烤烟节水灌溉试验与示范

Experiments and Demonstrations on Water-saving Irrigation for Flue-cured Tobacco

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、67.95元/m³;灌溉投入产出比分别为68.5和56.6,而沟灌为8.9。因此,烟田应采用滴灌和喷灌方式而不宜再采用沟灌。

Abstract: 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.
