摘　　要：为探求冀南地区中低肥力下冬小麦节水稳产的适宜灌溉方式,以该区大面积推广的冬小麦品种邯6172为试验材料,在足墒播种条件下,灌溉方式设未灌越冬水+灌起身水(T1)、灌越冬水+灌起身水(T2处理)、未灌越冬水+灌拔节水(T3处理)和灌越冬水+灌拔节水(T4)4个处理,研究了不同灌溉方式对冬小麦农艺性状及产量的影响。结果表明:越冬水和春一水灌溉时间均对冬小麦生长发育以及产量有显著影响,其中T2处理效果最好,冬小麦株高、旗叶面积、旗叶干重、冠层截获有效辐射(PAR)和子粒产量均最高。在冀南地区中低肥力条件下,T2处理对促进冬小麦生长发育、提高产量效果显著,可以作为该区冬小麦节水稳产的栽培方式。In order to explore the suitable irrigation method for water conservation and stable yield of winter wheat under middle and low fertility in southern Hebei,the winter wheat cultivar Han 6172 popularized in a large scale in this area,was used as test material,four different irrigation methods were set including nonirrigation at overwintering stage+irrigation at standing stage(T1),irrigation at overwintering stage+irrigation at standing stage(T2),non-irrigation at overwintering stage+irrigation at jointing stage(T3),and irrigation at overwintering stage+irrigation at jointing stage(T4),to study the effects of different irrigation methods on the agronomic traits and yield of winter wheat.The results showed that irrigation at overwintering stage and the time of single water in spring had significant effects on the growth and yield of winter wheat.T2 treatment significantly increased the plant height,flag leaf area and dry weight,PAR and yield of winter wheat.T2 treatment was more beneficial to the growth and yield of winter wheat under medium-low fertility in Southern Hebei,which can be used as water conservation and stable yield cultivation of winter wheat in this area.
