Abstract:

The main reasons for cultivation soil salted infarming irrigating regions of Hexi corridor are over flowing 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 cureare to level off farming land,to plant densely with reason, to increase the volume of organic fertilizer,to save water and prevent farming abandon.

Key words: Hexi Corridor, soil salted, irrigation, countermeasure

摘要:

产生河西走廊耕作土壤次生盐渍化的主要成因,概括起来为大水漫灌、串灌;大块田土地不平整,灌水不均匀;化肥施用量过高;作物耕作制度不合理;土地弃耕和渠道渗漏等。治对策是平整土地、合理密植、增大有机肥施用量、节水灌溉防止弃耕。
