以枳幼苗为试材,采用容器育苗法,按体积比配制5种基质:A(CK1),V_(河沙)∶V_(锯木屑)=1∶2;B(CK2), V_(河沙)∶V_(锯木屑):V_(草炭)=1∶2∶1;C,V_(河沙):V_(锯木屑)∶V_(生物碳)=1∶2∶0.1;D,V_(河沙)∶V_(锯木屑)∶V_(生物碳)=1∶2∶0.3;E,V_(河沙)∶ V_(锯木屑)∶V_(生物碳)=1∶2∶0.5,研究基质中添加生物碳对枳生长的影响。结果表明,生物碳呈碱性,pH值高达8.96,可用于提高基质的pH值,生物碳中含P、K较为充足,N较少;生物碳能有效提高基质的持水量、pH值、矿质元素含量,降低基质的容重,增加非毛管孔隙度,但对基质的电导率及阳离子交换量影响不明显;将枳砧幼苗移植到添加生物碳的基质中,研究发现...

In this experiment, five substrate formulas with sand, sawdust, peat and bio–charcoal were conducted to study the effect of bio–charcoal on the growth of Poncirus Trifoliata (L.) Raf. with container nursery. The results showed that the bio–charcoal was alkaline, its pH was as high as 8.95 and could be used to improve pH of mix substrates. It was rich in P and K and lack of N. The bio–charcoal could effectively improve the water holding capacity, pH and mineral elements content, reduce bulk density and increase the capillary porosity in mix ...
