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.
The results showed that the average content of N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu and B in citrus leaves of 7 high orchard orchards in Kaixian was the best. 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, (40.22 ± 0.37) mg / kg.Correlation analysis showed that among the above 11 elements There was a certain correlation between P and S, B were significant and very significant positive correlation, and Mn, Zn showed a significant negative correlation; most of the nutrients in leaves and fruit quality soluble solids negatively correlated with the Vc Was positively correlated.
