阳春砂仁叶片氮、磷、钾养分含量的变化规律,是按不同生理阶段对营养的要求,选择本区适生、旱生和湿生三种不同类型的种植园,以及施肥与不施肥的,分别于花芽分化期、花穗发育期、开花座果期、结果期和营养生长期采集叶样,用常规法分析氮、磷、钾养分含量的变化规律,为合理施肥提供依据。 The changes of nitrogen, phosphorus and potassium content in leaves of Amomum villosum were determined according to the requirements of nutrition in different physiological stages. Three different types of plantations, including adaptive, xerophyte and wetland, were selected, and the fertilization and non-fertilization The leaf samples were collected at the flower bud differentiation stage, the flower development stage, the flowering stage, the fruiting stage and the vegetative growth stage. The regularity was used to analyze the variation of nutrient contents of nitrogen, phosphorus and potassium, which provided the basis for rational fertilization.
