Seven Kinds Of Common Indoor Plants Carbon Oxygen Release,and Interpretation Of The Water Absorption Ability Of Study In Jilin Province

In different indoor environments,the indoor plants through photosynthesis,transpiration can effectively exert the maximum ecological benefits,the choice of reasonable functional optimal plant is one of the effective ways to improve the indoor environment chamber.This paper takes 7 kinds of common indoor green plants of JiLin city:Spathiphyllum kochii Engl.& K.Krause?Hedera nepalensis var.sinensis?Tobl.?Rehd ? Peperomia obtusifolia A.Dietr ? Pachira macrocarpa Walp.? Dracaena sanderiana Sander?Calathea makoyana E.Morr?Gardenia jasminoides Ellis as the experiment material.Using single factor analysis and cluster analysis to compare and analyze the different plants in different seasons of carbon sequestration oxygen release?the water absorption of heat release results in order to adjust to choose the best plant indoor environment quality.The results show that:1.Between different plants,carbon sequestration ability to release oxygen,water absorption of heat release is different,even the same plant in different seasons of carbon sequestration ability to release oxygen?transpiration release water absorption capacity is different.Therefore,in the plant of different indoor space design,the function of the suitable plants is of great significance.The rational allocation of function plant is one of the important ways to improve the indoor environment.2.Carbon sequestration ability to release oxygen: according to the selected plant experimental research shows that under the condition of indoor cultivation carbon release oxygen ability the strongest is Gardenia jasminoides Ellis and Pachira macrocarpa Walp.,annual average carbon amount is higher than 1.5g.m^-2.d^-1,the average annual high oxygen release1.2g.m^-2.d^-1;Spathiphyllumkochii Engl.&K.Krause,Dracaena sanderiana Sander,round leaves pepper grass carbon sequestration ability to release oxygen medium,the average amount of carbon sequestration1.02 g.m^-2.d^-11.03 g.m^-2.d^-1,and the annual average oxygen release 0.74 g.m^-2.d^-10.75 g.m^-2.d^-1;Calathea makoyana E.Morr carbon sequestration ability to release oxygen is the most weak,the average amount of carbon sequestration in0.75 g.m^-2.d^-1the following,and release oxygen in 0.54 g.m^-2.d^-1 the following.All the selected plants performance is consistent: carbon oxygen release the highest in winter.Gardenia jasminoides Ellis,Pachira macrocarpa Walp.carbon release oxygen minimum season is summer,winter from a summer carbon amount is 1.84 times and1.84 times higher,respectively,release oxygen content is 1.84 times and 1.84 times higher,respectively;Calathea makoyana E.Morr carbon release oxygen minimum seasons are spring and winter than spring solid carbon,oxygen release were 6.96 and7.31 times respectively.3.The interpretation of the water absorption ability: through the experiment research shows that the Gardenia jasminoides Ellis and Pachira macrocarpa Walp.release water absorption capacity is usually the strongest,and moreover Spathiphyllumkochii Engl.&K.Krause is relatively strong,the average annual water release more than 1560 g.m^-2.d^-1above,heat absorption capacity more than3800 KJ.m^-2.d^-1 above;Dracaena sanderiana Sander release medium water absorption ability,an annual water release 921.44 g.m^-2.d^-1,the average annual heat absorption2250.55 KJ.m^-2.d^-1;Hederanepalensisvar.sinensis?Tobl.?Rehd,Peperomia obtusifolia A.Dietr,Calathea makoyana E.Morr release water absorption ability is weak,the average annual water release in 350 g.m^-2.d^-1 620 g.m^-2.d^-1,the average heat860 KJ.m^-2.d^-11515KJ.m^-2.d^-1.The selected plants release water heat absorption in winter is low,relatively high in spring and summer.4.Based on the main physiological indexes affecting the plant photosynthesis,transpiration,the correlation analysis showed that different seasons all selected plant photosynthetic rate and transpiration rate were significant or extremely significant relationship.But also exist significant correlation between stomatal conductance and relations,are the main factors influencing the photosynthesis,transpiration rate.
