【摘要】 1995～1997年，在日光温室内进行了人工增施CO2试验，使温室内CO2浓度达到800～1000mg／kg。结果表明，叶片光合作用强度提高，叶片数和瓜码数分别增加9％和46．6％，根系鲜重提高8．2％，产量达13．86万kg／hm2，产值1．55万元／hm2，投入产出比为1∶10．3更多还原

【Abstract】 A experiment of adding CO2 was conducted in the sunlight greenhouse in 1995 ～ 1997. When the concentration of CO2 was added to 800 ～ 1000mg/kg, the photosynthesis intensity was increased.Leaf number was inercased by 9%. The melon number was increased by 46. 6%. The fresh weight of root was increased by 8. 2%. Output reached 138 600kg/hm2. Output value reached 232 500yuan/hm2.The ratio of investment to output was 1∶ 10. 3.更多还原
