樟树扦插试验研究

母树年龄(A)、扦插月份与方法(D)、生长激素(B)对扦插生根率有极显著或显著影响影响,激素浓度(C)对试验结果影响不显著,试验处理的最佳组合是A1B3C3D2;处理组合03、02、07、06号是优良组合类型,平均生根率在79.3%～94.3%之间;08、05、10、16、11、13、14、15号是最差组合类型,平均生根率≤10.0%;扦插苗根系远优于实生苗,其处理组合03、02、07、06、09号的根系指数较实生苗的根系指数均有极显著或显著差异.

Study on Cutting Propagation of Cinnamomum camphora

In order to require cutting nursery stocks with fine root,the experiments by Cinnamomum camphora′s cutting showed that the factor A,D and B had very significant or significant obvious effects on rooting ratio of their cutting nursery stocks,and factor C had not obvious effects,the best union of experiment treatment should be A1B3C3D2;03,02,07 and 06 were types of excellent treatment union,whose mean rooting ratio were 793%~943% and 08,05,10,16,11,13,14,15 were types of the worst treatment union,whose mean rooting ratio were no more than 100%;their roots of cutting nursery stocks were much better than that of seedling,root index of 03,02,07,06,09 had very significant or significant obvious differences than that of seedling
