通过盆栽与小区试验，研究了稀土元素作玉米种肥对提高作物抗旱性能的影响。经作物苗期生长盛期对耕层土壤水分，水分生理指标及相关性的测定，在成熟期测产与方差分析等表明：１ｋｇ玉米种子用３ｇ稀土元素拌种肥能提高作物抗旱性能及主要生理功能，与对照处理比较，增产１６．７７％。
The effects of rare earth elements as maize fertilizer on the drought resistance of crops were studied by pot and plot experiments. The determination of topsoil moisture, water physiological index and correlation at the seedling stage of crop growth and yield and variance analysis at maturity showed that the dressing with 3g rare earth elements in 1kg maize seeds could improve the drought resistance of crops and the main Physiological function, compared with the control treatment, an increase of 16.77%.
