| 摘 要： | 该文通过试验研究了气象条件 (CO2浓度、温度、土壤湿度) 变化对小麦叶片、茎、籽粒中量元素 (Mg、Ca、S) 和微量元素 (Zn、Fe) 含量及产量的影响。结果表明:高CO2浓度、土壤干旱胁迫对这5种元素含量积累有利; 高CO2浓度伴随高温缩短了小麦生育期, 使籽粒产量明显下降, 综合中量元素和微量元素含量的有利影响和产量的不利影响, 要想获得正常气象条件下等量的5种元素, 小麦的供给量将会是短缺的。

| Abstract: | Through experiment, the impacts of meteorological conditions on the contents of middle elements (Mg, Ca, S) and trace elements (Zn, Fe) for wheat leaves, st alks and grains, and yield are studied. The results show that the high CO 2 con ce ntration and water stress are favorable to the accumulation of the 5 elements. H igh CO 2 concentration accompanying with high temperature will shorten the growth period and decrease the number of grains. Synthesizing the positive effect of m iddle and trace elements and the negative effect of yield, the amount of wheat s upply will run short if the same trace elements as in normal meteorological cond ition are required. |
