草莓是奈良县的主要作物。以前,草莓大棚在早晨施用CO_2,效果不够明显,本试验全天施用CO_2,得到了很明显的效果。供试品种为宝交早生、女峰等。使用液体碳酸,用红外线分析仪测量浓度,并用与之连动的控制器,从早晨9时到傍晚5时,控制在设定浓度375、500和750mg/L±100mg/L的范围内。CO_2施用区的换气温度高达25～3O℃。施用气
Strawberry is the main crop in Nara Prefecture. In the past, the application of CO_2 in strawberry greenhouses in the morning did not show enough effect. CO 2 was applied throughout the experiment, and the obvious effect was obtained. Test varieties for the Bao Zhaosheng, female peak and so on. Using liquid carbonic acid, the concentration was measured with an infrared analyzer and controlled by a controller linked to it at a set concentration of 375, 500 and 750 mg / L ± 100 mg / L from 9:00 am to 5:00 pm. The ventilation temperature of CO_2 application zone is up to 25 ~ 30 ℃. Apply gas
