【目的】以先进灌区的灌溉水平来衡量,挖掘新疆农业节水的潜力。【方法】设不同灌水处理其对冬小麦群体变化、单株生物重、株高、穗部性状、叶面积、产量等指标进行研究。【结果】水分胁迫会影响小麦的生物量、叶面积和分蘖等群体发育指标,并通过光合营养等作物生理过程的影响而限制小麦高产。【结论】对试验区冬小麦春后灌水时期而言,拔节期和孕穗期是个重要时期,孕穗期前灌水与孕穗期和孕穗期后灌水有一定的差异,春后前期灌水对产量的贡献明显高于后期灌水。
[Objective] To measure the irrigation level of advanced irrigation areas and tap the potential of water saving in agriculture in Xinjiang. 【Method】 Different irrigation treatments were used to study the population changes, biomass per plant, plant height, ear traits, leaf area and yield of winter wheat. 【Result】 The results showed that water stress would affect the population development index of wheat such as biomass, leaf area and tiller, and restrict the high yield of wheat through the influence of photosynthesis and other crop physiological processes. 【Conclusion】 The results showed that the jointing stage and booting stage were important periods for winter wheat irrigation in the experimental area. There was a certain difference in irrigation between booting stage and booting stage and booting stage, and the contribution of irrigation in early spring to the yield was obviously higher Irrigation in the late.
