不同苗质及移栽条件对新丰生姜组培苗成活率的影响

Effect of Different Seedling Quality and Transplanting Conditionson Transplanting Survivalrate of Tube-plantlets of Xinfeng Ginger

将新丰生姜 (ZingiberofficinaleRosc .)组培苗按不同苗质与移栽条件组合成 2 4种处理。移植结果表明 ,壮苗、炼苗、蘸生根粉和蛭石与草炭土 1∶1有利于新丰生姜组培苗移栽后的成活。在各种组合中 ,壮苗的平均成活率比弱苗高 8 33%,炼苗的平均成活率比不炼苗的高18 75 %,蘸生根粉的平均成活率比不蘸生根粉的高 6 2 5 %,蛭石与草炭土 1∶1的比 1∶2和 1∶3的分别高 6 2 5 %和 14 0 6 %。炼苗提高移栽成活率的作用最大 ,壮苗和炼苗的组合结果最好 ,移栽成活率可达 10 0 %。

Tube-plantlets of Xinfeng ginger (Zingiber officinaleRosc.)were combined into 24 treatments ofdifferent plantlets quality and transplanting conditions. The results showed stronger seedling, hardening plantlets, carrying rooting powder, and 1∶1 of vermiculite and turfy-soilbenefit to transplanting survivalrate.Among the treatments, The average percentage of stronger seedling was 8.33% higher than weaker seedling, hardening plantlets 18.75% higher than not hardening plantlets, carrying rooting powder 6.25% higher than not carrying rooting powder, 1∶1 of vermiculite and turfy-soil 6.25% higher than 1∶2 and 14.06%higher than 1∶3. To harden plantletsis best to raise transplanting survivalrate. The optimal treatment are both stronger plantletsand hardening plantlets,which survived at 100%.
