采用4因素4水平正交试验,研究了品种、密度、施肥水平、播期对高油大豆光合生理及产量的影响.结果表明:品种、密度、施肥水平、播期4因素通过影响高油大豆的叶面积指数、光合势、叶绿素含量的动态变化,进而影响高油大豆的产量.其中叶面积指数和光合势随着密度和施肥水平的升高呈上升趋势,随着播期的延迟而下降,而叶绿素含量则随着密度的升高而降低,但随着施肥水平的升高和播期的延迟呈上升趋势;施肥水平对高油大豆的产量影响最大,其中农大15751在5月3日播种,施肥量为300 kg·hm-2,密度为45 ×104plants·hm-2时产量最高,达3788 kg·hm-2.
Effect of Cultivation Practice on Photosynthetic Physiology and Yield of High-Oil Soybean
The effect of variety,planting density,fertilizer level and sowing date on photosynthetic physiology and yield of high-oil soybean was studied by field experiment. Results showed variety,density,fertilizer level and sowing date affected the yield of high- oil soybean by influencing the dynamics leaf area index (LAI), leaf area duration (LAD) and chlorophyll content. LAI and LAD showed increase trend with increasing of density and fertilizer,while showed decrease trend with the delaying of sowing date. Chlorophyll content decreased with the increasing of density,while increased with the increasing of fertilizer and the delaying of sowing date. Among the four factors,fertilizer levels affected the yield of high-oil soybean greatly. For example, Nongda 15751 got highest yield of 3788 kg · ha -1 when planted on May 3 with the fertilizer level of 300 kg · ha -1 at the planting density of 45 × 104 plants · ha -1.
