一种新型边坡防护性无土栽培草坪基质的研究

设置3种不同麦糠腐熟处理和4个施肥水平,测定了腐熟麦糠的理化指标和黑麦草苗后30d的各项生物学指标。试验结果表明,各腐熟处理后基质的各项理化指标符合优良无土栽培草坪基质的基本要求,可以用作草坪无土栽培基质;腐熟污泥处理后的基质优于其它处理,可以显著提高黑麦草的生长速度,白糖处理和空白处理间无显著性差异;在所有的处理中,当出苗率高于60%时,苗后30d的草坪即可成卷。该试验结果为将麦糠基质草坪应用于边坡防护等水土保持工程措施奠定基础。

A New Matrix for Soilless Cultivation of Lawn in Slop Protection

The purpose of the study was to demonstrate the feasibility of bran to be the matrix of soilless-cultured lawn through measuring physiochemical indexes of matured bran and biological indexes of lawn.A three-level bran maturing experiment with four levels of fertilization was carried out.The biological indexes of ryegrass lawn were measured 30 days after seedling emergence.Results show that the physical and chemical indexes of matured bran meet the basic requirements of lawn cultivation and it can be used as a lawn matrix.The addition of sludge for maturing is more effective than the addition of sugar and check,which can significantly increase ryegrass growth rate.When the rate of seedling emergence is higher than 60%,the lawn is coiled.The study provides some basic data applied to soil and water conservation and slope protection.
