怎样辨别杜仲雌雄株 ○靳振宇 据观察同一杜仲林地内,当雄株占十分之一以上时,即可以达到良好的授粉目的。因此,在扦插育苗和嫁接时,应从雌雄单株上按照9:1的比例来采集插穗和接穗。在采集嫩枝插(接)穗时,可通过花、芽、果、皮孔分布等来判断雌雄株。 雌株:枝条比较稠密,树冠开张,树皮皮色秃白,皮孔少而稀。皮孔排列较整齐,叶芽瘦长,发芽晚;已结实树在冬季枝条往往具有当年或多年宿存的果实。 How to identify Eucommia male and female plants ○ Jin Zhenyu It is observed within the same Eucommia, when the male plant accounts for more than one-tenth, you can achieve a good purpose of pollination. Therefore, cuttings and grafts should be harvested from male and female plants at 9: 1 cuttings and scions. In the collection of shoots inserted (pick) spike, through flowers, buds, fruit, leather hole distribution to determine the male and female. Female plants: more dense branches, the crown opened, bark pale skin, lenticels few and thin. Lenticules arranged neatly, leaf buds elongated, sprouting late; already strong trees in winter branches often have the fruit of the year or years.
