Detailed Explanation of Humidity Control Techniques for Greenhouse Cherries
From covering the greenhouse to harvest, the soil relative humidity is required to be 60%-80%; from the early germination stage to before initial flowering, 80% is optimal; during the germination stage, the humidity of the soil at 20-40 cm should be such that when soil is squeezed in the hand it forms a ball, and when the hand is released it crumbles. After the flowering stage, the soil relative humidity should be 60%-70%. For air humidity, from covering the greenhouse to the germination stage, maintain relative...
From covering the greenhouse to harvest, the soil relative humidity is required to be 60%-80%; from the early germination stage to before initial flowering, 80% is optimal; during the germination stage, the humidity of the soil at 20-40 cm should be such that when soil is squeezed in the hand it forms a ball, and when the hand is released it crumbles. After the flowering stage, the soil relative humidity should be 60%-70%.
For air humidity, from covering the greenhouse to the germination stage, maintain a relative humidity of 80%; if too low, germination and flowering will be uneven. From flowering to the petal-fall stage, maintain 60%; during the fruit enlargement stage, 60%; during the fruit coloring stage, 50%. The flowering stage of cherries has relatively strict requirements for air humidity; if humidity is too high, pollen disperses easily and flowers are prone to blossom blight; if humidity is too low, the stigma dries out, which is unfavorable for fertilization.
