本试验以苗龄为65d的日本北海道特产小果树HASKAOP带根组培苗为材料,研究不同栽培基质、炼苗方式、移栽季节,以及使用不同激素对小果树移栽成活的影响。结果表明:最适合小果树的栽培基质是蛭石:草炭=1:1,成活率为59.0%,新叶数可达3.34片,且植株健壮、叶色正常;采用炼苗方式三时,小果树组培苗的成活率最大为65.0%,比不经炼苗成活率提高52.0%;春季是最适宜小果树组培苗的移栽季节,成活率达62.0%;移栽前使用100mg/L ABT的成活率比空白对照组仅提高5.3%,且其他种类激素的使用对提高小果树组培苗成活率无明显效果。
In this study, HASKAOP rooted tissue culture seedlings of HASKAOP, a small fruit tree with a seedling age of 65d, in Hokkaido, Japan, were used as materials to study the effect of different planting media, the way of seedling, the season of transplanting and the transplanting of small fruit trees with different hormones. The results showed that the most suitable medium for small fruit trees was vermiculite: peat = 1: 1, the survival rate was 59.0%, the number of new leaves was up to 3.34, and the plants were robust and leaf color was normal. The survival rate of tissue culture seedlings was 65.0%, which was 52.0% higher than that of non-harvested ones. Spring was the most suitable transplanting season for tissue culture of small fruit trees with a survival rate of 62.0%. Before transplanting, 100mg / L ABT survival rate increased by only 5.3% compared with the blank control group, and the use of other types of hormones to improve the survival rate of small fruit tree tissue culture seedlings no significant effect.
