摘要：

通过田间试验，研究了锌肥施用对水稻产量和籽粒锌含量的影响。结果表明，施用锌肥可以提高水稻产量，与不施锌肥处理相比，每hm2施用锌肥30 kg可使水稻增产8.8%，有效穗数和每穗实粒数分别增加10.2%和7.0%；施用锌肥还可以显著提高水稻成熟期各部位锌含量和锌积累量，与不施锌肥处理相比，每hm2施用锌肥30 kg后水稻籽粒锌含量和锌积累量分别增加36.2%和47.7%。

Abstract:

In order to investigate the application effects of Zn on yield and grain Zn concentration of rice, a field experiment was conducted. The results showed that the application of Zn fertilizer could increase rice yield. Compared with the control （S0）, the average yield of S30 treatment （30 kg/hm2 ZnSO4·7H2O） increased by 8.8%, the effective panicles and grains per spike increased by 10.2% and 7.0%, respectively. In addition, Zn fertilizer also significantly increased Zn content and Zn accumulation in individual rice organ. Compared with the S0 treatment, the Zn content and Zn accumulation of S30 treatment increased by 36.2% and 47.7%.

Key words: Zinc fertilizer, rice, yield, Zn content, Zn accumulation
