| 摘 要： | 为研究行距对晚播冬小麦群体物质积累、水分利用的影响,设置行距为12、20、30cm 3个处理,分析不同行距处理的群体物质积累、叶面积指数、水分消耗参数、产量和水分利用效率。结果表明,在晚播限水灌溉条件下,适当缩小行距(12cm)可以增加冬小麦群体叶面积指数,提高群体物质积累和花后物质积累比例;与30cm行距相比,12cm行距能充分利用40~120cm土体内的土壤水分,显著提高产量和水分利用效率(19.8~20.4kg/(hm2·mm))。适当缩小行距至12cm可能是提高晚播冬小麦产量和水分利用效率的有效措施。

| Abstract: | To investigate the effects of rowing space on the population dry matter accumulation and water utilization of late-sowing winter wheat, three rowing spaces (12 cm (R12), 20 cm (R20), 30 cm (R30)) were designed, and the population dry matter, leaf area index, the water consumption parameter, yield and water use efficiency were analyzed.The results indicated that reducing aptly rowing space to 12 cm under the late-sowing and limited water condition could increase the leaf area index, enhance the population dry matter and the ratio of dry matter post-anthesis.Compared to the R30, the more water of 40-120 cm soil layer under R12 was used, the yield and the water utilization efficiency (19.8-20.4 kg/(hm2·mm)) of R12 population were significantly higher.Reducing aptly rowing space to 12 cm might be an effective measure to increase population yield and water use efficiency in late-sowing winter wheat. |
