| 摘 要： | 采用4因素3水平的正交试验设计,研究了配方施肥对八角幼林产量、树高、冠幅和地径的影响。经直观分析和方差分析进行综合评价,结果表明,八角幼林产量最佳施肥比例是K2B1N3P3即(氯化钾250g·株-1、硼肥25g·株-1、尿素489.1g·株-1、钙镁磷肥833.3g·株-1),树高增长最佳施肥比例是N3K2P2B2即(尿素489.1g·株-1、氯化钾250g·株-1、钙镁磷肥555.6g·株-1、硼肥50g·株-1),冠幅增大最佳施肥比例是N3P3K2B1即(尿素489.1g·株-1、钙镁磷肥833.3g·株-1、氯化钾250g·株-1、硼肥25g·株-1),地径增粗最佳施肥比例是K3P3B3N1即(氯化钾375g·株-1、钙镁磷肥833.3g·株-1、硼肥75g·株-1、尿素163g·株-1)。

| Abstract: | Using four factors and three levels of orthogonal experimental design,the influences of formulated fertilization on the yield,growth of tree height,canopy width and ground diameter of the young plantation of Illicium verum were studied.Visual and variance analyses were adopted to carry out comprehensive evaluation.The results showed that the best fertilization ratio on promoting the yield was K2B1N3P3(potassium chloride 250 g,boric fertilizer 25 g,urea 489.1 g,and calcium magnesium phosphate 833.3 g per plant).The best fertilization ratio on promoting the growth of tree height was N3K2P2B2(urea 489.1 g,potassium chloride 250 g,calcium magnesium phosphate 555.6 g,and boric fertilizer 50 g per plant) The best fertilization ratio on promoting the growth of ground diameter was N3P3K2B1(urea 489.1 g,calcium magnesium phosphate 833.3 g,potassium chloride 250 g,and boric fertilizer 25 g per plant).The best fertilization ratio on promoting the growth of canopy width was K3P3B3N1(potassium chlorice 375 g,calcium magnesium phosphate 833.3 g,boric fertilizer 75 g,and urea 163 g per plant). |
