不同基质对扶芳藤扦插育苗的影响

[目的]研究扶芳藤扦插育苗的最佳基质配比。[方法]采用5种基质配比,分别为M1(50%泥炭+50%珍珠岩)、M2(40%泥炭+60%珍珠岩)、M3(50%泥炭+50%栗钙土)、M4(40%泥炭+60%栗钙土)、M5(100%泥炭)对扶芳藤进行容器扦插育苗试验,对不同基质引起的扶芳藤愈伤率、生根率、根长、单株根系数目、新生枝数及新生枝生长量进行调查分析,[结果]结果表明,基质M1中扦插的扶芳藤生根率、愈伤率最高,分别为87%和88%;根长最长,为68.0 mm;平均新生枝数最多,为4.6条,效果最佳。基质M5中扦插的扶芳藤,其单株根系数目最少,为43.1条;新生枝生长量最高,为12.7 cm;基质M4最差。[结论]基质M1与M5比较适合扶芳藤插穗的生长。

Impact of Different Matrices on Euonymus fortunei Cutting

[Objective] The best ratio of matrix for Euonymus fortunei cutting was researched.[Method] 5 matrices: M1(50% peat + 50% perlite),M2(40% peat + 60% perlite),M3(50% peat + 50% chestnut soil),M4(40% peat + 60% chestnut soil) and M5(100% peat) used for Euonymus fortunei cutting in container were tested and the effect of the different matrices on the rate of callus induction and root growth,the length and number of root,and the growth amount of Euonymus fortunei was investigated.[Results] The results showed that the best effect on Euonymus fortunei cutting was from the M1,in which,the rate of root growth,callus induction,the length of root and the number of new branch were 87%,88%,68.0 mm and 4.6 branches,respectively.In M5,the number of root per plant was the least(43.1) and the growth amount of new branch was the highest(12.7 cm).The effect of M4 on Euonymus fortunei cutting was the worst.[Conclusion] M1 and M5 were suitable for the growth of Euonymus fortunei cutting.
