How do you plant weak seedlings of orchids? What plant materials are used for orchids with weak seed

People who raise orchids generally encounter this problem, the same orchid species, other people's orchids are verdant and lush, the leaves are tall and strong, and the buds are continuous; Their own orchids are lonely, the leaves are narrow and small, and they are languishing, which is often called orchid stiff seedlings or weak seedlings and diseased seedlings.

In the simple **, we have received a lot of orchid friendly comments, let's talk about how to rejuvenate the weak seedlings of orchids.

Regarding the rejuvenation of weak orchid seedlings, if you search for it, you will see a lot of articles about sharing experience. However, because of contradictions, people are often confused, such as some say that they should be nourished without fertilization, and some say that they should be constantly fertilized; Some say that you don't want light, but shade, and some say you want to have plenty of sunshine; Some say they want to turn over the pot, and some say they want to rest and recuperate; And so on, which made many Xinlanyou confused and confused.

Some are partial generalizations and lack of experience in raising orchids. As soon as you talk about weak seedlings, you will talk about it, but you don't know that the generation of weak seedlings is caused by different reasons, so it needs to be treated differently according to the actual situation, otherwise it is misleading Lan You, which may cause worse results.

There are many reasons for the emergence of weak orchid seedlings, and the author has roughly summarized themSix reasons, respectivelyExcessive dividing, old man germination, too many buds, diseased plant infection, tissue culture seedlings, poor maintenanceand so on, we have to deal with different things according to the causes of weak seedlings, so let's analyze them one by one and give appropriate treatment measures.

1. Excessive division leads to weak seedlings

1. Causes

Orchid friends know that orchids belong to clumping herbs, and the common propagation methods are branch propagation and sowing propagation (tissue culture is discussed separately), because seed propagation has very high habitat requirements and is more time-consuming, so most orchid friends take branch propagation.

Spread the strainIt is a way that relies on orchid pseudobulbs to sprout into seedlings and then divide them, which is generally divided once in about three years. In this way, the nutrients of the pseudobulb of the orchid plant can be supplemented by each other, and the orchid plant is sufficient, so that the orchid plant is robust; It can also cause a sense of crisis in orchid plants because of the branching, so as to increase the germination rate and increase the reproduction rate. From the perspective of actual cultivation experience, orchid bushes are generally better in more than 3 or 5 plants, which can promote germination and flowering; If there are less than 3 plants, it is not easy to bloom even if it sprouts.

However, due to the high cost of famous orchids, many orchid merchants and orchid farmers, in order to make more profits, will divide the plants, thus promoting the germination of orchids, and some are even divided into single plants.

Weak orchid seedlings are generally more fragile, so we must give a little more fertilizer when planting, and then water every day.

The first is to cultivate roots, and the root system of most weak seedlings is not very good, which requires us to cultivate a strong root system to have the possibility of rejuvenating orchid seedlings. The second is to promote seedlings, rational use of fertilizer to promote seedlings, don't care about whether they can bloom, first raise the seedlings.

Plant potted plants to a temperature of about 25 degrees Celsius, add fertile nutrient soil to the soil, fertilize them every half a month or so, and put them in a ventilated place.

First, the breeding method.

1.Temperature: Weak orchid seedlings are sensitive to the environment.

When curing, it is recommended to provide it with a temperature of 20-25. Try not to drop below 12 at night. It's good for its growth.

2.Light: Weak seedlings need to be cleaned, so the breeding environment must not have too strong light.

It is best to provide it with only a small amount of scattered light, which can inhibit transpiration, evaporate water, and reduce the burden on its roots. 3.Watering:

For weak seedlings with a small number of roots, excessive watering is not required. Because a small amount of root system is not enough for it to absorb a large amount of water, watering too much will only lead to the accumulation of water in the plant matter, which can lead to root rot. It is generally watered once every 10-15 days, and it is best to keep its plant material slightly dry.

4.Fertilization: Weak seedlings have few roots and a limited rate of nutrient absorption.

