How to grow hydroponic vegetables, how to grow hydroponic vegetables

Hydroponics is a method of soilless cultivation that enables plants to grow and develop by providing adequate water, nutrients, and oxygen in the water. Hydroponic vegetable seeds.

Methods include seed selection, preparation of planting containers, seed germination, planting and management. The following is a detailed introduction to the hydroponic vegetable seed method.

First, choose seeds that are suitable for hydroponics. When choosing seeds, one should choose the right type of vegetable according to your preferences and the needs of the population. It is advisable to choose organic or non-GMO seeds that are of good quality and suitable for hydroponics.

Learn the basic information about the seeds, such as skin hardness, seed lifespan, and skin water resistance, etc., to choose a variety suitable for hydroponics.

Secondly, prepare the planting container. Planting containers can be specialized hydroponic pots, plastic pots, bottles, or other containers suitable for holding water. The size of the container should be determined according to the needs of the plant and the cultivation space to ensure that the plant has enough space to grow.

Third, seed germination. Soak the seeds in warm water for a period of time, depending on the size and firmness of the seeds, but in general, 4 to 24 hours is sufficient. Soaking helps the seeds absorb enough water and promotes seed germination.

Next, plant the seeds into prepared containers. Sponge blocks, rock wool blocks, algae hole plates, or alcohol cotton balls can be used as substrates for seeds. Spread the seeds evenly over the substrate and gently cover it with another layer of substrate, maintaining proper humidity.

Next, place the planting container in a well-lit area, but avoid direct sunlight.

Finally, the management of seeds. Regularly check the water level in the planting container and make sure that the water level is always at the appropriate height. This can be maintained by adding the right amount of water to the container.

In addition, check the nutritional status of the hydroponic solution, and adjust the formula and concentration of the culture medium according to the needs of the vegetables. Ensure that vegetable plants get enough nutrients during growth.

In addition to the above steps, it is also necessary to regularly check the growth of the plants, remove possible pests and diseases in time, and carry out timely pruning and support to promote the healthy growth of vegetables. In summary, the hydroponic vegetable seed approach involves several key steps such as seed selection, planting container preparation, seed germination, planting, and management. By following these steps, you can get healthy, organic hydroponic vegetables.

1. Container: When hydroponic vegetables, you need to prepare a clean foam water tank, and then put in a floating plate to fix the vegetables. 2. Seedlings:

Select healthy and disease-free vegetable seedlings and cut off their rotten roots. 3. Hydroponics: Vegetable seedlings are planted in a tank with one-third of clear water.

4. Maintenance: Change the culture water every 3-4 days to avoid rotting vegetables.

1. Prepare the container

The first thing to do in the cultivation of hydroponic vegetables is to prepare a container, and you can use a foam water tank for home maintenance, which is very convenient. Then put a floating plate of the same size in the middle of the container to carry and fix the vegetables.

2. Vegetable treatment

Next, the hydroponic vegetables should be treated simply, the roots should be cleaned with water, and then the condition of the roots should be observed, and the old, weak, sick and disabled roots should be cut off and disinfected.

3. Hydroponics

Add an appropriate amount of water to the container, and add an appropriate amount of nutrient solution to the water to ensure the growth of vegetables. Put the processed vegetables in a container, fix them with a floating plate, and then drill a few small holes in the floating plate to increase its air permeability.

4. Later maintenance

After the completion of planting, you can carry out normal maintenance, ensure that there is water in the container at all times, need to change the water every 3 4 days, each time the water should be changed to observe the growth of the plant, and at the same time add an appropriate amount of nutrient solution to the water to ensure that the nutrients are sufficient.

1. Preliminary preparation: Hydroponic vegetables should choose a plastic box that can hold water as a utensil, and put a floating board into it. 2. Root treatment:

The vegetable roots are cleaned and pruned, and then soaked in potassium permanganate solution for disinfection. 3. Hydroponic method: insert the processed vegetables into the floating plate of the plastic box, then inject water and add nutrient solution.

1. Preliminary preparation

In the process of hydroponics, vegetables use water as the substrate, so it is necessary to choose a plastic box that can hold water as a hydroponic vessel, and clean and disinfect it to avoid residual harmful substances, and to put a floating plate into the plastic box to facilitate the fixation of vegetables, so as not to soak the whole plant in water and rot.

2. Root treatment:

Before hydroponic vegetables, take out the vegetables that need hydroponics, clean the roots with clean water, and then use sterilized scissors to cut off the dead roots and rotten roots of the roots, and then use potassium permanganate dilution solution to soak and disinfect for 30 minutes, and finally rinse the agent with water and hydroponics.

3. Hydroponic method

In the process of hydroponics, water should be injected into the plastic box, and then the processed vegetables should be inserted into the floating plate on the water surface to ensure that the root system is in contact with water, and the leaves can be located above the floating plate.

Hydroponic vegetable planting methods: preliminary preparation, root treatment, hydroponic methods.

1. Preliminary preparation

In the process of hydroponics, vegetables use water as the substrate, so it is necessary to choose a plastic box that can hold water as a hydroponic utensil, and clean and disinfect it to avoid the suspicion of residual harmful substances, and to put a floating plate into the plastic box to facilitate the fixation of vegetables, so as not to soak the whole plant in water and rot.

2. Root treatment:

Before hydroponic vegetables, the vegetables that need hydroponic should be taken out, the roots should be cleaned with water, and then the dead roots and rotten roots of the roots should be cut off with sterilized scissors, and then soaked and disinfected with potassium permanganate dilution solution for 30 minutes, and finally rinsed with water to rinse the Suixian agent and hydroponics.

