目前,利用太阳能养护构件越来越普遍,采用的形式大体有集热式和直接覆盖式两类。南方炎热地区,直接覆盖式采用得比较广泛。这种方法一年四季均可采用,与传统的盖草帘浇水养护法相比,具有明显的技术经济效益。我厂从1981年起开始对各种养护方式进行了生产性试验,去年把太阳能养护正式作为一项技术措施,应用于生产实际。我们采取的养护形式是:在高温季节采用黑色塑料薄膜覆盖养护,在低温季节采用黑色塑料薄膜外加二层草帘养护。但是,在应用中我们也发现了一些问题,其中尤为突出的就是在
At present, the use of solar energy curing components is becoming more and more common, and there are generally two types of solar collectors: direct collectors and direct collectors. In the hot regions of the South, direct coverage is used more widely. This method can be used all year round, and has obvious technical and economic benefits compared to the conventional cover straw watering and conservation methods. Since 1981, our factory has carried out production tests on various maintenance methods. Last year, solar energy conservation was formally adopted as a technical measure and applied to production. We adopt the following forms of conservation: the use of black plastic film covering and curing in the hot season, and black plastic film plus two layers of straw curtains in the cold season. However, we have also found some problems in the application, among which the most prominent
