树体的营养状况是果树获得早果、优质、丰产的关键,施肥是改善树体营养状况的有效途径。由于生产上很难凭经验对树体的营养状况做出准确的判断,致使长期以来果树施肥技术相对薄弱,盲目施肥、传统的经验施肥和偏重氮肥施入的不妥现象仍普遍存在,此为当今障碍果品质量提高的主要因素。利用营养诊断技术指导果树平衡施肥,是当前国内外将现代科研成果直接用于果树栽培管理,并取得显著成效的技术。多年来的研究及实践证明,它对提高果
The nutritional status of the tree is the key to obtain early fruit, good quality and high yield of fruit trees. Fertilization is an effective way to improve the nutritional status of tree. Due to the fact that it is difficult to make accurate judgment on the nutritional status of the tree by experience, the fertilization technology of fruit trees has been relatively weak for a long time. The blind application of fertilizers, the traditional experience of fertilization and the preference of nitrogen fertilization are still widespread Today’s barriers to improving the quality of fruit are the main factors. The use of nutritional diagnostic techniques to guide the balanced fertilization of fruit trees is a technology that directly applies the achievements of modern scientific research to the cultivation and management of fruit trees at home and abroad and has achieved remarkable results. Years of research and practice have proved that it is effective in improving fruit
