| 摘 要： | 采用大田试验研究了灌水和钾肥用量对烤烟干物质积累及养分吸收的影响。结果表明,灌水和施用钾肥均可以促进烤烟干物质积累和养分吸收,显著提高叶片氮、钾含量。其中,灌水对增进烤烟干物质积累和烟株吸收磷素的效应大于施用钾肥,而施用钾肥对增加烤烟吸收氮素和钾素的作用大于灌水,水钾耦合对烤烟干物质积累和烟株养分吸收均有不同程度的正互作效应。

| Abstract: | A field experiment was conducted to study the effects of irrigation and potassium rate on dry matter accumulation in and nutrient uptake of flue-cured tobacco.The results showed that either potassium rate or irrigation could improve dry matter accumulation and nutrients uptake,and significantly increase the concentration of nitrogen and potassium in leaves.Irrigation promoted dry matter accumulation and phosphorus uptake more obviously than did potassium rate,while potassium rate increased the uptake of nit... |
