摘　　要：进行了不同灌水方式对烟田土壤性状、烤烟农艺性状和经济性状影响的试验。结果表明 ,滴灌、喷灌对烟田的土壤结构、烤烟的生长发育和产、质等有显著影响。采用滴灌和喷灌节水效果显著 ,灌水产出分别达 82 .19元 m3 、6 7.95元 m3 ;灌溉投入产出比分别为 6 8.5和 5 6 .6 ,而沟灌为 8.9。因此 。The experiments on effects of different irrigation methods on characteristics of soil, agronomic and economic characteristics of flue-cured tobacco were conducted. The results showed that: 1) drip and spray irrigation had significant effects on soil structure and growth, development, yields and quality of flue-cured tobacco, and showed significant water-saving effects; 2) input-output ratios of drip, spray and furrow irrigation were 68.5, 56.6 and 8.9 respectively. Therefore, drip and spray irrigation, rather than furrow irrigation, should be used in tobacco fields.
