摘    要:通过对4个果园中产量高、中、低三个等级龙眼的土壤和植株养分分析,结合龙眼产量测定,探讨龙眼钙、镁营养元素的营养诊断指标。以交换性钙和交换性镁作土壤钙、镁营养元素诊断的诊断形态,以1月份时中上部老熟秋梢(结果母枝)第2位叶的全量钙、镁作为龙眼植株钙、镁营养元素的诊断形态,分别拟定出了土壤、植株钙和镁营养的诊断指标。

关 键 词:龙眼 钙 镁 营养诊断 施肥

Abstract:Based on the results of both soil, leaf nutrient analysis and the yields of longan fluid in different soil fertility status, the nutrition diagnosis of calcium and magnesium was investigated in this study.Using the soil exchangeable calcium and magnesium, and the total calcium and magnesium in 2th leaf order of the mature branch sprouted in Jan. as the diagnostic form, the calcium and magnesium nutrition diagnostic mark of the soil and plants were shown in this report.
Keywords:longan  calcium  magnesium  nutrition diagonsis
