摘要: 以不同淋洗方式处理后的生活垃圾堆肥为基质进行草坪植物培植,研究了高羊茅的生理生态响应。结果表明,淋洗处理堆肥中高羊茅的发芽率及株高等生长指标均优于未淋洗的原堆肥对照组,其中水肥淋洗比例为1∶1的处理中,高羊茅的最大发芽率比对照提高89.6%。通过对超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)3种保护酶的活性及脯氨酸和丙二醛(MDA)含量等指标的测定可以看出,经淋洗处理后的堆肥基质对草坪植物的胁迫程度均小于原堆肥,更有利于草坪植物的正常生长。综合高羊茅生长指标及生理指标来考虑,堆肥处理的最佳淋洗比例为水∶堆肥的质量比为2∶1。

Abstract: Festuca arundinacea L. was planted in municipal solid waste (MSW) compost which was leached by different amount of water. Seed germination and physio-ecological indices were investigated. The results showed that F.arundinacea in the leached compost was better than in the control(pure compost without leaching) through the growth index. In the treatment of 1∶1 leaching proportion, the maximum germination rate increased 89.6% as compared with the control. The determination of the activity of protective enzymes(SOD, POD, CAT), the content of proline and the accumulation of MDA indicated that the stress of compost after leaching was less than pure compost without leaching, and the leached compost was more favorable for turf growth. Considering of growth and physiological indices of F.arundinacea, the optimum proportion for compost leaching was the mass ratio of water to compost=2∶1.

Key words: leaching, MSW compost, Festuca arundinacea L., malondialdehyde, proline, protective enzyme
