摘要:
醉马草自身携带Epichlo?内生真菌,具有一定的抗虫性和驱鸟性,其作为西北地区机场草坪绿化驱鸟草种具有极大潜力。为实现醉马草作为一种驱鸟草应用于机场草坪,本试验对醉马草草坪栽培技术进行研究,探究植物生长调节剂(0.136%赤·吲乙·芸苔可湿性粉剂)浸种和不同材料覆盖苗期草坪以及二者结合对醉马草坪用性状的影响。本试验在醉马草出苗期和成坪期对出苗率、成坪速度、生长速度、密度、盖度、色泽、质地、均一性、草层高度等指标进行测定,并对草坪进行综合评价。结果显示,无纺布覆盖、生长调节剂浸种+无纺布覆盖处理醉马草出苗早、成坪速度较快;生长调节剂浸种+无纺布覆盖处理下成坪后醉马草生长速度较慢、草坪密度、叶绿素含量和均一性均高于对照和其他处理;无纺布覆盖和生长调节剂浸种+秸秆覆盖处理下草坪盖度较高。综合评价结果显示,生长调节剂浸种+无纺布覆盖处理下醉马草草坪的综合质量最好,是最佳的栽培措施,适合应用推广。
