摘要
为明确小麦品种衡H1401的抗旱节水特性,以抗旱节水冬小麦品种衡H1401和河北省小麦区域试验水地组对照品种衡4399(CK)为试验材料,在水、节水、旱3种水分条件下对小麦主要性状进行了测定,并对衡H1401的抗旱节水性进行了评价。结果表明:旱处理下,衡H1401维持了较高的单位面积穗数和千粒重,抗旱指数达到1.265;灌浆期叶片SPAD值和单株生物量始终高于衡4399,灌浆中后期旗叶失水速率低于衡4399。衡H1401具有突出的抗旱节水性,适宜在地下水压采区进行抗旱节水种植。
In order to clarify the drought resistance and water-saving characteristics of wheat variety Heng H1401,the main characters were determined under three water conditions of water,water saving and drought,and the drought resistance and water-saving ability of Heng H1401 were evaluated.The results showed that under the drought treatment,Heng H1401 maintained higher panicles per unit area and 1000 grain weight,and the drought resistance index reached 1.265.SPAD value and biomass of leaves at grain filling stage were always higher than Heng 4399,and the water loss rate of flag leaves at middle and late grain filling stage was lower than Heng 4399.Heng H1401 has outstanding drought resistance and water saving ability,which is suitable for drought resistance and water saving planting in underground water pressure mining area.
