Pay attention to the soil moisture and check the soil moisture. If watering the cucumber soil in the greenhouse is not dry, it will not only help to increase the ground temperature, but also lead to poor soil permeability, resulting in anoxic roots, resulting in root loss and yellow leaf phenomenon.

Pay attention to the weather and choose sunny watering to ensure that there are two to three days of sunny days after watering to avoid rainy weather after watering, resulting in increased humidity in the shed, lower ground temperature, and frequent diseases.

Pay attention to that the average daily ground temperature for cucumber growth in greenhouses is about 22 ℃, and the ground temperature in the greenhouse is mostly 15 ℃ -20 ℃. If the watering is excessive or the timing of watering is wrong, the ground temperature will drop rapidly, causing root injury and endangering the plant. Growth, therefore, low temperature watering is best carried out after pulling the grass in the morning.

Note that mulching mulch can not only reduce ground water evaporation, maintain soil moisture, reduce watering times, reduce air humidity, reduce disease occurrence, but also increase ground temperature and accelerate the growth rate of greenhouse cucumbers.

Pay attention to the management after watering. After the watering, the temperature was raised to about 40 ° C at noon in the first two days. Then increase the amount of ventilation and reduce the humidity in the shed. Then, the cucumbers in the greenhouse are prone to disease and spray prevention to reduce the occurrence of pests and diseases.
