How do orchids fertilize?

Orchids are beautiful, but they are difficult to raise, especially reasonable fertilization. Briefly talk about the problem of orchid fertilization and share it with everyone!

1. What fertilizer is the most suitable for orchids?

Speaking of orchids, they are wild in Shan Ye, and the rotten leaves in Shan Ye are their roots. Therefore, if orchids want to thrive and bloom beautifully, the most inseparable fertilizer is decomposed organic matter, such as decomposed pine needle soil, decomposed sheep dung eggs, decomposed cake fertilizer and so on.

Using these fertilizers, the fertilizer effect is mild and lasting, and the most important thing is to facilitate the absorption of orchids, which is also conducive to the growth and flowering of orchids. The practice of orchid friends proves that orchids with mature organic matter have lush leaves, brighter colors and stronger fragrance when sprouting, and are less prone to fertilizer damage and root rot.

Therefore, when cultivating orchids, people often pay attention to the utilization of humus organic matter, such as adding some decomposed pine needle soil to hard planting materials, which can not only make the planting materials soft and hard, but also prevent the orchid roots from hanging and producing empty roots. The most important thing is that these organic substances are beneficial to the rooting and growth of orchids. In addition to mixing decomposed organic matter into plant materials, of course, we should also pay attention to using some organic fertilizer as base fertilizer, but don't let the roots of orchids directly touch the roots. Rational utilization of organic matter does not require fertilization even in the growth period.

Second, what fertilizer does the orchid need? Can I use urea?

Of course, in the growth of orchids, in order to meet the needs of growth and flower bud differentiation and flowering, we should pay attention to the use of some chemical fertilizers. There are many kinds of chemical fertilizers, including quick-acting nitrogen fertilizer urea, ternary compound fertilizer and, of course, some slow-release special fertilizers. I personally used these fertilizers. Let me briefly talk about my views on these fertilizers.

Let's talk about urea first. Urea has a quick fertilizer effect and is only suitable for promoting new buds in spring. It can quickly make orchids flourish, rejuvenate and sprout. However, because of its quick fertilizer effect, it is generally skillful to use. First of all, the dosage should not be too large, otherwise the succulent roots of orchids can not be absorbed, and it is very easy to cause fertilizer damage and root burning or rotten. And try not to use it at a slightly higher temperature. Dissolving and evaporating at high temperature will cause leaf burning.

Although the use of nitrogen fertilizer is quick-acting, it is easy to cause fertilizer damage and reduce the resistance of orchids. Generally, inexperienced flower friends do not recommend using urea in the roots. The best way to use urea is to spray it with solution, which can make the leaves flourish and is not easy to produce fertilizer damage. The concentration of the solution is about three thousandths.

Third, can orchids use compound fertilizer? How to use it?

Orchids should take root and grow leaves in the growth process to promote flower bud differentiation, which is the role of phosphorus and potassium fertilizer in compound fertilizer, so compound fertilizer can be used for orchid fertilization, especially slow-release compound fertilizer, which is more suitable.

First of all, Cymbidium hybridum plants are tall and have long leaves. Compound fertilizer should be used reasonably in the growth period, which can supplement phosphorus and potassium, so that the roots grow strong and the leaves are tall and strong, otherwise the leaves will not show the beauty and elegance of Cymbidium hybridum.

And orchids will enter the flower bud differentiation stage in early summer or summer. For example, Cymbidium goeringii will enter the flower bud differentiation stage in May and June, and Cymbidium hybridum will enter the flower bud differentiation stage in July and August. At this time, if they want the flower buds to differentiate smoothly and bloom brilliantly in the coming year, they must use compound fertilizer, which can not only promote the growth, but also promote the flower buds differentiation of orchids.

While using decomposed organic fertilizer, Chunlan can mix more than a dozen compound fertilizers in May and June, and it is best to use slow-release fertilizers. When the temperature is not very high in June, Cymbidium hybridum can use compound fertilizer. It is best to use it at night, and water it once the next morning, which is beneficial to absorption and can wash away too thick fertilizer, which is not easy to cause fertilizer damage; If it is a slow-release compound fertilizer, there is no need to pour back the soul water, because it is slow in fertilizer efficiency and will not cause fertilizer damage.

Furthermore, in autumn, in order to promote the growth of flower buds, expand flower buds as soon as possible and enhance the cold resistance of plants, some decomposed organic fertilizers can be mixed with some compound fertilizers to achieve the goal.

4. What are the skills of using orchid foliar fertilizer?

As mentioned above, urea can be sprayed as a solution to supplement the consumed nitrogen, and foliar fertilizers such as potassium dihydrogen phosphate can also be sprayed to supplement phosphorus and potassium. It can be said that the role of potassium dihydrogen phosphate is also very important. Let's briefly talk about the use of potassium dihydrogen phosphate in orchids.

Usually, if the leaves of orchids are lush, potassium dihydrogen phosphate can be used to enhance the photosynthesis of orchids, which will make the leaves more beautiful. In addition, the use of potassium dihydrogen phosphate can also be used to promote flowers. In the flower bud differentiation stage, potassium dihydrogen phosphate can be used once every half month, but not too frequently, usually two or three times. For example, Chunlan has it in May and June, and Cymbidium hybridum has it in July and August. Potassium dihydrogen phosphate can be used even at flowering stage. As long as the buds are wrapped in plastic bags, there will be no fat damage. Moreover, after using potassium dihydrogen phosphate, the color will be obviously brighter and the flowering time will be appropriately extended.

However, attention should be paid to time and temperature when using potassium dihydrogen phosphate. Generally, when potassium dihydrogen phosphate is used, it is necessary to get up early and spray it evenly before 10 or after 4 pm, giving consideration to both sides of the leaf surface. Moreover, the temperature in winter should be above 12 degrees, otherwise it will be difficult to absorb. (It can also be mixed with insecticidal and bactericidal drugs. )

Verb (abbreviation of verb) abstract

Orchid fertilization, the use of fertilizer is roughly so much. Of course, in order to achieve better goals, you can also use some orchid fertilizer. After all, orchids are born of a bacterium. If orchids are used reasonably, the new seedlings will speed up the service, and the old seedlings will grow more vigorously and grow more new buds. You can try.

Regarding the fertilization of orchids, it should be emphasized that some remedies, such as eggs and gutter oil, should not be used as much as possible. These things are irresponsible self-media people. In order to attract people's attention, if they are used, the soil will become sticky, attract some pests and even kill orchids. For some reason, propagandists have become so-called experts, and some people just like them, which is a bit puzzling!
