摘要/Abstract

摘要： 研究中水对植物生长发育产生的影响,拓展深圳市中水的利用范围。利用中水和清水(对照)水培试验对大叶油草、台湾草、蟛蜞菊和金叶假连翘4种常用绿地植物小苗进行培养,测定2种水质对4种绿地植物株高生长、根系发育及光合生理等的影响。结果表明,在中水中培养30d,4种植物的株高大于清水;根活力小于相应的清水;叶绿素含量都高于清水;而根长在培养21d前大于清水,在21d后小于清水。大叶油草、蟛蜞菊的原始荧光(F₀)和最大荧光(F_m)均大于清水,F_v/F_m值小于清水;而台湾草正好相反。经差异显著性分析,中水培养对植物光合性能的影响与清水培养相比差异不显著(P>0.05)。中水水质能对4种绿地植物的形态、生理产生一定的影响,但与不同植物本身生物学特性有关。

Abstract: We studied the effects of reclaimed water on plant growth with the aim of extending the utilization of reclaimed water in Shenzhen. Growth, root development and photosynthetic traits were determined for four kinds of greenbelt plants, Axonopus affonis, Zoysia pacifica, Wedelia trilobata, and Duranta repens, cultured in reclaimed water and in cleaned water (CK). The heights of the greenbelt plants cultivated in reclaimed water for 30 d was lower than those cultivated in cleaned water (CK) but the root length was longer for up to 21 d and shorter after this. Root vigor was also less than those in the CK. However, there was no significant difference(P>0.05)between the plants cultivated in reclaimed water and cleaned water (CK). The chlorophyll content, initial fluorescence (F₀) and maximal fluorescence (F_m) of A. affonis and W. trilobata cultivated in reclaimed water for 30 d were greater than those under CK and F_v/F_m was less. However, the indexes of Z. pacifica showed a reverse change, possibly attributable to its biological traits. There was no significant difference between plants cultivated in reclaimed water and in cleaned water (CK) Although there were some negative effects of reclaimed water on the morphological, physiological modification, and photosynthetic traits of these plants.
