摘要
针对徐淮地区栽培的夏大豆出现缺铁症造成减产的情况，通过1996－1998三年的田间试验，表明降低土壤的pH值,在夏大豆初花期喷施铁肥，能较好地防治夏大豆缺铁症，达到明显的增产效果。
In recent years, the yield of summer soybeam in Xu - Huai area has been reducing because of Fe- deficency symptom. This article analyzes the main causes of this symptom, and points out that many field experiments from 1996 to 1998 prove that when summer soybeam is added Fe fertilizer during initial flower period and meantime, the number of ph in the soil is decreased, the Fe - deficency symtom of summer soybeam can be prevented and cured so that the yield of summer soybeam can increase obviously.
