Spinach is an overwintering vegetable harvested in autumn sowing. It starts to bloom from the end of November to return to green in early March and lasts for more than 100 days. Therefore, under conditions of long-term low temperature and dryness, how to ensure safe wintering is the key to winning the harvest.
Pouring frozen frozen water to seal frozen water must be "certain" and "secondary". "Determined" is based on the amount of soil moisture decided not to pouring frozen water. Generally, the absolute water content of sandy loam is less than 15%, the loam is less than 17%, and frozen water should be poured when the clay is below 20%. "Two kinds of fitness" means timely watering and proper watering. The suitable time for freezing and freezing water is that the soil can be thawed during the day and frozen at night. The proper amount of water means that the amount of frozen water cannot be too large or too small. It is generally appropriate to connect the bottom of the floor.

Therefore, should be combined with pouring frozen water topdressing overwintering fertilizer, usually mu urea 10 kg or ammonium sulfate 20 kg, with the water topdressing.
The cold weather in the northern part of the cold-proof area is very unfavorable for safe wintering of the seedlings. Therefore, the cover should be used to prevent cold and ensure that the seedlings can safely pass winter. Coverage can generally be carried out after all the soil in the plough layer is frozen. Covers are organic fertilizers that have been broken down and finely crushed by farmhouse fertilizers. About 1,000 kilograms of mu can be sprinkled.
