作者采用了3~2因子随机排列试验,分期采摘老叶进行测定,目的在于研究柑桔培养中钾和镁离子间的相互影响。本报告是根据1967年叶样分析的结果讨论如下: (1)施钾、镁肥对柑桔叶的营养成分产生了全面影响。如叶的含钾量增加,导致叶的氮、钙和镁成分显著地降低。反之,叶的含镁量增加,叶的含钾量也同样减少。镁对氮的吸收有辅助作用,因此,通过施用镁肥而使叶的含氮量增加。镁肥对柑桔叶的含锰量也有明显的辅助作用;但钾对叶的含锰量不发生什么影响。钾对叶的含钙量也不表
The authors used a 3 to 2 factor randomized test, staged picking of old leaves for determination, the purpose is to study the interaction between potassium and magnesium ions in citrus culture. This report is based on the results of the leaf-like analysis of 1967 as follows: (1) Potassium and magnesium fertilizers have an overall impact on the nutritional content of citrus leaves. As the leaf potassium content increased, leading to leaf nitrogen, calcium and magnesium components significantly reduced. Conversely, the increase in leaf magnesium content, leaf potassium content also reduced. Magnesium has an assisting effect on the absorption of nitrogen, so the nitrogen content of leaves is increased by the application of magnesium fertilizer. Magnesium fertilizer on citrus leaf manganese content also has a significant supporting role; but leaf manganese content does not have any effect. Calcium on the leaves of calcium is not taboo
