摘 要:[目的]探讨不同栽培技术体系对济麦20产量及水分利用效率的影响,以筛选与气候、生产条件相适应的高产优质高效栽培技术。[方法]在大田条件下,以济麦20(JM20)为供试材料,设置低密度适期早播精播栽培技术(T1)、稳妥型改良精播栽培技术(T2)、中密度适期晚播限量灌溉栽培技术(T3)和高密度晚播限量灌溉栽培技术(T4)4种栽培技术体系。分析4种不同技术体系对JM20产量及水分利用效率等指标的影响。[结果]JM20子粒产量以采用稳妥型改良精播栽培技术最高,显著高于采用其他3种栽培体系的子粒产量;水分利用效率以采用中密度适期晚播限量灌溉栽培技术最高,显著高于低密度适期早播精播栽培技术,但与稳妥型改良精播栽培技术和高密度晚播限量灌溉栽培技术差异不显著。[结论]稳妥型改良精播栽培技术更能实现JM20的高产高效,适宜于节水并兼顾全年产量为主地区应用。[ Objective ] To discuss the cultivation technology system on water use efficiency of Jimai 20 yield, and to screen the high-yield, high-quality and high-efficiency cultivation technology of wheat. [ Method ] Under field conditions, Jimai 20(JM20) was used as the materi- als. Four cultivation systems were designed, which were low density and suitable early sowing precision sowing technology (T~), steady im- provement of precision sowing technology ( T2 ), medium density and suitable late sowing technology ( T3 ) and high density late sowing tech- nology ( T4 ). Effects of these four systems on the yield and water use efficiency of JM20 were researched. [ Result] The yield of JM20 was the highest in T2 , which was significantly higher than other three technology systems. Compared with T1, the water use efficiency of winter wheat was significantly increased in T3, but there was no significant difference among T3, T2 and T4. [ Conclusion] T2 achieves the highest yield and water use efficiency in JM20, which is suitable for the areas where need both water saving and annual equilibrating yield.
