摘要
【目的】探索生产富硒茶叶的施用肥料及最佳施用量,为大力发展富硒农业提供科学参考。【方法】试验以水灵1号和福云6号两个茶叶品种为材料,分别施用4种不同硒肥处理,对比茶叶增硒效果。【结果】在本试验处理条/kg),说明供试硒肥在推荐用量下均能满足富硒茶叶生产要求;供试4种肥料中,锌硒葆牌含硒叶面肥对茶叶增硒效果最好;处理1-3条件下,福云6号茶叶硒含量较水灵1号分别相对高出69. 7%、39. 6%、19. 9%。【结论】叶面增施硒肥是生产富硒茶叶有效措施,锌硒葆更适合用作富硒茶叶生产/667m2,兑水50kg叶面喷施;福云6号对外源硒肥更敏感,茶叶硒含量增加显著。
【Objective】In order to provide scientific reference for the development of selenium-enriched agriculture,the application of fertilizer and the best amount of fertilizer for the production of selenium-enriched tea were explored.【Method】Under the experimental conditions,each tea sample can reach the standard of selenium enrichment(>0.25mg/kg),which indicates that the selenium fertilizer can meet the production requirements of selenium rich tea under the recommended dosage.Among the four fertilizers tested,the brand of Zincselenbao selenium leaf fertilizer had the best effect on increasing selenium in tea,and the selenium content of Fuyun No.6 tea were 69.7%,39.6%,19.9%higher than that of Shuiling No.1 respectively under the treatment of 1-3.【Conclusion】Adding selenium fertilizer on leaf surface is an effective measure to produce selenium-enriched tea.the brand of Zincselenbao is more suitable for producing selenium fertilizer in selenium-enriched tea.The recommended amount is 50g/667m2.Fuyun No.6 was more sensitive to exogenous selenium fertilizer,and the selenium content of tea increased significantly,so Fuyun No.6 was suitable for producing selenium-enriched tea.
