小麦湿(渍)害,是指土壤水分达到饱和时,造成空气不足,而对小麦正常生长发育所产生的危害。主要发生在长江中下游平原的稻茬麦田,每年均有不同程度的发生。一、小麦湿(渍)害的危害小麦湿(渍)害的危害主要表现为:受湿害的小麦根系长期处在土壤水分饱和的缺氧环境,根系吸收功能减弱,造成植株体内水分亏缺,严重时造成脱水凋萎或死亡,因此湿害又常表现为生理性干旱。小麦从苗期至扬花灌浆期都 Wheat wet (stain) damage, refers to the soil moisture reaches saturation, resulting in lack of air, but the normal growth and development of wheat caused harm. Mainly occurred in the middle and lower reaches of the Yangtze River rice fields in wheat fields, each year to varying degrees of occurrence. First, the harm of wheat wet (stain) harm The main damage caused by wet (stain) wheat: the wet wheat roots in the long-term soil moisture saturated hypoxia, weakening of the root absorption, resulting in plant water deficit , Severe dehydration caused wilting or death, so wet damage is often manifested as physiological drought. Wheat from seedling to flowering stage are
