Shallow groundwater by capillary force into the vadose zone soil layer , replenish soil moisture becomes . Namken etc. with lysimeter study found that groundwater depth 0.91,1.83 and 2.74 m , the crops were utilized its total groundwater 54% of water consumption , 26% and 17% . Thus, agricultural production and groundwater is an integral part of the crop . In this paper, shallow groundwater basin measuring eight Chaihe ion content of the rainy season in the dry season to observe differences in their effects on agricultural production. Experimental study found that : ( 1 ) different locations in shallow groundwater hardness is different, so the area of agricultural production and crop any great impact, experimental results show that the hardness of the water is the best followed by Chuk Yuen Finally, section Guanyin Mountain is seven ; ( 2 ) the dry season and the rainy season after the discovery relevance, conducting statistical analysis of experimental data for each ion and T test some correlation between dry and wet seasons and between each ion is significant but not significant ; ( 3 ) through a comparative analysis between the various ions found in shallow groundwater between sodium and chloride ions which have a significantly ; ( 4 ) experimental results show that the groundwater in the shallow water of the river ion ion there is a great influence , and three different sampling sites in the river water ions for ion- impact situation is different , that is, different locations in different areas of water to the agricultural production also have different effects.
