摘要
本文提出了福建省柑桔主栽品种芦柑叶片镁素营养的适量范围为0.27～0.39%.叶片分析结果表明,我省山地柑桔园缺镁相当普遍,分析叶样中有41.67～57.14%低于适量范围.对缺镁柑桔喷布0.5～1.0%硫酸镁溶液,可显著提高叶片含镁量,对矫治缺镁症是有效的.
It is suggested in present paper that the optimum value of leaf Mg element of cultivar C.reticulata in Fujian Province ranges from 0.27% to 0.39%.The results of leaf nutrient analysis showed that Mg deficiency in citrus leaf existed in many Fujian provincial orchards,about 41.67-57.14% of all leaf samples tested.Spraying 0.5-1.0% MgSO_4 solution can increase singnicantly the Mg content in citrus leaves,and it is can be used as a prastice for control Mg deficiency in citrus leaves.