The nutrients in the plant material are sufficient for it to absorb. Therefore, there is generally no need for additional fertilization.

Second, the planting material is recommended.

When raising weak orchid seedlings, it is necessary to choose plant materials with soft texture, permeable sedan air, moderate fertility and certain orchid components. If possible, you can use resurrection soil. It contains a large amount of orchids, which can help the orchid absorb nutrients and close early water, so that new roots can grow faster.

The primary purpose of raising weak orchid seedlings is to make it rejuvenate as soon as possible, so that it can grow this strong seedling, so I have shared with you a lot of weak seedlings before some skills, so I would like to return to my grandson today to share with you, the three major mistakes in the process of maintaining weak seedlings must not be made, otherwise this weak seedling is difficult to rejuvenate.

1. Use some coarse planting material to raise this weak seedling.

Many flower friends may think that the roots of this weak seedling are weak, and it is easy to drive away the root system if you use fine planting materials, but it is actually very wrong, the weak seedling itself has fewer roots, so that it is easier to absorb water and nutrients, and it can also make it grow roots faster.

If we use too coarse planting material, its fit is not enough, and the weak seedlings will only become weaker and weaker in the later stage, so the best way to raise weak seedlings is to use some relatively fine planting materials, and the pot can not be too large, for example, I raise this weak seedling is to use a relatively small pot.

2. Raise weak seedlings and never use fertilizer.

I have shared with you before that raising weak seedlings can be properly literate, but if you don't use fertilizer at all, then where do the nutrients it needs to grow come from, and proper topdressing is also very critical, but you must grasp the number of times of concentration and quantity of fertilizer.

If your normal orchid may be used once in about ten days, then weak seedlings may take about 20 days to use once, the concentration should be appropriately low, the amount should be appropriately reduced, and the general use is to use this orchid nutrient solution to spray it leaves or irrigate roots.

If you really can't grasp it well, the easiest way is to bury a little magic fertilizer in the potting soil, the magic fertilizer is to release nutrients when the plant needs nutrients, and the nutrients will not be released if you don't need nutrients, so you don't have to worry about it hurting the roots, don't worry about affecting the growth of weak seedlings, and also allow the weak seedlings to absorb enough nutrients to let it grow more new roots.

3. Yin nourishment. Weak seedlings can be shaded for a period of time at the beginning but can not be long-term shade culture, if there is no light, then how can it carry out photosynthesis to accumulate nutrients to be able to rejuvenate, so proper light is still very critical, so this is the maintenance period of orchid weak seedlings, we are more likely to make these three major mistakes, timely correction and maintenance of weak seedlings can soon be rejuvenated.

1. What to do if the seedlings are weak.

1. Scientific soil distribution: When planting weak orchid seedlings, we must choose suitable planting materials. Because the root system of weak seedlings is very weak, it is necessary to plant with planting material with good permeability.

In addition, it is better to choose a planting material that contains orchid bacteria. Because they can assist orchid plants to absorb nutrients and help them grow better.

2. Proper shading: Orchids are more shade-loving, and their weak seedlings cannot withstand strong light exposure. Therefore, when maintaining weak seedlings, it must be placed in a semi-shady place to avoid it receiving strong direct light.

3. Water and fertilizer control: When raising weak seedlings, avoid large water and fertilizer. Be sure to strictly control the frequency of watering and fertilization, and do not water unless the soil is dry. Do not fertilize unless the root system of the plant is back to growing. so as not to cause an additional burden on its root system.

4. Keep it ventilated: When maintaining it, it is necessary to keep it ventilated so as to provide it with fresh air. This will help increase its growth and make it grow stronger.

2. Can you use raw sawdust to raise?

Sawdust can be used to raise weak seedlings of orchids, but it is best not to use sawdust alone to raise orchids. Because it is very permeable, it is very suitable for the root growth of weak orchid seedlings. But if only sawdust is used to raise, its nutrient deficiency weakness will be highlighted.

Therefore, it is best to use it with some planting materials that are well mantilized and buried.
