摘 要:为不同熟期组大豆品种在河北沧州的推广应用提供依据,以熟期组Ⅰ组(吉育97、吉育89、绥农28、绥农35)、Ⅱ组(吉育82、吉育92、辽豆21、辽豆32)、Ⅲ组(中黄35、冀豆21、邯豆7、沧豆5)的12个大豆品种为试验材料,研究4个播期(6月16日、6月26日、7月4日、7月14日)对不同熟期组大豆产量及相关性状的影响。结果表明:随播期推迟,生育期、株高、主茎节数、单株荚数、单株粒数、单株粒重出现一定程度降低,且差异显著(P<0.05),百粒重无显著差异(P>0.05);熟期组Ⅲ组大豆的产量降低,熟期组Ⅱ组和Ⅰ组大豆的产量先升高后降低。在4个播期中,以熟期组Ⅲ组大豆冀豆21、邯豆7在播期6月16日的产量最高,分别为4 410.4kg/hm^2和4 329.0kg/hm^2。The effects of four different sowing dates (16, June, 26, June, 4, July and 14, July) on yield and relative traits of 12 soybean varieties from Group I (Jiyu 97, Jiyu 89, Suinong 28 and Suinong 35), Group II (Juyu 82, Juyu 92, Liaodou 21 and Liaodou 32) and Group III (Zhonghuang 35, Jidou 21, Handou 7 and Cangdou 5) were studied to provide the basis for popularization and application of soybean varieties with different maturity in Cangzhou, Hebei. Results: The growth period, plant height, node number, pods/plant, grains/plant and grain weight/plant reduce with delay of sowing date to some extent and there are significant differences(P〈0.05)in these traits among three groups. There is no significant difference in 100-grain weight among three groups. The yield of Group III reduces with delay of sowing date but the yield of Group I and Group II presents a first rising and then declining trend with delay of sowing date. The highest yield of Jidou 21 and Handou 7 sowing on 16, June reaches 4 410.4 kg/hm^2 and 4 329.0 kg/hm^2 respectively in four sowing dates.
