采用裂区设计，对6个冬小麦品种在3种灌溉模式条件下的籽粒产量和主茎的穗部性状进行研究，以探索灌溉模式对冬小麦穗部性状的影响以及不同性状与籽粒产量之间的关系。结果表明，不同灌溉模式下，冬小麦主茎的穗长、穗颈节长、穗颈节直径、穗粒数、产量的差异均不显著；不同品种间，冬小麦穗长、穗颈节长、穗颈节直径差异极显著，穗粒数、产量差异显著。说明灌水模式对冬小麦穗部性状的影响小于遗传因素的影响，遗传因素对穗部性状起决定作用。小麦产量与穗粒数呈正相关（ y＝4.87393＋0.00139 x ），穗长与穗粒数呈负相关（ y＝86.1849-4.29284 x ），穗颈节直径与穗粒数呈正相关（ y＝2.56715＋0.01455 x ），穗颈节长与穗粒数呈正相关（ y＝32.73105＋0.61915 x ）。在所有组合中，以采用底墒水模式、选用陕538小麦品种产量最高，为8175 kg/hm2。
採用裂區設計，對6箇鼕小麥品種在3種灌溉模式條件下的籽粒產量和主莖的穗部性狀進行研究，以探索灌溉模式對鼕小麥穗部性狀的影響以及不同性狀與籽粒產量之間的關繫。結果錶明，不同灌溉模式下，鼕小麥主莖的穗長、穗頸節長、穗頸節直徑、穗粒數、產量的差異均不顯著；不同品種間，鼕小麥穗長、穗頸節長、穗頸節直徑差異極顯著，穗粒數、產量差異顯著。說明灌水模式對鼕小麥穗部性狀的影響小于遺傳因素的影響，遺傳因素對穗部性狀起決定作用。小麥產量與穗粒數呈正相關（ y＝4.87393＋0.00139 x ），穗長與穗粒數呈負相關（ y＝86.1849-4.29284 x ），穗頸節直徑與穗粒數呈正相關（ y＝2.56715＋0.01455 x ），穗頸節長與穗粒數呈正相關（ y＝32.73105＋0.61915 x ）。在所有組閤中，以採用底墑水模式、選用陝538小麥品種產量最高，為8175 kg/hm2。

With the split plot design ,the grain yield and main stem panicle traits of six winter wheat varieties were studied under three irrigation modes ,to explore the effect of irrigation modes on the panicle traits of winter wheat and the relationships between different traits and grain yield .The re-sults showed that the spike length of main stem ,length of spike neck ,diameter of spike neck ,grain num-ber per spike and grain yield of winter wheat were not significantly different among different irrigation modes ,indicating that the influence of irrigation modes on spike characters of winter wheat was less than that of genetic factors ,and the genetic factors had the decisive role to ear characters .The grain yield of wheat had positive correlation with grain number per spike (y=4.873 93+0.001 39 x) .The grain num-ber per spike had negative relation with the spike length (y=86.184 9-4.292 84 x) ,but was positively related to the diameter of spike neck (y=2 .567 15+0 .014 55 x) and the length of spike neck (y=32.731 05+0.619 15 x) .In all the combinations ,the highest yield (8 175 kg/ha) came from the wheat variety Shaan 538 with the bottom irrigation mode .
