| Abstract: | The main reasons for cultivation soil salted in farming irrigating regions of Hexi corridor are overflowing irrigation,string irrigation,non-leveling farmland,non-distributed irrigation,high volume of chemical fertilizer,unreasonable cultivation system,farming abandon and trench leakage. The countermeasures of prevention and cure are to level off farming land,to plant densely with reason,to increase the volume of organic fertilizer,to save water and prevent farming abandon. |
