摘要:

【目的】 研究新疆北疆包蛋麦冬性小麦、春性小麦品种间干物质积累、灌浆特性及产量的差异。【方法】 田间采用包蛋种植方式比较冬、春性小麦品种的干物质积累、灌浆特性及产量的差异。【结果】 冬性品种包蛋以新冬41号产量较高,为7 812.3 kg/hm2,春性品种包蛋以新春6号产量较高,为7 935.6 kg/hm2。冬性品种总干物质积累量在14 727.8~16 983.26 kg/hm2,春性品种总干物质积累量在13 588.6~17 634.7 kg/hm2,冬性品种成熟期干物质积累量平均值(16 140.9 kg/hm2)比春性品种(15 804.1 kg/hm2)高2.09%,但冬、春性品种间差异不明显。冬性小麦品种花后同化物向籽粒分配量平均值、分配率平均值、对粒重贡献率平均值依次为4 508.46 kg/hm2、57.13%、78.78%,与春性小麦品种(依次为4 324.77 kg/hm2、56.36%、77.71%)均差异不明显。春性小麦品种包蛋快速增长持续时间的平均值(16.25 d)、最大灌浆速率的平均值(2.23 g/d)、平均灌浆速率的平均值(1.12 g/d),冬性小麦品种包蛋依次为15.70 d、2.22 g/d、1.09 g/d,冬、春性小麦品种之间的差异未达显著水平。【结论】 新春6号、新冬41号是适合新疆北疆小麦包蛋种植方式的品种。

Abstract:

【Objective】 To explore the differences in dry matter accumulation, grain filling characteristics and yield among varieties of winter and spring wheat in Northern Xinjiang. 【Methods】 The difference of dry matter accumulation, grain filling characteristics and yield between winter and spring wheat varieties was compared by using for overwinter seeds planting method. 【Results】 The results showed that Xindong 41was 7,812.3 kg/hm2, relatively higher than other winter wheat varieties, and that of spring wheat varieties Xinchun6 was 7,935.6 kg/hm2 that was higher than other spring wheat varieties. The total dry matter accumulation of winter varieties was between 14,727.8-16,983.26 kg/hm2, the total dry matter accumulation of spring varieties was between 13,588.6-17,634.7 kg/hm2, and the average dry matter accumulation of winter varieties at maturity (16,140.9 kg/hm2) was 2.09% higher than that of spring varieties (15,804.1 kg/hm2), but the difference between winter and spring varieties was not obvious. The average assimilation to grain distribution, the average distribution rate, and the average granular weight contribution rate of winter wheat varieties were 4,508.46 kg/hm2, 57.13%, 78.78% in turn, which was not significantly different from those of spring wheat varieties (4,324.77 kg/hm2, 56.36%, 77.71% in order). The average value of the rapid growth duration of winter wheat varieties (16.25 d), the average value of the maximum grouting rate (2.23 g/d), the average grouting rate (1.12 g/d), the winter wheat varieties were 15.70 d, 2.22 g/d, 1.09 g/d in turn, and the difference between winter and spring wheat varieties has not reached a significant level. 【Conclusion】 Combining the above research results, it is believed that Xinchun 6 and Xindong 41 are suitable for the cultivation of wheat varieties for overwinter seeds cultivation in northern Xinjiang.
