A wide range of indoor air pollutants, including ammonia is one of the renovated building indoor air pollutants, which is characterized by a long incubation period lasting harm, can accumulate in the body, and eventually lead to the occurrence of a variety of disease complications, it is necessary to carry out the investigation and purification of ammonia in indoor air pollution, indoor ammonia pollution in order to get widespread attention and universal attention. In this paper, based on the survey of indoor ammonia pollution system study several foliage plants in ammonia pollution purification capacity and morphological characteristics, and on this basis, in-depth study of green dill on the form of ammonia pollution , cytology, and physiological and biochemical response, its conclusions are as follows: (1) the Heihe residential indoor ammonia pollution is widespread, and is closely related to the home decoration, indoor ammonia concentration decreased as decoration time extension, the future indoor air concentration of ammonia in the trend forecast fourth-order polynomial equation: y = 0.0128x ~ 4-0.1867x ~ 3 at 0.9933x to 2.4929x 3.1283 (of R ~~ 2 = 0.9787). (2) the use of smoked France, 12 potted foliage plants to absorb the effect of ammonia study results show that: 12 potted foliage plants purifying capability under different ammonia treatment is not the same, the overall unimodal curve trend. 24h fumigation, purification capacity of 12 kinds of potted foliage plants: Heart of Gold Chlorophytum> the Spirodela arrowroot, bumper Hong Green Dill mosaic cold water flowers, the variegated leaves Syngonium> the purple ducks toe grass mosaic duck foot wooden Swedish ivy, Phnom Penh Lucky Bamboo> Boston fern, coleus. 7d smoked processing, purification capacity of 12 kinds of potted foliage plants: green radish, a heart of gold Chlorophytum> the variegated leaves Syngonium, incense, mosaic cold water flowers, purple back bumper arrowroot> Phnom Penh, lucky bamboo, mosaic duck feet wood, Swedish ivy, purple duck toe grass> Boston fern, coleus. Coleus ammonia stress indicator plants. (3) green radish physiological resistance to ammonia stress research: the green dill potted leaf photosynthetic rate diurnal variation showed bimodal curve, the diurnal variation of transpiration rate compared with a single peak curve; 5.33mg / m ~ 3 (8.0ppm ) of the ammonia concentration for the green dill potted leaves by the critical concentration of stress; the green dill potted plants in different concentrations of ammonia treatment, photosynthetic rate, transpiration rate and stomatal conductance among presented in roughly the same trend between the three was a positive related. Main physiological indicators the green radish hydroponic Tony leaves: chlorophyll content, dry matter content, cell membrane permeability, MDA content, soluble protein content, NR activity, POD activity, SOD activity were tested significant linear relationship, and the difference was significant also has a similar process of change, and fumigation 3d 5.33mg / m ~~ 6.67mg/m3 the ammonia concentration as the green radish hydroponic Tony leaves turning conditions affected by stress.
