以北京市常见冷季型草坪草多年生黑麦草、高羊茅和草地早熟禾为对象,借助于CAT、POD、MDA、脯氨酸、叶绿素等生理指标,采用室内盆栽的方法研究再生水灌溉下冷季型草坪草的生理反应,及各种生理指标与基质盐分累积的关系,对3种草坪草2种水源灌溉生理适宜性进行综合评价。结果表明:再生水中盐分含量刺激多年生黑麦草和高羊茅体内保护型酶活性保持较高水平,从而保持较强的生理优势,再生水作用使得草地早熟禾生长发育受阻,但盐分不是造成生长受阻的主导因素。在盆栽条件下,不同草坪草对不同灌溉水源生长适宜性由强至弱依次为再生水高羊茅,自来水高羊茅,自来水草地早熟禾,再生水多年生黑麦草,自来水多年生黑麦草,再生水草地早熟禾。
Taking the cold season turfgrass perennial ryegrass, tall fescue and Kentucky bluegrass in Beijing as objects, with the aid of CAT, POD, MDA, proline and chlorophyll and other physiological indexes, the indoor pot experiment was used to study the effects of reclaimed water irrigation The physiological responses of the turfgrasses and the relationship between various physiological indices and the accumulation of matrix salt were evaluated. The physiological adaptability of two kinds of turfgrasses was evaluated comprehensively. The results showed that the salt content in reclaimed water stimulated the activities of protective enzymes in perennial ryegrass and tall fescue to maintain a high level of physiological activity, thus maintaining a strong physiological advantage. The effects of reclaimed water on the growth and development of the meadow grass were hampered, however, The dominant factor. Under potted condition, the adaptability of different turf grasses to different irrigation water sources was from high to low, followed by high-forage grass of reclaimed water, tall fescue of tap water, Kentucky bluegrass of tap water, perennial ryegrass of reclaimed water, perennial ryegrass of tap water, .
