摘要
采用盆栽试验法,研究了江西烟区3种类型土壤不同土壤水分含量对烤烟K326生长发育的影响。结果表明,土壤水分含量对K326的生长发育影响明显。与水分胁迫相比,适宜水平土壤水分(旺长期土壤相对含水量80%、成熟期土壤相对含水量70%)可保证烟株正常生长发育。
Taking three different types of soil as experimental material,the effects of water content on growth of flue-cured tobacco were studied by the method of pot culturing.The results showed that water content had significant effect on the growth of flue-cured tobacco K326.Compared with water stress,the optimum soil relative capacity maintained separately at 80%,70% may guarantee the normal growth of flue-cured tobacco during peak period and mature period.
