摘　　要：以黑龙江北部的44份大豆品种为试验材料,设置4个播期处理(SD1~SD4),研究播期对黑龙江北部大豆品种生育进程、产量及品质相关性状的影响。结果表明,随播期延迟,营养生长阶段和生殖生长阶段均显著缩短,生殖生长提前,生育进程加快,生育期逐渐缩短;随播期推迟,株高、底荚高、有效分枝数、主茎节数、单株荚数、单株粒数、百粒重和小区产量均呈先略增加后显著降低趋势;播期对品质影响不同,蛋白质含量先显著升高后显著下降,脂肪含量呈显著下降趋势,且随播期间隔延长,不同播期品种品质相关性降低,SD1和SD4处理参试品种的品质相关性不显著;筛选出较稳定的高蛋白品种龙垦310和华疆5号,高油品种九研9号和黑科58号。筛选出SD3处理较稳产的品种龙垦310、龙达167、圣豆37和佳豆36;筛选出SD4处理较稳产的品种贺豆6和富豆15。A total of 44 soybean varieties in northern Heilongjiang were used as materials and four treatments(SD1-SD4)were set to study the effects of sowing date on growth process,yield and quality related traits in northern Heilongjiang.The results showed that with the delaying of sowing date,vegetative growth stage and reproductive growth stage were significantly shortened,reproductive growth was advanced,the growth process was accelerated,and the growth period was gradually shortened.With the delaying of sowing date,plant height,bottom pod height,effective branch number,main stem node number,pod number per plant,seed number per plant,100-grain weight and plot yield increased slightly first and then decreased significantly.The effect of sowing date on quality was different.The protein content first increased significantly and then decreased significantly,and the fat content showed a significant trend of decline.With the extension of sowing interval,the quality correlations of different sowing dates decreased.The qualities of the tested varieties in SD1 and SD4 treatments were significantly not correlated.The stable high-protein varieties Longken 310 and Huajiang 5,and high-oil varieties Jiuyan 9 and Heike 58 were screened.The stable yield varieties Longken 310,Longda 167,Shengdou 37 and Jiadou 36 in SD3 treatment,and Hedou 6 and Fudou 15 in SD4 treatment were selected.
