1. Maintenance methods1. Temperature: During the entire growth period, the most suitable temperature is 19 to 25 degrees, which can be maintained within this range. If it is planted in a greenhouse, the temperature does not need to be adjusted, generally speaking it is more suitable. If you plant it at home, you need to protect it from the cold in winter. 2. Light: American ginseng is very afraid of strong light. Strong sunlight will not only hinder its growth, but may also cause it to suffer from "sunburn." Therefore, it is sufficient to provide astigmatism or diffuse light at ordinary times. Direct sunlight must be avoided, especially in summer, the best shading degree is between 70% and 75%. 3. Watering: American ginseng prefers a slightly dry environment. Too much moisture will have an adverse effect on it. Generally speaking, the moisture level of the soil should be between 25 and 30 percent, not too wet. 4. Fertilization: American ginseng does not require too much fertilizer and can only be used during June and July when it grows fastest. Foliar fertilization is usually used, usually one to three times. 2. Breeding techniques1. Reproduction: The most commonly used method is sowing. Its seeds have long-term dormancy characteristics, so they need to be germinated before sowing. The best time to sow is in February or March. The plant spacing can be five centimeters, and the row spacing can be about ten centimeters. After sowing, the thickness of the covering soil can be about three centimeters, and it needs to be covered with a layer of straw or fallen leaves to play a role in heat preservation and moisture retention. 2. Repotting: If it is a potted plant, it can be changed once a year or two. The size of the flowerpot can be determined according to the specific volume. If the plant grows very large, the flowerpot must be replaced as well. 3. Problem diagnosis and treatment1. Diseases: Common ones include "spot disease", "anthracnose" and "blight". In addition to spraying corresponding pesticides, the soil must be disinfected with lime, etc., and water and drainage must be controlled in time. 2. Pests: There are many types, such as cutworms, white grubs, wireworms, etc. You can use lights to lure and kill them, or you can use chemicals. IV. Other issues1. Toxicity: It is non-toxic and a tonic. 2. Can it be kept at home? Yes, but not often, because it is not mainly for viewing. |
