分别采用充分腐熟后的松针粉、松树皮粉、锯木屑、稻谷壳粉、竹叶粉为主要基质成分与腐殖土、松林表土、火土灰、黄心土、过磷酸钙混合组成 30个配方基质。通过对苗高、地径、总鲜重、总干重、根干重、地上干重 /地下干重 6项指标进行方差分析和多重比较 ,30个配方基质中 ,以稻谷壳粉 (50 ) +腐殖土 (10 ) +松林表土 (2 0 ) +火土灰 (10 ) +黄心土 (10 ) +过磷酸钙 5% ;稻谷壳 (4 0 ) +腐殖土 (2 0 ) +松林表土 (2 0 ) +火土灰 (10 ) +黄心土 (10 ) +过磷酸钙 5% ;松皮粉 (50 ) +腐殖土 (10 ) +松林表土 (2 0 ) +火土灰 (10 ) +黄心土 (10 ) +过磷酸钙 5%等配方基质苗木生长最好
Pinellock powder, pine bark powder, sawdust, rice hull flour and bamboo leaf powder were used as the main matrix components and mixed with humus soil, pine forest topsoil, fire earth ash, yellow heart soil and superphosphate respectively to form 30 formulation matrices . The variance analysis and multiple comparisons were made on six indexes of seedling height, diameter, total fresh weight, total dry weight, root dry weight, above ground dry weight / underground dry weight. Among the 30 formula bases, + Humus (10) + pine forest topsoil (20) + fire ash (10) + yellow heart soil (10) + superphosphate 5%; rice hull (40) + humus soil (20) + fire earth ash (10) + yellow heart soil (10) + superphosphate 5%; pine powder (50) + humus soil (10) + pine forest top soil + Huang heart soil (10) + superphosphate 5% and other formula substrate seedlings grow best
