圣诞树组培苗移植试验

摘要

运用正交试验的方法研究不同炼苗时间、遮阳网遮光率、基质以及不同移植月份对圣诞树组培苗移植效果的影响.结果表明,炼苗时间为10d、遮阳网遮光率为70％、基质为泥炭土∶黄心土(2∶1)、移植月份为4月的处理圣诞树移植效果最好,成活率可达97.2％,苗高达11.1 cm.%Using orthogonal test, effects of different refine seedling time , different shading rate, different substrate , and different transplanted months on transplanted affects of tissue culture seedling of Metrosideros excelsa was analyzed in this paper, the results indicated that the best conditions for transplanted affect; time of refine seedling is 10 days , the shading rate of shade-net is 70% , the substrate is proportioning of peat soil, yellow soil =2: 1 , the transplanted month is April , the survival rate can reach to 97. 2% , and the height of seedling reach to 11. lcm.
