The method of hydroponic culture for rooting of plants and flowers

Hydroponic flower culture is a new generation of high-tech agricultural project, which adopts modern bioengineering technology and uses physical, chemical and biological engineering means to domesticate ordinary plants and flowers so that they can grow in water for a long time. Hydroponic flowers are full of fragrance above and fish swimming below, which is hygienic, environmentally friendly and convenient, so hydroponic flowers are also known as "lazy flowers".

1. Large plants that have been formed and have achieved ornamental effect can be mutagenized with clear water, such as cactus\ iron tree\ wooden pile bonsai. Because the goal of our cultivation of these plants is to maintain the original tree shape. However, gravel and perlite can only be used as the medium to fix the plant or keep the rhizome in the planting cup, while the mutagenesis of water root and aerated tissue must be carried out in the water environment. As for the plants that have completed the rooting stage, if they are moved to the mutagenic pool, the rhizome can be wrapped with a sponge and planted into the planting hole, or a planting cup can be installed and planted into the planting hole, which varies from variety to variety.

2. In terms of effect, it is the nutritional stress caused by clear water, which can accelerate the formation of aerated tissue of root system and the development of aquatic root, but from the point of view of cultivation, it is better to use appropriate concentration of nutrient solution in water, which is related to the fertilizer tolerance of mutated plants. It is necessary for cactus mutagenesis to remove native roots. Because the cactus is a succulent plant, drying for a period of time before induction is more beneficial to root induction, because succulent plants have more stringent requirements for water in the seedbed, too much is easy to rot, and too little causes root efficiency.

The method of changing water and washing roots of hydroponic flowers

Nowadays, many flower lovers like to try hydroponic flowers, some of which are bought directly from the market, but no matter they are bought or cultivated by themselves, it is especially important for hydroponic flowers to change water and wash their roots often. let's introduce the method of washing the roots of hydroponic flowers.

The management technology of hydroponic flowers changing water and washing roots is an important link to ensure the good growth of hydroponic flowers. So why do you want to change the water to wash the roots of hydroponic flowers?

First, the conditions for plant growth are mainly water, nutrients and air, the water and nutrients of hydroponic flowers can absolutely guarantee their needs, and the oxygen content of oxygen in water will gradually decrease with the growth of flowers, when reduced to a certain extent, it will affect the growth of flowers due to hypoxia, so it is necessary to change water to supplement new oxygen.

Second, the roots of hydroponic flowers grow in water, on the one hand, absorb nutrients in the water, on the other hand, discharge some organic matter into the water, there are also wastes or toxins, and deposit in the water. When these organic compounds are cultivated in soil, they mainly dissolve the nutrients which are not easily absorbed by the roots, while the wastes and toxins are distributed in the soil space or flow out from the leaks at the bottom of the basin, which will not be absorbed by the roots and affect the normal growth of flowers. On the other hand, there is no bottom hole in the hydroponic container, and these organic substances, wastes or toxins are all deposited in the water and are easily inhaled into the body by plants again, resulting in a vicious circle of repeated absorption, excretion, re-absorption and re-excretion. it is very unfavorable to the normal growth and physiological function of flowers.

Third, hydroponic flowers often apply nutritional fertilizer to the water, except for some mineral elements absorbed by the root system, the rest remain in the water, when the residual material reaches a certain amount, it will also do some harm to the flowers. Fourth, the roots of hydroponic flowers growing in water for a long time will produce a kind of mucus, which will not only affect the absorption of nutrients by flower roots, but also pollute the water. Due to the above reasons, hydroponic flowers must be managed by regular water change and root washing.

So, how do we master the technology and time of root washing by changing water?

Generally speaking, the water is changed as soon as it is dirty, usually in 20 days or so, and it is better to change it once in about 30 days. Of course, it should be flexibly mastered according to some conditions:

One is to change water regularly according to different kinds of flowers and their adaptation to hydroponic conditions. Some flowers, especially aquatic or wet flowers, are well adapted to the hydroponic environment. After hydroponic cultivation, they can continue to grow new roots on the original roots and grow well. For these flowers, the interval between changing water can be longer. However, some flowers do not adapt to the hydroponic environment after hydroponic cultivation, and their recovery and growth is slow, and even root rot occurs after hydroponic cultivation. For these flowers, in the early stage of entering the hydroponic environment, the water should be changed frequently, or even once a day or two. The times of changing water can not be gradually reduced until the new roots germinate and return to normal growth.

