How to grow Striga asiatica? A detailed guide to the latest cultivation methods
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 Striga asiatica should be grown. The editor has given the following answer to this question, so let us take a look together.
1. Soil and fertilizer management
Striga asiatica is a semi-parasitic plant, so its requirements for soil and fertilizer are relatively high. Striga asiatica needs to rely on other plants in order to carry out photosynthesis, as well as to survive and grow, so the planting site generally must be chosen with soil that both suits the survival of Striga asiatica and also meets the growth needs of the host plant. Natural grassland can be used to grow Striga asiatica, and there is no need for excessive land preparation; it is enough to spread a layer of fine soil and sufficient base fertilizer on the grassland before sowing.
2. Sowing at the right time
Striga asiatica is generally propagated by sowing, and the sowing time is from the end of March to the beginning of 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 conditions, seedlings will emerge in about ten days.
3. Transplanting seedlings and setting them in place
Striga asiatica seedlings grow relatively slowly, so the seedling cultivation period is relatively long, but during the seedling stage no special management is needed; it is only necessary to reasonably control the intake of water and nutrients. When the seedlings have grown to about 6 to 8 cm, they can be transplanted and set in place. 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, replant them in time to ensure a full stand of seedlings in the field. After the seedlings have survived planting, loosen the soil in time and clear away excess weeds from the field, so as to prevent nutrients from being absorbed by the excess weeds and affecting the nutrient supply. In dry weather, water appropriately to prevent the grassland from drying out and affecting the growth of Striga asiatica. Finally, apply a topdressing of fertilizer once to each plant to promote plant growth, increase yield and improve quality, thereby obtaining high profits.
The above is the artificial cultivation method for Striga asiatica that the editor introduced to you today. Because the artificial cultivation technology for Striga asiatica is not yet complete, the yield of cultivated Striga asiatica is also not particularly ideal, and this is an important reason why the market price of Striga asiatica remains high.
