【摘要】 采用人工控水的方法研究了不同土壤水分对烤烟生长和产质量的影响。结果表明,烤烟伸根期、旺长期、成熟期土壤相对含水率分别为60%、80%和70%时,烤烟农艺性状和产质量最好,土壤相对含水率升高或者降低均对烤烟的产质量有影响。维持烟田土壤含水率在60%~80%~70%需供水161 kg/株,伸根期、旺长期和成熟期分别占灌溉总量的19.3%、38.5%和42.2%。更多还原

【Abstract】 The effects of soil moisture on growth,yield and quality of flue-cured tobacco were studied under artificial irrigation conditions.The results showed that the soil moisture content with 60% at root extending stage,80% at faster growing stage and 70% at maturing stage were the best for the growth,yield and quality of tobacco.161 kg water was required for each plant to keep the soil water content from 60% to 80% and 70%.Appropriate water consumption at the root extending stage,vigorous growing stage and maturing stage were 19.3%,38.5% and 42.2% respectively.更多还原
