摘要
选用6种育苗基质对白及苗进行育苗试验,为培育壮苗提供参考.对各生长指标的测定分析表明,苗高、地径、叶片数、叶长、叶宽、须根数在5个月后的均值分别达到32.9 cm,3.08 mm,4.9片,24.7 cm,1.78 cm,30.2条;最适合白及苗木苗期生长的基质是腐殖土,而V(河沙)∶V(柴皮)=1∶1,V(河沙)∶V(锯末)=1∶1,V(红土)∶V(柴皮)=1∶1,V(红土)∶V(锯末)=1∶1,这几种育苗基质也比较适合白及苗根、茎、叶的生长;单纯的红土效果较差,不适合作为白及的育苗基质.
In order to provide a reference for cultivating strong seedling,6 different substrates were tested for seedling raising experiment of Betilla striata.The measurement and analysis of each growth index shows that seedling height,ground diameter,number of leaves, length of leaf,width of leaf,number of fibrils reaches 32.9 cm,3.08 mm,4.9 pieces,24.7 cm,1 .78 cm,30.2 pieces after 5 months’ growth.The most suitable substrate for the growth of seeding of Bletilla striata is muck.Substrates (river sand and tree bark (1 ∶1 ),riv-er sand and sawdust (1 ∶1 ),red soil and tree bark (1 ∶1 ),red soil and sawdust (1 ∶1 )are also more suitable for the growth of its leaf, stem and root.The effect of pure red soil was poorer,and it is not suitable for substrate of Bletilla striata growth of second stage.
