摘要
为了提高栽培大豆的蛋白质含量,寻找最佳的播种时期,满足黑龙江垦区生产高蛋白大豆的需要,利用3个黑龙江省东部主栽的高蛋白大豆品种黑农48、黑农43和东农42,进行8个播期栽培试验,探讨播期对高蛋白大豆农艺性状、产量及蛋白质含量的影响。结果表明:播期对高蛋白大豆的成熟期无影响,而对生育期有影响,大豆生育期因播期推迟而缩短;播期对高蛋白大豆的农艺性状有影响但差异不显著,提早或延迟播期使单株有效荚数、单株粒数减少,百粒重减小;播期对高蛋白大豆的产量有影响且差异显著;播期对高蛋白大豆的蛋白质含量有影响,播期越晚蛋白质含量越低,但各播期间差异不明显。在黑龙江东部地区高蛋白大豆的适宜播期是5月8日至5月14日。
Suitable sowing date would enhance yield and quality of crops. In order to sufiqce the needs of production on high protein soybean in Heilongjiang Reclamation Area, three major high protein soybean varieties of Heinong 48, Heinong 43 and Dongnong 42 in the eastern part of Heilongjiang Province were adopted and eight sowing date experiments from 2nd May to 23th May was conducted. The effect of sowing date on growth period,yield and protein content were determined. Results showed that mature date of high protein soybean was consistent but growth duration was shortened as the delaying of sowing date;Agronomic traits was affected by sowing dates but the difference Wash' t significant. Early or late sowing decreased number of effective pod ,seed number per plant and 100-seed weight. Sowing date have significant influence on yield. Protein content similarly was affected by sowing dates but difference wasn't significant,the later the sowing time,the lower the protein content. Results suggest the suitable sowing date of high protein soybean is from May 8 to May 14 in the eastern part of Heilongjiang Province.
