Detailed Explanation of Strychnos nux-vomica Planting Methods and Technical Key Points
Strychnos nux-vomica is also called the strychnine tree, nux-vomica, and maqian tree, among other names. It is a dicotyledonous tree of the genus Strychnos. Strychnos nux-vomica is also a traditional Chinese medicinal herb, but if one does not understand medical principles, it can cause poisoning. Its seeds are extremely toxic, but after processing they can be used as medicine, and can be used to strengthen the stomach, unblock collaterals and dissipate nodules, reduce swelling and relieve pain. So how is Strychnos nux-vomica planted? Below is what the editor wants to share with you today. Let's take a look.
1. Site selection and land preparation
Strychnos nux-vomica has the characteristics of preferring warmth and moisture, but being intolerant of cold and drought. So when we choose a planting site, we can select it according to these characteristics. Generally, planting should be done in alluvial soil by rivers or in loess and red soil in hilly areas. The soil should be slightly acidic or slightly alkaline, rich in humus, and well-aerated sandy loam or clay loam. Before planting, carry out land preparation, but generally by the method of pit cultivation, with pits 50 cm long, 50 cm wide, and 40 cm high. After the soil weathers, apply base fertilizer and then wait for planting.
2. Propagation methods
There are two propagation methods for Strychnos nux-vomica: seed propagation and bud grafting propagation. For seed propagation, the seeds need to be soaked before sowing, then taken out two days later for germination. When the radicle of the seed produces a white sprout point, sowing can begin. For bud grafting propagation, it is necessary to select good rootstock and bud sticks. The rootstock should be selected for developed roots, robustness, freedom from pests and diseases, and strong adaptability; the bud sticks should be selected for high yield and plumpness, and then grafting is carried out according to nursery stock grafting techniques.
3. Field management
After sowing or grafting, Strychnos nux-vomica generally emerges and survives in about twenty days at most. In winter, however, it takes more than a month. When the seedlings grow to about 60 cm, we can transplant and establish them. Dig out the seedlings and transplant them into the prepared field for planting. After planting, we must maintain field moisture and water frequently. At the same time, we should also water frequently to prevent the soil from becoming compacted and affecting soil aeration. Second, after the seedlings have grown for two months, we should reasonably apply an appropriate amount of manure and urine water or urea as a topdressing, and then wait until the second half of the year for another topdressing, mainly with nitrogen fertilizer and phosphorus fertilizer. Finally, we should scientifically prune branches and leaves and shape the plant, thinning out overly dense branches and leaves, cutting off dead branches, old branches, and diseased branches, and cultivating the main trunk and reserve trunk.
4. Pest and disease control
The main disease of Strychnos nux-vomica is leaf spot disease. This disease mainly harms the leaves of Strychnos nux-vomica and affects its growth. We can usually use Bordeaux mixture or thiophanate-methyl for control, spraying once about every ten days, and spraying continuously two to three times. The most common pests are noctuid moths, sphinx moths, and weevils. These pests mainly harm the tender leaves of Strychnos nux-vomica, and the peak period of these pests is during the flowering period, so preventive preparations should be made in advance, and trichlorfon should be used for control.
Many of us may not know much about Strychnos nux-vomica, but it is indeed a relatively important medicinal material in our lives, and some people have used it in life. The planting methods for Strychnos nux-vomica introduced by the editor today are hoped to be helpful to all partners planting Strychnos nux-vomica, and also hoped that more people can recognize and understand Strychnos nux-vomica.
