What are the characteristics of spinach high-yield and high-quality fertilizer? Vegetable growers who have grown spinach know that spinach has low soil requirements and wide adaptability. If you want to grow and produce pollution-free spinach products, you can have very strict ecological and soil conditions. Spinach is high-yield and high-quality, and it is hoped that it will help everyone. 1. Nutritional characteristics of the root system: The main root of spinach grows deep and is also very developed. The main root is slightly thicker and slightly expanded, storing nutrients, sweet and edible. The main root group is distributed in the 2525-30cm soil layer. The lateral roots are underdeveloped and therefore not suitable for transplanting. Spinach planting sites require no cotton in 3 years, and it is suitable for water, fertilizer, moisture, fertile neutral or slightly alkaline loam. 2, spinach need fertilizer dynamics: spinach growth period is short, fast growth, high yield, large amount of fertilizer, so it is required to have more nitrogen fertilizer to promote leaf plexus growth. When the ratio of nitrate nitrogen to ammonium nitrogen is above 2:1, the yield is higher. 3. Spinach is one of the vegetables with a high nitrate content. Spinach is mainly absorbed by nitrate nitrogen, and then reduced to nitrite or ammonium salt in the plant and reused. Therefore, the content of nitrate in spinach depends on the available nitrogen form and content in the soil, and the nitrate to plant. Absorption and transport, as well as the reduction of nitrates. 4, phosphate fertilizer has little effect on the content of nitrate in spinach, potassium can inhibit the reduction of nitrate, and the application of potassium fertilizer increases the nitrate and yield of spinach. 5. Sodium, calcium and magnesium have no direct effect on the nitrate content of spinach, and boron deficiency increases the nitrate content of spinach. 6. Soil type, soil pH, ecological factors and climatic conditions all affect the nitrate content in spinach. At the same time, when water and fertilizer are insufficient, spinach lacks nutrition, which affects the yield of commodities.
