对3种暖季型草坪草假俭草(Eremochloa ophiuroides)、结缕草(Zoysia sinica)和沟叶结缕草(Zoysiamatrella)在土壤盐分胁迫下的一些生理指标的变化进行了初步研究。结果表明,在草坪草适应范围之内,根系活力和蛋白质含量呈先升后降的趋势,如超过忍受范围则持续下降;随盐分胁迫强度的增加和胁迫时间的延长,草坪草叶片的WSD上升,脯氮酸含量均表现为先升后降的趋势,但因胁迫程度和草种的不同,其峰值和下降幅度有较大差异。各项生理指标变化的趋势因草种的不同而有较大的差异,与其耐盐性有关,可以作为判定草坪草抗盐能力的评定依据。 The changes of some physiological indexes of soil under three kinds of warm season turfgrass (Eremochloa ophiuroides, Zoysia sinica and Zoysia matrella) were studied. The results showed that within the adaptive range of turfgrasses, the root activity and protein content tended to increase first and then decrease, for example, they continued to decrease over the tolerable range. With the increase of salt stress and the prolongation of stress time, the WSD of turfgrass increased , The content of proline nitrogen showed the trend of first rising and then decreasing. However, due to the different degree of stress and the difference of grass species, the peak value and the decreasing amplitude of the content were different. The trend of the change of physiological index is quite different due to different grass species, which is related to its salt tolerance and can be used as the basis for judging salt tolerance of turfgrass.
