| 摘 要： | 为了研究水份对白肋烟根系发育及成活率的影响,采用田间试验研究手段,设置5种不同的浇灌方式,通过对土壤含水量、土壤温度、新根数、心叶大小、成活率等进行比较研究,定量地描述了水份与根系生长之间的动态关系。结果表明:处理3土壤水份含量较高,夜间地温较高,移栽后不萎蔫,亩产值和亩产量最高,原烟外观质量颜色近红黄,身份适中,结构疏松,光泽鲜明,综合表现较好。其次是处理5。

| Abstract: | In order to study the effects of watering on burley tobacco's root development and survival rate, five watering treatments were carried out through the field experiments. By the content of soil water, soil temperature, the number of new root and so on, the study describes quantitatively the relationships between soil water and root growth. The results showed that the treatment 3 had better comprehensive performances with higher soil water content and night temperature, no wilting after transplanting, the highest output value and yield, high qualities of leaf appearance, and coordinated chemical components. The treatment 5 was the second. |
