Raising orchids can achieve the balance of root fungi and the flowering period will be long.

Orchids are fleshy roots and have no fibrous roots. Orchids symbiotic in fleshy roots absorb mineral nutrients from soil solution and provide them to orchids. On the other hand, the fleshy roots of orchids in turn provide necessary organic nutrients and water for orchids. They depend on each other and symbiosis with each other.

Therefore, the key to the cultivation of orchids is that the "root fungi" of orchids must be kept in a stable balance, so that the orchids can grow luxuriantly and bloom longer. So, how to maintain the balance of orchid "root fungi"? What florists need to do is to provide humus-rich soil for orchids and fertilize them as necessary.

Generally speaking, the rotten leaf soil rich in organic matter is used to grow orchids, and the soil is turned over every year or every other year. The soil contains enough nutrients for the growth and development of orchids, and liquid fertilizer can be used as topdressing without adding base fertilizer.

If the orchid pot has not changed soil for 3-4 years in a row, it is necessary to fertilize the orchid. On the one hand, appropriate base fertilizer can be added when preparing culture soil, such as fully fermented pig, cow, sheep dung, chicken manure or bean cake, oil crushed powder, broken cow horn powder, bone powder, plant ash and so on. But the amount should be appropriate, not too much.

On the other hand, a certain amount of topdressing can be added at the stage of growth and development, and the special organic liquid fertilizer for orchids can be used to dilute it 500 times. When applying it, it should be directly applied to the root of the orchid plant without splashing on the leaves of the orchid. Most of the nutrient solution is made of nitrogen, phosphorus, potassium and some trace elements, so it is necessary to master the concentration ratio when using it.

In addition, flower friends can also according to the needs of orchid growth and development, can apply potassium dihydrogen phosphate and other fertilizers to supplement nitrogen, phosphorus, potassium and other elements, but to strictly control the concentration and times.

If the orchid is cultivated with substrates such as volcanic stone, ceramsite, broken brick, perlite and so on, base fertilizer and topdressing must be applied. Base fertilizer is mostly made of chicken manure combined with some mineral nutrients, such as the size of broad bean particles. It can be used as base fertilizer when the orchid is put on the pot, or it can be laid flat on the basin surface at a distance of 3 centimeters, and it can be used as topdressing by continuous watering and leaching.
