Autumn spinach is the overwintering vegetable harvested in autumn sowing. It starts to return from winter at the end of November to return to green at the beginning of March in the second year of the year. The time is 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. .
One must pour frozen water. Pouring 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 soil is less than 15%, and frozen water should be poured when the clay is below 20%. "Two kinds of fitness" means timely watering and proper watering. The time suitable for pouring frozen water is when the soil tillage layer can be defrosted. The proper amount of water means that the amount of frozen water should not be too large or too small, and it is generally advisable to connect it to the bottom.
Second, we must catch up with winter fertilizers. Over-the-counter winter fertilizers can play a role in winter fertilizers and promote weak and strong growth, especially for less-fertilized, poorly-fertilized and weak-seedling vegetable lands. Generally, 10 mu of urea or 20 kg of ammonium sulfate is applied, and fertilizer is added with water.
Third, we must do a good job of soil coverage. 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.
