- Several views about sand culture research
关于沙文化研究的几点认识 - The results showed that 5406 actinomyces can improve the wheat seedling ' s height , root system and stalk leaf weight , can increase content of chlorophyll and root system activity in sterilized sand culture
结果表明，经5406放线菌处理后小麦幼苗株高、根长、根体积、根系及茎和叶片干重、叶绿素含量及根系活力均有不同程度的提高。 - A survey of literature shows that little study has been done on uptake of pollutants by plants from the polygonaceae , and that the reports about their physiological and biochemical characteristics under heavy metal stress were sporadically seen . a batch of sand culture and soil culture experiments were carried out to investigate heavy metal and radiocesium uptak e and accumulation by rumex acetosa linn , polygonum microcephalum d . don , and rumex hastatus d . don widely distributed on copper mining areas , and their physiological and biochemical characteristics under cu zn stress , as well their potentials in application to phytoremediation
本论文以广泛生长于铜矿区的蓼科植物酸模、小头蓼和戟叶酸模为试验材料，运用砂培、土培等方法，研究它们对重金属( cu 、 zn )以及放射性核素( ~ ( 134 ) cs )的吸收和积累特性以及cu 、 zn胁迫条件下它们的生理生化特征，初步探讨它们在无机污染物污染土壤植物修复中的应用潜力。 - Effect of napthalene ( nap ) and pyrene ( pyr ) different concentration on hypocotyl germination of kandelia candel in sand culture is obvious . hypocotyl germination of kandelia candel showed no significant difference from control group at concentration of 0 . 1mg / l for nap and pyr . when at concentration of 1 mg / l and 10mg / l , nap showed a significant inhibition on hypocotyl germination of k . candel , but showed no inhibition on first pair of leaves ; at concentration of 10mg / l , nap showed a significant inhibition on the second pair of leaves
Nap浓度为0 . 1mg l对秋茄种苗萌发的影响不明显；在1mg l浓度组对秋茄种苗初期萌发阶段即吐芽有明显的抑制作用，而对第一对叶片和第二对叶片展开影响不明显；在10mg l浓度组对种苗吐芽以及第一对叶片展开没有明显影响，而对第二对叶片展开有明显的抑制作用。 - This finding may bring a hope to phytoremediate as - contaminated soils . the effects of as and ca on the growth of p . vittata l . and as uptake by p . vittata l . were studied under sand culture condition . the interaction of as and ca on concentration and distribution of metals including k , mg , mn , fe , zn and cu in it were also investigated
通过砂培盆栽试验，本论文从砷和钙的作用对蜈蚣草生长和累积砷的影响及砷、钙与其他必需金属元素的关系等方面研究了蜈蚣草的营养特性，从砷、钙、磷的亚细胞定位探讨了蜈蚣草对砷的解毒机理及钙的作用机制。
