摘要:

【目的】 研究不同磷肥施用方式对干播湿出小麦光合特性、叶绿素荧光及产量的影响,筛选干播湿出模式下滴灌小麦磷肥施用方式。【方法】 在大田试验条件下,以新冬22号为材料,采用双因素裂区试验设计,主区设置造墒播种(F)和干播湿出(D)2种出苗水方式;副区在总施磷量一致条件下设置3种磷肥施用方式,100%基施(P1)、70%基施+30%滴施(P2)、50%基施+50%滴施(P3),分析不同施磷方式对干播湿出小麦光合特性、叶绿素荧光及产量的影响。【结果】 磷肥后移显著增加了小麦的叶片SPAD值和LAI,分别提高0.88%~7.63%和7.25%~49.38%。在小麦光合特性中,各指标均随生育时期的推进呈下降趋势,其中DP3处理表现最佳,PnTrGs在开花期分别为25.59μmol/(m2·s)、18.21mmol/(m2·s)和0.73mmol/(m2·s),Ci最低为324.88μmol/mol,且处理间差异显著。磷肥后移有效提高了穗数、穗粒数和千粒重,分别较FP1处理提高了1.36%~18.43%、0.59%~4.06%和0.77%~7.21%。籽粒产量表现为DP3>DP2>FP3>FP2>DP1>FP1,与FP1相比,各处理增产幅度均在4.5%以上。【结论】 DP3处理(50%基施+50%追施)冬小麦光合有促进作用,产量及产量构成因素表现最佳,有利于磷肥高效利用。

Abstract:

【Objective】 To study the effects of different phosphorus fertilizer application methods on the photosynthesis characteristics, chlorophyll fluorescence and yield of dry-seeded wet-irrigated winter wheat, and to provide theoretical basis for phosphorus fertilizer application methods in dry-seeded wet-irrigated mode under drip irrigation. 【Methods】 Under field test conditions, Xindong 22 was used as experimental material, and a two-factor split plot experiment design was adopted. Two kinds of seedling emergence water methods were set up in the main plot: sowing (F) and dry sowing (D). Under the condition of the same total phosphorus application amount, three phosphorus application methods were set up in the secondary district, 100% base application (P1), 70% base application +30% drop application (P2), 50% base application +50% drop application (P3), and the effects of different phosphorus application methods on photosynthetic characteristics, chlorophyll fluorescence and yield of wet wheat were analyzed. 【Results】 Phosphorus fertilizer postpone significantly increased leaf SPAD value and LAI of wheat by 0.88%-7.63% and 7.25%-49.38%, respectively. In the photosynthetic characteristics of wheat, all indexes showed a downward trend with the growth period, among which DP3 treatment showed the best performance, Pn, Tr and Gs were 25.59μmol/ (m2·s), 18.21 mmol/ (m2·s) and 0.73 mmol/ (m2·s) at flowering stage, respectively. The lowest Ci was 324.88μmol/mol, and the difference between treatments was significant. The number of panes, grains per spike and 1000-grain weight were increased by 1.36%-18.43%、0.59%-4.06% and 0.77%-7.21%, respectively, compared with FP1 treatment. The grain yield was DP3>DP2>FP3>FP2>DP1>FP1. Compared with FP1, the yield increase of each treatment was more than 4.5%. 【Conclusion】 DP3 treatment (50% base application +50% topdressing) can promote photosynthesis of winter wheat under the experimental conditions, and the yield and yield components have the best performance.
