and 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 in these two periods gives a higher seedling emergence rate for cimicifuga, and at the same time a higher survival rate after planting. The sowing method is generally drilling, with a row spacing of about 25 cm, then evenly scatter the seeds in shallow furrows, cover with fine soil, water once, and finally cover with a layer of rice 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 process 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 speaking, it is best to apply topdressing three to four times a year. The first topdressing is carried out in June and July, mainly with nitrogen fertilizer, and combined with intertillage. Second, at different growth stages of cimicifuga, scientifically use fertilizer types and amounts according to its fertilizer requirements. If a dry season occurs, water promptly to maintain soil moisture, but if there is continuous rainfall, remember to drain excess water to avoid root rot.
4. Weeding and bud removal
During the growth of cimicifuga seedlings, we should frequently carry out intertillage and weeding. This can improve soil permeability, promote root growth, and at the same time 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 land from becoming compacted and affecting the yield of cimicifuga. In order to increase the yield of cimicifuga, when cimicifuga produces flower buds, we need to remove the flower buds. Except for cimicifuga used for seed production, all the rest need to be cut off, so that nutrients can be supplied in a concentrated way and the growth of the rhizome can be promoted.
The above are actually some of the issues that need attention in the process of planting 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 that in the new year, the yield of cimicifuga planting can break through once again and obtain higher economic benefits.
