温室蔬菜浇水,既要看天,又要看地、看苗情,一般来说要掌握以下几项浇水技巧: 1.苗期少浇水温室蔬菜在播种前浇透水后,一般苗期不浇水,以防秧苗因水分过大、徒长而影响产量。如果苗期缺水,浇透即可,不宜过多浇水。 2.早晨浇水早晨地温、水温较相近。浇水后白天温度高,地温亦可提高。傍晚不宜浇水,以防降低夜间温室内室温和地温。 3.浇水量不宜过大在严寒的冬季温室内气温和地温比较低,浇水量要小,切忌大水漫灌,以防低温高湿而引起蔬菜沤根等多种病害发生。
Greenhouse watering vegetables, it is necessary to see the sky, but also to see, to see Miao, in general, to grasp the following watering tips: 1. Seedlings less watering greenhouse vegetables before sowing water, the general seedling Do not watering to prevent seedlings due to excessive water, leggy and affect the yield. If the seedling water, pouring can be, not too much water. 2 morning watering ground temperature, water temperature is similar. High temperature during the day after watering, ground temperature can be increased. Watering should not be evening, to prevent the night to reduce the temperature inside the greenhouse warm. 3. The amount of water should not be too large In the cold winter greenhouse temperature and ground temperature is relatively low, the amount of water to be small, avoid flood irrigation, to prevent low temperature and humidity caused by vegetables and other root diseases occur.
