【摘要】 为了探讨大田生产条件下提高小麦水分生产效率的技术措施,在垄作和传统平作两种栽培模式下,比较研究了株型扩张型(spread)品种烟农19、株型紧凑型(crect)品种泰山23和株型半扩张型(semi-erect)品种济麦20的水分生产效率及不同株型小麦品种与栽培模式对水分生产效率的互作效应。结果表明,烟农19旗叶光合速率高于济麦20和泰山23,并且蒸腾系数较低,属水分高效型品种;垄作栽培与平作相比能够取得较高的光合速牢和较低的蒸腾系数,属水分高效型栽培技术;水分高效型品种与水分高效型栽培技术结合能够取得较高的水分生产效率。更多还原

【Abstract】 Three cultivars of wheat,Yannong 19(with spread plant type),Jimai 20(with semi-spread plant type)and Taishan 23(with erect plant type),were used to investigate the WUE(water use efficiency)under raised bod planting with furrow irrigation and conventional flat planting with flood irrigation.The results showed that Yannong 19 with spread plant type had the highest photosynthetic rate and the lowest transpiration coefficient among the three cultivars either in raised bed planting with furrow irrigation or conventional flat planting with flood irrigation.Yannong19 is the variety with highest water use efficiency.The results also showed that the wheat population under raised bed planting with furrow irrigation had higher water use efficiency(WUE)than that of conventional flat planting with flood irrigation,varieties with higher water use efficiency integrating with raised bed planting with furrow irrigation could acquire ideal WUE.更多还原
