摘要:

目前水稻籽粒锌含量普遍较低,叶面锌肥喷施技术效果显著,合理优化叶面喷施方案,实现增效降本,对该项技术的推广具有积极作用。本研究采用不同锌肥和施锌模式,在浙江绍兴开展田间试验,分别就锌肥种类、锌肥喷施时期、锌硅配施处理对水稻产量及籽粒锌含量的影响开展研究。结果表明,适量施用锌肥可以显著(p<0.05)增加水稻产量及籽粒锌含量,其中以螯合糖醇锌效果最好,其水稻产量和籽粒锌含量分别较对照增加8.2%和81.7%。此外,在水稻灌浆期前喷施1次、灌浆期喷施2次锌肥以及适当浓度的锌硅配施在一定程度上实现了水稻产量和籽粒锌含量增加的目的。

Abstract:

At present,the zinc content of rice grain is generally low,and the effect of foliar zinc fertilizer spraying technology is remarkable. Reasonable optimization of foliar spraying scheme and realization of efficiency enhancement and cost reduction have a positive effect on the promotion of this technology. In this study,different zinc fertilizers and zinc application modes were used to carry out field experiments in Shaoxing,Zhejiang Province. The effects of zinc fertilizer types,zinc fertilizer spraying period and zinc-silicon combined application on rice yield and grain zinc content were studied. The results showed that the appropriate application of zinc fertilizer could significantly(p<0.05)increase rice yield and grain zinc content,among which chelating sugar alcohol zinc had the best effect,increasing rice yield and grain zinc content by 8.2% and 81.7%,respectively,compared with the control group. Besides,spraying once before the filling stage of rice,spraying zinc fertilizer twice during the filling stage and appropriate concentration of zinc and silicon combined application achieved the purpose of increasing rice yield and grain zinc content to a certain extent.

Key words: foliar spraying, zinc fertilizer, spraying period, rice grain
