You will come in May between June, between choice section shorter give birth to half lignification branch in those days, from base the ministry cuts dirty to insert spic, topmost reservation comes 3 pieces 5 flocculus, if branch is too long, yi Ke bite off carries a tip on the head, cuttage medium can use humus soil of orchid mud, high mountain, vermiculite, pearlite or Huang Xin earth to wait, thick about 15 centimeters reach 20 centimeters, the catchment layer that lower berth reachs 8 centimeters 7 centimeters; medium after in season is wet, in will inserting spic to insert matrix, deepness of the be buried that insert spic makes an appointment with the 1/2 that grows for spic, a few cuttage also can choose the family full-dress medium generation makes big flowerpot cuttage seedbed.

你可于5月至6月间，选择节间较短的当年生半木质化枝条，自基部切下作插穗，顶端保留3片至5片小叶，若枝条过长，亦可截去顶梢，扦插介质可用兰花泥。高山腐殖土。蛭石。珍珠岩或黄心土等，厚约15厘米至20厘米，下铺7厘米至8厘米的排水层；把介质喷湿后，将插穗插入基质中，插穗入土深度约为穗长的1/2，家庭少量扦插也可选用大花盆盛装介质代作扦插苗床。插后加盖塑料薄膜保湿，温度控制在25℃至30℃之间，加设荫棚遮挡阳光，或挪放于树荫下，始终保持扦插基质湿润，东鹃约过1个月即可生根，而西鹃则要60天至70天才能生根。9月后可减少遮荫时间，并追施稀薄尿素液一次，浓度约为0.2%，10月下旬即可上盆。

Result indicated that:(1) Different ground substance has effection ,taixian is the best one for rooting.
