北疆芦竹的扦插快繁技术

芦竹（Arundodonax）属禾本科芦竹属多年生粗壮草本植物，又称荻芦竹，是介于芦苇与竹子之间的1种非木材纤维原料，分布于温、热带地区。对土壤要求不严格，河堤碱地均可种植，而且生长在水边地带还可以净化污水。芦竹的繁殖力强，其繁殖方法有分株繁殖、扦插繁殖等。分株繁殖成活率高，但繁殖系数太低，且植株大小不一，生长不一致；扦插繁殖系数高，但成活率受扦插技术和环境影响较大。芦竹在新疆北部是稀有的绿化材料、主要用于水景园的背景材料，也可点缀于桥、亭、榭四周，也是北疆难得造纸材料，在滴灌条件下可保证芦竹喜水的特性，加之北疆光照充足，

Taking Ganoderma and Rubus idaeus L.as materials,the culture medium and fermentation conditions of Ganodermabefore extraction of total flavnoid fromRubus idaeus L.were optimized through the L18(37)orthogonal experimental design.The results showed that the optimal medium composition(g/L)were Glucose 20g/L,Oybean powder 15g/L,Corn flour 50g/L,Yeast extract 1.0g/L,KH2 PO4 0.6g/L,MgSO4 ·7H2 O 0.2g/L,VB1 0.01g/L;under these conditions,the content of total flavonoids was 4.58mg/g,which revealed a 96.57%increase compared with the control group(without the inoculation of Ganoderma).
