小麦后期倒伏是影响小麦产量的重要因素。倒伏分根倒和茎倒,根倒是由于耕作层浅根系下扎浅,造成灌浆后期倒伏。茎倒是由于栽培管理措施不当,基部节间长,植株过高或病虫危害茎秆,造成茎秆强度差、韧性差,遇到大风大雨造成茎秆倒伏。加强栽培管理措施可以增强小麦抗倒性,降低倒伏机率。今年5月31日-6月5日笔者对农户的整地、播量、播期、施肥、浇水等栽培措施进行了调查(5月23日的大风大雨造成我县小麦大面积倒伏)。通 Post-wheat lodging is an important factor affecting wheat yield. Lost root down and down the stem, the root is due to tillage shallow roots shallow system, resulting in the late grouting lodging. Stems due to improper cultivation and management practices, the base of the internode, plant over or pest damage to stems, resulting in poor stem strength, poor toughness, stems caused by winds and heavy stalk lodging. Strengthening cultivation management measures can enhance wheat lodging resistance and reduce the chances of lodging. From May 31 to June 5 this year, the author conducted an investigation on the cultivation measures such as land preparation, sowing date, sowing date, fertilization and watering of the farmer (heavy winds and heavy rain caused heavy dumping of wheat in our county on May 23). through
