金针菜的无性繁殖

金针菜又称黄花菜，是多年生宿根草本植物。种植几年以后．其地下部分就发育成庞大株丝(俗称“蔸”)，深蔸按照自然分蘖，连根用手一株株掰开．就是一株独立的种苗。用种苗进行栽种，生产上称无性繁殖；金针菜无性繁殖的方法大体有以下四种。

δ^13C and water-use efficiency indicated by δ^13C of different plant functional groups on Changbai Mountains,Northeast China

Leaf δ^13C of different plant functional groups （trees, shrubs and forbs; evergreen and deciduous; annual, biennial and perennial） were examined on the Changbai Mountains, China. Life form has a significant influence on plant δ^13C, suggesting that leaf δ^13C is also ideal for distinguishing functional groups species in temperate and frigid zones with high humidity. Additionally, the difference of water-use efficiency （WUE） is significant among different plant functional groups. δ^13C and WUE are in the following order of forbs 〈 shrubs 〈 trees. Within shrubs, δ^13C and WUE are higher for evergreen shrubs than deciduous shrubs. Differences in δ^13C and WUE are significant among different lifespan herbs, and δ^13C and WUE follow the order of annual herbs 〉 biennial herbs 〉 perennial herbs, not in accordance with the pattern obtained by previous studies in deserts, suggesting that the ranking of δ^13C and WUE among annual, biennial and perennial herbs may be dependent on local water availability.

浅谈假俭草在厦门的养护

厦门地区气候特征:厦门位于东经118°04′04″,北纬24°26′46″,地处福建省东南部九龙江人海处,背靠漳州、泉州平原,濒临台湾海峡、与台湾本岛和澎湖列岛遥遥相对。属亚热带气候,温和多雨,年平均气温在21℃左右。夏无酷暑,冬无严寒。年平均降水量在1200毫米左右,5-8月份雨量多,风力一般3-4级,常向主导风力为东北风。由于太平洋温差气流的关系,每年平均受4-5次台风的影响,且多集中在7-9月份。
