研究了缺锌溶液培养对番茄 (Lycopersiconesculentummiller)和甜椒 (Capsicum frutescensL .Var.grossumBailey)两种蔬菜生长发育及磷、钾、钙、锌在植物体内各部位含量的影响 ,结果表明 :两种蔬菜叶部缺锌症状的出现与叶的含锌量关系并不大 ,而与叶的含磷量和含钙量密切相关 .叶部缺锌症状的出现 ,主要是由于叶内磷的过度积累产生的毒害作用和叶内钙含量的大幅度降低产生的有害影响 ,以及钾含量的降低造成离子平衡失调的结果 ,而供锌不足造成叶含锌量降低的直接作用并不是主要的 .
The effects of zinc deficiency solution on the growth and development of two vegetable species (Lycopersicon esculentummiller and Capsicum frutescensL.Var.grossumBailey) and the content of phosphorus, potassium, calcium and zinc in different parts of the plant were studied. The results showed that: The appearance of zinc deficiency in leaves is not related to the content of zinc in leaves, but closely related to the content of phosphorus and calcium in leaves. The appearance of zinc deficiency in leaves is mainly due to the excessive accumulation of phosphorus in leaves And the deleterious effects of a significant reduction in leaf calcium content, as well as the detrimental Imbalance of ion balance caused by a decrease in potassium content, whereas the direct effect of a deficient supply of zinc on the reduction of leaf zinc content is not significant.
