| 中文摘要: |
| 采用叶面喷施、根施及根叶并施方式对猕猴桃植株进行富硒处理。结果表明:3种施肥方式对于提高猕猴桃果实硒含量效果的顺序为叶面喷肥>根叶并施>根施,以叶面喷施0.5 kg硒肥最优,果实硒含量增加了103.5%;提高果实维生素C(Vc)含量的效果顺序为根施>根叶并施>叶面喷肥,根施0.5 kg硒肥最为显著,果实Vc含量增加了23.0%,而叶面喷肥后果实Vc含量下降;提高果实可溶性固形物含量的效果顺序为叶面喷肥>根叶并施>根施,以叶面喷施0.5 kg硒肥最优,果实可溶性固形物含量提高了37.2%。结合猕猴桃果实硒含量、营养品质、果树长势以及果园管理成本等因素,建议选用果树绽叶期根施硒肥0.5 kg·株-1作为富硒猕猴桃果园的施肥技术。 |
| 英文摘要: |
| The effects of different fertilization methods on selenium content and nutrition quality of kiwifruits were employed for selenium fortification. The fertilization methods were root fertilization, foliar fertilization and combined fertilization on their corresponding fertilizing periods. The results demonstrated that selenium content of these three experimental groups was in the order of foliar fertilization>combined fertilization>root fertilization. Foliar fertilization with the dose of 0.5 kg was optimal, whose selenium content of kiwifruits increased by 103.5%. The vitamin C content of these three experimental groups was in the order of root fertilization>combined fertilization>foliar fertilization. Root fertilization with the dose of 0.5 kg was optimal, whose vitamin C content increased by 23%. However, the vitamin C content decreased as a result of foliar fertilization. The soluble solid content of these three experimental groups was in the order of foliar fertilization>combined fertilization>root fertilization. Foliar fertilization with the dose of 0.5 kg was optimal, whose the soluble solid content increased by 37.2%. Taking selenium content, nutrition quality, growth of plants and management costs of orchard into account, root fertilization at blossoming leaf stage with the dose of 0.5 kg selenium fertilizers was choosed as the optimal seleniumfortification technology. |
