Preliminary Study on Nutritional Diagnosis of Jinggang Honey Pomelo Leaves
摘要
Abstract
The 97 representative grapefruit orchards of Jinggang honey pomelo were taken as the research object,and the contents of the nitrogen(N),phosphorus(P),potassium(K),calcium(Ca),magnesium(Mg),zinc(Zn),iron(Fe),manganese(Mn),Po and sulfur(S)elements in the leaves of Jinggang honey pomelo were measured.The diagnosis and recommendation integrate system(DRIS)was used to study the nutritional status of leaves.The results showed that according to the content range of mineral nutrient elements in the leaves of high-quality gardens,the appropriate values of N,P,K,Ca and Mg in Jinggang honey pomelo leaves were 23.15～25.86,1.89～2.56,12.06～15.24,40.65～61.45 and 1.85～2.00 g/kg,respectively.The appropriate values of Zn,Fe,Mn,Po and S were 20.13～32.30,124.04～178.98,88.87～147.56,86.39～143.25 and 1.19～1.59 mg/kg,respectively.The overall nutrient requirement order of orchards in Ji'an area was Mn＞Po＞Zn＞Fe＞Ca＞Mg＞N＞S＞P＞K.Jinggang honey pomelo orchard is relatively short of trace elements,especially in the low quality pomelo orchard,so regional specific fertilization management strategy can be adopted in the orchard according to the proposed nutritional diagnostic criteria.关键词
