紫金牛扦插育苗技术

The cutting propagation technique of Ardisia japonica

按不同扦插基质、生长调节剂和木质化程度等不同因素进行紫金牛扦插生根率、插穗生根质量Q测定。结果表明,草炭∶河沙(V∶V=1∶1)扦插生根率达94.5%,是最理想的扦插基质;质量浓度为300 mg/L的IBA处理插穗的生根质量最高,生根率达到96.9%;半木质化的插穗生根率明显高于嫩枝和全木质化。

The rooting rate and rooting quality of cutting shoots of Ardisia japonica were studied based on substrate, growth promoting agents and wooden degree. The results indicated that peat and sand（ V： V = 1：1 ） was the best rooting substrate for Ardisiajaponica. The cutting rooting rate was 94.5% ;the rooting quality dealing with the 300 mg/L IBA was the best （96.9%） ;the rooting rate of half wooden cutting shoot was higher than that of wooden shoot.
