摘要: 实行肥料科学配施与红壤培肥管理是山区草业发展的重要技术环节.我国南方红壤区土壤普遍存在着硼、钼、硒元素缺乏现象,合理施用钼、硼、硒微量元素肥料对豆科与禾本科牧草的植株生长以及提高产草量和种子产量有明显的促进作用.文中概述了我国红壤区土壤中钼、硼、硒元素的存在形态、化学特征、内在变化、可给性及含量状况,探讨了施用3种微量元素肥料对牧草生长过程有效养分吸收与累积的影响及其相应生理功能,综述了牧草植物缺乏钼、硼、硒元素的特征症状、诊断方法及其矫治措施.

Abstract: Reasonable fertilization and fertility improvement of red soils are the important measures to develop the forage industry in hilly regions of South China.This paper summarized the existing form,chemical feature,availability and content of molybdenum,boron and selenium in red soils of South China.The lack of these three microelements in red soils was in common,and their reasonable application could significantly improve the growth of forage grass and its yield.The authors discussed the effects of molybdenum,boron and selenium application on the uptake and accumulation of available nutrients by forage grass and relevant physiological functions,described the molybdenum,boron and selenium deficiency symptoms of forage grass,their diagnostic methods and correcting measures,and put forward some suggestions for deepening the study.

Key words: Red soil, Molybdenum, Boron, Selenium, Forage grass, Grass growth
