Overwinter Spinach Precision Cultivation Essentials
In the winter, the fields of fertile soil, good heat preservation and water retention should be selected in the spinach field, and the fields should be intensively cultivated and leveled. Make sure to keep a moderately clear wind barrier when setting up the site. Before the wintering spinach stopped growing, when the plants reached 5-6 leaves, they had stronger cold-resistance. Therefore, when the average temperature dropped to 17°C-19°C on that day, it was the best choice for sowing. Seeds were first soaked in warm water at 35°C for 12 hours, then they were sprayed out for drying and sowing or drilling. After the sowing, they were stepped on and sprinkled with water. Then, the surface of the soil is sprayed with 600-times new high-fat film 600 to protect the water from evaporation, sun protection, drought resistance, heat preservation and anti-freeze, anti-soil compaction, suffocation and isolation of pests and diseases, and increase the emergence rate.
Pre-winter management After the spinach is sprouted and unearthed, it is necessary to perform a shallow hoeing for the weed control. When the plant grows 3-4 leaves, keep the soil moist and apply fertilizer as appropriate; when the plant grows 5-6 leaves will stop growing, it is necessary to timely seal the frozen water, the timing of watering should be controlled by the soil surface. Frozen night. Pouring water is best to use manure, which is conducive to spinach accelerated growth in early spring.
