灌渠

Since 1962 the lake was polluted by wastewater of a chemical plant which manufactured parathion, malathion, dimethaote and BHC.

以解决在氧化塘沿岸的东西排灌渠12.8公里两岸人民的灌溉水和饮用水的污染问题。

To ward off an outbreak, Davis says, the government would have to prevent the use of night soil as fertilizer, build cement irrigation ditches, and ensure area villagers access to clean water.

为避免血吸虫病的爆发，Davis说，政府应避免使用粪便作为肥料，修建水泥灌渠，并确保当地居民接触干净的水。

At that time, he worked as an official term, sympathetic to their needs, to see the wind does not tend to transfer the rain, the drought there is usually a threat to people near the city and well water too salty brine, it should not drink, we can not irrigate fields, and he from the county seat from North 30 Whalley's "drum reactor Stephen" attracted cool spring water, 12 irrigation channels opened, the majority of irrigated land along the way, a small number of flows to the provincial governor at the time of the "teeth City", from the back ofzhou ya after flowing into the suburban markets and to address the the people of rural drinking water and irrigation problems.

当时他为官一任，体察民情，看到风不调雨不顺，常常有旱灾威胁百姓，城池附近，井水又多卤咸，既不能饮，又不可浇灌田园，于是他从距县城北30华里的"鼓堆泉"引来清凉的泉水，开了12道灌渠，大部分浇灌沿途田地，小部分流入当时刺史的"牙城"，从州衙的后面经过，流入街市和城郊，解决了人民饮水和灌溉田园的问题。

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。

Taking Populus alba L. var. pyramidalis in irrigation canal and drainage canal as an object of study, absorption, transport and distribution characters of K(superscript +), Na(superscript +), Ca(superscript 2+), Mg(superscript 2+) in Populus alba L.

论文以灌渠和排渠两种生境上的新疆杨为对象，研究自然生长状况下新疆杨Populus alba L。

Suddenly he saw water pouring out of a hole in the wall of an irrigation ditch.

他突然看到水从灌渠边上的一个洞里大量流出来。
