The Latest Techniques and Methods for Cultivating Elecampane (Inula helenium): A Complete Guide
Elecampane (Inula helenium) is a medicinal herb listed in the Pharmacopoeia of the People's Republic of China, and its main medicinal part is its dried root. Elecampane and costus (Aucklandia lappa) are very similar, but their medicinal effects are different. The main effects of elecampane are strengthening the spleen and stomach, relieving pain, and preventing miscarriage, but it also has anti-inflammatory and antibacterial effects. Elecampane has strong adaptability and is suitable for cultivation in various parts of our country, but it is mainly distributed in Zhejiang, Henan, and other places in our country. Now, let the editor introduce the artificial cultivation techniques of elecampane to everyone.
1. Site Selection and Land Preparation
Elecampane has the characteristics of preferring sunlight and moisture, tolerating waterlogging, not tolerating drought, and tolerating cold. Its cold resistance is quite good; generally, it can still grow normally at minus fifteen degrees. Because elecampane has strong adaptability to the growing environment, it can be planted in ordinary soil. However, when choosing a planting site, we still have some considerations, such as the terrain of the planting site, drainage, permeability, water source and irrigation conditions, and soil fertility. When there is a choice of planting sites, naturally we should choose the one with better conditions. Land preparation should be combined with the application of base fertilizer. Generally, three to four tons of farmyard manure are needed per mu, so the fertilizer requirement is very large. Finally, level the land, make ditches and ridges; a ridge width of fifty cm, a height of forty cm, and a ditch width of twenty cm will do.
2. Planting Methods
There are generally two methods for planting elecampane. The first is seed propagation, using the drill sowing method. Seed propagation is generally carried out from the end of March to early April each spring, and then shallow furrows about three cm deep and ten cm wide are opened in rows with a row spacing of thirty cm; then the seeds are evenly scattered, covered with soil, and the seeds are concealed; finally, water once. After the seedlings grow to about thirty cm, transplant and set them in place. The second is root division cultivation, generally before early spring sprouting, dig out the underground rhizomes of elecampane; then distinguish them according to different thicknesses; then plant and set them in place with a row spacing of forty cm and a plant spacing of thirty cm; finally, water them.
3. Field Management
After elecampane is set in place, we should observe the growth of elecampane in the field. If dead seedlings or missing seedlings are found, replant them in time to ensure a full stand of seedlings in the field. One point to note when replanting seedlings is not to replant at noon on very sunny days; generally, choose cloudy and rainy days, or morning or evening, for planting. Next, pay attention to keeping the soil moist and not allowing drought to occur. Generally, water once about every three days. When the base fertilizer is sufficient, generally only one topdressing is needed, mainly cake fertilizer and manure and urine water. But if elecampane grows poorly, multiple fertilizations are still needed. Finally, during the growth process of elecampane, the flower stems of elecampane also need to be cut off, unless seeds are to be kept.
4. Disease and Pest Control
Elecampane has relatively strong disease resistance. When field management is done well, there are basically no diseases or pests. But sometimes leaf spot disease, aphids, stem borers, moth pests, and others also appear, so we should also be prepared for disease and pest control. However, when using pesticides, pay attention to the use concentration of the pesticide to avoid excessive pesticide residues, otherwise the losses in cultivation will be very large.
The above is what the editor wants to introduce to everyone today about the artificial cultivation techniques of elecampane. After reading the above, I wonder how much everyone knows about elecampane cultivation? Are there still any unclear points? If so, you can leave a message below for consultation.
