【摘要】 以三种不同比例缓释固体肥与三种液体肥组合为苹果花卡特兰施肥,分析不同施肥处理对苹果花卡特兰生长与开花的影响,并对开花植株商品化性状进行评分,探讨营养配方对苹果花卡特兰商品化栽培的影响。结果表明,含N量较高的肥料有利于苹果花卡特兰叶片与假球茎生长,而P、K比例较高的肥料有利于假球茎发育和开花。苗期可使用含N量较高的肥料促进营养生长及抽生假球茎,成株期则施P、K比例较高的肥料促进假鳞茎成熟与花芽分化,使苹果花卡特兰多抽花枝多开花,增加观赏性状,提高苹果花卡特兰商品价值。更多还原

【Abstract】 The effects of different fertilizers on growth and flowering of potted Caularthron were carried out to discuss the optimum nutrition formulation for commercial cultivation of potted Caularthron. The results showed that high nitrogen fertilizer promoted vegetative growth, appropriate high proportion of phosphorus and potassium were useful for development of pseudobulbs and flower bud differentiation. It was suggested that using high nitrogen fertilizer in seedling stage and using high phosphorus and potassium fertilizer in adult stage were contributed to commercial cultivation of potted Caularthron.更多还原
