渍害是湖北省小麦生产上最常见的自然灾害,是全省小麦高产、稳产的主要限制因素之一。它不仅在降雨量大、地势低洼、地下水位高的江汉平原及沿江滨湖麦区发生频率高,为害损失重,而且在鄂北麦一稻两熟地区,也会由于前作水稻使得土壤浸水时间长、土壤粘重、排水困难、透气性差而出现渍害。渍害在小麦生长发育的各个阶段都有发生,尤其以孕穗对水分最为敏感,孕穗期渍害对产量的影响最大。为了了解渍害对小 Waterlogging is the most common natural disasters in wheat production in Hubei Province, is one of the main limiting factors of high yield and stable yield of wheat in the province. It is not only heavy rainfall, low lying, high groundwater levels of the Jianghan Plain and the Lakeside Lakes high frequency of occurrence, loss of weight damage, but also in northern Hubei and northern regions of wheat and rice will also make the former as paddy soil soaking time Long, sticky soil, drainage difficulties, poor permeability and stains appear. Waterlogging in all stages of wheat growth and development have occurred, in particular, the most sensitive to water booting, booting stains have the greatest impact on the yield. In order to understand the stains on the small
