First, after the full-scale application of pedicure land, Mushi organic fertilizer 4000 ~ 5000 kg, 50 ~ 60 kg of available nitrogen fertilizer, 50 kg of phosphate fertilizer, 50 kg of potassium fertilizer. Second, stage fertilizer (1) seedling period: combined with thinning, cultivator light to mention the Miao Fei, Mu Shi human urine 500 to 750 kilograms, urea 5 to 10 kilograms, to promote seedlings robust growth. (2) Rosette period: Spring cabbage enters this period, the growth is obviously accelerated, and the amount of fertilizer needed is also increased. It is necessary to chase and apply fertilizer in a timely manner. Mushi quality farmyard fertilizer 1500 kg, urea 10-15 kg and moderate amount of phosphorus, Potash 5 to 10 kg.

In the seedling stage, the rosette stage and the bulbous stage, a strong Zhuangling solution was sprayed at the same time as the fertilization, which made the stems and stems of spring cabbage thick, thick leaves, fresh leaves, plants, and natural taste. At the same time, it can improve anti-disaster capacity and reduce the amount of pesticides and fertilizers. Third, the reasonable watering Spring cabbage needs a large amount of water throughout the entire growth period, each top dressing must be combined with watering, should control the seedling period of small watering, rosette period more pouring, enter the ball period every 5 to 7 days pouring water principle .
