播种基质与催芽方法对迎红杜鹃出苗率的影响试验

以迎红杜鹃种子为材料,采用双因素4次重复随机排列试验设计进行了不同播种基质和不同催芽方法对播种出苗率的影响试验.结果表明,不同基质与不同催芽方法以及二者的交互作用对迎红杜鹃播种出苗率均有显著影响.其中,以播种基质为腐殖土与沙混合,比例为2∶1,上面再铺一层1 cm厚粉碎的旱苔藓,催芽方法为播种前10d混湿沙,种沙比为1∶6,置于温室或小拱棚内摊开,每天翻动2次并适时喷水这个组合出苗率最高.

Influence of Different Substrates and Different Methods of Germination on Seeds Emergence of Rhododendron mucronulatum

Research on the seeds of Rhododendron mucronulatum with different substrates and different methods of germination is conducted. The results of seeds emergence showed that different substrates, different germination methods and also the interactive effect can obviously influence the seeds emergence of Rhododendron mucronulatum. The substrate is made by mixing budding soil corrosion with sand by 2 ： 1, above with a layer of lcm thick dry moss. The Germination method is mixing wet sand 10 d before planting, the ratio of seeds and sand is 1 ： 6, placed inside the greenhouse or spreaded in a small shed, turning 2 times a day and timely water. This combination has the highest germination rate.
