不同播期和优化施肥对高油大豆产量及品质的影响

Effects of Different Planting Dates and Optimum Fertilization to Yieldand Quality of High Oil Soybean

不同播期和优化施肥对高油大豆产量和品质的影响试验结果表明，适期播种有利于提高大豆品质和增加产量；优化施肥，即适量少施氮、增施磷钾锌硼肥，可提高大豆产量和油分含量。适量少施氮，可增加大豆产量136．5kg／hm^2，增加油分0．25个百分点；增施磷钾肥，大豆产量增加148．5～277．5kg／hm^2，油分增加0．11～0．54个百分点；增施锌硼肥，大豆产量增加184．5～216．0kg／hm^2，油分增加0，34～0．43个百分点。

The studies on effects of planting dates and optimum fertilization to yield and quality of high oil content soybean variety were conducted. The results showed that suiable planting date could increase yield and improve quality. The optimum fertilization, namely, applying a little amount of nitrogen fertilization can increase soybean yield 136.5 kg/hm^2 and oil content 0.25 percent, potassium and phosphor fertilization can increase soybean yield 148.5 - 277.5 g/hm^2and oil content 0. 11 - 0.54 percent, zinc and boron fertilization can increase soybean yield 184.5 - 216.0 kg/hm^2 and oil content 0.34 -0.43 percent.
