有益元素钛的植物营养学研究进展

Plant Nutrition of Beneficial Element Titanium: Research Progress

钛是作物生长的有益元素,对作物生长发育具有重要作用。笔者综述了土壤和植物中钛的含量、分布与影响因素、钛的生理生化功能及钛在农业上的应用等研究进展,并在此基础上提出加强土壤中钛的形态及生物有效性,钛施入土壤后的形态转化,作物有效性钛形态及测定方法,植物对钛的吸收、运输、转化等研究相关发展建议。

Titanium is a beneficial element and plays an important role in the growth and development of crops.In this paper,the content,distribution and influencing factors of titanium in soil and plants,the physiological and biochemical functions of titanium and its application in agriculture were summarized.The research on the form and bioavailability of titanium in soil,transformation of titanium after application to soil,the effective form and the method for determination of titanium,plant absorption,transportation and transformation of titanium should be strengthened.
