不同生产方式对地毯式网草皮质量的影响

Impacts of different procedures on quality of sod

以3种方式生产地毯式草皮,分别为:A栽培基质+无纺布+栽培基质+种子+尼龙网+栽培基质;B栽培基质+无纺布+栽培基质+种子+栽培基质;C栽培基质+河沙+栽培基质+种子+尼龙网+栽培基质,以期为地毯式草皮的规模化生产提供依据。结果表明,除地下植物量C处理显著大于A、B处理外(P<0.05),其余坪用性状指标不同处理间差异不显著。草皮强度C处理最大,B处理最小;草皮破损率B处理最大,A和C处理均为零;不同处理间草皮重量差异不显著。用灰色关联分析法对草皮质量进行综合评价,其优劣依次为C>A>B。

Three procedure treatments（A.base medium ＋ non-woven fabrics ＋ culture medium ＋ seeds ＋ nylon net ＋ base medium;B.base medium ＋ non-woven fabrics ＋ base medium ＋ seeds ＋ base medium;C.base medium ＋ river sands ＋ base medium ＋ seeds ＋ nylon net ＋ base medium）were used for sod production in Lanzhou.The results showed that the underground phytomass within 0 to 5 cm in Group C was higher than Group A and B,and no significant difference among rest groups.The strength of Group C was the highest and Group B was the lowest.The breakage rate of Group B was the highest,and it was zero for Group A and C.The difference of sod weight per unit volume was not significant among 3 groups.Based relational grey analysis,sod quality sequence was CAB.
