【摘要】：在不同的室内环境中,室内植物通过光合作用、蒸腾作用能有效发挥其最大生态效益,合理的选择功能性最优植物也是室内环境改善有效途径之一。本文以吉林省常见的7种室内绿色植物白鹤芋(Spathiphyllum kochii Engl.K.Krause)、常春藤(Hedera nepalensis var.sinensis(Tobl.)Rehd)、圆叶椒草(豆瓣绿)(Peperomia obtusifolia A.Dietr)、马拉巴栗(发财树)(Pachira macrocarpa Walp.)、富贵竹(Dracaena sanderiana Sander)、孔雀竹芋(Calathea makoyana E.Morr)、栀子(Gardenia jasminoides Ellis)为实验材料,应用单因素分析法和聚类分析法,对不同植物在不同季节的固碳释氧、释水吸热量结果进行比较分析,以期为调节室内环境质量选择最佳植物。结果表明:1.不同植物间的固碳释氧能力、释水吸热能力不同,即便是同种植物在不同季节的固碳释氧能力、蒸腾释水吸热能力也存在差异。因此,在不同室内空间的植物设计中,选择适宜的功能植物具有重要意义。合理配置功能植物是改善室内环境的重要途径之一。2.固碳释氧能力:针对供试植物实验研究表明,在室内栽培条件下固碳释氧能力最强的是栀子和马拉巴栗,年均固碳量高于1.5g.m~(-2).d~(-1)、年均释氧量高1.2g.m~(-2).d~(-1);白鹤芋、富贵竹固碳释氧能力中等,年均固碳量1.02g.m~(-2).d~(-1)~1.03g.m~(-2).d~(-1)、年均释氧量0.74g.m~(-2).d~(-1)~0.75g.m~(-2).d~(-1);孔雀竹芋固碳释氧能力最弱,年均固碳量在0.75g.m~(-2).d~(-1)以下、释氧量在0.54g.m~(-2).d~(-1)以下。所有供试植物表现一致的是:冬季固碳释氧量最高。栀子、马拉巴栗固碳释氧最低的季节均是夏季,冬季较夏季固碳量分别高出1.84倍和3.25倍,释氧量分别高出1.84倍和3.26倍;孔雀竹芋固碳释氧最低的季节是春季,冬季较春季固碳量、释氧量分别高出6.96和7.31倍。3.释水吸热能力:通过相关实验研究表明,栀子和马拉巴栗的释水吸热能力依然最强,此外白鹤芋能力也相对较强,年均释水量超过1560g.m~(-2).d~(-1)以上、年吸热量超过3800KJ.m~(-2).d~(-1)以上;富贵竹的释水吸热能力较中等,年均释水量在921.44g.m~(-2).d~(-1)、年均吸热量2250.55KJ.m~(-2).d~(-1);常春藤、圆叶椒草、孔雀竹芋释水吸热能力较弱,年均释水量在350g.m~(-2).d~(-1)~620g.m~(-2).d~(-1)、年均吸热量860KJ.m~(-2).d~(-1)~1515KJ.m~(-2).d~(-1)。供试植物在冬季释水吸热量较低,在春夏季相对较高。4.通过对影响植物光合、蒸腾作用的主要生理指标相关性分析表明,不同季节所有供试植物光合速率与蒸腾速率之间均存在显著或极显著关系。而气孔导度与两者之间亦存在显著相关关系,是影响光合、蒸腾速率的主要因素。
[Abstract]:In different indoor environments, indoor plants can effectively exert their maximum ecological benefits through photosynthesis and transpiration. It is also one of the effective ways to improve the indoor environment by reasonably selecting the best plants of function. In this paper, seven common indoor green plants, Spathiphyllum kochii Engl.K. Krauseus, Hedera nepalensis var. sinensis Tobl.Rehdr, Peperomia obtusifolia A. Dietrus, Malabar. Chestnut (Pachira macrocarpa Walp.Li, Dracaena sanderiana Sandera, Calathea makoyana E. Morrus, Gardenia jasminoides Ellis. jasminoides) were used as experimental materials. Single factor analysis and cluster analysis were used to compare and analyze the results of carbon sequestration and heat absorption of different plants in different seasons. The results showed that the ability of carbon sequestration and heat release was different among different plants, even the carbon sequestration and oxygen release ability of the same plant in different seasons. There are also differences in the heat absorption capacity of transpiration and water release. Therefore, in the plant design of different indoor spaces, It is of great significance to select suitable functional plants. Rational allocation of functional plants is one of the important ways to improve the indoor environment. 