采用 4因素 3水平正交组合试验 ,对早熟禾、高羊茅、多年生黑麦草不同播种量、种间配合比例进行了混播试验 ,观测成坪期、成坪时的成坪率以及当年和 3年的盖度 ,并对草坪草质进行综合评价 ,结果表明 :影响成坪速度、保存盖度的主要因素是草种的配合比例 ,影响草坪质量的主要因素是早熟禾种间配合比值。具体表现为高羊茅比值高成坪速度快 ,保存盖度大 ;早熟禾比值大 ,草坪质量好 ,表现性状稳定。提出以播种量 1 5 g/m2 ,早熟禾、高羊茅、黑麦草重量比值为 5∶ 3∶ 2的效果较为理想 ,重要景区草坪可适当增加早熟禾比例 ,以增强草坪的观赏效果。
The orthogonal experiment of 4 factors and 3 levels was used to study the different sowing rates and interspecific combinations of Kentucky bluegrass, Tall fescue and perennial ryegrass. The results showed that the main factor affecting the speed and preservation coverage was the proportion of grass species. The main factor influencing the quality of turfgrass was the ratio of the species between different species. The results showed that the ratio of tall fescue was higher than that of high foraging, and the storage coverage was high. The ratio of Kentucky bluegrass was large, the quality of turf was good, and the performance was stable. Proposed sowing rate of 15 g / m2, bluegrass, tall fescue, ryegrass weight ratio of 5: 3: 2 is the ideal effect, important scenic lawn can increase the proportion of Kentucky bluegrass in order to enhance the lawn ornamental effect.
