two。 Ecological habits. Like warmth, like light, afraid of cold. The requirement of soil quality is not strict, the acid soil in the south and the alkaline soil in the north can grow, and the fertile and loose sandy neutral soil is better. It is more resistant to drought and long-term waterlogging is disadvantageous to its growth. The best temperature for growth and flowering was 15: 35 ℃. It could grow normally at 7-38 ℃, and the growth was retarded below 5 ℃ or above 38 ℃. In the northern region, the temperature below 3 ℃ for a long time after autumn will wither.

3. Cultivation and management. Sowing and raising seedlings from February to March in the south and from March to April in the north. Sowing depth 0.3cm, keep the soil moist, keep the temperature 1530 ℃, emerge in 5 days, seedlings with 5 leaves can transplant with soil. Potted plants use pots with a diameter of 15 centimeters and 25 centimeters, 1 plant per pot, 60 centimeters between flower beds and field plants, and 20 centimeters between plants. Pour water thoroughly after planting, and then pour it again when it is dry. No stagnant water is left at the root of quick pouring. Drainage and waterlogging prevention in rainy season.
