摘　　要：冀西北坝上地区近年来喜凉蔬菜面积扩大,地下水位严重下降,为了减少地下用水量并提高降水资源利用效率,研究了不同种植方式对萝卜产量和水分利用效率的影响。结果表明,在萝卜生长前期地膜覆盖处理的保墒作用明显,可使0~60cm土壤含水量较不覆膜处理增加3.16~15.84mm。同时,覆盖地膜可使萝卜生长提前,并在整个生长期节约用水29.38~30.15mm。平畦覆膜处理的水分利用效率比平畦不覆膜处理提高34.4%,但其肉质根畸形率高达25.64%,产量、质量和产值均低于高畦覆膜;高畦覆膜处理的产量和水分利用效率比高畦不覆膜分别提高了10.1%和21.3%。高畦覆膜的各种效应优于平畦,是该区水分高效利用的关键与适用技术。The increase of areas of cool vegetable led to the decrease of water table,to reduce the use of water under-ground and make full use of local rainfall,the effect of planting pattern on yield and water use efficiency of radish was studied.The results showed that plastic film mulch had remarkable function of increasing soil moisture conservation during early radish growth period,3.16-15.84 mm higher than CK without plastic film in 0-60 cm soil,which not only advanced radish growth but also saved water 29.38-30.15 mm during whole radish growth period;water use efficiency of level farmland radish under plastic film mulch increased by 34.4%than CK,but the abnormality root rate was high with 25.64%,and the yield,quality and production value of radish were lower than high farmland under plastic film mulch;yield and water use efficiency of high farmland under plastic film mulch increased by 10.1% and 21.3%than CK,respectively.High farmland under plastic film mulch excelled level farmland in all effects,which was a key and suitable technology for efficient use of water.
