Do you know what fertilizer is good for orchids?

Orchid fertilizer can be divided into three categories of organic fertilizer, inorganic fertilizer and biological fertilizer from the material, organic fertilizer is the product of organic material fermentation and decay, such as fermented and rotten leaves, branches, sheep manure, cow dung, etc., inorganic fertilizer is what we often call chemical fertilizer, commonly used in orchids are: urea, potassium dihydrogen phosphate, nitrogen, phosphorus and potassium ternary compound fertilizer; Microbial fertilizer is a product that causes crops to obtain specific fertilizer effects due to microbial life activities.

The most commonly used elements for the fertilizer required for orchids are: nitrogen, phosphate, and potassium. And then there's the secondary element:

Calcium, magnesium and sulfur fertilizers. There are also trace elements: boron fertilizer, zinc fertilizer, copper fertilizer, iron fertilizer, molybdenum fertilizer, etc., we mainly supplement nitrogen, phosphorus and potassium, which are the nutrients that orchids need and take away more, and others can be temporarily ignored.

Among orchids, we commonly use organic fertilizer and inorganic fertilizer, inorganic fertilizer commonly used urea and potassium dihydrogen phosphate to spray leaves and irrigate roots, urea belongs to nitrogen fertilizer, can promote the growth of orchid stems and leaves, so that the leaves are lush, the leaf color is dark green, improve the protein content, urea ** is not high, there are no special requirements for soil quality and pH value, many people like to use urea to fertilize orchids, potassium dihydrogen phosphate is a phosphate fertilizer, which can promote the differentiation of orchid buds, so that orchids bloom more and sprout more. Chemical fertilizers can only be used after high dilution, many people like to use efficient and safe slow-release fertilizer, slow-release fertilizer contains more nutrients, can meet the needs of orchids at all stages of fertilizer, put it on the pot surface and don't care, fertility will flow into the pot with each watering for orchid absorption, saving time and effort, commonly used are Ao green manure, good Kangduo and so on.

Orchid fertilization should be carried out in sunny weather, the temperature is better at 15-30 degrees of fertilization, fertilization time in spring and autumn, other seasons can not be applied, spring and autumn is the season for orchid germination and growth, suitable for fertilization, each season can be applied 2-3 times, each time the interval is about half a month.

Did you get it?

Organic fertilizer, chemical fertilizer, biological fertilizer. These fertilizers have a significant effect on the growth of orchids, making the leaves thick and green, and also resistant to pests and diseases.

I know, because I have orchids like this in my yard, I usually use some compound fertilizer.

It is best to use nitrogen and potassium fertilizers, which can promote the growth of plant rhizomes. Phosphate fertilizers can also be used, which can prolong the flowering period of orchids.

Orchids grow well and can't do without fertilizer. As long as people who love flowers, this is generally known, and the choice of fertilization is also very diverse, you can choose inorganic fertilizer, diluted and sprayed with a watering can, which can make the orchid leaves look better. You can also choose compound granular fertilizer, take out the appropriate amount of fertilizer and put it on top of the potting soil.

If you want the roots of orchids to grow strongly, you can use special slow-release fertilizer for orchids, but you can't apply too much fertilizer, which is easy to cause excess nutrients.

1. Inorganic fertilizer.

Inorganic fertilizer can be selected for orchid foliage, but inorganic fertilizer needs to be diluted before it can be used, and spraying it on the foliar surface can be used. But pay attention to the number of spraying, about 10 days or so to spray once, master the method so that the orchid leaves can be more green.

2. Compound granular fertilizer.

Orchid fertilization can also choose compound granular fertilizer, the best way is to evenly sprinkle the appropriate amount of fertilizer on the potting soil of the orchid pot, with the passage of time the compound granular fertilizer will dissolve into the soil, this fertilizer can allow the roots of the orchid to absorb nutrients, promote the better growth of orchids.

3. Special slow-release fertilizer for orchids.

If you want to promote the growth of roots, it is better to apply an appropriate amount of slow-release fertilizer for orchids. This fertilizer can allow the roots of the orchid to better absorb nutrients, but it should be noted that it should not be applied too much, an appropriate amount can be, if the amount is large, it is easy to burn the roots, so that the growth of the orchid has problems.

4. Nitrogen, phosphorus and potassium fertilizers.

Nitrogen, phosphorus and potassium fertilizers are very beneficial for the growth of orchids, and can be diluted and applied once every 15 days or so. When spraying with nitrogen, phosphorus and potassium fertilizers, be careful not to sprinkle the diluted fertilizer on the leaves, which is easy to cause damage to the leaves.

1. Inorganic fertilizer: Inorganic fertilizer can be applied appropriately during the growth stage of orchids, that is, chemical fertilizers. 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.

2. 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.

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

4. 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.

1. What fertilizer is used for orchids?

1. Special fertilizer: There are special fertilizers for orchids on the market. If you do not know how to prepare fertilizer, it is recommended to buy special fertilizer directly for orchid application. The special fertilizer for orchids is specially designed for orchids, which is in line with the growth habits of orchids, and is suitable for fertilizing orchids.

2. Homemade fertilizer: If you don't want to buy special fertilizer, you can also make your own fertilizer. Mash fruit skins, fish bones and other substances into a bottle, add some water, and let the water surface reach about three-quarters of the height of the bottle.

