How should I fertilize vegetables when growing them hydroponically?

Some friends don't like to grow hydroponic plants at home, don't like to look at the soil on the table, are afraid that the house is dirty, or have a habit of cleanliness, so they can grow hydroponic plants. Prepare some clean water and containers where hydroponic plants can be grown. It is not necessary to prune as often during the curing process.

Plants also need water, oxygen, light, and proper fertilizer to grow in water, and indoor hydroponic plants also need regular fertilizer supplements to grow well.

If it is a hydroponic plant that has just been planted and the bottom of the branch has not yet taken root, it is 3 to 5 days to grind the water once to maintain the activity of the water and promote the roots of the plant. If it is a hydroponic plant with good roots, you can wait until the water is dark before changing the water.

When changing the water of hydroponic plants, if you find that the root type is rotten, rotten or wilted, the diseased roots should be cut off, the roots of the plants and the surface of the container should be properly cleaned, and replaced with clean water. Plants provide most of their nutrients through their roots, and hydroponic plants also need to be fertilized with water-soluble fertilizers. In general, water contains a lot of calcium, magnesium, sodium, chlorine, more tap water, and higher levels of boron and plutonium.

Nutrients that are lacking in water.

There are iron, potassium, phosphorus, nitrogen, and some trace elements.

Therefore, the preservation of hydroponic plants cannot be fertilized casually, and water-soluble fertilizers can be supplemented regularly. Also pay attention to fertilizing hydroponic plants. Stop fertilizing in autumn when the temperature gets colder.

In spring and summer, a thin layer of fertilizer can be applied every 4-6 weeks. The fertilizer concentration is much smaller than usual. Usually around 1 to 10.

If you find that the leaves of the hydroponic plants you care for become pale and the leaves grow smaller and smaller, you should spray foliar fertilizer regularly, and water can supplement the water-soluble fertilizer.

In order to achieve the best water feature effect, water feature plants can be grown with bottled spring water, rainwater well water, tap water contains a lot of chlorine and lacks natural nutrients, so it can be used in a container for another 2 3 days.

When we raise flowers, we will find that many flowers can be grown by hydroponics. The water feature grows a little slower, but it grows normally, and it is nice to watch the roots grow when placed in a transparent water feature container. Hydroponic plants can grow in them as long as they are watered, but the nutrients disappear after a period of time.

Because there are not many nutrients in a simple water feature. If we want to raise water well, we need to fertilize it regularly. So, how should hydroponic plants be fertilized and fertilizer selected?

Hydroponic plants do not use fertilizers with those pellets. The granular fertilizer is fat, which is a fast-acting fertilizer, and is poured on the silt soil. It can be quickly mixed into pots.

soil, which slowly absorbs the roots, but if we use it on hydroponic plants, it will create a situation of small roots. Because the fertilizer content in the aqueous solution is too high.

Produces small roots.

There are many formulas of hydroponic vegetable nutrient solution, widely used Versailles nutrient solution potassium nitrate, calcium nitrate, ammonium phosphate, magnesium sulfate, ferric chloride, potassium iodide, to change the water frequently, due to the long-term hydroponics inevitably have some germ residues, pond water, or river water is the best, if it is the tap water at home for about 2 days, change the water every 3 4 days, and then add the nutrient solution dropwise to it.

Hydroponic plants can not be fertilized indiscriminately, and some water-soluble fertilizers can be supplemented regularly. It should also be noted that after the temperature gets cold in autumn, you should start to stop fertilizing, and you can give a thin fertilizer once in 4 or 6 weeks in spring and summer, and the concentration of fertilization is much smaller than usual, about 1 10 usual.

Hydroponic vegetable nutrient solution:

The nutrient solution used in hydroponic vegetables is an aqueous solution that dissolves fertilizer in water and absorbs it through the roots of vegetables to provide water and nutrients necessary for the growth and development of vegetables. The preparation and management of nutrient solution is a key technology in hydroponic technology, which plays a decisive role in the growth of vegetables.

The main fertilizers used for the preparation of nutrient solution are: calcium nitrate, potassium nitrate, nitric acid, magnesium sulfate, potassium silicate, potassium dioxide phosphate. Micro fertilizer has:

Chelated iron, sodium borate, manganese sulfate, copper sulfate, zinc sulfate, ammonium molybdate. The specific dosage and concentration ratio of nutrient solution vary according to the different types and varieties of vegetables, the different geographical conditions of the cultivation place, and the different seasons. In the process of cultivation and management, it is necessary to observe and adjust in time according to the actual growth of vegetables.

Nutrient solution preparation is the core technology for the normal growth of hydroponic vegetables. At the same time, it is also the foundation and key to soilless culture. According to the nutrient demand for plant growth, a solution prepared by dissolving a certain amount of fertilizer in water in an appropriate proportion is called nutrient solution.

