一、树胚的选择 1.要求树胚新鲜,不能严重脱水。鉴别的方法,可在树根和树干上,用指甲或硬物轻轻划开树皮表层,划出时无硬感,划开后呈粉红色或青色并有湿润感,证明水份尚存,是刚挖出不久的新鲜树胚。反之可能已经严重脱水。如已经脱水,种植前应在水中浸泡1～2小时后再种,可提高成活率。 2.树胚主要部位要有健壮的芽眼。健壮的芽眼,以明显鼓胀为特征。这种芽眼,萌发力强,抽芽快、生长迅速而且健壮。芽眼稳约可见的,也可选用,但萌发较慢。
First, the choice of embryo 1. Requires fresh embryo, not a serious dehydration. Identification method can be in the roots and tree trunks, with a nail or hard objects gently cut open the surface of the bark, no hardship when strung out, after the opening was pink or blue and a sense of moisture to prove that water still exists , Is just scoop up fresh embryo. On the contrary may have been severely dehydrated. As already dehydrated, before planting should be immersed in water for 1 to 2 hours before planting, can improve the survival rate. 2. The main parts of the embryo should have robust bud eye. Robust bud eye, characterized by marked bulging. This bud eye, strong germination, sprouting fast, rapid growth and robust. Steady eye bud visible, can also be used, but the germination is slow.