Then screw the cap and place it in a warm place to ferment. After about 2-3 months, the fermentation is complete and they can be used as fertilizer.

Second, how to apply blind fertilizer to orchids.

1. Growth period: the growing season of orchids in spring and summer. At this time, it is recommended to apply flower dressing fertilizer 1-2 times a month. When fertilizing, the fertilizer should be diluted with water before applying it to the plant, so as not to burn the root system of the plant with too concentrated fertilizer.

2. Summer: Plants will also grow in summer. However, because of the high temperature, it does not grow very quickly, so the frequency of fertilization should be reduced. Generally, fertilization every 2-3 months is fine. It is best to apply slow-release fertilizer.

3. Winter: In winter, the temperature is very low, orchids grow very slowly, need less nutrients, and do not need to fertilize. Wait for the temperature to rise in the spring of the next year, and then fertilize it.

Orchid flower fertilizerWhat are the commonly used flower fertilizers for orchids 1. Inorganic fertilizer. Orchids need to be used with caution, because the fertilizer contained in inorganic fertilizer is different, and the effect on orchids is not the same. Generally, the commonly used inorganic fertilizers mainly include urea and potassium dihydrogen phosphate, and it should be noted that when applying inorganic fertilizers to orchids, the fertilizer concentration should be lighter, otherwise it will cause certain damage to the orchid plant.

2. Organic fertilizer. Generally, it is made of fertilizer, and its raw materials mainly include soybean cakes, chicken feathers, river mussels, rapeseed cakes, fish belly sausages, etc. Use these raw materials to seal the bubble liquid, brew for one to two years, and then take out the clear solution and dilute it when fertilizing the orchid.

Because this kind of fertilizer contains nitrogen, phosphorus, and potassium, the fertilizer content is relatively complete, and it is still very good to raise orchids.

3. Fertilizers such as orchid fungus king, Xishuo, Zhiquan and promoting the root growth of cleaning pants sold in the flower market are also used by many orchid raisers, and they belong to high-efficiency synthetic flower fertilizers or biological bacterial fertilizers.

4. Orchid fertilization is usually supplemented with nitrogen, phosphorus and potassium These three elements, nitrogen fertilizer is generally urea, phosphorus and potassium fertilizer is generally potassium dihydrogen phosphate, spring and autumn are the seasons for orchid leaf growth, and nitrogen and potassium fertilizer are supplemented. What is the most suitable flower fertilizer for orchids 1. Shiitake mushroom soil: It is acidic and suitable for orchids.

The nutrients contained in it are relatively moderate, and the fertilizer effect time is long. And it can be used both as a fertilizer and as a substrate. Compared with other substrates, it has a looser texture, and has better drainage and air permeability.

2.Crust charcoal: This substance contains more potassium, and after application, it can make the soil more loose, and it can also increase the temperature of the soil appropriately.

It is inherently alkaline. However, after a month or two of sun exposure, it can be neutral and then used normally.

3. Bone char: It is mainly used as a phosphate fertilizer, because it is particularly rich in phosphorus. In addition, as a fertilizer, it works quickly and can last for a long time.

Organic fertilizer for orchid fertilization.

Usually I say organic fertilizer (special orchid) refers to cake dust buried fertilizer, after all, although the fertility of other organic fertilizers in the countryside is good, but it is obviously not suitable for raising orchids, at least the smell is unbearable. The application of cake fertilizer on orchids has a very obvious effect on the growth of orchid seedlings, and the leaves are thick and green, straight and elegant. It also has a good effect on promoting the pregnancy buds and flowering of orchids.

When preparing orchid planting material, you can consider adding some materials with its own fertility (I advocate humus) and mixing some biological fertilizer when planting. In the spring and autumn of each year, you can apply some mature organic fertilizer, which has a long-lasting effect. In the peak season of orchid growth (mainly spring and early summer), chemical fertilizers can be applied to promote the germination and pregnancy buds of orchid plants.

Orchid care tips

1. Suitable soil.

Orchids are mainly planted with decaying leaves and dead branches, pine bark and peanut shell-based micro-liquid wheel acid humus soil, which can be purchased directly in the market for orchid soil, or you can make it yourself, with rotten dead branches and leaves, ceramsite, perlite, etc., with some impurities-free garden soil, according to 2:1:1:

The ratio of 2 is mixed, and the soil is loose and breathable, which is very suitable for planting.

2. Appropriate lighting.

Orchids are shade-loving plants and avoid strong light, so they are generally placed in a cool and astigmatistic position. However, it still needs to receive sunlight for its growth, and generally receives scattered light after 5 o'clock in the evening. In addition to winter, orchids should be shaded, and in winter they can be used for astigmatism, but they should also control the time to avoid direct sunlight and sunburn the plants.

Proper light can promote the growth and opening of flowers, and a ventilated environment is conducive to the healthy growth of plants.

3. Management of fertilizer and water.

The control of water should be the most difficult to control in the cultivation of orchids. The vigorous growth period of orchids is summer, and the demand for water is slightly larger, so it should be watered once a day, and it can be watered twice a day according to soil conditions; In spring and autumn, water is basically once every 3 days, and you can also spray water around the orchid placement to ensure the humidity of the surrounding air.
