摘要
CO_2气体是作物进行光合作用必不可少的物质。选取同一种植基地的2个日光温室,比较3种CO_2增施设备对芹菜的增施效果,并比较经济效益,以筛选出成本低、效果突出的设备。结果显示,应用罐装CO_2设备增施CO_2种植芹菜,作物增产22.6%,经济效益增加53 359.5元/hm^2,是3种增施设备中投入成本最低、增施效果最好、经济效益增加最多的一种设备。
CO_2 gas is indispensable element in crop photosynthesis. Two solar greenhouses in the same planting base were selected. Increasing effect and economic benefit of three kinds of CO_2 increasing equipment for celery were compared to screen out the equipment that its cost was lowest,and effect was outstanding. Results showed that application of canned CO_2 to increasing CO_2 for celery could make crops yield increase 22. 6%,economic benefit increase 53 359. 5 yuan/hm^2. Its cost was the lowest,effect was the best,and increase of economic benefits was the most in 3 kinds of increasing equipment investments.
