Six Vegetables, namely tomato, cucumber, French bean, radish, Spinach and Chinese cabbage, were irrigated with Petrochemical wastewater containing Phenols and aromatic hydrocarbons and treated with biochemical process. it was found that there were no disadvantageous effects on the growth, Yield and quality of the experimental vegetables. the residues of phenols and aromatic hydrocarbons in edible portions of the vegetable crops as well as in the soil. were indistinct.

利用生化处理石油化工含酚和芳烃混合废水,灌溉了番茄、黄瓜、菜豆、萝卜、菠菜和白菜等6种蔬菜,经过观察,对以上蔬菜的生长、产量和品质均没有不良影响。在蔬菜可食部分和土壤中,酚和芳烃的残留量不明显。而未经生化处理的废水,不仅抑制蔬菜生长、降低产量(菜豆除外),而且使品质变劣,不能食用;在蔬莱可食部分和土壤中,酚和芳烃均有明显的积累。未作处理的废水经4倍稀释后,对黄瓜主根伸长有明显阻碍。所以,引用石油化工废水灌溉蔬菜,必须实行无害化处理(如生化活性污泥法)。

Effects of nitrate and nitrite on vegetable growth were investigated by solution culture in different proportions of NO_3-N and NO_2-N (12:0, 8:4, 4:8, 0:12mM)and different pH value (7, 6, 5).Tomato, euettmber, cabbage and pak choi were used as material. Results indicated that these vegetables can obviously divide into two types: 1. tomato and pak choi were sensitive to nitrite toxicity and lower the pH value the more serious of the toxic effect is. 2. cucumber and cabbage were not very sensitive to the nitrite...

Effects of nitrate and nitrite on vegetable growth were investigated by solution culture in different proportions of NO_3-N and NO_2-N (12:0, 8:4, 4:8, 0:12mM)and different pH value (7, 6, 5).Tomato, euettmber, cabbage and pak choi were used as material. Results indicated that these vegetables can obviously divide into two types: 1. tomato and pak choi were sensitive to nitrite toxicity and lower the pH value the more serious of the toxic effect is. 2. cucumber and cabbage were not very sensitive to the nitrite toxicity. Accumulation of nitrate and nitrite in plants would be increased when concentration of nitrate and nitrite in solution were increased. Leaf vegetables accumulated more nitrate and nitrite then fruit vegetables. If a large amount of NO_2-N was applied, unnormal accumulation of individual amino acid would be resulted in causing the metabolic disturbance of nitrogen in the vegetables. The most accumulation of amino acids was THR in tomato and ASP in pak choi.

以番茄、黄瓜、甘蓝和小白菜为材料,用营养液栽培法研究了不同硝酸态氮(NO_3-N)与亚硝酸态氮(NO_2-N)配比(NO_3-N:NO_2-N分别为12:0,8:4,4:8,0:12mM),不同pH值(pH7、6、5三组),对蔬菜生长和NO_3-N,NO_2-N、游离氨基酸累积的影响。结果表明,这四种蔬菜明显地分为两类:番茄、小白菜易感受NO_2-N的危害,并且有随溶液中pH值的下降而受害加剧的趋势;而黄瓜和甘蓝则对NO_2-N具有较强的耐受性。供试植株内NO_3-N与NO_2-N的累积量,随营养液中硝酸盐及亚硝酸盐的浓度增大而增加。叶莱较果菜易于累积NO_3-N与NO_2-N。大量施用亚硝酸态氮肥,会导致蔬菜内个别氨基酸的异常积累,引起氮素代谢的紊乱。番茄积累最多的是苏氨酸,小白菜为天门冬氨酸。

The influence of soil lead on the growth of radish, Chinese cabbage and lettuce was studied. The growth of the vegetable was stimulated by soil lead at low concentration and the critical levels at which the vegetable yield was reduced 10 percent were 400-500mg/kg for radish and Chinese cabbage and 200mg/kg for lettuce as 0.5M BaCl2 extracted lead. The results also showed that the soil lead content was significantly correlated to the plant uptake of lead and the lead accumulation coefficients of edible tissues...