The success of hydroponics depends to a large extent on the formulation and concentration of the nutrient solution, the ratio of various nutrients, the pH, the liquid temperature, and whether the management of the nutrient solution during plant growth can meet the requirements of each different growth stage. Only by adopting the correct formula, preparing and managing the nutrient solution according to the appropriate method, so that the plant is in the most suitable nutrient solution environment at any stage of growth and development, can the plant use more energy for growth, flowering and fruiting, so as to obtain rapid, high-yield and high-quality cultivation results.

Hydroponic vegetables, of course, are generally used liquid fertilizer, this has the corresponding fertilizer suitable for this hydroponic crop, if only the leaves are long, it is mainly nitrogen fertilizer, if you want to flower and fruit, then there is also phosphorus and potassium fertilizer.

Hydroponic vegetables need liquid fertilizer, and potassium dihydrogen phosphate fertilizer adjusted at the watering point can be used.

Hydroponic plants can use nutrient solution, there is a special hydroponic nutrient solution, which can be purchased in general florists, and the dosage can be added according to the instructions, not too much, to avoid fertilizer. You can also use compound fertilizer, which contains elements such as nitrogen, phosphorus and potassium, which can be diluted directly into water, and used once a month, not too often. In addition, potassium dihydrogen sulfate can also be used, which can be added after water change, which can promote the normal absorption of nutrients and is beneficial to growth.

1. Hydroponics

Hydroponics is a new type of soilless cultivation of plants, also known as nutrient hydroponics, the core of which is to directly infiltrate the root system of plants in the nutrient solution, which can replace the soil and provide water, nutrients, oxygen and other growth factors to plants, so that plants can grow normally.

2. Application of hydroponics

It is used for hydroponic vegetables to cultivate pollution-free green food, which is healthy and safe, and is highly valued by people.

Used for hydroponic flowers Hydroponic flowers have the advantages of cleanliness and hygiene, convenient maintenance, etc., especially suitable for indoor furnishings, and are deeply loved by consumers.

Used for the cultivation of medicinal plants Many medicinal plants are root plants, the growth environment of the roots is very critical, hydroponics, especially aeroponics can provide a good growth environment for the roots of medicinal plants, so the planting effect is very obvious.

3. Hydroponic vegetables

Hydroponic vegetables refer to vegetables that are cultivated in the form of traditional soil cultivation in which most of the roots grow in the nutrient solution layer and only provide water, nutrients and oxygen to them through the nutrient solution. Hydroponic vegetables have a short growth cycle and are rich in a variety of vitamins and minerals that are essential for the human body. Hydroponics is a type of soilless culture, classified as substrateless cultivation, the type of substrateless cultivation refers to the environment where the plant roots grow without substrate to fix the root system, and the root system grows in a nutrient solution or moist air containing a nutrient solution, but some substrates may be used when raising seedlings.

4. How to plant hydroponic vegetables

Preparation. If you want to grow vegetables hydroponically, you first need to prepare a suitable container, generally you can use a foam box to hydroponics, the box is required to be watertight, you need to clean it before use, and then you need to prepare a foam board, so that when hydroponic vegetables, it can play a role in fixing vegetables.

Hydroponic methods. Select vegetables suitable for hydroponics, rinse the soil with water for its roots, and cut off some excess roots, and finally disinfect its roots with a special disinfection solution, dig a small hole in the foam board after processing, and fix the vegetables into it, and the water level in the hydroponic box should just come into contact with the vegetable roots.

Change the water regularly. When hydroponizing vegetables, you need to change the water regularly, generally every 5 days or so to replace the best, must not change the water for a long time, otherwise the water quality deteriorates, the vegetables will rot, pay attention to the tap water hydroponics, you must first let the water stand for about 2 days before use.

Conservation management. After the hydroponic vegetables are planted, they need to do a good job in maintenance management, and they should often add nutrient solution to the water every day, so that the vegetables can grow vigorously, and the environment for the maintenance of hydroponic vegetables requires warmth and ventilation, and the vegetables should be exposed to the appropriate light, otherwise the environment is not suitable, and it will also have a negative impact on the growth of hydroponic vegetables.

Generally, it is watered three times a day, not near the roots, but close to the neck. Fertilization is farmhouse fertilizer or some nitronitrogen and phosphorus-containing fertilizers.

1. Different growth stages of vegetables require different fertilizer formulas, and water-soluble fertilizers of all elements are needed. Generally, the fertilizer is dissolved in a bucket and then poured into a fertilizer pond filled with water to check whether the EC value meets the standards for vegetable growth.

2. After the vegetable seedlings are slowed down, fertilizer is brought every time they are watered, and the water and fertilizer utilization rate is high, so as to achieve the purpose of saving water, fertilizer and labor.

Old farmers generally carry out reasonable fertilization and watering through the phenomenon of vegetables, so as to effectively meet the nutritional needs of vegetables.

