主要研究了喷施不同浓度硒肥对富士苹果硒含量、可溶性固形物、单果重及果实硬度的影响。结果表明:苹果果实硒含量随着喷施硒肥浓度的升高而增加,喷施硒肥可提高苹果果实单果重和可溶性固形物,对果实硬度无很大影响。此外,配套研究了富硒苹果绿色安全生产技术,经检测所生产的苹果绿色安全,无农药残留、重金属等残留。
The effects of different concentrations of selenium fertilizer on the selenium content, soluble solids, fruit weight and fruit firmness of Fuji apple were studied. The results showed that the content of selenium in apple fruit increased with the increase of selenium fertilizer concentration. Spraying selenium fertilizer could increase fruit weight and soluble solid content of apple fruit and had no significant effect on fruit firmness. In addition, supporting the study of the green-safe apple-rich production technology, the green apple production by testing security, no pesticide residues, heavy metals and other residues.
