摘要
研究容器苗施肥方案,其结果是马尾松速生期肥料比例,N、P、K为3∶2∶1,即Co(NH2)21 600 mg/L、Ca(H2PO4)24 000 mg/L、K2SO4800 mg/L,生长后期以3∶2∶2为佳,在苗龄40 d开始施肥。华山松生长期肥料比例以N、P、K为3∶2∶2,即Co(NH2)21 600 mg/L、Ca(H2PO4)24 000 mg/L、K2SO41 660 mg/L,在苗龄40 d开始施肥。
The fertilization technique for container seedlings of Pinus massoniana and Pinus armandi was reported in this paper. The suitable fertilizer combination ratio of Nitrogen, Phosphate and Potassium for mason pine growth was 3 : 2:1 (N : P: K), or Co(NH2)2 1600mg/L、Ca(H2PO4)2 4000mg/L、KSO4 800mg/L, While for Pinus armandi, 3:2:2(N: P: K), or Co(NH2)2 1600mg/L、Ca(H2PO4)2 4000mg/L、K2SO4 1660mg/L. The appropriate time of initiate fertilization for both pine species was 40 days after seed germination.
