调查发现关中猕猴桃产区渭河两岸的河滩地及低洼地果园缺铁性黄化病发生普遍 ,程度严重 ;距离渭河滩较远的二级阶地及台塬地上的果园发病较轻 ;位于秦岭山脚的山前洪积扇地区果园基本上无黄化病发生。导致猕猴桃缺铁性黄化病发生的因素主要有土壤 p H偏高 ,树体严重超载 ,灌水过多及其他栽培因素 ;美味猕猴桃对黄化病的抵抗力较中华猕猴桃强 ,海瓦德品种及陕猕 1号的抗性优于秦美品种 ;对黄化病防治提出了综合防治建议

摘  要:
In the center area of Shaanxi,the occurrence of iron deficiency chlorosis of kiwis was widespread and serious on flood land along banks of Wei River and in low lying land, it was less on the second terrace land and table land, and was seldom on the alluvial fan area along the foot of Qinling Mountains. Main inducing factors of iron deficiency chlorosis are higher soil pH, over loading,over irrigating and other cultural practice. Actinidia deliciosa has higher resistant ability to iron deficiency chlorosis than A.chinesis. Cultivars Hayward and Shaanmi 1 are harder than Qinmei to iron deficiency chlorosis.Suggestions on comprehensive control of iron deficiency chlorosis are delivered.
