在半干旱黄土丘陵区，采用CIRAS-2型光合作用系统，在不同土壤水分条件下，对2年生杠柳的净光合速率、蒸腾速率、叶片水分利用效率、气孔导度和胞间CO2浓度等叶片气体交换参数的日变化进行了研究。

The reason for this was,first,that the Nile brought water to a rainless desert and,second,that once a year,the river overflowed it anks,leaving,as the water went back,a new layer of fertile soil.

其中的原因首先是尼罗河为少雨的沙漠带来水源，其次，每一年，尼罗河都会泛滥，当水退会河中时，留下新一层肥沃的土地。

The reason for this was,first,that the Nile brought water to a rainless desert and,second,that once a year,the river overflowed it anks,leaving,as the water went back,a new layer of fertile soil.

这其中有两个原因：其一，尼罗河为干旱的沙漠带来了水源；其二，每年，尼罗河水都会溢出河岸，流走；水再次退回河中，肥沃的土地形成了。

In accordance with the prevention of soil salination and water-saving irrigation in autumn in Inner Mongolia Hetao irrigation district, the reasonable water-saving irrigation scheme in autumn was quantificationally established by using SHAW model in theory, which aimed at the different salinized soils.

根据内蒙古河套灌区秋浇节水与土壤盐渍化防治的需要，利用SHAW模型模拟确定了不同盐渍化土壤合理的秋浇节水灌溉制度。
