摘要：氮是植物生长必需的营养元素。但氮肥的大量施用对生态环境、人类健康

Abstract: Nitrogen is an essential nutrient element for plant growth. However, the large-scale application of nitrogen fertilizer will have a negative impact on the ecological environment, human health and the maintenance of excellent germplasm resources. The strategy to solve this problem is to develop crops that use nitrogen efficiently and achieve higher seeds while reducing nitrogen input. Yield. This review mainly summarizes the important role of amino acid nitrogen on plants from the aspects of organic nitrogen absorption, transportation and utilization, and the physiological metabolism of amino acid transporter protein on plant yield, indicating that amino acid transporter protein also improves crop productivity and nitrogen use efficiency. One of the effective goals. <br>Keywords: amino acid; organic nitrogen; nitrogen

Abstract: Nitrogen is an essential nutrient for plant growth. However, the large-term application of nitrogen fertilizer will have a negative impact on the ecological environment, human health and the conservation of good seed resources, the strategy to solve this problem is to develop nitrogen efficient use of crops, in the case of reducing nitrogen input to achieve higher seed yield. This review mainly briefly describes the important role of amino acid nitrogen in plants and the physiological metabolism of amino acid transport protein participation on plant yield, and shows that amino acid transport protein is also one of the effective targets to improve crop productivity and nitrogen utilization efficiency.<br>Keywords: amino acids; organic nitrogen; nitrogen

摘要：氮是植物生长必需的营养元素。但氮肥的大量施用对生态环境、人类健康和优良种质资源的保持都会产生负面影响，解决这一问题的策略是开发氮素高效利用的作物，在减少氮输入的情况下实现较高的种子产量。该综述主要从有机氮的吸收转运和利用方面简述了氨基酸态氮对植株的重要作用以及氨基酸转运蛋白参与的生理代谢对植株产量的影响，表明氨基酸转运蛋白也是提高作物生产力和氮利用效率的有效目标之一。关键词：氨基酸；有机氮；氮<br>
