以‘兰引Ⅲ号’结缕草为试材,进行无土栽培试验,研究了4种不同的隔离层(遮阳网、无纺布、地膜、砖块)材料对‘兰引Ⅲ号’结缕草草皮质量的影响;通过定期测定草坪盖度、密度、颜色及成坪后的草皮强度,以便筛选出适合的无土草皮生产的隔离材料。结果表明:建植70d后遮阳网隔离层草皮的盖度为92.78%、100cm2密度为81.34枝、色泽为6.67,均高于其余隔离层材料,生长过程整体表现为遮阳网>砖块>无纺布>地膜;砖块的草皮强度为5.98kg,显著高于其余3种隔离层材料,但砖块隔离层与遮阳网隔离层相比建设成本太大。综合考虑,认为遮阳网隔离层比较适合‘兰引Ⅲ号’结缕草无土草皮的生产,而地膜的排水透气能力较差,不适宜作为‘兰引Ⅲ号’结缕草无土草皮生产的隔离层材料。
Taking “Zilan Ⅲ” Zoysiagrass as test material, soilless culture experiment was carried out to study the effect of four different isolation layers (shading net, non-woven fabric, plastic film and brick) The effects of turfgrass quality on turfgrass quality were determined by regularly measuring turf coverage, density, color and turfgrass strength after turfgrass so as to screen suitable isolation materials for soilless turfgrass production. The results showed that after 70 days of planting, the cover of the sunscreen net was 92.78% and the density of 100cm2 was 81.34 with the color of 6.67, which was higher than that of the other materials. The growth process showed as follows: shade net> brick> Cloth> mulch; the turf strength of the brick is 5.98 kg, which is significantly higher than the other three kinds of material, but the cost of the bricks is much higher than that of the shade net. Considering synthetically, it is considered that the sunscreen network isolation layer is more suitable for the production of soilless turf of ’Zanyue III’ Zoysia glyphosate, while the plastic membrane has poor drainage and gas permeability and is not suitable for production of ’Silage III’ Isolation material.
