地膜覆盖是一项广泛应用的蔬菜栽培技术,但是在菠菜栽培中的应用报道还很少.山东高密等她的菜农将这一技术应用于春菠菜栽培,证明了该技术在菠菜栽培中的实用价值.本试验以杂交耐寒圆叶菠菜和美美两个菠菜品种为试材,研究了地膜覆盖对春菠菜的影响,以为该技术的推广应用和技术提升提供理论依据.结果表明:地膜覆盖后菠菜出芽提前7d以上,覆膜也促进了菠菜的早期生长,株高、叶长、叶宽、叶片长、叶柄长、叶数和叶片鲜重、叶柄鲜重、叶片干重、叶柄干重都显著增加;但是到收获时地膜覆盖的效果明显降低,与对照的差异不显著.讨论了可能的原因,适时揭膜可能是发挥覆膜效果的关键措施.覆膜后杂交耐寒圆叶菠菜叶片的蛋白质和可溶性糖含量显著提高,其他营养成分的含量在覆膜处理和对照之间差异不显著.
