摘要
以珍贵乡土树种大叶桂樱1 a生容器苗为试材,分析不同浓度的Cu试剂、Zn试剂、Al试剂、氟乐灵和乙烯磷对大叶桂樱1 a生容器苗根系、株高、地径、叶片数的影响。结果表明:浓度为150 g/L CuCO3可显著缩短一级侧根平均长度,增加一级侧根数,对地上部分影响较显著;浓度为200 g/L CuCO3已对根系造成毒害;一定浓度范围的ZnCl2和AlCl3对主根、地径、苗高、叶片数影响较显著;除0.20 g/L乙烯磷对根系造成伤害外,不同浓度氟乐灵和乙烯磷对容器苗各项指标影响不明显。
Analyze different concentrations of Cu reagents,Zn reagents,Al reagents,Trifluralin and Forestenon on large root,height,ground diameter,leaf number of annual container seedlings of Prunus zippeliana.The results showed that concentrations of 150 g/L CuCO3 can significantly shortened the average length of primary lateral root,increased primary lateral root number,and significantly effected the Aerial parts;200 g/L CuCO3 caused the root poisoned;Certain concentration range of ZnCl2and AlCl3 effected the main root length,base diameter,plant height,leaf number significantly;The effect of different concentrations of Trifluralin and Forestenon on container seedlings was not obvious.
