为提高我国北方温室生产蔬菜的经济效益,研制了适应我国国情、采用无土栽培和蔬菜—食用菌互补栽培的日光温室。本文论述了该温室及栽培设施的结构特征与设计参数。经使用测试表明:当京郊冬季夜间气温降至-13℃时,温室内不加温运行,气温为5.45℃;互补栽培使温室有效面积利用率达117.6％;菇—菜共生,解决了蔬菜生产的CO_2施肥问题,使冬茬黄瓜增产25％左右。
In order to improve the economic benefits of greenhouse vegetable production in northern China, a solar greenhouse adapted to China’s national conditions and cultivated with soilless cultivation and vegetable-edible mushroom cultivation was developed. This paper discusses the structure characteristics and design parameters of the greenhouse and cultivation facilities. The test showed that when the nighttime temperature in the suburbs of Beijing dropped to -13 ℃ in winter, the temperature in the greenhouse was 5.45 ℃ and the utilization rate of effective area in greenhouse reached 117.6%. The mushroom-vegetable symbiosis solved the problem of vegetables Production of CO 2 fertilizer problems, winter cucumber yield 25%.
