2002年我所养的雌性苏铁首次开花,经过授粉,收获了近400粒种子,由于以前没有种子育苗的经历,所以我查阅了相关资料,找到4篇种子育苗的文章,归其要点:1、把种子橘红色的外种皮清除掉。2、用高锰酸钾或多菌灵进行消毒处理。3、用沙藏法进行催芽处理。4、用敲击法进行破壳处理。当年12月,我采用前3项措施对这批种子进行处理,首先除去外种皮(图1)集中盆播,打算等发芽后重新定植,基质为珍珠岩,放在室内(最低温度1℃以上)。2003年3月,将花盆搬到光照良好的平房顶上,并用塑料薄膜覆盖,4月上旬有少数种子已破壳裂口(图2)。5
For the first time in 2002, the female cyclamen we raised had pollinated and harvested nearly 400 seeds. Due to the lack of seedling experience in the past, I consulted the relevant materials and found 4 articles on seedling raising, with the following main points: Remove the seed orange-red outer skin. 2, with potassium permanganate or carbendazim for disinfection. 3, sand method for germination treatment. 4, using the percussion method for broken shell processing. In December of that year, I used the first three measures to deal with the seeds, first removing the seed coat (Fig. 1) and concentrating the seedlings and planting to re-plant after germination. The substrate was perlite and placed indoors (minimum temperature 1 ℃ the above). In March 2003, the pots were moved to the top of well-lit flat houses and covered with plastic film. In early April a handful of seeds were broken by the shell (Figure 2). 5
