水稻喷施稀土复合微肥的效应

EFFECT OF SPRAYING WITH RARE EARTH COMPLEX MICROFERTILIZER ON RICE

试验表明，水稻喷施农用稀土溶液有明显的增产效果。采用四川大学研制的稀土复合微肥，比施在用硝酸稀土增产更为显著。水稻植株中稀土元素分布的研究显示，无论是否施用稀土，水稻植株各部位均有稀土元素存在。喷施稀土后，稻米中的稀土无显著差异。其它部位均有变化。

Experbonts showed that the rice plants sprayed with olution of agricultural applicable rare earth had obvious effects on the imcrease of the rice output. The efficacy of complex rare earth prepared in S. U. was better than that of agricultural applicable nitrate of rare earth. Tha analysis of distribution of rare earth elements in rice plant showed that the all parts of rice plant contained rare earth elements whether the rare earths were aprayed or not, except for rice grains. The contens of rare earths in all the other parts of the plant had changed after apraying with rare earths.
