摘要
油菜在中性紫色土上的耐氯临界值为400～600ppm。在0～400ppm氯水平时,油菜生长正常,800ppm以上生长受到抑制,1600ppm时出现氯中毒症状,至3200ppm时,症状严重,显症时间亦最早。
In the nentral purple soil the critical value of chlorine tolerance of rape is 400 ppm to 600 ppm. At the level of Cl concentration from 0 to <400 ppm, the rape grows normally over 800 ppm, its growth is restrained. The Cl toxicty symptom occurs when the Cl concentration at 1600 ppm is added to the soil. Up to 3200 ppm, the symptom occurs most severely and early.
