Protection of cucumber root system in winter greenhouse


1. Keep the ground temperature constant:

The optimum temperature is the key to the growth of cucumber. The optimum temperature for 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.

2. Reasonable watering and fertilization:

Too dry and wet soil will affect the growth of roots. Winter greenhouses should avoid flooding, especially in the deep winter. Fertilization should not apply excessive fertilizer once, easy to burn roots, can not apply high nitrogen fertilizer in winter, prevent ammonia volatilization and smoke cucumber.
