For the results of field investigation, the nitrate pollution is not serious, the rest meet with the criterion expect for celery and radish, but the nitrate content of some kinds in leaf vegetables and root vegetables seem to be close to the criterion. 从田间调查的结果来看,依据河北省无公害蔬菜硝酸盐最高限量标准,蔬菜硝酸盐污染问题并不严重仅西芹和大白萝卜(富春)超标,其余的蔬菜均符合标准。
The Zn contents of different parts of celery increased with Zinc fertilizer application. The amount of absorption was root> leaf> leafstalk. The Zinc concentration was leaf> root> leafstalk. 芹菜各部位含锌量随施锌量增加而增加,增加速度依次为根>叶>叶柄,而含锌浓度依次为叶>根>叶柄。
The results showed that the competence of formation of the callus and embryonic callus from hypocotyl of celery decreased with its relative position from leaf end to apex of root. 结果表明,荷兰芹下胚轴胚性发生能力随其相对位置而异,自下而上逐渐提高。
The increase in the biomass of celery in eutrophic water was in no relation to the nutrient concentration of the tested water. Root growth was in inverse correlation to the nutrients concentration. 芹菜在富营养化水体中生长时生物量增加倍数与受试水样中营养物质浓度的高低没有相关性,根系生长与其呈负相关。
The Zi Jinsha alias white root angelica, turns the celery, for umbelliferae, when the ownership plant turns the celery Angelica polymorpha Maxim. dry root. 紫金砂别名白根独活、拐芹,为伞形科当归属植物拐芹AngelicaPolymorphaMaxim.的干燥根。
