In order to test the possibility for recycling use of aged refuse as sward soil, the study determined the responses of Lolium perenne L. (perennial ryegrass), Festuca arundinacea (tall fescue), and Poa annua (annual bluegrass) to its leaching. The growth of three seedlings was significantly inhibited after treatment, especially for longer treatment duration and higher concentration leaching; however, with the better growth and chlorophyll content for shorter time and lower concentration, tall fescue was more tolerant to the stress. Afterwards, several physiological responses of tall fescue were determined. For shorter treatment duration, antioxidant enzyme activities remained unchanged, and no obvious oxidative damage was observed. Prolonging exposure time, lipid peroxidation and protein oxidation occurred after treatment of higher concentration leaching, accompanying by changes of antioxidant status. It implicates that it is possible for using aged refuse as sward soil, and the critical point focused on selecting tolerant grass and controlling exposure condition.
为了测试老化垃圾作为草坪土壤再利用的可能性，本研究测定了多年生黑麦草（Lolium perenne L.）、高羊茅（Festuca arundinacea）和草地早熟禾（Poa annua）对其淋溶的反应。三种幼苗的生长在处理后受到明显抑制，尤其是处理时间更长和浓度更高的淋溶；然而，高羊茅在较短时间和较低浓度下生长和叶绿素含量更好，对胁迫的耐受性更强。之后，测定了高羊茅的几项生理反应。对于较短的处理时间，抗氧化酶活性保持不变，没有观察到明显的氧化损伤。延长暴露时间后，高浓度淋溶处理后发生脂质过氧化和蛋白质氧化，同时抗氧化状态发生变化。这表明使用老化垃圾作为草坪土壤是可行的，关键在于选择耐受草种和控制暴露条件。
