摘要:
以小麦品种良星99为材料，采用长期定位大田试验田研究了5个不同施氮水平下各个时期小麦植株的锌营养状况和氮素调控对植株锌转运与分配的影响。结果表明，增加施氮量显著提高小麦植株在各生育期锌的含量和累积量，在不同器官中锌含量和锌累积量均随施氮量的增加而提高。在收获期，锌主要集中在籽粒中，约占植株锌累积量的70%，茎和叶中比例依次下降。施氮量对锌的收获指数及开花后锌的转运量没有显著影响。在优化施氮水平处理下，小麦籽粒锌含量超过40 mg/kg，达到了以小麦为主要粮食作物的人群锌营养和健康要求的范围。
Abstract:
In the long-term field experiment, LX99 was used as the material to study the effects of under five zinc nutritional status and nitrogen regulation in wheat plants at different stages on zinc transport and distribution under five nitrogen levels. The results showed that zinc content and accumulation of wheat plants at all growth stages were significantly increased by increasing nitrongen application rate. The content and accumulation of zinc in different organs of wheat increased with the increase of nitrogen application rate. At the harvest stage, zinc was mainly concentrated in grains, accounting for about 70%, followed by stems and leaves. However, nitrogen application rate had no significant effect on zinc harvest index and zinc transport after flowering. The content of zinc in wheat grain under the optimal nitrogen application level was more than 40 mg/kg, which met the requirements of zinc nutrition and health for the population with wheat as the main food.
