| 为探究肥料中磷、氮、钾三要素的耦合对银杏可溶性糖含量的影响,在吕梁大道的银杏树生长
环境中,通过土壤调查和试验设计,选定土壤质量最佳的区域,将其挖回温室,选择相同生长状态的
5 a银杏实生苗,采用回归正交设计,调配不同含量的磷肥、氮肥、钾肥,并测量银杏叶中的可溶性糖含量。实验结果表明,磷肥与氮肥、磷肥与钾肥的联合施用对银杏还原性糖含量具有显著正向效应,而独立施用磷肥、氮肥、钾肥可溶性糖的影响较为有限;在土壤中添加磷肥40 kg/hm2、氮肥60
kg/hm2、钾肥80 kg/hm2的配比时,银杏可溶性糖含量最高,为11.56%,显示出显著的交互效应。综合而言,通过优化土壤中磷、氮、钾的比例,可有效提高银杏的可溶性糖含量,增强其成活率和抗

| 英文摘要: |
| To investigate the effects of the coupling of phosphorus (P), nitrogen (N), and potassium (K)
in fertilizers on the soluble sugar content in Ginkgo biloba, the soil survey and experimental design were
conducted in the growth environment of Ginkgo biloba along Lyuliang Avenue. The area with the best soil
quality was selected and transferred to a greenhouse. Five-year-old Ginkgo biloba seedlings with similar
growth status were chosen, and a regression orthogonal design was employed to formulate different levels
of P, N, and K fertilizers. The soluble sugar content in Ginkgo biloba leaves was measured. The experimental
results showed that the combined application of P and N, as well as P and K, had a significant
positive effect on the reducing sugar content in Ginkgo biloba, while the individual application of P, N,
or K had limited effects on the soluble sugar content. The highest soluble sugar content in Ginkgo biloba,reaching 11.56%, was observed when the soil was supplemented with 40 kg/hm2 of P, 60 kg/hm2 of N,
and 80 kg/hm2 of K, indicating a significant interaction effect. In conclusion, optimizing the ratio of P, N,
and K in the soil could effectively enhance the soluble sugar content in Ginkgo biloba, improve its survival
rate and stress resistance, and provide a scientific basis for the cultivation and growth of Ginkgo biloba. |
