Remove the plastic film or sunshade net after emergence to keep the border surface moist and promote growth.

Planting techniques:

First, variety selection: Jiaxing chicken crown dish.

2. Sowing and raising seedlings

1, soaking seeds to accelerate germination: generally, the time of soaking seeds should not exceed half an hour; the temperature for accelerating germination should be about 20 ℃. During the period of accelerating germination, the seeds should be often turned over and washed with clean water. The seeds of snow vegetables are small, and they usually begin to show white (that is, broken skin and germinate) in one day or two nights, and can be sown when 20% of the seeds are germinated.

2. Seedbed selection: the seedbed should be close to the field, the soil is fertile, the drainage is good, and the cruciferous crops have not been planted for many years, and it should be used as the clayey loam in the paddy field. If you choose dry land as a seedbed, it should be irrigated in deep water for 3-5 days before sowing, and then put water into dry ploughing, or film mulching and high temperature sterilization of topsoil after deep water flooding irrigation, so as to reduce bacterial infection.

3. Finishing nursery bed: the seedbed should be of high standard and flat. After ploughing, ditching and fine hoeing should be done so that the deep ditches are high, the soil on the border surface is fine, and the broken mud in the ditches should be cleaned up.

4. Apply sufficient basic fertilizer: 30 kg of superphosphate per mu of seedling bed is applied before soil preparation. After the completion of soil preparation, 1000 kg of rotten human faeces were used to irrigate the border surface, and 1000 times of Nongdile solution was used for soil treatment, in order to prevent underground pests from harming vegetable seedlings.
