时下正是繁殖杜鹃的大好季节,笔者通过多年实践,总结了一套比较理想的扦插方法,操作简单,成活率高,可以达到基本无死苗的良好效果。扦插时机的掌握在自然条件下,室外温度在20～30℃时为最佳时机(北方大约在5月下旬至6月)。此时气温升高,雨水增多,湿度加大,是扦插杜鹃生根的最理想的自然条件。而且,当年生枝条已饱满充实,这时扦插生根快、成活率高。扦插基质的配制为保证成活率及成活后对养分的需要,可用腐烂或半腐烂的松毛、木渣(4:6)混合而成。使用前用浓度500～1000倍的多菌灵或甲基托布津水溶液喷洒,静置1～2天。扦插容器的选择我体会,塑料泡沫盒子(如蛋糕盒等)比较合适,取用方便,保温性能又好。选好
Nowadays it is an excellent season for breeding rhododendrons. After years of practice, the author has summarized a set of ideal cutting methods, which has the advantages of simple operation and high survival rate, and can achieve good effects of basically no dead seedlings. Cutting timing to master the natural conditions, the outdoor temperature of 20 ~ 30 ℃ is the best time (northern about late May to June). At this point the temperature increases, the rain increased, humidity increases, is the best cutting Rhododendron natural conditions. Moreover, when the branches have been full full, then cutting rooting fast, high survival rate. The preparation of cutting matrix To ensure the survival rate and survival after the need for nutrients, available rotten or semi-rotten pine, wood residue (4: 6) mixed. Before use with a concentration of 500 to 1000 times the carbendazim or thiophanate-methyl spray solution, let stand 1 to 2 days. I choose to cut the selection of containers, plastic foam boxes (such as cake boxes, etc.) more appropriate, easy to use, good thermal insulation properties. Selected
