农用稀土是以镧、铈、镨、钕为主的混合物,含R_2O_3 38%,无色无味易溶于水.我国对农用稀土的研究在国际上已处于领先地位,已成功地应用于小麦、水稻等十几种农作物上,对提高作物产量,改善品质起到了显著作用.辽宁省果树研究所在国光苹果树上应用稀土的研究已取得很大成绩,肯定了稀土在苹果树上应用的前景.在此基础上,我们把农用稀土和微量元素硼结合起来,应用到红星苹果树上,对树体发育、提高产量和改善果实
Agricultural rare earth is a mixture of lanthanum, cerium, praseodymium and neodymium, containing 38% of R 2 O 3, colorless and tasteless soluble in water.Research on agricultural rare earth in China has been a leader in the world and has been successfully applied to wheat, Rice and other crops on a dozen, to improve crop yield, improve quality played a significant role.Luo Ning Institute of fruit trees in Guoguang apple tree research has made great achievements, affirmed the prospects for the application of rare earth apple trees On this basis, we combine agricultural rare earth with trace element boron to apply it to Red Star apple tree, which is good for tree development, yield improvement and fruit improvement
