本文主要阐述稀土元素与锌在单独作玉米种肥的盆栽试验基础上,选出合适施用量,组成了稀土元素与锌不同用量的拌种处理,通过盆栽、小区试验对玉米主要生育期、生理功能、病虫危害、产量、种子品质、小区产量及方差分析等调查测定结果表明:每1kg玉米种子用2g硝酸混合稀土加入4g硫酸锌拌种,明显的优于对照及本试验五个处理。 This paper mainly elaborates the rare earth elements and zinc on the basis of the pot experiment of corn seed fertilizer alone, selects the suitable application amount, composing the seed dressing treatment with different amount of rare earth elements and zinc, The results of investigation and determination showed that the addition of 4g of zinc sulfate per 1kg of corn seed with 2g nitric acid mixed rare earth was obviously better than the control and the five treatments of this experiment.
