The seeding amount of spinach seeds should be determined according to different regions and harvesting methods.

General warm sowing should be sparse, cold sowing should be dense, the growth period of disposable harvest should be sparse, sub-harvest more appropriate. The amount of sowing affects the cold resistance and yield of plants. Too much sowing, seedling performance is too dense, easy to grow, so that the root growth is poor, affecting plant robustness and nutrient accumulation, poor cold resistance, more dead seedlings in winter, more bolting in the following year, affecting yield and quality. However, if the spinach seeds are sown late, or if the seedling stage needs to be divided into seedlings, it can be properly dense, the sowing amount is too small, the number of plants in the unit area is less, and also affects the yield.

The average maximum temperature in winter in 10 makes the root growth poor, affecting the robustness and nutrient accumulation of spinach seeds, poor cold resistance, many dead seedlings in winter, more bolting in the following year, affecting yield and quality. However, if the sowing is late, or if the seedling stage needs to be divided into seedlings, it can be properly dense, the amount of sowing is too small, the number of plants in the unit area is less, also affects the yield.
