- 摘要:
- 以合丰50为材料,分7个播期、5个密度,研究不同播期及密度对其品质、产量及农艺性状的影响。结果表明:播期及密度对高油高产大豆品种合丰50的产量有较大的影响,随播期的延迟和密度的增加,该品种的产量呈先上升后下降的变化趋势,差异达到极显著水平;播期对油份含量的影响较大,而且规律性极强,即随播期的延迟各密度处理合丰50的油份含量下降。不同密度处理对油份含量的影响较小,而且规律性也不强。合丰50的最佳播种时期为5月9日左右,而最适密度为25万株.hm-2,此时可获得最高产量和较高的含油量。
- Abstract:
- New soybean variety Hefeng 50 was used to study the response of oil content and yield to different sowing dates(25th April,2nd May,9thMay,16thMay,23thMay,30thMay,6thJune)and densities(20,25,30,35 and 40 104plants ha-1).Results showed that sowing dates and densities had great influence on yield of Hefeng 50,with the sowing date delayed and density increased,the yield of Hefeng 50 showed increase-and-then-decrease trend,and significant difference were observed among treatments;sowing dates had significant influence on oil content,with the sowing date delayed,the oil content decreased regularly;planting densities had no obvious influence on oil content.Results suggest that under the planting density of 25×104plants.ha-1and the sowing date of 9thMay,soybean variety Hefeng 50 had highest yield with higher oil content.
