由于日光温室黄瓜的生产主要利用太阳光,所以连阴天是最主要的灾害。近年来,我县经受了多次秋冬季节连阴天灾害,由于我们提早加强了有关技术的研究和推广工作,使损失大大减轻。总结几年防御连阴天灾害的经验,我们认为下面几点很重要。 As the production of the greenhouse cucumber mainly uses sunlight, so even cloudy is the most important disaster. In recent years, our county has suffered many cloudy and even cloudy winter disasters. As we stepped up the research and promotion of technologies earlier, the losses have been greatly reduced. To sum up the years of experience in defense against catastrophic catastrophes, we think the following points are very important.
