Winter cucumber root system management method:
Keeping the ground temperature constant, the optimum temperature for cucumber root growth is 20-22 degrees, the highest is 28 degrees, and the lowest is 8 degrees. If the temperature is below 12 degrees, root growth is hindered, and below 8 degrees, the roots stop growing, below 5 degrees, and are easily frozen. Maintaining the right temperature is therefore critical to plant growth.
Watering and fertilizing, the soil is too dry and wet will affect the growth of roots. In winter, greenhouses should avoid flooding, especially in the deep winter. Fertilizer should not apply excessive fertilizer once, can not apply excessive nitrogen fertilizer, prevent ammonia from volatilizing and smoking cucumber. After fertilization, photosynthetic nutrient film fertilizer can also be applied to increase the photosynthesis intensity of plants, and help plants absorb a lot of light energy and light to promote plant growth and development.
