What fertilizer is good for orchids? What is the best fertilizer for orchids

It is best to use compound fertilizer, which is also rich in nutrients, including carbon soil, coconut peat soil, humus soil, etc., and you can also use plant ash as fertilizer, which is nutritious.

I think it's okay to use farmhouse manure. Because farmhouse fertilizer does not cause any harm to orchids, and it can also replenish nutrients in time.

Inorganic fertilizer, organic fertilizer, water-soluble fertilizer, and special fertilizer for orchid fertilization.

Inorganic fertilizers are mainly nitrogen fertilizers and potassium fertilizers, urea and potassium dihydrogen phosphate can be applied, and organic fertilizers are used as base fertilizers. Apply water-soluble fertilizer, mix water-soluble fertilizer with water, and then water to the roots of the orchid. Water-soluble fertilizer can promote the roots to fully absorb nutrients, and when raising orchids, you can use special slow-release fertilizer for orchids.

It is specially developed for orchids and can effectively promote the growth of orchid roots. Usually organic fertilizer (special orchid) refers to cake fertilizer, after all, although other organic fertilizers in rural areas have good fertility, they are obviously not suitable for raising orchids. At least the smell is unbearable, and the application of cake fertilizer on orchids has a very obvious effect on the growth of orchid seedlings.

The leaves are thick and green like a piece, straight and elegant.

Promote the effect

It also has a good effect on promoting the pregnancy buds and flowering of orchids. But the cake fertilizer is not harmless, the use must go through a long time of making, although there is a way to soak water and water the flowers, but the effect is not as good as the mixed planting material after the maturity. If there is no ripe cake fertilizer in the pot, there will be a phenomenon of fermentation again and rotten roots.

Moreover, unripe cake fertilizer can easily lead to orchid diseases (miscellaneous bacteria are more likely to breed).

Generally, the chemical fertilizer of the agricultural material store can be applied to the orchid (except for chlorine), and the fertilizer with different nitrogen, phosphorus and potassium content can be used according to the source group of the different stages of orchid growth. Generally, the content of nitrogen, phosphorus and potassium is 17% each, of which potassium is in the form of potassium sulfate. The effect of fissing and fertilizing in orchid pots is very fast, and the fertility can be clearly felt within 7 days, the leaves begin to turn green, and the growth rate of new seedlings is significantly accelerated.

Inorganic fertilizer: Inorganic fertilizer, that is, chemical fertilizer, can be applied appropriately during the growth stage of orchids. Chemical fertilizers are mainly nitrogen fertilizer and potassium fertilizer, urea and potassium dihydrogen phosphate can be applied, urea solution can be diluted with water 150-200 times, the roots of orchids are watered, and potassium dihydrogen phosphate is diluted 200 times with water and the leaves are sprayed.

Organic fertilizer: Orchid flowers are mainly applied to organic fertilizer for a long time, such as cake fertilizer, fish bones, orange stalks, fallen leaves, grass, human and animal manure, etc., which can also add enough nutrients to orchids, and the fertilizer effect is relatively moderate. Organic fertilizer is mainly used as a base fertilizer, which should be sterilized and insecticidal, fully fermented, and mixed into the soil when potting to ensure good nutrient supply.

It can also be used as top dressing, which can be used to dig a pit in the soil around the roots of the orchid, apply fertilizer to it, and cover the soil.

Water-soluble fertilizer: Orchids can also apply water-soluble fertilizer, mix water-soluble fertilizer with water, and then water to the roots of orchids, water-soluble fertilizer can promote the roots to fully absorb nutrients.

Special fertilizer: When raising orchids, you can use special slow-release fertilizer for orchids, which is specially developed for orchids and can effectively promote the growth of orchid roots.

Sterilization and disinfection: When using organic fertilizer, orchids can be sterilized and disinfected in advance, which needs to be fermented first, and then steamed at high temperature to kill germs and insect eggs.

Thin fertilizer and frequent application: When applying fertilizer to orchids, we must insist on thin fertilizer and frequent application.

Organic fertilizer is best for orchids, as detailed below:

Root fertilizer can be used bark blocks, leaves, peat, coconut shells, chaff, peanut shells and other organic matter, these organic matter needs to be fermented before use, it is best to cook at high temperature to kill germs and insect eggs, the ability of organic matter to absorb water after cooking will also be enhanced, and the speed of organic matter release will also become faster.

You can also directly use organic fertilizers such as cake fertilizer, cow dung, sheep manure, etc. It can also be used for chemical fertilizers such as urea on the surface of the planting material, long-term coated slow-release fertilizer, such as Aolu, Haokangduo, magic fertilizer, etc. The leaves can be diluted with organic fertilizer with water, or the leaves can be sprayed directly with chemical foliar fertilizers, such as potassium dihydrogen phosphate, Huabao, Xishuo, etc.

There are two types of orchid fertilization

There are two types of orchid fertilization methods, one is: root fertilization and the other is: foliar fertilization.

The roots and leaves of orchids can absorb and use fertilizer, foliar fertilization is a supplement to root fertilization, fertilizer effect is fast, immediate, can not be relied on or used for a long time, should be used in conjunction with root fertilization.

Root fertilization is divided into two situations: the one that is directly mixed with organic matter or organic fertilizer in the planting material is called "base fertilizer", and the one that is applied from the surface of the planting material is called "top dressing". The base fertilizer should not be too much, in order to avoid fertilizer heat injury to the roots or make the root bark black, top dressing is a supplement or adjustment of the insufficient fertilizer in the pot.
