不同栽培基质对非洲菊组培幼苗移栽成活率和生长的影响

以非洲菊组培试管苗为试材。蛭石、珍珠岩、炭化稻壳、草炭土以不同的比例配成7种栽培基质,分别是A1(蛭石)、A2(珍珠岩)、A3(炭化稻壳)、A4(草炭土)、A5(1/2蛭石 1/2珍珠岩)、A6(1/2蛭石 1/2草炭土)、A7(1/3珍珠岩 2/3草炭土),进行非洲菊试管苗移栽基质的筛选试验。定期观测成活率、长势、平均株高及生长指标,地上部和地下部鲜重、干重,分析比较7种基质配方中对非洲菊试管苗移栽质量的影响。结果表明,非洲菊试管苗移栽基质以在A4(草炭土)、A7(1/3珍珠岩 2/3草炭土)的基质中生长较好最佳,其次,为A3(炭化稻壳)基质,但A3(炭化稻壳)成本较低,且较容易获得。

Effect of Different Mediums on Survival Rate and Growing Situation of Gerbera jamesonii Tissue Culture Seedling after Transplanting

This paper took Gerbera jamesonii as trial sample and the vermiculite,pearlite,char rice husk,grass charcoal soil are mixed into seven kinds of culture mediums in the different proportion,including A1(vermiculite),A2(pearlite),A3(char rice husk),A4(grass charcoal soil),A5(1/2 vermiculite 1/2 pearlite),A6(1/2 vermiculite 1/2 grass charcoal soil),A7(1/3 pearlite 2/3 grass charcoal soil).Survival rate,growing situation,the fresh weight and dry weight on the ground and underground were observed,and the effect of the 7 kinds of mediums on the tissue culture seedling after transplanting were compared and analyzed.The result indicated A4(grass charcoal soil) and A7(1/3 pearlite 2/3 grass charcoal soil) are the best,A3(char rice husk) is better,but cost of A3(char rice husk) is relatively low,and easier to get.