2. The ability of carbon sequestration and oxygen release. Under the condition of indoor cultivation, Gardenia jasminoides and Malaba chestnut had the strongest carbon sequestration capacity, the average annual carbon sequestration capacity was higher than 1.5 g 路m ~ (-1) ~ (-1), the annual oxygen release capacity was 1.2 g 路m ~ (-1) ~ (-2) C ~ (2) C ~ (-1), and the ability of white crane taro was medium. The average annual carbon sequestration capacity is 1.02g 路m ~ (-1) ~ (-1). The average annual oxygen release is 0.74 g 路m ~ (-1) ~ (-2). The average annual oxygen release is 0.74 g 路m ~ (-1) ~ (-2) 路m ~ (-1). The ability of carbon sequestration is the weakest, the annual carbon sequestration capacity is below 0.75 g 路m ~ (-1) and the oxygen release is below 0.54 g 路m ~ (-2) 路d ~ (-1). All the tested plants have the same ability of carbon sequestration and oxygen release in winter, which is the highest in winter, and the highest in winter, and the highest in winter, the highest carbon sequestration is observed in all the tested plants, and the highest carbon sequestration capacity is found in winter, and the average annual carbon sequestration capacity is less than 0.75 g 路m ~ (-1) and 0.54 g 路m ~ (-1) 路d ~ (-1). The lowest season of carbon and oxygen release from Malaba is summer, and the carbon sequestration in winter is 1.84 times and 3.25 times higher than that in summer, and the oxygen release is 1.84 and 3.26 times higher than that in summer, respectively, while the lowest season for carbon and oxygen release in Peacock is spring, and the carbon sequestration in winter is higher than that in spring. The oxygen release capacity was 6.96 and 7.31 times higher than that of 6.96 and 7.31 times respectively. The experimental results showed that Gardenia jasminoides and Malaba chestnut still had the strongest water release and heat absorption capacity, and that the average annual water release of Gardenia jasminoides var. jasminoides was higher than 1560g / kg / year. The annual endothermic capacity of Phyllostachys nobilis is more than 3800KJ. mechnian.dc-1); the average annual water release capacity of Phyllostachys nobilis is 921.44 g / m ~ (-1). The annual heat absorption capacity is 2250.55 KJ 路mGG ~ (-2) 路d-1 ~ (-1); the annual heat absorption capacity of Phyllostachys lucifera is low, and the water and heat absorption capacity of phyllostachys lucifera is weak, and the annual heat absorption capacity of Phyllostachys oleifera is relatively low. The average annual water release is at 350 g 路m ~ (-1) ~ (-1) ~ 620g 路m ~ (-1) ~ (-1) ~ 620g 路m ~ (-1) ~ (-1), and the average annual heat absorption is 860KJ 路m ~ (-1). The correlation analysis of the main physiological indexes of the effects on photosynthesis and transpiration shows that the water and heat absorption of the tested plants is low in winter and relatively high in spring and summer, and the correlation analysis of the main physiological indexes influencing the photosynthesis and transpiration of the plants shows that the main physiological indexes of the plants in the experiment are lower in winter and higher in the spring and summer. The results show that the main physiological indexes affecting the photosynthesis and transpiration of the plants are as follows:. There was a significant or extremely significant relationship between photosynthesis rate and transpiration rate in all the tested plants in different seasons, and there was also a significant correlation between stomatal conductance and transpiration rate, which was the main factor affecting photosynthesis and transpiration rate.
