近二十年来,营养诊断研究的迅速发展,使柑桔的产量和质量得到很大提高。Chapman的工作证明了用叶片的营养指标能有效地估测植株的营养状况,以指导桔园施肥和对缺素症的矫正。笔者于1983～1985年,在完成湖南省内一些桔园的营养与施肥调查的基础上,开展了用叶片分析结果指导桔园施肥的试验。在全省10个市(县)的园艺场取得了较好的效果。
In the past 20 years, the rapid development of nutrition diagnosis research has greatly improved the yield and quality of citrus fruits.
