摘要
为探究年份、地点、品种及其互作效应对大豆产量的影响,文章以河南省审定通过的11个大豆品种为研究对象,对2022—2023年在河南省7个地点的大豆产量进行多因素方差分析和多重比较。结果表明,驻马店试验准确度最高,漯河对参试品种的鉴别能力最强。年份、地点、品种及其互作效应对大豆产量影响均达极显著水平(P<0.01),地点对大豆产量贡献率最大,为62.91%。7个地点中,除洛阳和漯河平均产量差异不显著外,其他地点差异均显著。原阳平均产量最高,为3776.43 kg/hm^(2),较平均产量最低的南阳高105.15%。11个参试品种平均产量均显著高于豫豆22号(CK),郑1311平均产量最高,达3049.7 kg/hm^(2),增产幅度为14.35%;明豆1号增产幅度最低,为4.24%。在实际生产中,根据不同环境条件选择高产、优质、适应性强品种更有利于发挥品种高产潜力。
In order to explore the influence of year,place,variety and their interaction effect on soybean yield,11 soybean varieties approved by Henan Province were took as research objects,and the soybean yield of seven experimental sites in Henan Province from 2022 to 2023 was compared by multivariate variance and multivariate comparison.The results showed that the test accuracy of Zhumadian and Luohe had the strongest identification ability for the tested varieties.The effects of year,location,variety and their interaction on soybean yield reached a very significant level(P<0.01).The contribution rate of location to soybean yield was 62.91%.Among the seven experimental sites,except Luoyang and Luohe,the average yield difference was significant among other experimental sites.The average yield of original sun was 3776.43 kg/ha,which was 105.15%higher than that of Nanyang,which had the lowest average yield.The average yield of 11 tested varieties was significantly higher than that of Yudou 22(CK),and the average yield of Zheng 1311 was 3049.7 kg/ha,with an increase of 14.35%;Mingdou 1 has the lowest yield increase of 4.24%.In actual production,selecting varieties with high yield,good quality and strong adaptability according to different conditions was more conducive to exerting the high yield potential of varieties.
