摘　　要：以西瓜品种"金陇5号"为试材,在宁夏中部干旱带开展了旱地地膜西瓜不同播期、种植方式研究,分析了不同播期与种植方式对旱地西瓜产量及土壤水分利用的影响。结果表明:4月15日采用暗窝播种方式西瓜生长状况、产量、产值、纯收入及土壤水分利用效率方面均优于其它处理,较4月25日、5月10日播种的产量分别增产4.8%和28.0%,纯收入增加6 700.02元/hm2和19 604.31元/hm2,水分利用效率提高23.1%、54.4%,抗旱节水、增产增收的效果明显;说明当地旱地西瓜适宜的播种时期为4月中旬,种植方式采用先播种后覆膜的暗窝播种。Taking watermelon variety‘Jin long 5＇as tested material,effects of different sowing date and planting method yield and soil water use of dry film mulching watermelon in middle arid belt of Ningxia were studied and analyzed.The results showed that the treatment with the dark nest sowing method on April 15 th was superior to other treatments on the growth status,yield,production value,net income and the use efficiency of soil water.The yield of April 15 thincreased by4.8%and 28.0%,net income increased by 6 700.02RMB/hm2 and 19 604.31RMB/hm2,and the water use efficiency increased by 23.1%and 54.4%compared with those of April 25 th and May 10 th,respectively.The results indicated that effect on drought resistance,water saving,increasing production and income.Meanwhile was obvious,the prefect time was in the middle of April and the best planting method was the dark nest sowing which sowing after film mulching in middle arid belt of Ningxia.
