To investigate the yield characteristics and temperature and light use efficiency of early-maturing wheat varieties under late sowing after rice stubble and early harvest in the southwestern, a two-factor split-plot experiment was designed, with sowing date as the main plot namely, early sowing (S1, 23 October), regular sowing (S2, 30 October), late sowing for 7 d (S3, 6 November), late sowing for 14 d (S4, 13 November), and late sowing for 21 d (S5, 20 November), and planting density as the split-plot (2.50×106, 3.25×106, 4.00×106 plants·hm-2), to study the effects of sowing date and planting density on yield and its components, dry matter accumulation and translocation, filling characteristics and temperature, light use efficiency of winter wheat. The results showed that there was no significant difference in wheat yield among S2, S3 and S4, while S1 and S5 reduced yields by 7.6% and 32.2%, respectively, compared to S2. There is no significant difference in yield between different planting densities. Late sowing can shorten the entire growth period of winter wheat, and reduce the effective accumulated temperature and daily average temperature before jointing. Compared with S2, S3, S4 and S5 reduced the accumulated temperature during wheat growth by 65.4, 84.1 and 93.8 ℃, and the daily average temperature by 1.3, 2.4 and 3.7 ℃, respectively. Late sowing increased the daily average temperature during jointing to booting and booting to flowering stages, reduced the effective number of spikes, and increased the number of grains per spike. Late sowing wheat has abundant temperature and light resources after flowering, manifested by an increase in daily average temperature and radiation after flowering, an increase in dry matter accumulation after flowering, an acceleration in grain filling rate, a shortened duration of grain filling, and stable grain weight. Increasing planting density increased the contribution rate of pre-flowering dry matter, reduced the duration and activity time of grain filling, and had a relatively small impact on the grain filling rate. Moderate late sowing can improve temperature use efficiency, with an increase rate of 2.24% and 8.02% for S3 and S4, respectively, compared to S2. In summary, late sowing winter wheat can achieve stable yield by increasing the number of grains per ear, and the accumulation amount and transport efficiency of dry matter after flowering can be improved.

为探究西南麦区稻麦周年丰产下早熟小麦品种晚播早收的丰产特性及温光利用效率,2022—2023年以早熟小麦品种蜀麦1963为材料,采用二因素裂区试验,主区设置早播(S1,10月23日)、常规播期(S2,10月30日)、晚播7 d(S3,11月6日)、晚播14 d(S4,11月13日)和晚播21 d(S5,11月20日)5个播期,裂区设2.50×106、3.25×106、4.00×106株·hm-2共3个种植密度,研究了播期和种植密度对冬小麦产量及构成因素、干物质积累与转运、灌浆特性及温光利用效率的影响。结果表明,S2、S3和S4间小麦产量无显著差异,S1和S5较S2分别减产7.6%和32.2%;不同种植密度间产量无显著差异。晚播可缩短冬小麦全生育期天数,降低拔节前有效积温和日均温,与S2相比,S3、S4和S5的小麦生育期积温分别减少了65.4、84.1和93.8 ℃,日均温分别降低了1.3、2.4 和3.7 ℃,拔节期—孕穗期和孕穗期—开花期日均温均增加。晚播也减少了有效穗数,提高了穗粒数。晚播小麦花后温光资源充足,表现为花后日均温、日均辐射量增加,花后干物质积累量增加,灌浆速率加快,灌浆持续时间缩短,粒重稳定。增加密度提高了花前干物质对籽粒产量的贡献率,减少了灌浆持续时间和灌浆活跃时间,对灌浆速率影响较小。适时晚播可提高温度利用效率,S3和S4的温度利用效率较S2分别提高了2.24%和8.02%。综上所述,晚播冬小麦可通过提高穗粒数获得稳产,且花后干物质积累量及转运速度提高。

为探究西南麦区稻麦周年丰产下早熟小麦品种晚播早收的丰产特性及温光利用效率,2022—2023年以早熟小麦品种蜀麦1963为材料,采用二因素裂区试验,主区设置早播(S1,10月23日)、常规播期(S2,10月30日)、晚播7 d(S3,11月6日)、晚播14 d(S4,11月13日)和晚播21 d(S5,11月20日)5个播期,裂区设2.50×106、3.25×106、4.00×106株·hm-2共3个种植密度,研究了播期和种植密度对冬小麦产量及构成因素、干物质积累与转运、灌浆特性及温光利用效率的影响。结果表明,S2、S3和S4间小麦产量无显著差异,S1和S5较S2分别减产7.6%和32.2%;不同种植密度间产量无显著差异。晚播可缩短冬小麦全生育期天数,降低拔节前有效积温和日均温,与S2相比,S3、S4和S5的小麦生育期积温分别减少了65.4、84.1和93.8 ℃,日均温分别降低了1.3、2.4 和3.7 ℃,拔节期—孕穗期和孕穗期—开花期日均温均增加。晚播也减少了有效穗数,提高了穗粒数。晚播小麦花后温光资源充足,表现为花后日均温、日均辐射量增加,花后干物质积累量增加,灌浆速率加快,灌浆持续时间缩短,粒重稳定。增加密度提高了花前干物质对籽粒产量的贡献率,减少了灌浆持续时间和灌浆活跃时间,对灌浆速率影响较小。适时晚播可提高温度利用效率,S3和S4的温度利用效率较S2分别提高了2.24%和8.02%。综上所述,晚播冬小麦可通过提高穗粒数获得稳产,且花后干物质积累量及转运速度提高。

To investigate the yield characteristics and temperature and light use efficiency of early-maturing wheat varieties under late sowing after rice stubble and early harvest in the southwestern, a two-factor split-plot experiment was designed, with sowing date as the main plot namely, early sowing (S1, 23 October), regular sowing (S2, 30 October), late sowing for 7 d (S3, 6 November), late sowing for 14 d (S4, 13 November), and late sowing for 21 d (S5, 20 November), and planting density as the split-plot (2.50×106, 3.25×106, 4.00×106 plants·hm-2), to study the effects of sowing date and planting density on yield and its components, dry matter accumulation and translocation, filling characteristics and temperature, light use efficiency of winter wheat. The results showed that there was no significant difference in wheat yield among S2, S3 and S4, while S1 and S5 reduced yields by 7.6% and 32.2%, respectively, compared to S2. There is no significant difference in yield between different planting densities. Late sowing can shorten the entire growth period of winter wheat, and reduce the effective accumulated temperature and daily average temperature before jointing. Compared with S2, S3, S4 and S5 reduced the accumulated temperature during wheat growth by 65.4, 84.1 and 93.8 ℃, and the daily average temperature by 1.3, 2.4 and 3.7 ℃, respectively. Late sowing increased the daily average temperature during jointing to booting and booting to flowering stages, reduced the effective number of spikes, and increased the number of grains per spike. Late sowing wheat has abundant temperature and light resources after flowering, manifested by an increase in daily average temperature and radiation after flowering, an increase in dry matter accumulation after flowering, an acceleration in grain filling rate, a shortened duration of grain filling, and stable grain weight. Increasing planting density increased the contribution rate of pre-flowering dry matter, reduced the duration and activity time of grain filling, and had a relatively small impact on the grain filling rate. Moderate late sowing can improve temperature use efficiency, with an increase rate of 2.24% and 8.02% for S3 and S4, respectively, compared to S2. In summary, late sowing winter wheat can achieve stable yield by increasing the number of grains per ear, and the accumulation amount and transport efficiency of dry matter after flowering can be improved.
