利用结缕草草屑生产无土草毯基质配方研究

摘要

Four matrix recipes were used in the experiment with the main substrate of grass zoysia Lanyin No.3.The effects of different matrix formulations on lawn quality were studied for determining the best recipe.The physical and chemical properties of each treated soil-free turf and the properties of turf grass were analyzed.The results showed that:D treatment (Lanyin No.3 grass + 10％ rape cake + 5％ perlite) was the best in the four treatments,and its available nutrient was abundant and balance,its void ratio,volume-weight and organic content were good.There were no significant differences in green blanket green index,homogeneity,NDVI index among the four treatments.Comprehensive assessment of turf density,texture,the characteristics of ground and underground part of the lawn,the treatment D was best soil-free turf matrix.%以‘兰引3号’结缕草草屑为无土草毯的主要基质,设计4种不同基质配方处理(A.兰引3号草屑;B.草屑+5％珍珠岩;C.草屑+5％泥炭土+5％珍珠岩;D.草屑+10％菜枯+5％珍珠岩),研究不同基质配方对草坪质量的影响,以确定最适配方.通过对各处理无土草毯的理化性状及草坪坪用性状分析测定,结果表明:D处理基质容重适宜、孔隙度较为理想、有机质含量高、速效养分含量最丰富且均衡,理化性质良好,成坪速度、密度最优.草毯盖度、均一性和草坪颜色在4个处理中无明显差异.D、B和C处理的地上生物量之间差异不明显,但都显著高于A处理.D处理的地下生物量显著高于其它处理,B、C和A处理之间差异不明显.4个处理基质均为轻质材料,草毯重量显著低于有土草皮.综合评价各个处理的理化性状和草毯坪用性状,D处理是最理想的无土草毯基质配方.
