摘　　要：植物营养学是一门通过研究植物从环境中吸收营养元素、养分运输途径及植物自身构建有机体的学科,是与土壤、生物、资源、环境、生态及肥料等领域有关的一门交叉学科,任务是通过生物田间试验、生物模拟、化学实验分析、酶学诊断、核素技术及数理统计等方法,分析植物体自身的营养物质转化利用机制及其与外界环境之间的营养物质交换、能量传递及逆境适应等方面的具体过程。目的是通过研究植物体的营养物质吸收、运输和利用机制以及营养物质在植物体内的科学分配和能量转化的规律,并结合土壤理化性质、养分归还及植物遗传特性的调节或改良,达到明显改善土壤环境、提高作物产量和品质的目的。作为涉农类专业学生的必修核心课程,植物营养学与农业生产实践有着紧密的联系,在保障国家粮食安全、促进肥料健康发展、提高农产品品质及保护生态环境等方面有着重大意义。该文在总结我国高校植物营养学课程建设经验的基础上,结合西藏高校特有的教学环境和教学实践,归纳民族地区高校传统植物营养学课程教学中存在的不足,提出一些适合西藏高校植物营养学课程教学的建议,从而为培养下得去、懂技术、爱农业的高科技人才提供帮助。Plant nutrition is a subject that studies the absorption of nutrients from the environment,the ways of nutrient transport and the construction of organisms by plants themselves.It is a cross-discipline related to the fields of soil,biology,resources,environment,ecology and fertilizer.Its task is through biological field experiments,biological simulation,chemical experimental analysis,enzyme diagnosis,radionuclide technology and mathematical statistics.The mechanism of transformation and utilization of nutrients and the specific processes of nutrient exchange,energy transfer and stress adaptation between plants and the external environment were analyzed.Its purpose is to improve the soil environment and crop yield and quality by studying the mechanism of absorption,transport and utilization of nutrients and the law of scientific distribution and energy transformation of nutrients in plants,combined with soil physical and chemical properties,nutrient return and the regulation or improvement of plant genetic characteristics.As a compulsory core course for students majoring in agriculture,plant nutrition is closely related to agricultural production practice.It is of great significance in ensuring national food security,promoting the healthy development of fertilizers,improving the quality of agricultural products and protecting the ecological environment.Therefore,on the basis of summarizing the experience of the construction of plant nutrition courses in colleges and universities in China,andutilizing the unique teaching environment and teaching practice of Tibetan universities,this paper summarizes the shortcomings in the teaching of traditional plant nutrition courses in colleges and universities in ethnic minority areas.this paper puts forward some suggestions which are suitable for the teaching of plant nutrition courses in Tibetan colleges and universities,so as to provide help for the cultivation of high-tech talents who can go,understand technology and love agriculture.
