对深圳市4个典型丰产园糯米糍荔枝叶片7种矿质养分(氮、磷、钾、钙、镁、锌和硼)含量的统计分析表明:采样地点和生育时期均对叶片营养元素含量有显著的影响。四个关键生育时期(末次秋梢老熟期、花芽形态分化期、谢花期和果实成熟期)的单株样与混合(多株)样的供试矿质养分含量之间大部分没有显著差异。本研究根据丰产园糯米糍荔枝叶片混合样的分析结果提出了7种矿质养分的充足含量范围。
The statistical analysis of the contents of seven kinds of mineral nutrients (nitrogen, phosphorus, potassium, calcium, magnesium, zinc and boron) in the leaves of 4 typical high yielding sweet pots in Shenzhen showed that both the sampling sites and the growth stages had significant effects on the nutrient elements Impact. There was no significant difference between the single mineral samples and the mixed mineral samples for the four key growth stages (the last ripening stage of autumn shoots, the flower bud differentiation stage, the flowering stage and the fruit ripening stage). Based on the analysis results of the mixed samples of litchi leaves from the high yielding garden, this study proposed an adequate content range of seven kinds of mineral nutrients.
