摘要
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。
Economicefficiency of vegetable production in plastic greenhouse can be improved bythree ways. Because of adopted the new structure of greenhouse th e heatingcost is saved. It can absorb solar energy in the maximum limit in the daytime and lose heat in the minimum limit in the nightime during winter in Beijing. The temperature in the greenhouse is 15.45℃ when outside is -13℃ . Secondly, the utilization ratio of the area in the greenhouse is increased up to 117.6% by adopting soilless culture and mutually beneficial growth of vegetables and mushrooms. Finally, because of mutually beneficial growth of vegetables and mushrooms in the greenhouse, the plants absorb carbon dioxide that is produced by mushrooms, increase the yields of vegetables and eliminate adverse effect on mushroom growth. The experi ment on cucumbers has showed thatthe yield can be increased by 25%.
