摘  要：
通过设置不同体积比例的泡沫与土壤混合物,进行沿阶草的栽培,并测定各组沿阶草的生长指标与土壤酶活性。结果表明:在土壤中加入(占混合物总体积)10%的泡沫时,沿阶草的根长、株高、单株鲜干质量等各项生长、生理指标均较不添加泡沫的对照组有显著增加;而土壤过氧化氢酶活性在土壤含20%泡沫处理时达最大值,为0.144U/g,其次是在含10%泡沫时,酶活性为0.119U/g,均与对照组差异明显;脲酶活性在土壤含50%泡沫处理时达最大值,为0.367U/g,其次是在土壤含10%泡沫处理时,为0.353U/g,均与对照组差异明显。研究表明,在泡沫所占体积为10%时沿阶草生长状况更好且土壤酶活性较高。

摘  要：
By designing different volume ratio of the mixture of foam and soil,Ophiopogon japonicus was cultivated to detect the growth indexes and soil enzyme activity.The results indicated that serval indexes,i.e.root length,plant height,fresh weight,dry weight,and the contents of Chlorophyll a,Chlorophyll b and Carotinoid,increased when the volume ratio of foam was 10% in soil.They had significant differences with the control group.Catalase activity had the maximum value(0.144U/g) at the ratio of 20% of foam,and it had sub-maximum value(0.119U/g) at the ratio of 10%,they both had significant differences with the control group.Urease activity had the maximum value(0.367U/g) at the ratio of 50%,and had the sub-maximum value(0.353U/g)at 10%,they both had significant differences with the control group.The study revealed that theO.japonicus grows better and soil enzymes have greater activity when the ratio of foam is 10%.
