摘要
在昆明树木园所进行的连香树、多果槭、榉树、枫杨和川滇桤木等5个乡土绿化阔叶树种不同育苗基质的当年育苗效应试验的结果表明:在其当年生苗木的苗高、地径和冠幅3个性状上,与对照红壤育苗基质相比,不同育苗基质对此5个乡土绿化阔叶树种当年生苗木的苗高、地径和冠幅生长的作用不一,红壤4+福贝菌2育苗基质(处理A)和(复合肥2 kg+钙镁磷肥2 kg)/100 kg红壤育苗基质(处理C)对5个乡土绿化阔叶树种当年生苗木的生长均具有促进作用,对连香树、多果槭、榉树和川滇桤木等4个阔叶树种的当年生苗木生长具较佳促进作用的育苗基质是处理A,其连香树当年生苗木的苗高、地径和冠幅分别比对照高34.04%、15.00%和15.38%;多果槭当年生苗木的苗高、地径和冠幅分别比对照高70.55%、23.81%和39.18%;榉树当年生苗木的苗高、地径和冠幅分别比对照高31.93%、35.33%和33.33%;川滇桤木当年生苗木的苗高、地径和冠幅分别比对照高101.65%、38.27%和50.63%。而促进枫杨当年生苗木生长的较佳育苗基质是处理C,其当年生苗木的苗高、地径和冠幅分别比对照提高44.30%、23.55%和30.93%。
The experiments of nursery medium of five broad-leaved tree species namely Cercidiphyllum japonicum,Acer prolificum,Zelkova schneideriana,Pterocarya stenoptera and Alnus cremastogyne cv.yanshan,Cercidiphyllum japonicum,were carried out in Kunming arboretum.The experimental results showed that compared with the control（red soil as medium）,tested medium formulation had different effects on the performance of seedling on height,basal diameter and crown diameter.Treatment A（red soil and microbial strain Faby of the proportion of 4 to 2） and treatment C（compound fertilizer 2kg ＋ calcium magnesium phosphate fertilizer 2kg）/100 kg red soil） can promote the growth of tested seedlings.Formulation A is the optimum medium for Cercidiphyllum japonicum,Acer prolificum,Zelkova schneideriana and Alnus cremastogyne cv.yanshan,Cercidiphyllum japonicum grew in medium A had the height,basal diameter and crown diameter 34.04 %,15.00 % and 15.38 % higher than the control respectively.And that of Acer prolificum in medium A were 70.55 %,23.81 % and 39.18 % higher than the control.The values for Zelkova schneideriana were 31.93 %,35.33 % and 33.33 % in order,and 101.65 %,38.27 % and 50.63 % respectively for Alnus cremastogyne cv.yanshan.The optimum formulation for Pterocarya stenoptera was treatment C,the seedling height,basal diameter and crown diameter were 44.30 %,23.55 % and 30.93 % higher than the control.
