摘要: 【目的】研究不同滴灌带配置对新疆滴灌春小麦产量的影响。【方法】 在田间试验条件下,以春小麦品种新春44号为材料,设置3种滴灌带配置:1管1行(TR4,对照)、1管6行(TR6)和1管8行(TR8),研究靠近滴灌带的第1(R1)、第2(R2)、第3(R3)和第4行(R4)行间植株产量的差异。【结果】 TR6和TR8植株叶面积比TR4分别减少了5.80%和8.69%,其株高降低了1.03%和2.71%。各行小麦植株干物质积累量和产量均随着滴灌带间距的增长而下降,R1和R2行干物质积累和籽粒产量显著高于R3和R4行,其它各项指标也呈相近的趋势,R3和R4常处于水分亏缺状态。【结论】 水肥条件下滴灌春小麦穗粒数对产量的影响为直接效应,千粒重为间接效应。

Abstract: 【Objective】 To clarify the effect of different drip irrigation belt configurations on spring wheat yield in Xinjiang under drip irrigation.【Methods】 Under field test conditions, using spring wheat variety Xinchun 44 as the material, three drip irrigation band configurations were set up: one tube (1 row (TR4, control)), 6 lines (TR6), and 8 lines (TR8). Differences in plant yield between the first (R1), second (R2), third (R3), and fourth (R4) rows of the belt.【Results】 Compared with TR4, the leaf area of TR6 and TR8 plants decreased by 5.80% and 8.69%, respectively, and their plant height decreased by 1.03% and 2.71%. The dry matter accumulation and yield of wheat plants in each row decreased with the increase of the distance from the drip irrigation zone. The dry matter accumulation and grain yield in rows R1 and R2 were significantly higher than those in rows R3 and R4.【Conclusion】 Other indicators also showed similar trends. Indicating that R3 and R4 are often in a water deficit state. The path analysis results show that the effect of grain number per ear on yield under direct water and fertilizer conditions is a direct effect, and thousand-grain weight is an indirect effect.

Key words: spring wheat; drip irrigation zone configuration; dry matter; filling rate; leaf area; yield
