绥化市东兴办事处工农管理区刘志芹在两栋大棚中种植黄瓜。他考虑密闭的大棚中CO_2气体的浓度远远不能满足植物的光合作用的需要,于是采用CO_2气体施肥法,加强植物的光合作用,并在两棚中进行对照试验。实践证明,大棚黄瓜应用CO_2气体施肥效果显著:施气棚产量1503斤,对照棚产量1389斤,增产14.6％;施气棚收入780.50元,对照棚收入666.50元,增收18.63％。 Suihua Dongxing Office workers and peasants management area Liu Zhiqin cucumber planting in two greenhouses. He considered the concentration of CO 2 gas in a closed greenhouse can not meet the needs of photosynthesis plants, so the use of CO 2 gas fertilization method to enhance photosynthesis of plants and in the two controlled experiments. Practice has proved that the greenhouse cucumber application of CO 2 gas fertilization effect is obvious: gas shed production 1503 kg, control shed yield 1389 catties, an increase of 14.6%; greenhouse income 780.50 yuan, control studio income 666.50 yuan, an increase of 18.63%.
