Autumn spinach is the overwintering vegetable harvested in autumn sowing. It starts to overwinter from November to the third year in early March and early April. It lasts for more than 100 days. Therefore, under conditions of long-term low temperature, how to ensure safe wintering is a good harvest. The essential. Pouring 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 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 defrosted during the day and there is freezing at night. The proper amount of water means that the amount of frozen water cannot be too large or too small, and generally it is appropriate to connect the bottom of the soil. Covers protect against cold. Absolute low temperature during the cold period in the northern region is very unfavorable for safe wintering of the seedlings. Therefore, the cover should be used to prevent cold and ensure that the seedlings safely pass through the 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. Doing Well Overwintering Spinach Pest Control: Overwintering spinach diseases and pests mainly include downy mildew, anthrax, viral diseases, and roundworms. Downy mildew and anthrax can be treated with 75% chlorothalonil 600x, 25% metalaxyl 700-800x, or 40% ethoxyphos WP 200-300x at the onset of the disease. In addition to the rotation of virus diseases, it is also necessary to prevent and control locusts and other transmission media. Aphids can be controlled by imidacloprid and other agents.

Keep up with wintering fertilizers. Over-wintering fertilizer can increase soil nutrient content, play a role in winter fertilizer, and promote weak and strong. In particular, it is more important for less-fertilized, poorly-fertilized, and weak-seated vegetable plots. 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.
