Abstract:
In order to make scientific fertilization scheme for farmers planting polygala tenuifolia in southern Shanxi province,a field test was conducted through two-years.The split-plot design was adopted to study the effects of different fertilization depths and amounts on the aboveground productivity,root yield of polygala tenuifolia, and soil physical and chemical properties.The main plot was the fertilization depth,with two levels,30 cm(D1) and 15 cm(D2),split plot was the fertilization amount,with four levels,450(F1),600(F2),750(F3),and 900(F4)kg?hm-2.The results showed that D2 had significant advantages over D1 in plant height and root yield,and root yield was increased by 2.67%.The yield,diameter,weight,dry bark weight and wood core diameter of polygala root under fertilization treatments were F2>F3>F1>F4,and root length was F2>F4>F3>F1.D1 could significantly reduce soil bulk density.The contents of available nitrogen,phosphorus and potassium increased with the increase of fertilizer application.D1 (15 cm) plus F2 (600 kg?hm-2) would be appropriate.
