摘  要：
为降低苗木种植成本,本研究选用蘑菇渣、泥炭土、椰糠、锯木糠、珍珠岩和马占相思林下表土等基质,按不同体积比配成12种育苗基质进行银叶金合欢优质壮苗培育试验。结果表明:12种不同配比的育苗基质容重均显著低于对照,最大持水量、毛管孔隙度、总孔隙度和有机质含量均显著高于对照;T4、T5、T6、T74种基质培育的苗木保存率、净高生长量、根系中根瘤数、苗木干物质质量和地下部分根系干质量等生长指标优于对照;以V(蘑菇渣)∶V(珍珠岩)∶V(林下表土)为1∶2∶1(T5)基质培育的苗木表现最好,其苗木保存率、苗木净生长量、根系中根瘤数量、苗木干物质质量和地下部分根系干质量较对照提高了15%,126.4%,3 465.2%,631.6%和525.4%,并与对照存在显著差异。

摘  要：
In order to save the transportation cost,12 mixed substrates were made up respectively,on basis of different ratios of mushroom residue,peat soil,sawdust,perlite and subsoil of Acacia mangium forest. Results indicated that unit weight of 12 mixed seedling substrates was significantly lower than control group. Maximum water holding capacity,capillary porosity,total porosity and organic matter content were significantly higher than those of control group. Seedlings grew from T4,T5,T6,T7 substrates,the survival rate,height growth,root nodule number,dry weight of seedling and root were better than that of control group. Compared with control group,seedlings grew from T5(V(mushroom residue) ∶ V(perlite) ∶ V(forest soil) = 1 ∶ 2 ∶ 1) showed optimal performance,survival rate,net growth of seedling,number of root nodule dry weight of seedling and root significantly increased by15%,126. 4%,3 465. 2%,631. 6% and 525. 4%,respectively.
