在沈阳师范大学实验园内将结缕草Zoysia japonica茎段分别栽植在腐殖质(A1)、建筑残土(A2)、表土被移除土壤(A3)、沙(A4)4种土壤基质上,研究土壤基质对结缕草净光合速率及生长的影响.结果表明,结缕草的净光合速率和大部分的生长指标均为A1＞A4＞A2＞A3.腐殖质基质有效促进了结缕草的生长,各生长指标与其他处理间差异显著.其他3个处理之间差异不显著(P>0.05).结缕草在基质A4上的生长指标优于基质A2和A3,说明结缕草耐贫瘠,而土壤结构的破坏不利于其生长.

Stems of Zoysia japonica were separately planted on the four matrixes such as humus (A1), residual soil after construction (A2), soil with surface layer removed (A3) and sand (A4) in the experimental garden of Shenyang Normal University. The effect of soil matrixes on net photosynthetic rate and growth of Z. japonica were measured. The results showed that the sequence of net photosynthetic rate and most of the measured growth indexes was A1＞A4＞A2＞A3. The high level nutrient of humus promoted the growth of Z. japonica greatly, and the growth indexes showed significant difference compared to other treatments (P<0.01). The differences among A2, A3 and A4 were not significant (P>0.05). The growth indexes of A4 better than A2 and A3, so the destroyed structure of soil was an unfavorable factor to influence the growth of Z. japonica.
