摘要 以“京研旱宝2号”黄瓜为试材,通过田间试验,对膜下地表和膜下浅埋2种滴灌形式对沙培黄瓜生长、品质及产量的影响进行了研究,以期获得种植沙培黄瓜最适宜的滴灌形式。结果表明:在黄瓜苗期,浅埋滴灌的植株生长状况与地表滴灌处理相比具有较大差异,浅埋滴灌处理一次灌水后10cm处的土壤含水率在一天时间内一直维持在较高阶段,其黄瓜苗期的最大株高、茎粗分别比地表滴灌提升30.8%和12.8%。;前、中、后期产量分别比地表滴灌提高27.6%、8.7%和24.1%,总产量比地表滴灌提高了10.9%;2种滴灌形式下黄瓜的干物质、维生素C含量之间无显著性差异,而浅埋滴灌比地表滴灌的水溶性糖含量提升28.6%。因此浅埋滴灌更有利于沙培黄瓜的生长。 Taking cucumber ‘Jingyan Hanbao No.2’ as material,surface and subsurface drip irrigation was used to search the effect of different irrigation methods on growth and yield of cucumber grown in sand culture by field trial in order to obtain the most suitable form of drip irrigation for cultivating sandy cucumber.The results showed that in the seeding stage,subsurface drip irrigation was better than the surface drip irrigation.Compared with the surface drip irrigation,the maximum plant height and stem diameter of subsurface drip irrigation increased by 30.8% and 12.8%,respectively.After irrigation,the sand moisture content of subsurface drip irrigation remained a relative high level.The yield of subsurface drip irrigation in the early stage,mid stage and later stage increased by 27.6%,8.7% and 24.1% respectively.The total yield increased by 10.9%.There was no significant difference in the contents of dry matter and vitamin C between the two drip irrigation methods.The water soluble sugar content of subsurface drip irrigation was 28.6%,higher than that of surface drip irrigation.So subsurface drip irrigation was more conducive to the growth of sandy cucumber.
