摘要: 倒伏是制约小麦生产的重要因素之一。2017年襄阳市襄州区小麦收获面积10.1万hm2,受连续降雨和大风影响,小麦倒伏面积达0.67万hm2。调查结果表明,倒伏小麦平均穗粒数减少3.82粒,减幅为12.75%;千粒重减少3.78 g,减幅为8.78%。倒伏致小麦减产860.62 kg/hm2,减产幅度为12.83%。分析了引起小麦大面积倒伏的原因,并提出防止小麦倒伏的技术措施。

Abstract: Lodging is one of the restriction factors of wheat production. In 2017,the planting area of wheat in Xiangzhou was 1.01×105 hm2. However,caused by lasting rainfall and heavy wind,6.7×103 hm2 of them got flattened. Investigation results showed that,lodging reduced 3.82 grains per spike,a decrease of 12.75%;and 3.78 g of thousand kernel weight(TKW),a decrease of 8.78%. It further reduced the production by 860.62 kg/hm2(12.83%). The reasons of this event were analyzed and the technical measures to prevent lodging were discussed in this survey.
