合理浇水是保证温室蔬菜健壮生长、提高产量的重要措施。针对冬季温度低、棚内湿度大的问题,在给温室蔬菜浇水时应注意以下事项:1.注意长势。看植株长势,通常植株缺水时,叶片会萎蔫,长势会减弱,果实脐腐病发生较多,这时就应及时补充水分。2.注意墒情。要看土壤墒情,如果在温室土壤不旱时浇水,不但不利于提高地温,而且还容易导致土壤透气性变差,致使根系缺氧,造成沤根,出现黄叶现象。3.注意天气。在浇水之前一定要 Reasonable watering is to ensure the robust growth of greenhouse vegetables, an important measure to increase production. In view of the problem of low temperature in winter and large humidity in greenhouse, the following items should be noticed when watering vegetables in greenhouse: 1. Pay attention to the growth. See plant growth, usually when plants are dry, the leaves will wilting, the growth will be weakened, umbilical fruit rot occurred more, this time should be timely replenishment of water. 2. Attention to moisture. Depends on the soil moisture, if the water is not dry when the greenhouse watering, not only not conducive to raising the ground temperature, but also easily lead to poor soil permeability, resulting in hypoxia roots, resulting in the root, the phenomenon of yellow leaves. 3. Pay attention to the weather. Must be before watering
