1、 Sowing time

Lotus seeds have no dormancy period, so they can be sown all year round, but the water temperature should be kept above 16 ℃. Under the condition of moderate temperature and light, it is conducive to its growth. After sowing, it is generally 50-60 days in spring and 60-80 days in winter and autumn

2、 Sowing method

1. Seed treatment: the shell of lotus seed is hard, so it is necessary to break before sowing. When breaking, it can be worn on the rough cement ground or clamped with pliers. Be careful not to pinch the seed blank or remove the shell

2. Sprouting: keep the water temperature at 20-30 ℃ in summer, and completely soak the seeds in a bowl or basin, and change the water twice a day. It can germinate in 7 days. After germination, keep ventilation and sufficient light, and do not lack water. Fine roots and small lotus leaves will grow after 2 weeks

3. Bud and seedling planting: select invincible hole or plastic flowerpot, add half a basin of pastoral soil in the basin, do not apply fertilizer, and directly press the fine roots of small lotus seedlings into the soil. Pay attention to proper watering. The water can't submerge the lotus leaves

3、 Daily maintenance

1. Watering: after 2-3 weeks of planting and transplanting, it enters the peak growth period. At this time, it should be watered frequently, especially to ensure that the water basin cannot be separated from water in summer. The rainfall is concentrated in the plum rain season. It should also be noted that the water level should not exceed the standing leaves, and the water should be drained in time

2. Fertilization: Lotus likes fertilizer, but it can't be applied too much, otherwise it will burn seedlings. In summer, phosphorus and potassium fertilizer should be the main fertilizer, and an appropriate amount of cake fertilizer or compound fertilizer can also be used. After summer, fertilizer can be applied every 15-20 days
