一、选用无滴膜,采取增温排湿法。上午揭苫先放顶风15分钟左右,散出夜间的潮气,然后闭合风口迅速提温到32℃～33℃时,再打开风口,随高温把湿气排出室外。温室内要挂上干湿表,观察温湿度指标。如适宜黄瓜霜霉病发生的空气相对湿度是85％以上,适宜细菌性角斑病发生的空气相对湿度是70％以上,适宜番茄晚疫病发生的空气相对湿度是80％以上,适宜灰霉病发生的空气相对湿度是90％以上等等。以此标准调解室内的空气湿度。
First, the choice of non-drip film, take warm humidification method. Open the top of the morning to put the top wind for about 15 minutes, the night out of the moisture, and then close the outlet quickly warming to 32 ℃ ~ 33 ℃, and then open the outlet, with the humidity to the outdoor humidity. To hang the greenhouse wet and dry table, observe the temperature and humidity indicators. If the relative humidity of cucumber downy mildew is more than 85%, the relative air humidity suitable for bacterial angular leaf spot is more than 70%, the relative humidity of suitable air for tomato late blight is more than 80%, and the suitable gray mold Occurrence of air relative humidity is more than 90% and so on. Use this standard to mediate indoor air humidity.
