摘要: 为了建立冬小麦干旱灾害监测与评估的形态特征指标,利用1980—2013年冬小麦生育期间的干旱灾害观测资料和典型干旱年份的调查数据,结合干旱胁迫试验,通过采用定性与定量统计分析方法,分析研究了干旱发生期间冬小麦茎、叶、穗、粒、株高、叶面积等主要形态特征参量的变化。从而得到了安徽省淮北平原冬小麦播种—三叶期、苗期(三叶—分蘖期—越冬前)、越冬期、返青—拔节期、拔节—抽穗(开花)期、抽穗(开花)—乳熟期6个生育时段,发生轻度、中度、重度和特重类型干旱时的主要形态特征及其分级标准。可作为冬小麦干旱灾害田间调查分级的参考依据。

Abstract: To established the mainly morphological characteristics for monitoring and evaluation of drought for winter wheat, this paper studied the main morphological traits of stem, leaf, ear, particle, plant height, leaf area during drought period in Huaibei plain by the qualitatively and quantitatively statistical analysis, based on the observation data of drought disaster during winter wheat growth period from 1980 to 2013 and drought stress experiment. In addition, this paper divided the winter wheat growth period into six growth stages, respectively sowing-trileaf stage, seeding stage, wintering stage, greenup-jointing stage, jointing-heading stage, heading to milking maturity stage and established the mainly morphology characteristics and grade standard of winter wheat corresponding to different growth stages and different disaster grade (mild, moderate, severe, special, severe). The grade standard can be used to be reference for defining the drought disaster grade in field investigation.
