| 摘 要： | 基于3种增氧滴灌方式,研究了增氧滴灌对烟草农艺性状的影响。结果表明,化学溶氧滴灌方式总节水效果和产量增产效果均比机械加气滴灌好。机械加气滴灌可使烟草根系活力达到最优,根系体积扩大,不定根及细根量增多,总耗水量增加;而化学溶氧加气滴灌根系的发育要比冠部的发育慢,可节约部分水。

| Abstract: | Based on three different drip irrigations,the effects of aerobic irrigations on agronomic traits were studied.The results showed that chemical oxygen irrigation could save water better and improve yield faster compared to mechanical aerobic irrigation.Tobacco root optimal vigor appeared in the mechanical aerobic irrigation while adventitious root,root volume and the total water consumption increased.Chemical oxygen irrigation could save water duing to root growth lower than cap. |
