This Paper describes a diffusion method to seperate fluorinc of plant ma-terial directly from other interferring ions for its determination.After wash-ing with tap water, plant samples were dried at 85℃ for 24-48 hrs.,milledand passed through a 100 mesh sieve.Put the dried powder into a small sty-rene plastic round vessel,o.d. 6cm and 2cm high,with tight cover.Put thesample in the central part at thc bottom, and keep it free from the side wallof the vessel, otherwise, the diffusion process may be affected, Wetting with2ml distilled water, mixing with 2 ml 70% perchloric acid,and put on the co-ver, which has a thin layer of NaOH formed by spreading 0.2 ml IN NaOHin ethyl alcohol on the inner surface.Put the vessel under 50℃±1℃ anddiffusion for 18-20 hrs. At end of the diffusion the diffusate was dissolvedwith H_2O from the cover,the fluorine content was determined by alizarincomplexone spectrophotometrically. The recovery of fluorine from standard NaF solution,either witn or withoutplant samples,is higher than 95%.Experimental error of this method comparedwith that of ashed at 550℃ after adding Mg(NO_3)2, is less than 5%,thatproves this method is satisfactory. Using this method we have determined the F content of leaf, bark andfruit samples from forest and fruit trees,vegetables and farm crops.we aresatified witn our data.

本文报导了用扩散法直接从植物样品中分高氟,以除去干扰离子。样品用水冲洗后,在85℃干燥24—48小时,磨碎后过100目筛。样品放在聚苯乙烯塑盒(外径为6厘米、高2厘米)的底部,先用2毫升蒸馏水湿润,然后加入2毫升70%高氯酸,摇匀并盖好,盖的内面涂有1N NaOH乙醇溶液0.2毫升,干燥后使用。扩散条件:温度50℃±1℃,时间为18—20小时。扩散后,用菌素酪合酮分光光度法测定含氟量。 结果表明,标准氟化钠在有无植物样品时回收率均高于95%;直接扩散与加Mg(NO_3)_2在550℃灰化后扩散相比较,两者误差一般不超过±5%。我们用此方法测定了多种树木、果树、蔬菜和农作物的叶片、树皮和果实较为满意。

The Nanshan Mountain is the largest pasture in southern China,with a total area of 138,345mu(9,223 ha).According to the principle of ecology physiognomy,its vegetation can be divided into 10 main types.They are evergreen needleleaf forest;mixed evergreen and deciduous broadleaf forest;deciduous broadleaf forest;bush-wood;bamboo thicket;grassland; swampland;cropland;economic forest and fruit trees.The natural vegeta- tion belongs to mixed evergreen and deciduous broadleaf forest or deciduous broadleaf and low montane forest.The present grassland was created by forest fires and felling of forest communities,i.e.,unstable secondary vegetation. It follows that in the exploitation and utilization of nature resources on the Nanshan,forestry should play an important role and graziery should be combined with forestry.On slopes of over 35 degrees, forestry must be developed,and on those of 25—34 degrees consideration must be given to both forestry and pasturage,while on those under 24 degrees pasturage may be developed and all kinds of shelter-forest must be planted.

城步南山是我国南方规模最大的牧场,总面积138,345亩(9,223公顷)。南山地区的植被,根据生态外貌原则划分为常绿针叶林、常绿落叶阔叶混交林,落叶阔叶林,灌丛、竹丛、草丛,农作物,经济林和果园等10个主要类型。现在的草丛是森林遭受破坏的次生植被。本区在开发利用上,应以发展林业为主,实行林牧结合。山地坡度大于35°的必须发展林业,25—34°的坡地要林牧兼顾,小于24°者可以发展牧业,并营造各类防护林。
