为加速海棠百日苗(苹苗砧)的粗生长,当年培育成苹果苗,我们在田洼林场用木架塑料棚进行育苗试验。当年七月初,幼苗地径0.8厘米,进行了芽接,成活率90%,缩短了两年苗的留圃期。一、种子处理育苗前半月,种子用凉水浸一天,然后与湿沙拌匀。种子和湿沙的比例为1∶3。堆放在室内,室温15～20℃。每天翻搅2次,浇水1～2次。保持湿润,待种子个别裂口即可播种。
In order to speed up the crude growth of Begonia seedlings, seedlings of apple seedlings were cultivated in that year and we used nursery plastic sheds to carry out nursery experiments in Tianwa Forest Farm. Early July of that year, the seedling diameter 0.8 cm, budding, the survival rate of 90%, shortened two years of nursery leave nursery period. First, the seed treatment Before the first half of nursery seed, soak the seeds with cold water for one day, then mix well with wet sand. The ratio of seed to wet sand is 1: 3. Piled in the room, room temperature 15 ~ 20 ℃. Turn 2 times a day, watering 1 ~ 2 times. Keep moist until the seed can be sown individual cracks.
