为了在蝴蝶兰规模化生产过程中实现定量化、精确化的施肥管理,以蝴蝶兰品种“内山姑娘”为材料,研究了不同氮、磷、钾配比施肥对蝴蝶兰营养生长及开花的影响。结果表明:在蝴蝶兰苗期适量的增加氮肥比例,能满足植株生长的营养需求,促进植株营养生长;不同氮、磷、钾配比施肥对花朵数的影响差异显著,对花朵直径、花梗直径、初花期的影响差异不显著;但花梗直径随着氮肥比例的增而呈增粗趋势;初花期随着氮肥比例的增加有提前的趋势。
In order to achieve quantitative and precise fertilization management in Phalaenopsis large-scale production, the Phalaenopsis species “Nei Shan Girl” was used to study the effects of nitrogen, phosphorus and potassium fertilization on vegetative growth and flowering of Phalaenopsis Impact. The results showed that increasing the proportion of nitrogenous fertilizer in phalaenopsis increased the nutritional requirements of plant growth and promoted the vegetative growth of the plants. The effects of nitrogen, phosphorus and potassium fertilization on the number of flowers had significant differences. The diameter of flower, , But no significant difference in initial flowering stage. However, the diameter of pedicel increased with increasing proportion of nitrogen fertilizer. The trend of early flowering increased with the increase of nitrogen fertilizer rate.
