施肥对老芒麦种子活力——耐贮性的影响

Effects of Fertilizer Applications on Seed Storability of Elymus Sibiricus

在老芒麦种子生产田进行N、P、K肥单施、混施和喷施微量元素后,对其生产当年和贮藏三年后的种子萌发特性进行比较以及田间萌发试验的比较。结果表明:施N、P、K肥对收获当年和贮藏三年后的种子萌发力无显著影响;喷施微量元素对贮藏三年后的种子的萌发力有一定作用,提高了老芒麦种子的耐贮性,其中Mo对种子耐贮性有显著影响。

The effects of fertilizer applications of N,P,K, separately or in combination, and trace elements B,Mn,Zn,Mo on seed quality of ElYmus sibiricus were investigated. The seed germination capacity and storability were assessed in the harvesting year and after three years storage. The results showed that ap- plying N,P,K fertilizers,separately or in combination, had no obvious effects on seed germinability. Spraying trace elements had positive effects on promoting seed germinability for seeds three years storage.
