Detailed Explanation of the Key Cultivation Techniques for Datura
Datura is a plant in the Solanaceae family under the angiosperms, and it is a very beautiful flower. Wild varieties can be seen in many parts of our country. Datura not only has ornamental value, but is also one of the main raw materials for making anesthetics. Moreover, the leaves, flowers and seeds of the Datura plant can all be used as medicine, with effects such as relieving asthma and stopping pain, and dispelling cold and detoxifying. So how should Datura be cultivated? Below, the editor brings you the cultivation techniques for Datura. Let's take a look together!
1. Site selection and land preparation
Datura is suitable for planting in soil that is sheltered from the wind and faces the sun, with sufficient fertility, loose and deep texture, and good drainage and irrigation. Before sowing, pay attention to whether there are residual herbicides or pathogens present. Land preparation should be carried out in a timely manner. Before winter arrives, deep plowing and medium tillage should be done, with a depth of no less than 30cm. Disinfection work should be done well to prevent harmful substances remaining in the soil from affecting the growth of Datura. Land preparation should be carried out together with fertilization, applying sufficient base fertilizer, with the base fertilizer mainly being decomposed farmyard manure. After fertilizing, rake the soil level. In the spring of the second year, prepare the land again and make field beds to facilitate management and harvesting after sowing.
2. Sowing and seedling raising
After preparing the land, sow at the appropriate time around the Beginning of Spring. Select plump seeds with no obvious wounds, and first do a good job of seed soaking, germination promotion and disinfection. Then control the planting density well and dig the planting holes, with a planting spacing of about 60 cm * 45 cm. The planting holes should not be too deep; about 3-4 cm is sufficient. Because Datura seeds are relatively small and have weak ability to push through the soil, those planted too deep are difficult to emerge, and the growth ability after emergence will also decline noticeably. Sow 5 seeds in each planting hole, cover with fine soil, and press down to preserve soil moisture. If raising seedlings, the best transplanting time is around the end of May.
3. Field management
After successful final singling of seedlings, when the seedlings grow to about 9 cm, thin them in a timely manner, removing seedlings that are too weak, affected by pests or diseases, or dead. The number of seedlings in each planting hole must not exceed 2 plants. Then, when the seedlings are about 16 cm tall, thin them again, increasing the number of seedlings in the planting holes to about 4 plants. After final singling, topdressing should be carried out immediately. In the middle and late stages of growth, do a good job of water and fertilizer management according to the plant growth condition. During the growth of Datura, medium tillage and weeding should also be done well, with no fewer than 2 times, and soil should be properly banked up to prevent the plants from lodging.
4. Pest and disease control
Datura does not have very strong disease resistance, and some pests and diseases often harm the growth of Datura. Common pests and diseases of Datura include black spot, aphids, ladybugs, and so on. We should avoid the occurrence of pests and diseases, because once pests and diseases occur, the growth of Datura will definitely be affected, causing some unnecessary losses. Strengthen field management, reduce the presence of pathogens, and lower the incidence of disease. Also prepare control agents for various common pests and diseases to avoid sudden outbreaks.
The above is a brief introduction to Datura cultivation techniques. What we need to note is that Datura is toxic, and its toxicity is relatively strong, so it must never be eaten raw. After accidental ingestion, poisoning symptoms will appear within 20 minutes to 30 minutes, such as drowsiness, convulsions, and so on, and in severe cases it will lead to death. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
