Note the growth Seeing the growth of cucumbers in greenhouses, usually when the cucumbers in the greenhouse are short of water, the leaves will wilt, the growth will weaken, and the disease will occur more frequently. At this time, water should be added in time. Pay attention to moisture Depends on the soil moisture, if watering the cucumbers in the greenhouse when the soil is not dry, not only is not conducive to raising the ground temperature, but also easy to lead to poor soil permeability, resulting in anoxic roots, resulting in root loss, yellow leaf phenomenon. Watch the weather Be sure to watch the weather forecast before watering, choose sunny watering, and ensure that there are 2-3 days of sunny days after watering to avoid rainy weather after watering, resulting in increased humidity in the shed, lower ground temperature, and frequent disease. In the current season, more attention should be paid to the fact that it is not suitable for watering in the first two days after a cloudy day, and the greenhouse temperature and ground temperature should be increased first to make the greenhouse cucumbers return to normal and then watered. Pay attention to the ground temperature The average daily ground temperature for cucumber growth in greenhouses is about 22 ℃, and the ground temperature in greenhouses 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 above ground. Growth, therefore, low temperature watering is best carried out after pulling the grass in the morning. Pay attention to covering the mulch Mulching plastic film 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. Watering cucumbers in greenhouses in spring generally follows the principles of no shortage and no watering, rather than dry and not wet. Keep the moisture content of the cucumber rhizosphere soil in the greenhouses at about 60% to prevent excessive over-watering and avoid flooding. Excessive watering is easy to reduce the temperature in the shed and increase the soil temperature, which is detrimental to the growth of vegetables. You should take a small water dip, or use a kettle to pour plant by plant. Pay attention to the management after watering After watering, the temperature was raised to about 40 ° C at noon in the first two days, and the shed was stuffed for 1 hour to increase the ground temperature in the shed. Then increase the amount of ventilation and reduce the humidity in the shed. Then, the cucumbers in greenhouses are easy to be diseased and sprayed to prevent the occurrence of pests and diseases.
