喷灌水分处理对冬小麦产量及籽粒品质的影响.

In order to explore the irrigation index of winter wheat with sprinkling irrigation in North China, a 2-yeargrowing season(2010-2012) field experiment was carried out to investigate the effects of economic yield, grain quality and water use efficiency of winter wheat with different sprinkling irrigation. The results show that the different effects of water-deficits on biomass, economic yield, grain quality and water use efficiency based on the growing stages in which the water deficits are applied. There is no significantly decreased grain yield, but the grain quality water use efficiency and irrigation water use efficiency are significantly increased and the protein ratio and gluten ratio have been improved when water deficits applied during from turning green to elongation stage and grain filling of winter wheat. Comprehensive consideration economic yield, grain quality, water use efficiency especially irrigation water use efficiency, irrigation strategy of T2, T3 and T6 can be used as appropriate sprinkling irrigation mode for the local winter wheat.
