Then every 10 square meters of high-quality manure applied sieved 100 kilograms, potassium dihydrogen phosphate 0.5 kilograms, fully mixed, after the leveling surface watering, water infiltration after seeding. Dry seeds are generally used for sowing, but they can also be sowed after germination. Dry seeds are sown with 75% chlorothalonil wettable powder at a seed weight of 0.3%, but should not be allowed to stand for too long. Immersion germination, should be soaked in warm water 20 °C 6 ~ 7 hours, remove and wrap it in a cloth bag, placed under 20 °C germination, washed with water once a day, 2 ~ 3 days after the buds.

Post-planting management
After daytime planting, the temperature was maintained at 20°C~24°C and the nighttime temperature was above 10°C. During the period of easing, cultivating loose soil 1~2 times. Appropriate cooling after easing the seedlings, during the day with 15 °C ~ 20 °C is appropriate, and in the 7 ~ 10 days after the slow emergence of seedlings watering, while light application of chemical fertilizer, applied per acre about 10 kg. Afterwards, cultivating again and seedlings appropriately. After about 15 days, when the rosette leaves have grown up and the heart leaves start to pack, 15 to 20 kg of compound fertilizer or ammonium nitrate is applied, and the fertilizer is topdressed once during the ball stage. The number of times of watering in winter should not be too much to prevent the ground temperature or humidity from being too high. When entering the ball stage, the water supply should be uniform. Do not dry or damp, so as to avoid cracking the ball or opening the ball.