Make hydroponic tank: When hydroponic vegetables, use a foam box to put a floating plate as a hydroponic container. Handling vegetables:

After washing, prune rotten, withered roots. Hydroponics: Put the vegetables into the hydroponic box, inject water and an appropriate amount of nutrient solution, and fix the root system.

Planting and maintenance: change the water regularly during hydroponics to avoid the turbidity of the water and the breeding of bacteria.

1. Make hydroponic tanks

Hydroponic vegetables are different from hydroponic plants, hydroponic plants can be directly used in vases or fish tanks, but the volume of vegetables is larger, and it is necessary to make a watertight box, it is best to choose a foam box, and put a floating board according to the size of the foam box to play the role of carrying vegetables.

2. Handle vegetables

Select vegetables that need hydroponics, clean the soil on the root system, prune the rotten and withered roots with sterilized scissors, and disinfect them in potassium permanganate solution.

3. Hydroponics

When hydroponic vegetables, it is necessary to protect the root system to avoid damage to the root system and cannot grow normally, inject an appropriate amount of water after putting it into the hydroponic box, add a special hydroponic nutrient solution dropwise according to the size of the container and the amount of water, fix the root system of the plant, and soak it in the water with the nutrient solution to grow.

4. Planting and maintenance

Hydroponic vegetables also need to change the water regularly, if the water is not changed for a long time, the water quality becomes turbid and will breed bacteria, and the vegetables will die when it is serious, the water will be changed every 7-10 days in spring and autumn, the water should be changed every 3-5 days at high temperature in summer, and the water should be changed once a month at low temperature in winter, and the nutrient solution will be dropped after the water change.

<>1. Make a hydroponic box: Before planting hydroponic vegetables, you should prepare a watertight hydroponic box, and it is recommended that you use a plastic foam box. It is also necessary to place a floating board of the same size on the box banquet, the purpose of which is to carry vegetables.

2. Treat vegetables: Before hydroponic planting, it is necessary to carry out a simple dry and auspicious treatment of vegetables, and first select hydroponic vegetables and rinse the roots with clean water. Then comb its roots, cut off its dead roots and rotten roots with scissors, and then disinfect it with potassium permanganate.

The disinfected root system should not be directly hydroponic, but should be rinsed with clean water before colonization.

3. Hydroponics: Be careful not to hurt its roots when planting, and it is best to add an appropriate amount of nutrient solution to the hydroponic box. The root system of the seedlings should be planted well, and there should be water in the hydroponic tank at all times.

4. Planting and maintenance: Pay attention to changing the water after planting, because there will be a lot of bacteria in the water during hydroponics, and the water quality will deteriorate over time. Therefore, it is necessary to pay attention to the water exchange, which can be used from rainwater, water from ponds, or water from rivers.

How should hydroponic flowers be fertilized? Keep these points in mind!

Many friends have hydroponic flowers and plants at home, and the cultivation of hydroponic plants is more labor-saving, but they also need to pay more attention to daily life, such as fertilization.

Let's take a look at the fertilization skills of hydroponic flower plants.

1. Fertilizer selection: There are special hydroponic plant nutrient solutions on the market, which should be used in strict accordance with the instructions, and the fertilizer concentration should be grasped well, and it should not be applied blindly, otherwise it may cause fertilizer damage.

In general, foliage plants should be mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. Flowering plants, especially in the stage of flower bud differentiation and flower bud development, should be mainly phosphorus and potassium fertilizers, supplemented by nitrogen fertilizers.

If the plant is malnourished in the summer and its growth is affected, a foliar urea solution can be sprayed.

3. Fertilization concentration: strictly control the concentration of fertilization when fertilizing, because all the nutrients applied are dissolved in water, when the concentration reaches a certain height, it will cause fertilizer damage to flowers, thereby affecting the growth of flowers, and even causing the death of the whole plant.

The concentration of fertilization of different flowers is different, and the flowers such as Hipberry Taro, Mini Monstera, Ruby Philostic Taro and other flowers are more resistant to fertilizer, and the fertilization can be thicker; Flowers with slender roots, such as Sihaibo, duck plantar grass, begonias, color-leaved grasses, etc., have poor fertilizer tolerance, and fertilization should be lighter.

Hydroponic flowers should also be determined according to the strength of the plant growth potential to determine the application concentration, generally speaking, the growth of strong plants fertilizer tolerance is stronger, fertilizer can be relatively thicker, on the contrary, it should be lighter.

When indoor hydroponic flowers are malnourished, fertilization should be stopped or the concentration of fertilization should be reduced to avoid fertilizer damage.

4. Fertilizer treatment: If the flowers and leaves are weak after fertilization, the leaf surface loses its luster, and the root system rots and smells, it is the characteristic of fertilizer damage.

Once the above situation occurs, the rotten roots should be cut off in time, replaced with clean water and placed in a shady place for maintenance, change the water 1 time a day, and check the roots of the flowers, cut off the rotten roots in time, until the new roots germinate again, and then transfer to normal maintenance.
