Sowing sooner or later is closely related to the overwintering ability, harvest time and yield of seedlings, which should not be too early or too late. Spinach is best with 4-5 leaves before it freezes. Overwintering spinach is sown from mid-October to early November. At this time, the climate is cool, suitable for spinach germination and emergence, generally do not need to sow bud seeds, sow dry seeds and wet seeds. The seed was mixed with new high-fat membrane before sowing to improve the seed germination rate.

Topdressing overwintering fertilizer can increase the content of soil nutrients, which can be used in winter and spring, and promote the weak to become strong. It is especially important for vegetable fields with low base fertilizer, poor soil fertility and weak seedling condition. Therefore, it should be combined with pouring frozen water to apply overwintering fertilizer, generally applying urea or ammonium sulfate per mu, and topdressing with water. And spraying photosynthetic nutrient film fertilizer can help plants absorb a large amount of light fertilizer, light energy, light, compatible conventional fertilizers and nutrients to the limit of plant growth and development. One application is beneficial for the whole year.

When the leaves are growing vigorously, topdressing nitrogen fertilizer once, applying 10 kg urea per mu, sprinkling it on the border after the dew on the leaves disappears near noon, dipping it with a new broom, watering the border one by one, and spraying vegetable Zhuangxanling timely during the growing period of spinach, it can improve the ability to resist disasters, reduce the amount of pesticide and chemical fertilizer, and reduce residual poison.
