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。
採用葉麵噴施、根施及根葉併施方式對獼猴桃植株進行富硒處理。結果錶明:3種施肥方式對于提高獼猴桃果實硒含量效果的順序為葉麵噴肥>根葉併施>根施,以葉麵噴施0.5 kg硒肥最優,果實硒含量增加瞭103.5%;提高果實維生素C(Vc)含量的效果順序為根施>根葉併施>葉麵噴肥,根施0.5 kg硒肥最為顯著,果實Vc含量增加瞭23.0%,而葉麵噴肥後果實Vc含量下降;提高果實可溶性固形物含量的效果順序為葉麵噴肥>根葉併施>根施,以葉麵噴施0.5 kg硒肥最優,果實可溶性固形物含量提高瞭37.2%。結閤獼猴桃果實硒含量、營養品質、果樹長勢以及果園管理成本等因素,建議選用果樹綻葉期根施硒肥0.5 kg·株-1作為富硒獼猴桃果園的施肥技術。

The effects of different fertilization methods on selenium content and nutrition quality of kiwifruits were employed for selenium for-tification. The fertilization methods were root fertilization, foliar fertilization and combined fertilization on their corresponding fertilizing peri-ods. The results demonstrated that selenium content of these three experimental groups was in the order of foliar fertilization>combined fertil-ization>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 fertil-ization>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 selenium fortification technology.
