Orchid fertilizers, especially organic fertilizers, of course, are basically chemical fertilizers now. The common ones are compound fertilizers, of course, slow-release fertilizers, foliar fertilizers, and water-soluble fertilizers that are now sought after.

Nitrogen fertilizer is mainly for leaf growth and long skeleton. Phosphorus fertilizer is mainly related to flowering, while potassium fertilizer is a quality element, mainly to improve flowering quality and promote root buds. At this point, we basically know the principle of fertilization for orchids.

Orchid is mainly based on nitrogen fertilizer during the growth period. As long as it is beneficial to the vigorous leaves and thick branches, it is a long skeleton. In the flower bud differentiation period of orchids, phosphorus and potassium fertilizer are mainly used to promote the differentiation of flower buds and facilitate the extraction of flower buds. , To ensure the fullness of the flower buds and the number of flower buds, and after the flowers are blooming, the main nutrient fertilizer is mainly used to ensure the rapid recovery of the vitality consumed by the flowering.

There are many varieties of orchids, including Chunlan, Cymbidium, Molan, Coldlan, and Jianlan that can bloom in four seasons. Let’s talk about Chunlan. After the spring orchid is blooming, timely add nitrogen, phosphorus and potassium to restore its vitality. Of course, apply fertilizer. Don't be too single, you can supplement some trace elements appropriately.

The flower bud differentiation period of Chunlan is very long. It can last from July in the first year to bloom in the second year. According to the statement just now, after blooming to June, it is mainly nitrogen fertilizer, from July to the first year. In the second year, the arrow is mainly based on phosphorus and potassium fertilizer.

The last thing I want to say is that organic fertilizer is recommended for orchid fertilization, supplemented by chemical fertilizers, and more water-soluble fertilizers are used for fertilization. It is recommended to make up organic fertilizer once before winter, which can be sheep manure. Organic fertilizer is good for smoothness. After the dormant low temperature vernalization period, regular fertilization in the later period, mainly by watering and fertilization, and at the same time, proper spraying of foliar fertilizer can be used to topdress.
