| 摘 要： | 以砂糖橘为试材，研究了5年生和9年生树幼果期（坐果期至果实膨大期）单果干重，果实氮、磷、钾含量和单果氮、磷、钾累积量的变化。结果表明，5年生树幼果期单果干重显著大于9年生树；两种树龄果实氮、磷含量均随着果实的生长发育明显降低，而钾含量则先降低再升至恒定水平；单果氮、磷、钾累积量均随着果实的生长而迅速增加，5年生树钾累积量显著大于9年生树。

| Abstract: | Variation of single fruit dry weight, N, P, K contents and their single fruit accumulation of young fruits in fruit-set and fruit enlargement periods between 5-year-old and 9-year-old Citrus reticulate were studied. The results showed that dry weight of every fruit in 5-year-old trees was heavier than that of 9-year-old ones. The contents of N and P decreased significantly with fruit development in the two tested trees. However, the content of K decreased firstly, and then it increased and kept at a stable ... |
