摘要
为构建适合河南小麦成熟期连阴雨灾害强度指数,并明确河南小麦受连阴雨影响的敏感时段,利用河南省111个测站1961—2023年气象资料及有关农业气象观测站数据,分析了2023年河南小麦连阴雨受灾及相关发育期情况,以及主要气象因子和连阴雨灾害调查数据的相关性,并根据前人研究成果,结合河南实际,构建了3种小麦成熟期连阴雨灾害强度指数。结果表明:(1)小麦开花后35天以上,是小麦籽粒品质受连阴雨天气影响最敏感的时段。(2)成熟期连阴雨灾害强度指数L2和L3均能够很好地吻合2023年河南小麦因连阴雨灾害的受灾情况,特别是L3兼具实用性和准确性,能够满足业务服务需要。(3)2023年河南省小麦成熟期连阴雨灾害强度指数L2、L3空间分布都表现为南高北低,全省平均L2为0.81,L3为0.32,均为1961年以来的最高值。
To construct the continuous rain disaster intensity index suitable for winter wheat maturity in Henan Province and to clarify the sensitive time of wheat affected by continuous rain there,this article analyzes the continuous rain disaster and the related development of stages of wheat in Henan in 2023 and studies the correlation between major meteorological factors and the disaster intensity index of continuous rain by using meteorological and agrometeorological observations of 111 stations in Henan from 1961 to 2023.Three kinds of disaster intensity indexes of continuous rain during winter wheat maturity are constructed based on the results of previous research combined with the actual situation in Henan.The results show that:(1)More than 35 days after winter wheat flowering is the most sensitive time for wheat grain quality to be affected by continuous rain.(2)The continuous rain disaster intensity index L 2 and L 3 at the maturity stage of winter wheat can be in good agreement with the Henan winter wheat disaster condition in 2023 due to the continuous rain event.Especially,the index L 3 is practical and accurate,able to meet the needs of operational service requirements.(3)In 2023,the spatial distributions of the intensity indexes L 2 and L 3 of continuous rain disaster during wheat ripening in Henan both are high in the south and low in the north,with L 2 being 0.81 and L 3 being 0.32 on average in the whole province,and both are the highest values since 1961.
