1. Maintenance methods

1. Temperature: Jerusalem artichoke does not have high requirements for it and has good adaptability. The most suitable temperature for it is between 18 and 22 degrees, but a slightly higher or lower temperature will not affect its growth. In winter, its tubers can tolerate temperatures as low as minus 30 degrees Celsius. However, if it is the above-ground part, it cannot be lower than minus five degrees.

2. Light: Jerusalem artichoke is a sun-loving plant. Generally speaking, its tubers can form and grow better if the light is maintained for about twelve hours a day. However, try to avoid too strong sunlight.

3. Watering: Jerusalem artichoke has very strong drought resistance. Not much water required. Moreover, its waterlogging resistance is not very good. Therefore, when replenishing water, you can replenish it after the substrate is dry, and no water can accumulate. For large-scale planting, it is necessary to prevent waterlogging and drain water during the rainy season.

4. Fertilization: Jerusalem artichoke does not have high requirements for nutrients in the soil. Just choose soil with the right amount of nutrients, and usually very little fertilizer is needed. Generally speaking, you only need to fertilize twice during the growing period. Once around May, urea was used. Once during the budding stage, use potassium sulfate.

2. Breeding skills

1 , Reproduction: Seed reproduction can be used. It is best to sow seeds in the spring, after the thaw. Choose suitable tuber seeds. When sowing, control the depth at ten to twenty centimeters, the row spacing at 0.5 meters, and the plant spacing at 0.5 meters.

2. Pruning: Usually, the main task is to properly repair its branches and leaves. Because it has high requirements for sunlight, if it is too dense and messy, it will seriously affect the light transmission. In addition, after the flowering period, the remaining flowers and flower branches also need to be repaired.

3. Problem diagnosis and treatment

1 , Diseases: The main one is "rust". The disease-causing spores will overwinter on the plants and cause disease when temperatures warm up the following year. It can be treated with fentanin. In addition, diseased plants need to be treated in time, and then attention should be paid to drainage, density control, etc.

2. Pests: Jerusalem artichokes are rarely affected by pests. If there are signs of pests, deal with them in time.
