不同苗质与移栽条件对新丰生姜组培苗成活率的影响

将新丰生姜组培苗按不同苗质与移栽条件组合成24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6.25%，蛭石与草炭土1：1的比1：2和1：3的分别高6.25%和14.06%。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100%。

Effect of different seedling quality and transplanting conditions on transplanting survival rate of tube-plantlets of Xinfeng ginger

Tube-plantlets of Xinfeng ginger were combined into 24 treatments of different plantlets quality and transplanting conditions. The results showed stronger seedling, hardening plantlets, carrying rooting powder, and 1: 1 of vermiculite and turfy-soil benefit to transplanting survival rate. 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 plantlets is best to raise transplanting survival rate. The optimal treatment are both stronger plantlets and hardening plantlets，which survived at 100%.
