通过无土栽培试验,测定番茄各个时期叶片中Ca、Mg、Fe、Mn、Cu、Zn的含量,旨在发现番茄各时期矿质元素的吸收规律.结果表明:用不同基质配方栽培,除Mg以外,番茄叶片中其他元素的含量没有极显著性差异.番茄叶片中的Ca元素在整个生长期内呈先下降后迅速升高的趋势,最高出现在移栽后180 d,为18.410 1 mg·g~(-1),最低出现在移栽后60 d,为4.789 8 mg·g~(-1); Mg元素含量在波动中上升,最高出现在移栽后180 d,为30.515 1 mg·g~(-1),最低出现在移栽后60 d,为12.637 8 mg·g~(-1);Fe呈上升趋势,最高出现在移栽后240 d,为0.478 7 mg·g~(-1),最低出现在移栽后60 d,为0.193 8 mg·g~(-1);Mn元素含量在波动中上升,最高出现在移栽后240 d,为65.942 9 μg·g~(-1),最低出现在移栽后,为40.928 6 μg·g~(-1);Cu元素含量先迅速下降,后迅速上升,最高出现在移栽后300 d,为13.785 7 μg·g~(-1),最低出现在移栽后240 d,为5.3143 μg·g~(-1);Zn元素含量呈先升高、后降低、后期又升高的趋势,最高出现在移栽后120 d,为116.8 μg·g~(-1),最低出现在移栽后240 d,为26.357 μg·g~(-1).

In order to discover the law of absorbing of inorganic nourishment of tomato growth in soilless culture, the Ca, Mg, Fe,Mn,Cu and Zn concentration on tomato leaf were measured in different stages. The consequence was that there was no obvious variation of these elements in different stage, except Mg. The result was that the accumulative trend of Ca was decreased, then increasing quickly. The highest content of Ca was 18.410 1 mg·g~(-1) after plant out 180 days; the lowest was 4.789 8 mg·g~(-1) after plant out 60 days. The accumulative trend of Mg was increased fluctuant. The highest content of Mg was 30.515 1 mg·g~(-1) after plant out 180 days; the lowest was 12.637 8 mg·g~(-1) after plant out 60 days. The accumulative trend of Fe was increased. The highest content of Fe was 0.478 7 mg·g~(-1) after plant out 240 days; the lowest was 0.193 8 mg·g~(-1) after plant out 60 days. The accumulative trend of Mn was increased fluctuantly. The highest content of Mn was 65.942 9 mg·g~(-1) after plant out 240 days; the lowest was 40.928 6 mg·g~(-1) after plant out. The accumulative trend of Cu was decreased quickly, and then increasing quickly. The highest content of Cu was 13.785 7 mg·g~(-1) after plant out 300 days; the lowest was 5.314 3 mg·g~(-1) after plant out 240 days. The accumulative trend of Zn was increased, then decreasing, and finally raised. The highest content of Zn was 116.8 mg·g~(-1) after plant out 120 days; the lowest was 26.357 mg·g~(-1) after plant out 240 days.
