富硒肥对茶树的影响及新型硒肥研究进展

Research Progress of Influence of Selenium-Enriched Fertilizer on Tea Plant and New Selenium Fertilizer

茶硒是一种优质硒源,富硒茶生产对人体硒的摄入具有重要意义。通过施用硒肥提高茶叶硒含量是生产富硒茶的科学途径,新型硒肥的发展为优质富硒茶的生产提供了基础,但不同硒肥对茶树的影响机制不同。综述了硒对茶树的作用、影响茶叶硒含量的因素、硒肥施用现状等,同时探讨了缓控释硒肥、纳米硒肥、微生物硒肥、螯合硒肥4种新型富硒肥料在茶树上的应用进展,分析了新型硒肥的优势与不足,并指出了今后的发展方向,为富硒茶的生产及茶叶品质提升提供理论与技术依据。

The selenium in tea is a kind of high-quality source of selenium,the production of selenium-enriched tea is of great significance for human selenium intake.The application of selenium fertilizer is a scientific way to increase selenium content in tea,and the development of new type of selenium fertilizer provides the basis for the production of high-quality selenium-enriched tea,but different selenium fertilizers have diverse effects on tea.This paper given an overview of the effect of selenium on tea,the factors of affecting the selenium content of tea and the application status of selenium fertilizer and so on.At the same time,this paper systematically introduced the application progress of four new kinds of selenium-enriched fertilizers in tea which include controlled-release selenium fertilizer,nano-selenium fertilizer,microbial selenium fertilizer and chelated selenium fertilizer.In addition,according to the advantages and disadvantages of the current new type of selenium fertilizer,a theoretical basis for the production of selenium-enriched tea was provided and the direction for its further development was pointed out.
