摘  要：
试验于2009年在辽宁省农业科学院试验基地进行。在田间条件下,通过测定不同施肥处理的群体叶面积、各器官的风干重以及生物产量和籽实产量,探讨叶面积指数动态、光合势、生物产量积累动态与产量形成的关系,为合理施肥和提高向日葵产量提供依据。结果表明:增施氮、磷、钾肥,配施硼肥,可显著影响向日葵生理指标和产量。F3和F6的LAImax分别为3.86和4.12,高于对照F7(3.70)。F3和F6的光合势相应为1 393 750和1 449 750 m2.d,明显高于对照F7(1 258 250 m2.d)。其最大积累速率的出现时间分别为67.1和64.1 d,明显长于对照F7的55.4 d。F3和F6最大积累速率(12.21和12.14 g.株-1.d-1)明显高于其它处理。最终生物产量和经济产量都最高:F3为8 330.42和2 918.33 kg.hm-2;F6为8 504.58和2 965.0 kg.hm-2。

摘  要：
The experiment was conducted to observe the effect of nitrogen,phosphorus,potassium and boron application amount on the growth and yield of sunflower at Liaoning Academy of Agricultural Sciences in 2009.The results indicated that increasing N,P,K and B fertilizer would improve the growth and yield significantly of sunflower.The highest leaf area index of F3(3.86) and F6(4.12) were higher than that of F7(CK 3.70),respectively,the leaf area duration(LAD) of F3 and F6 at growing season were 1 393 750 and 1 449 750 m2·d,higher than that of F7(1 258 250 m2· d).The time of highest biological yield accumulation rates of F3 and F6 were 67.1 d and 64.6 d after sowing,later than that of F7(55.4 d),the highest dry matter accumulation rates of F3 and F6 were significant higher than others,then the dry matter and yield were the highest.
