Each mu uses 3000 kilograms of high-quality soil fertilizer or 2000 kilograms of human feces and urine as the base fertilizer, the fertilizer and soil is mixed and crushed and leveled, and the greenhouse is 4-6 meters wide to make two high beds.

3. Sowing seeds

Winter parsley is generally sown from early October to mid-November and harvested from late November to March of the following year. Before sowing, the coriander seeds should be crushed and rubbed open to separate the seeds so that the seedlings can emerge evenly. It can be sowed with dry seeds or sowed after budding, and the latter can emerge 7-10 days earlier and emerge neatly.

When the seedling height is 2 cm, quick-acting nitrogen fertilizer can be applied with water; when the seedling height is 3-4 cm, weeding and thinning seedlings should be ploughed, and watering at seedling stage should not be too much; when the seedling height is about 10 cm, it should be watered frequently to keep the soil surface moist, and combined with watering and topdressing for 1-2 times, use more available nitrogen fertilizer.
