营养诊断作为农业生产现代化的技术之一从出现发展到现在已经给合理的营养管理带来极大的方便,为农业的高产、稳产提供了有力保证。但该技术进入林业生产领域却只是近二十年来的事情。目前林木的营养研究多停留在肥料试验和对林木体内养分动态变化规律的探讨上。营养诊断的新技术—综合诊断施肥法(Diagnosis andRecomendation Integrated System,DRIS)在林业生产上尚无成功的尝试。
As one of the agricultural modernization technologies, nutrition diagnosis has brought great convenience to reasonable nutrition management since its emergence and development, which has provided a powerful guarantee for the high yield and stable production of agriculture. But the technology into the field of forestry production is only the last two decades. At present, most of the nutrition research in the forest stays in the fertilizer experiment and discusses the dynamic changes of nutrients in the forest. The new technology of nutrition diagnosis - Diagnosis and Rehabilitation Integrated System (DRIS) has not been successful in forestry production.
