瑞香扦插繁殖,成活率低、时间长、长根量差。为此,我们用吲哚丁酸(IBA),以不同的浓度加适量的酒精来探索瑞香扦插繁殖的最佳途径。用材和方法:1.介质和插床。采用有全日照喷雾的砂床,砂床宽为1.2米,砂床底铺透水性良好的小石子及煤渣,然后上铺厚度为30厘米的粗砂。2.插条选用当年生长成熟半木质化的枝条,长5～8厘米,叶片保留3～5片,每处理为20枝。3.植物生长调节剂吲哚丁酸(IBA),加浓度为50％酒精,分别配成,
Ruixiang cutting propagation, low survival rate, long time, the amount of long-root difference. To this end, we use indole butyric acid (IBA), with different concentrations of appropriate amount of alcohol to explore the best way to cuttings of Daphne fortunei. Materials and methods: 1. Media and slotting. A full sun spray sand bed, sand bed width of 1.2 meters, sand bed bottom shop with good permeability of pebbles and cinder, and then the thickness of 30 cm on the grit. 2. Cuttings used to grow mature half-lignified branches, 5 to 8 cm long, leaves 3 to 5, each treatment is 20. 3. Plant growth regulator indole butyric acid (IBA), plus the concentration of 50% alcohol, were dubbed,