Introduction to the method of changing water and washing roots of hydroponic flowers

Nowadays, many flower friends who like flowers and plants are no longer satisfied with the flowers grown in the soil, and many of them are trying fresh breeding methods such as hydroponic culture. However, if you want to raise hydroponic flowers well, you must know when to change water and wash their roots. So why change the water and wash the roots of hydroponic flowers? Do you have any theories?

I. the reasons for washing roots and changing water for hydroponic flowers

First of all, the conditions for plant growth are mainly water, nutrients and air, the water and nutrients of hydroponic flowers can absolutely guarantee their needs, and the oxygen content of oxygen in water will gradually decrease with the growth of flowers, when reduced to a certain extent, it will affect the growth of flowers due to hypoxia, so it is necessary to change water to supplement new oxygen.

Secondly, the roots of hydroponic flowers grow in water, on the one hand, absorb nutrients in the water, on the other hand, discharge some organic matter into the water, there are also wastes or toxins, and deposit in the water. When these organic compounds are cultivated in soil, they mainly dissolve the nutrients which are not easily absorbed by the roots, while the wastes and toxins are distributed in the soil space or flow out from the leaks at the bottom of the basin, which will not be absorbed by the roots and affect the normal growth of flowers. On the other hand, there is no bottom hole in the hydroponic container, and these organic substances, wastes or toxins are all deposited in the water and are easily inhaled into the body by plants again, resulting in a vicious circle of repeated absorption, excretion, re-absorption and re-excretion. it is very unfavorable to the normal growth and physiological function of flowers.

In addition, the nutrient fertilizer often applied to the water by hydroponic flowers, except that some mineral elements are absorbed by the root system, the rest remain in the water, when the residual material reaches a certain amount, it will also do some harm to the flowers.

Finally, the roots of hydroponic flowers growing in water for a long time will produce a kind of mucus, which will not only affect the absorption of nutrients by flower roots, but also pollute the water. Due to the above reasons, hydroponic flowers must be managed by regular water change and root washing.

So, how do we master the technology and time of root washing by changing water?

Usually the water is dirty to change, generally in 20 days, 30 days or so, it is better to change once, of course, according to some conditions to be flexible.

According to different kinds of flowers and their adaptation to hydroponic conditions, the water should be changed regularly. Some flowers, especially aquatic or wet flowers, are well adapted to the hydroponic environment. After hydroponic cultivation, they can continue to grow new roots on the original roots and grow well. For these flowers, the interval between changing water can be longer. However, some flowers are not suitable for hydroponic environment after hydroponic cultivation, and their recovery and growth is slow, and even the root system will rot after hydroponic cultivation. For these flowers, in the early stage of entering the hydroponic environment, the water should be changed frequently, or even once a day or two. The times of changing water can not be gradually reduced until the new roots germinate and return to normal growth.

II. Requirements for water quality of hydroponic flowers

It's better to have pure water, or tap water. As the dissolved oxygen in water decreases with the increase of salt concentration, pure water belongs to desalted water with low salt content, so it is suitable for hydroponic flowers. In addition to low salt content, pure water has the advantages of good transparency and no pollution, so it is the most ideal water for hydroponic flowers. In addition, qualified drinking tap water can also be used for hydroponic flower culture. After filtration, disinfection and impurity removal, tap water has lower salt content and fewer germs to a certain extent. It is a more suitable water for hydroponic flowers. However, tap water disinfection commonly used liquid chlorine, excessive chlorine is harmful to flower roots, in order to release chlorine, need to be placed for a period of time before use. River water, lake water, pond water and well water are high in salt and can not be used for hydroponic flowers.

Special reminder: when washing the roots of hydroponic flowers, you must be gentle and not rough, so as not to destroy the tender roots.

In fact, hydroponic flowers should not only pay attention to root washing and water change, but also very important to choose utensils of the right size. Because hydroponic flowers can show their perfection only in transparent utensils. So flower friends must not ignore the choice of utensils!
