摘要
旨在确定探明不同高蛋白大豆品种的最佳播期。本试验以黑龙江省三江平原主栽的4个高蛋白大豆品种分7个播期进行栽培,研究了播期对高蛋白大豆品质及产量的影响。结果表明:4个高蛋白大豆品种在各播期蛋白质含量均值变化范围为39.14%~45.26%,最大变化幅度为15.64%;脂肪含量均值变化范围为18.82%~20.30%,最大变化幅度为7.86%;产量变化范围为2064.2~3068.1 kg/hm^2,蛋白质产量均值变化范围为807.2~1377.9 kg/hm^2,产量和蛋白质产量均随播期变化呈先增高后降低的趋势,并在A2播期达到最大值,播期显著影响大豆蛋白质含量、脂肪含量、产量和蛋白质产量。因此,适期播种能够提高大豆产量和蛋白质产量,适合当地高蛋白大豆品种的最佳播期是5月4日左右。
The aim is to study the optimal sowing date of different high-protein soybean varieties. 4 highprotein soybean varieties in Sanjiang Plain of Heilongjiang Province were used as materials, 7 different sowing dates were carried out in this study. The effects of the sowing date on seed quality and yield of high protein soybean were studied. The results showed that: the mean rang of protein content of the 4 high-protein soybean varieties was from 39.14% to 45.26%, and the maximum change was 15.64%. The mean range of fat content was from 18.82% to 20.30%, and the maximum change was 7.86%. The yield variation range was from^2064.2 kg/hm^2 to 3068.1 kg/hm^2. The mean protein yield range was from 807.2 to 1377.9 kg/hm^2. Yield and protein yield increased first and then decreased with the sowing dates, and reached the maximum at A2 sowing date. The sowing date significantly affected the protein content, fat content, yield and protein yield of soybean.Therefore, the optimum sowing date can increase yield and protein yield of soybean, and the best sowing date in local climatic condition for high-protein soybean varieties is around May 4.
