摘要
为探索全球红葡萄的需肥规律,实现平衡施肥,本研究通过田间采集植株样品和室内养分分析,初步探索氮、磷、钾三要素在全球红葡萄各器官中的分配和浓度变化及在各生育阶段植株氮、磷、钾含量的动态变化,得出萌芽及新梢生长期和果实膨大期是2个重要的全球红葡萄需肥时期,全球红葡萄对氮、磷、钾的吸收量为K2O>N>P2O5,对氮、磷、钾的吸收均是在果实膨大期达到最大。
To probe into the regularity of nutrient requirement of Red Global grape and realize balance fertilization of it, the distribution and concentration variety of N, P, K of every growth period in different organ were studied by random sampling and laboratory analysis. The resuhs showed that the budding and fruit expanding period was an important period in demand for fertilizer during the growth of Red Global grape, the amount of N, P, K absorbed is K2O 〉 N 〉 P2O5, the maximum amount of N, P, K absorbed is the most in fruit expanding period and related with the biggest growth capacity.
