摘要：

采用一年生黑麦草（Lolium multiflorum）、狗牙根（Cynodon dactylon）及匍匐剪股颖（Agrodtis stolonifera）等3种草坪草和青绿苔草（Carex leucochlora）进行混播种植，通过综合评价的方法找到适合与青绿苔草进行混播的草种，辅助其快速成坪并制作草皮卷。控制青绿苔草播量（6 g·m-2，12 g·m-2），按3：1，6：1，10：1的比例加入上述3种草坪草种子混播。结果表明：青绿苔草播量为6 g·m-2时混播可增加青绿苔草株高；与狗牙根6 g·m-2混播时可增加青绿苔草的根长；与黑麦草12 g·m-2混播时草皮卷起卷难度最低且完整度高。通过各处理草皮卷质量的综合评价表明，最优的2个混播组合分别是6 g·m-2播量6：1混播匍匐剪股颖（Tr15）和12 g·m-2播量10：1混播匍匐剪股颖（Tr9）。

Abstract:

Carex leucochlora wasmixed with three turf grasses, annual ryegrass (Lolium multiflorum), Cynodon dacty and creeping bentgrass (Agrodtis stolonifera). The mixture sowing experiment was conducted to find the appropriate turf grass mixed with Carex leucochlora under the method of comprehensive evaluation, and also to fast sod production. Carex leucochlora was mixed with each of the wthree kinds of turf grasses at the ratio of 3:1, 6:1 and 10:1. The seeding rate of Carex leucochlora was set at 6 g·m-2 and 12 g·m-2, respectively. The results showed that the height of Carex leucochlora increased at 6 g·m-2 under mixture sowing; while root length increased with Cynodon dactylon at mixture sowing rate of 6 g·m-2. For ryegrass, rate at 12 g·m-2 had a high degree of turf roll integrity and the sod is easier to harvest. Under comprehensive evaluation, the highest two mixture seeding combinations were mixture with creeping bentgrass at the sowing rate of 6:1 at 6 g·m-2 (Tr15) and 10:1 at 12 g·m-2 of Carex leucochlora (Tr9) among the treatments.
