新型生态草皮卷生产专用基质研究

Special-purpose Matrix for Production of New Ecological Turf Roll

[目的]探讨适合不同类型草皮卷生产的专用基质。[方法]研究不同的基质体积配比对多年生黑麦草、改良型狗牙根、高羊茅+多年生黑麦草组合地上部分分蘖数、地下部分根长和根数、根冠比、成毯性等的影响。[结果]狗牙根草皮生产基质以废菌棒∶园土∶堆肥土=3∶4∶3为宜,多年生黑麦草以炭化谷糠∶园土∶泥碳=3∶4∶3最好,高羊茅+多年生黑麦草以秸秆∶园土∶堆肥土∶煤渣=2∶3∶3∶2为宜,可作为新型生态草皮卷生产的专用基质。[结论]试验结果为生态草皮卷规模化生产提供了理论依据。

[Objective] The aim was to explore special-purpose matrix for production of new ecological turf roll. [Method]We studied effects of different volume ratios of matrix on the tiller number of aboveground part,root length of underground part,root number,the ratio of root to shoot and carpet forming of perennial ryegrass,improved bermudagrass,and the combination of tall fescue and perennial ryegrass. [Result]The bermudagrass turf production matrix with culture waste of edible fungi∶ garden soil∶ compost = 3∶ 4∶ 3 was appropriate,perennial ryegrass production matrix with carbonized chaff∶ garden soil∶ peat = 3∶ 4∶ 3 was the best,and the combination of tall fescue and perennial ryegrass production matrix with straw∶ garden soil∶ compost∶ cinders = 2 ∶ 3 ∶ 3 ∶ 2 was appropriate,which could be used as special-purpose matrix for the production of new ecological turf roll. [Conclusion] The results provide theoretical basis for the large-scale production of ecological turf roll.
