摘  要:
对基地不同程度缺钙症状的烤烟植株的组织分析结果表明,烟株叶片反转卷曲的畸形症状的程度与叶片内钙含量呈反相关,而与烟叶内硫酸根离子和磷的含量呈正相关。基地新垦红壤中只是因为使用商品有机肥1号才有大量的硫酸根和磷酸根可供烟株吸收。水培试验结果证明,高浓度的磷酸根离子能够诱导烟株缺钙的症状,营养液中钙浓度越低,磷酸根浓度越高,诱发的烟叶缺钙的症状出现时间越早,程度越严重。从而证明基地出现的因施用商品有机肥1号而诱导烤烟缺钙症状的机理确是由于该有机肥所含的大量磷酸根、硫酸根等阴离子与根际土壤中的钙形成溶解度更低的硫酸钙盐或磷酸盐的沉淀,因此阻碍了Ca2+的吸收,以及烟株大量吸收磷酸根和硫酸根导致体内钙的转运和再利用困难所致的。

摘  要:
Tissue analysis of flue-cured tobacco plants with different degrees of calcium deficiency sampled from the tobacco production base located in Southwest China show that the symptom of calcium deficiency on tobacco plants was mitigated with increasing Ca concentration in the leaves,but aggravated with increasing SO2-4 and PO3-4 concentrations in the leaves.Results of the hydroponic experiment indicated that high PO3-4 concentration in the solution could induce symptom of calcium deficiency on tobacco plants.The greater the PO3-4 concentration in the solution,the earlier the occurrence of the symptom,and the more serious the symptom.These findings revealed that serious calcium deficiency of tobacco plants in the production base resulted from application of the commercial organic manure containing high concentrations of SO2-4 and PO3-4,which reduced solubility of Ca in the rhizosphere,thus hindering uptake and transport of Ca2+ by the plants.
