摘要
以开县7个丰产果园柑橘叶片为试材,对其进行营养元素的测定分析,结果表明:N、P、K、Ca、Mg、S、Fe、Mn、Zn、Cu和B元素含量的平均值分别为(3.0±0.06)%,(0.16±0.097)%,(0.8±0.34)%,(4.95±0.17)%,(0.29±0.19)%,(0.3±0.14)%,(124.5±0.18)mg/kg,(31.83±0.24)mg/kg,(11.77±0.15)mg/kg,(8.11±0.34)mg/kg,(40.22±0.37)mg/kg.相关性分析表明:以上11种元素之间存在一定相关性,其中P与S、B分别呈显著和极显著正相关,与Mn、Zn呈极显著负相关;叶片中大多数营养成分与果实品质的可溶性固形物呈负相关,而与Vc呈正相关.
In order to understand the nutritional status of orange orchards in Kaixian country, leaf samples were taken in seven productive citrus orchards and N, P, K, Ca, Mg, Fe, Mn, Cu, Zn and B in them were analyzed. The results showed that the average levels of N, P, K, Ca, Mg, Fe, Mn, Cu, Zn and B were （3.0±0.06）%, （0.16±0.097）%, （0.8±0.34）%, （4.95±0.17）%, （0.29±0.19）%, （0.3±0.14）%, （124.5±0.18） mg/kg, （31.83±0. 24） mg/kg, （11.77±0.15） mg/kg, （8.11±0.34） mg/kg and （40. 22±0.37） mg/kg, respectively. Correlation analysis indicated that there were relationships be- tween the levels of the 11 elements. P was in a highly significant positive correlation with S and B and in a highly significant negative correlation with Mn and Zn. Most of the nutritional elements were correlated negatively with TSS （total soluble solids） but positively with Vc.
