After taking out, wash it with water(plug trays), then put it in 55 °C warm water, stir constantly, soak for 15min.  The substrate should be kept moist until the cotyledons are unearthed, that is, the substrate moisture is between 70% and 80%. After the seedlings grow out of the true leaves, the film can be uncovered at 10:00 am, and the leaves are dried and then covered with a film(21 cell trays bulk). If the temperature in the day shed is lower than 15 °C, do not water the topsoil, and the substrate moisture after the cotyledons are excavated should be 60%~70%.

The seedling stage is most afraid of encountering cold weather(cell trays). Special attention should be paid to cold insulation. If the daytime temperature is high, the film cooling at both ends can be uncovered. 7 days before planting, use the fine weather in the day to uncover the film and control the water. When it is applied, the remaining 1/3 is applied when the dough is ditched(50 cell trays bulk), and the plow is even. The herbicide is sprayed with 100 g/667 m2 of metolachlor to 60-80 kg of water.


Planting points were set at a predetermined plant spacing 7 days before planting, and herbicides(wholesale nursery pots), fungicides and insecticides were applied. Then, the sterilizing agent is mixed in a ratio of 1 part of 50% carbendazim powder and 100 parts of soil, and 0.25 kg is applied per hole.
