塑料大棚内不同地膜覆盖对草莓生长及生理特性的影响

摘要

为了明确不同地膜覆盖对草莓生长的影响,在塑料砖棚和土棚同时进行不同地膜覆盖试验,以黑白相间地膜、双色地膜(上层为银灰色,下层为黑色)与黑色地膜覆盖进行了大棚草莓生长的对比试验.结果表明,草莓种植在塑料砖棚内采用地膜覆盖的多次生理指标测试结果都要优于在塑料土棚内采用地膜覆盖的测试结果;黑白相间地膜覆盖对土温影响较大,对草莓植株根系活力影响显著;双色地膜覆盖对草莓色泽有显著影响;黑色地膜覆盖对草莓生理指标有显著影响.不同地膜覆盖对草莓生长因素影响不尽相同,可根据塑料大棚及设施和草莓品种特点选择相适宜的地膜覆盖方式,从而达到最佳配置,进一步提高草莓的产量及品质.%Different fibler mulching film experiments were carried out in plastic brick shed and soil shed at the same time,to research the effect of mulching film on growth of strawberry.The experiment of strawberry growth in greenhouse was tesed,using the black-white fibler film and double color fibler film (the upper layer was silver grey,the lower layer was black) compared with the black plastic mulching film.The results showed that stawberry grown in the plastic brick shed with mulching film was better than the plastic solid shed through multiple physiological index tests.The white-black mulching film had a very significant correlation with the soil temprature and root activety.The double color fibler mulching film and black fibler mulching film had a great influence on the strawberrycolor and the physiological index,respectively.Differeent fibler mulching film had a different influence on the growth of strawberry,which depented on the greenhouse stucture type and strawberry varieties to achieve the optimum reshlts,and further improved the yield and quality of strawberry.
