“苹果”枣试管苗移栽基质研究

Study on transplanting media of plantlets of Chinese date of ' Pingguo'in vitro.

该试验采用两步移栽法,即首先将试管内生根苗移栽到育苗盘中过渡培育一段时间,然后再将成活的移栽苗移入容器杯中.当苹果枣组培苗在试管内生根时,使其闭口炼苗10～15d后,移栽于纯蛭石,蛭石/珍珠岩=1/2,蛭石/珍珠岩=1/1,蛭石/珍珠岩=2/1,纯珍珠岩5种不同移栽基质的育苗盘中.调查结果表明,选用纯珍珠岩和蛭石/珍珠岩=1/2的移栽基质,可以显著地促进移栽试管苗的高生长、新发根数量以及移栽成活率.随后将在移栽盘中过渡移栽成活的试管苗栽入腐殖土/蛭石/土=1/2/1,腐殖土/纯沙/蛭石=1/1/2,火烧土/珍珠岩=1/1,火烧土/蛭石=1/1,纯沙/蛭石=1/1,腐殖土/蛭石=1/1,腐殖土/珍珠岩=1/1共7种不同移栽基质的容器杯中.调查结果以腐殖土/蛭石/土=1/2/1和腐殖土/珍珠岩=1/1为基质的处理对栽入容器杯的苗高生长和移栽成活率有显著的促进作用.

Plantlets were transplanted into plate with 5 different kinds of transplanting media that were vermiculite, vermiculite/perlite=1/2, vermiculite/perlite=1/1, vermiculite/peiiite=2/1 and perlite. The result showed that: transplanting media of perlite and vermiculite/ perlite=1/2 could significantly increase the plantlets height, rooting and survival rate. Seedlings were transplanted into container with 7 different kinds of transplanting media that were humic soil/vermiculite/soil=1/2/1; humic soil/sand/vermiculite=1/1/2; calcined clays/perlite=1/1; calcined clays/vermiculite=1/1; sand/vermiculite=1/1; humic soil/vermiculite=1/1 and humic soil/perlite=1/1. The best transplanting media for the seedlings high growth and survival rate were humic soil/vermiculite/soil=1/2/1 and humic soil/perlite=1/1.
