山东省稀土农用研究历经２０余年。现已基本查清了５０个土属１２５６３．６万亩耕地土壤的可溶态稀土含量；明确了全省十余种作物、果树及蔬菜在不同生育期不同器官中的稀土含量、吸收波峰及分配比率；完成了１０６个试验区的大田试验，总结出稀土肥对各种作物的增产幅度、最佳施用方式及用量。稀土肥中硝酸根的作用及稀土元素对细胞活性影响的电镜观察，为稀土肥施用提供了依据。
Shandong Province rare earth agricultural research after more than 20 years. Has now basically cleared the 50 soil 125.646 million mu of cultivated soil soluble rare earth content; clear the province more than ten kinds of crops, fruit trees and vegetables at different growth stages of different organs of rare earth content, absorption peaks and Distribution ratio; completed field trials of 106 experimental areas, summed up the yield of rare earth fertilizer on a variety of crops, the best mode of application and dosage. The role of nitrate in rare earth fertilizers and the effect of rare earth elements on the cell activity by electron microscopy, provided the basis for the application of rare earth fertilizers.
