摘要： 在我国北方地区,为使草坪在春季提前返青,延长草坪全年绿期,并最终使得草皮生产率得以提高,以及延长高尔夫球场的营运时间,获得很多经济收益。通过在3个不同时间用聚乙烯塑料薄膜和无纺布对草坪进行覆盖,与无覆盖处理的草坪相比较,研究冬季地膜覆盖对草坪返青的影响,并得出最佳覆盖材质和覆盖时间。结果表明:覆盖处理的草坪比无覆盖处理的草坪提前1个月开始返青;揭膜时,12月15日用塑料薄膜覆盖的草坪,以及1月9日用塑料薄膜覆盖和无纺布覆盖的草坪盖度达到80%,与无覆盖处理相较提前30d完成了返青;揭膜时,用塑料薄膜覆盖的草坪已完成返青,且盖度达到了足球场和草皮质量的二级水平,可直接用于实际应用。覆盖期间,无覆盖处理在2月中旬达到完全枯黄状态;而覆盖的草坪在整个覆盖期内,并未完全枯黄。1月9日用塑料薄膜覆盖对草坪盖度的影响最佳,可使草坪提前返青,在冬季也能保有一定绿色,最终延长了草坪绿期。

Abstract: Mulch is one of the techniques which can promote the sustained growth of plants under the unfavorable environment and then this kind of technique achieves good quality results.The effect of the winter protection on prolong green period of the turf,and the best way to mulch,were studied through mulching with polyethylene(PE) and non-woven fabrics in three difference period in winter,compared with the non-mulch turf.The results showed that protective covers,used by PE in 15 th Dec.and in 9 th Jan.,was an increase,by about 30 days,in the rate of the green-up process compared with non-mulch.And in 26 th Mar.,these coverage of the turf which mulched with PE in 15 th Dec.and in 9 th Jan.,came up to the standard of the sport′s lawn and the production of the sod.The turf with these protective covers kept green and did not turning yellow during winter.It could be concluded that the covers used by PE in 9th Jan.was the best for prolonging turf green period.
