摘要
在中性紫色土上,大豆适宜的土壤氯浓度为100～600ppm,耐氯临界值为600～700ppm。其成熟期茎杆含氯1.14%,叶含氯为3.78%,豆荚含氯为1.02%,根含氯为0.274%,籽粒含氯为0.147%,在此范围内不影响大豆的产量和品质。
The critical value of Cl tolerance of soybean is 600 to 700 ppm in the neutral purple soil. The suitable Cl concentration of the soil is 100 to 600 ppm. Correspondingly, in the mature period, the Cl contents of the stalk, leaf, pod, root, weed are 1.14%, 3.78%, 1.02%, 0.27%, 0.15% respectively. In the above range, the yield and the quality of soybean are not affected by Cl.
