摘要
在中性紫色土上,萝卜适宜的土壤浓度为100～50ppm,耐氯临界值为700pom。相应,茎叶含氯为2.11～7.03%,肉质根含氯为0.912—2.530%,在此范围内不影响萝卜的产量和品质,而且氯使萝卜中硝态氯的含量降低,有助于改善品质。
The critical value of Cl tolerance is 700 ppm in the neutral purple soil. The suitable Cl concentration of the soil is 100 to 500 ppm. Correspondingly, the Cl contents of the stalk and the leaf are 2.11 to 7.03%, and the Cl contents of taproot are 0.912 to 2.53%. In the above range, the yield and the quality of radish are not affected by Cl, and Cl can make the NO_3-N content of taproot reducing, thus, the quality of taproot is improving.
