摘　　要：研究了不同覆土厚度、不同肥料对辽东山区白桦播种育苗的影响。结果表明:不同覆土厚度对白桦出苗率和保存率存在影响,3mm(53.05%、50.14%)>6mm(44.75%、41.63%)>10mm(13.45%、10.14%)>15mm(3.35%、2.97%)>20mm(1.15%、1.00%)。不同施肥方法对白桦播种育苗平均苗高、平均地径的影响:硫酸铵(0.87m、0.53cm)>磷酸氢二铵(0.82m、0.49cm)>过磷酸钙(0.75m、0.45cm)>对照未施肥(0.58m、0.38cm)。覆土厚度3mm时,出苗快而齐,施硫酸铵的苗木质量最好。The effects of different covering soil thickness and fertilizing method onseedling raising of Betula platyphylla in eastern mountainous of Liaoning Province were studied.The results show thateffects ofdifferent covering soil thickness on seedling emergence rate and preservation rate of Betula platyphylla:3 mm(53.05% 、50.14%)>6 mm(44.75%、41.63%)>10 mm(13.45%、10.14%)>15 mm(3.35%、2.97%)>20 mm(1.15%、1.00%).Effects of different fertilizing method on average seedling height and average ground diameter of Betula platyphylla:Ammonium sulfate(0.87 m、0.53 cm)>Diamine hydrogen phosphate(0.82 m、0.49 cm)>Calcium superphosphate(0.75 m、0.45 cm)>Control without fertilization(0.58 m、0.38 cm).When the thickness of soil cover is 3 mm,the seedlings emerge quickly and evenly,and the quality of seedlings treated with ammonium sulfate is the best.
