叶分析是诊断树体营养状态的一种可靠方法,已成为实现果树生产和科研现代化的重要手段。许多国家采用原子吸收光谱测定树体营养元素状况,使之数量化,从营养元素相互比例和平衡关系来全面衡量和协调树体营养。应用于生产使施肥合理化、指标化。 Leaf analysis is a reliable method to diagnose the nutritional status of trees and has become an important means to realize fruit tree production and scientific research modernization. Many countries use Atomic Absorption Spectrometry to determine and quantify nutrient elements in the tree and to comprehensively measure and coordinate tree nutrition in terms of the relative proportions and balance of nutrients. Applied to production to rationalize fertilizer, index.
