    摘要:

    通过对常态下仙人掌科(Cactaceae)植物释放负离子的研究,以期筛选出可产生较高浓度负离子的仙人掌科植物,为具生态效应的室内美化植物选择提供理论基础。常态下在密闭玻璃箱内(800 mm× 800 mm×800 mm)测定和比较了6种(含种下分类单位及品种)仙人掌科植物产生的负离子浓度并通过逐步去刺试验研究了艳珠球(Mammillaria spinosissima ‘Pico’)刺的数量与负离子产生浓度的关系。结果表明,所有供试植物在自然状态下都能产生负离子,但产生负离子浓度均较低,且不同植物间产生负离子浓度有极显著性差异。以配对t检验结果来看,供试植物负离子产生浓度受空气中负离子浓度值影响显著。在逐步去刺试验中,艳珠球负离子产生浓度与刺的数量呈显著正相关。

    Abstract:

    In order to screen out ideal ecological and decorative indoor plants, the negative air ions (NAI) levels produced by 6 different cactaceous (including the taxa below species level and cultivars) were determined in a fabricated organic glass enclosure(800 mm× 800 mm×800 mm)in the natural state. The relationship between the NAI level produced by Mammillaria spinosissima ‘Pico’ and the number of spines was studied by gradually removing spines. The results showed that under the natural condition, all examined plants were able to generate a low level of NAI with a significant difference in different species. The paired t-test indicated that the NAI level was correlated with the background value in the air. On the other hand, a significantly positive correlation between the NAI level produced by Mammillaria spinosissima ‘Pico’ and its spine number was found in the gradually removing spine experiment.
