查询词典 drainage canal

Var. pyramidalis is not positively correlated with ion concentration in growth environment, the capacity of selective absorption and transport of ions in Populus alba L. var. pyramidali under salt stress in drainage canal is higher than Populus alba L. var. pyramidal is of normal growth in irrigation canal. Under salt stress, the concentration of K(superscript +)、Na(superscript +) of roots and leave of Populus alba L. var. pyramidalis have changed, the concentration of K(superscript +) of roots and leave dropt the concentration of Na(superscript +) of roots markedly increased, the concentration of Ca(superscript 2+), Mg(superscript 2+) have slightly changed, the concentration of Ca(superscript 2+) of roots dropted, the concentration of Mg(superscript 2+) increased, the concentration of Ca(superscript 2+), Mg(superscript 2+) of leave increased.

主要结论为：新疆杨各器官的离子含量与生长环境中的离子浓度不存在正相关趋势；排渠盐胁迫下生长的新疆杨对离子选择吸收和运输的能力高于灌渠正常生长的新疆杨；盐胁迫下，新疆杨根和叶中K、Na的浓度发生了明显的变化，K浓度在根和叶中呈下降趋势，Na浓度在根中明显增加，根和叶中Ca(上标 2+)、Mg(上标 2+)浓度的变化趋势略缓，根中Ca(上标 2+)浓度下降，Mg(上标 2+)浓度增加，叶中Ca(上标 2+)、Mg(上标 2+)浓度有所上升。

Result showed that, with the controlled facility, the water storage is about 19×10^3 m^3/km of in the main drainage canal, the groundwater table in farmland is raise about 0.3 to 0.5 m and the crop water use is increased about 50 to 80 mm comparing with the non controlled main drainage canal.

结果表明，单位长度大沟年调蓄水量为1.9×10^4立方公尺/km左右，其影响范围内的农田地下水位较无控制大沟平均抬高约0.3~0.5 m，每年可增加作物对地下水的直接利用量50~80 mm，区域年农田水资源调控总量110 mm左右，约占当地年均降雨量的13%；只要控制合理、管理得当，不会因此而影响排水系统对农田涝渍的有效控制或降低原有排水工程的除涝降渍标准。
