以高羊茅种子及幼苗为试材,研究了土壤中添加不同比例蟹壳粉对种子萌发和幼苗生长的影响,旨在找到适宜的蟹壳粉添加比例.结果表明,添加蟹壳粉对高羊茅的种子萌发和根系生长有一定的抑制作用,3％和5％蟹壳粉处理抑制作用更为显著;而蟹壳粉对高羊茅的地上生长和种子活力指数表现为低浓度促进、高浓度抑制.当蟹壳粉添加量为1％时,高羊茅株高生长最快,地上鲜重、干重和种子活力较对照分别提高了67.99％、70.14％和137.95％.隶属函数综合分析表明,蟹壳粉对高羊茅种子萌发和幼苗生长的影响效果由大到小的顺序为:1％、ck、3％、5％.因此,利用蟹壳粉作为草皮基质填充材料时,以1％的添加比例较为适宜.
Effect of Crab Shell Powder in Turf Medium on Seed Germination and Seedling Growth of Festuca arundinacea L.
In this paper,crab shell powder was mixed with soil in proportion to plant Festuca arundinacea L.The effect of crab shell powder with different proportions on seed germination and seedling growth of F.arundinacea was investigated.The results showed that the addition of crab shell powder inhibited seed germination and root growth,especially at the rates of 3％ and 5％.However,adding crab shell powder at low proportion (1％) enhanced seed vigor index and above ground biomass.When crab shell powder was added at 1％ mass ratio,plant height increased most rapidly.The shoot fresh weight,dry weight and seed vigor were increased by 76.99 ％,70.14％ and 137.95％,respectively,as compared to the control.The comprehensive analysis from subordinate function showed that the effect was ranked 1 ％,0％,3 ％,5％ from strong to weak.Therefore,using crab shell as filling material for turf substrate,low proportion (1％) is more appropriate.
