兰棚通风的作用 空气流通,可以改善兰花生长环境的温度和湿度,有利于兰花正常生长,也能及时补充因光合作用而消耗的二氧化碳,从而提高光合效率。调控兰棚相对湿度至关重要,因为白粉病、黑斑病、炭疽病、蚜虫、介壳虫等病虫害的发生都与湿度有关,因此,如果相对湿度调控得好,就可以有效地抑制病虫害的发生。 四季通风要求 春季,兰棚、兰圃湿度过大,但温度不高,因此,必须抓好通风散湿。夏季,由于炎炎烈日,兰棚、兰围温度过高,所以,单靠通风还不行,还应采取高压喷雾的方法降温。若通风与高压喷雾结合起来,降温又保温,效果更好。兰花生长适宜的相对湿度
The effect of ventilation through the shed can improve the photosynthetic efficiency by improving the temperature and humidity of the orchid growth environment. It is also conducive to the normal growth of orchids and the timely replenishment of carbon dioxide consumed by photosynthesis. It is very important to control the relative humidity of orchid shed because the incidence of diseases such as powdery mildew, black spot, anthracnose, aphids and scale insects are related to the humidity. Therefore, if the relative humidity is well regulated, the occurrence of pests and diseases can be effectively suppressed . Four Seasons Ventilation Requirements Spring, orchid shed, orchid garden humidity is too large, but the temperature is not high, therefore, must do a good job of ventilation and wetting. Summer, due to the scorching sun, blue shed, blue ambient temperature is too high, so ventilation alone is not enough, but also to take high-pressure spray cooling. If the combination of ventilation and high pressure spray, cooling and insulation, the effect is better. Orchid growth suitable for relative humidity
