摘要: 为明确河南省主推小麦品种的适宜播量,以‘周麦22’、‘西农979’、‘郑麦7698’、‘矮抗58’和‘百农207’等五大主导小麦品种为材料,进行多点试验,研究了不同播量对产量及产量构成因素的影响。结果表明:随着播量的增加产量呈上升的趋势,当播量增加到187.50kg/hm2时,产量达到高峰,而继续增加播量则产量呈下降的趋势。产量构成因素方面,单位面积穗数随着播量的逐渐增加而呈现上升的趋势,穗粒数和千粒重则呈现下降的趋势。在适宜播量范围内,5个品种的产量排名从大到小为‘百农207’、‘周麦22’、‘郑麦7698’、‘矮抗58’、‘西农979’。综上所述,当前河南省主推小麦品种适宜播量为150.00~225.00kg/hm2,187.50kg/hm2播量产量最高,为最佳播量。

Abstract: To clarify suitable sowing rate of wheat cultivars in Henan Province, five main wheat cultivars including ‘Zhoumai22’, ‘Xinong979’, ‘Zhengmai7698’, ‘Aikang58’ and ‘Bainong207’ were used as the materials, and the experiments were conduced at different areas. The effects of different sowing rates on the yield and yield components were studied. The results showed that the yield increased gradually with the increase of sowing rate, and reached the maximum when the sowing rate was 187.50 kg/hm2, while the yield showed a declining trend with the continuously increasing sowing rate. In the respect of yield components, the spike number per area showed an upward trend with the increase of sowing rate, but the kernel number per spike and 1000-grain weight showed a downward trend. In the suitable sowing rate, the yield order of five cultivars was:‘Bainong207’>‘Zhoumai22’>‘Zhengmai7698’>‘Aikang58’>‘Xinong979’. Taken together, the suitable sowing rate of wheat cultivars is from 150.00 kg/hm2 to 225.00 kg/hm2, and 187.50 kg/hm2 is the optimum sowing rate which can obtain the maximum yield.
