一九六四年十二月,我们和北京市某农场合作,设计并建成了一个日光温室(图1)。这个温室,完全不烧煤火,而是利用日光的热量保持室温,生产蔬菜的。它不但节约了煤和温室的管理人员,而且产量增多(图2),成本降低。北京市农林局曾为此召开了现场会。接着,北京市四季青人民公社和玉渊潭人民公社等也都把部分用煤火加温的旧温室改造成日光温室。无论在改建或试建的日光温室,蔬菜生产都是增产的。公社社员和农业科学工作者认为:日光温室的经济效果十分显著,而且很容易建造,这对
In December 1964, we collaborated with a farm in Beijing to design and build a solar greenhouse (Figure 1). This greenhouse does not burn coal fire at all, but uses the heat of sunlight to keep room temperature and produce vegetables. It not only saves coal and greenhouse managers, but also increases production (Figure 2) and reduces costs. The Beijing Municipal Bureau of Agriculture and Forestry held a live meeting for this purpose. Then, the Beijing Sijiqing People’s Commune and Yuyuantan People’s Commune also transformed some of the old greenhouses that were heated by coal fire into a solar greenhouse. No matter in the reconstructed or piloted solar greenhouses, vegetable production is increasing production. Commune members and agricultural scientists believe that the economic effects of solar greenhouses are very significant and they are easy to build.
