研究表明 ,不同浓度稀土对红富士苹果果形指数、可溶性固形物含量及产量影响差异显著 ,对果实着色指数、平均单果重影响差异极显著 ;喷施稀土后 ,促进了树体对营养元素的吸收 ,叶绿素含量增加 ,其中以 12 0 0 mg/kg稀土最适宜 The results showed that the effects of different concentrations of rare earth on fruit shape index, soluble solids content and yield of red Fuji apples were significant, and the difference was significant between fruit color index and average fruit weight. After spraying rare earth, Absorption, chlorophyll content increased, of which 12 0 0 mg / kg rare earth most suitable
