Detailed Explanation of the Planting Methods and Techniques for Striga asiatica
Striga asiatica is an annual herbaceous plant and also a semi-parasitic plant belonging to the Scrophulariaceae family, and the whole plant can be used as medicine. The main producing areas of Striga asiatica in China are Yunnan, Guizhou, Guangxi, Hunan, and Fujian, among other places. However, there is currently no large-scale cultivation, and the artificial cultivation techniques are not yet mature. Recently, a friend asked how to grow Striga asiatica. In response to this question, the editor has provided the following answer. Let's take a look together.
1. Soil and Fertilizer Management
Since Striga asiatica is a semi-parasitic plant, its requirements for soil and fertilizer are relatively high. Striga asiatica needs to rely on other plants to carry out photosynthesis, as well as to survive and grow, so the planting site should generally be chosen with soil that both suits the survival of Striga asiatica and meets the growth needs of parasitic plants. Natural grassland can be used for planting Striga asiatica, and there is no need for excessive land preparation. It is only necessary to spread a layer of fine soil and sufficient base fertilizer on the grassland before sowing.
2. Timely Sowing
Striga asiatica is generally propagated by sowing, and the sowing time is from the end of March to early April each year. On the selected planting site, evenly scatter the seeds of Striga asiatica on the fine soil, then cover with another layer of fine soil, and adjust the temperature of the planting site to around 18 degrees. Under normal circumstances, seedlings will emerge in about ten days.
3. Transplanting and Establishing the Seedlings
The seedlings of Striga asiatica grow relatively slowly, so the seedling cultivation period is relatively long, but during the seedling stage no specialized management is needed; it is only necessary to reasonably control the intake of water and nutrients. When the seedlings grow to about 6 to 8 cm, they can be transplanted and established. The planting density is 30 cm between rows and 25 cm between plants.
4. Field Management
About 5 to 7 days after planting, observe the growth of Striga asiatica in the field to see whether any plants have died. If so, timely replanting is needed to ensure a full stand of seedlings in the field. After the seedlings survive transplantation, loosen the soil in a timely manner and remove excess weeds from the field to prevent nutrients from being absorbed by the excess weeds and affecting nutrient supply. During dry weather, appropriate watering is needed to prevent the grassland from drying out and affecting the growth of Striga asiatica. Finally, each plant needs one topdressing of fertilizer to promote plant growth, increase yield, and improve quality, thereby obtaining high profits.
The above is the artificial cultivation method for Striga asiatica introduced by the editor today. Because the artificial cultivation technology for Striga asiatica is not yet perfect, the yield of cultivated Striga asiatica is not particularly ideal, which is also an important reason why the market price of Striga asiatica remains high.