3. Hydroponic method

In the process of hydroponics, water should be injected into the plastic box, and then the processed vegetables should be inserted into the floating plate on the water surface to ensure that the root system is in contact with water, so that the leaves can be in the position above the floating plate.

Advantages and disadvantages of hydroponic vegetables

1. High yield: The yield of hydroponic vegetables is several times or even more than ten times higher than that of traditional soil cultivation or substrate cultivation.

2. Good quality: Because the nutrient solution is used for planting, its nutrient supply is balanced, so the taste is better and the quality is better.

3. Safe and delicious: the green vegetables cultivated with nutrient solution can reach the A-level level, and the organic fertilizer cultivated can reach the A-level level.

4. Disadvantages: Generally, hydroponic vegetables are lighter in color, the stalks are longer, they look unenergetic, hydroponics and light can not be carried out at the same time, strong light will increase the water temperature, or you have to reduce the light, which makes the plant lack photosynthesis.

1. Make a hydroponic box

Before growing hydroponic vegetables, it is necessary to prepare a watertight hydroponic box, and it is recommended that you use plastic foam boxes. A float of the same size is placed on top of the box to carry the vegetables.

2. Handle vegetables

Before hydroponic planting, the vegetables should be treated simply, and the hydroponic vegetables should be selected first, and the roots should be rinsed 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 damage its roots when planting, and it is best to add the right 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.

Fourth, 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.

Hydroponic vegetable precautions

1. The environment of hydroponic vegetables should be kept warm and moist all year round, the temperature is between 10 and 25 degrees, and the minimum should be kept above 5 degrees, and the potted plants should be placed in a cool place after the temperature is higher than 30 degrees, so as to avoid excessive temperature, and if necessary, you can sprinkle water around to cool down.

2. It is not advisable to give too much light to the maintenance of hydroponic vegetables, the irradiation of light is easy to make the container or the root system of vegetables grow green algae, after the green algae wraps the root system or container, it will affect the root respiration of vegetables, easy to cause rotten roots, green algae rot regret emitting odor.

When <> planting hydroponic vegetables, it is necessary to provide them with a well-sealed cultivation plastic box, and it is also necessary to choose vegetables with excellent varieties and healthy and disease-free vegetables, and then rinse the root system of the plant with clean water, and then the vegetables can be planted in the hydroponic plastic box, and the culture water needs to be replaced every 7-8 days to make the hydroponic vegetables grow vigorously.

1. Provide containers.

When planting hydroponic vegetables, in order to choose a container suitable for growth, you can choose a cultivation plastic box with good sealing and suitable space, and then put the plastic box into the water for high-temperature cooking and disinfection, remove the bacteria and germs in the container, and also need to put a floating plate with the same width and length in the hydroponic box to facilitate the carrying of vegetables.

2. Vegetable selection.

When planting hydroponic vegetables, you need to choose a good variety of hectares and transport plants, and then treat them, you can use clean water to clean the soil on the vegetable roots, you also need to use scissors to eliminate the poison of the vegetable dry and rotten root system to cut off, and then apply potassium permanganate solution to the fracture of the root of the plant for disinfection.

3. Hydroponic method

When cultivating vegetables with water, you need to plant the treated plants in the hydroponic box, you need to be careful when operating, it is best not to shed and hurt the root system of the vegetables, so as not to reduce the survival rate, and you also need to add a few drops of nutrient solution to the hydroponic tank to provide the nutrients needed for the growth of vegetables and maintain their normal growth.

4. Replace the water.

Hydroponic vegetables have higher requirements for water quality, when breeding hydroponic vegetables, if the water quality becomes turbid and black, it will lead to rot of the root system of the plant, so that the vegetables grow poorly, and the culture water needs to be replaced every 7-8 days, and natural water or mineral water that is non-polluting and rich in a variety of nutrients can be used.

Generally speaking, hydroponic vegetables are highly effective and easy to manage, the main method is to disinfect the roots first, and then prepare an impermeable hydroponic box, the nutrient solution is reasonably prepared, the planting and sowing strengthen air circulation, and the weeding treatment is carried out irregularly after planting, and the water can be changed every 3 or 4 days.

For the best planting of hydroponic vegetables, generally speaking, it is best to clean the roots of the selected plants with water, and then disinfect them with a small amount of potassium permanganate solution, and then cut off the fibrous roots, dead roots, and excess lateral roots on the old roots to promote the growth of new roots.

It is best to choose an impermeable box for hydroponic vegetable containers, generally common potted shrubs or wooden boxes, with Styrofoam boxes are the best, and then inlaid with different foam plastic floating plates to load vegetable seedlings, and then fix the floating plates.

The most important thing for hydroponic vegetables is the vegetative growth of vegetables, so to ensure the quality of the nutrient solution, 1 gram of magnesium sulfate, 1 gram of potassium nitrate, 3 grams of potassium dihydrogen phosphate, 5 grams of urea, 1 gram of calcium sulfate, and 8 grams of zinc sulfate are added to dissolve the best.

Then the seedlings are placed in a mixed liquid substrate filled with grass charcoal and washed slag, the roots are put into it, and then 4 or 5 small holes are made on the floating plate to facilitate air circulation to promote the growth of the plants, and then an appropriate amount of nutrient solution is added to the substrate, and it is best to place it in a ventilated environment.

After planting, pay attention to the root depth can not be too large, generally ensure that the substrate floods the root part, when the sun is strong at noon, it is necessary to properly shade the sun, and often watering to ensure that there is always water in the box, in the process of plant growth, and to get rid of the surrounding weeds in time.

Hydroponic vegetables should also be frequently treated with water change, due to the long-term hydroponics inevitably has some germ residues, the water quality is best to the pH value of about rainwater, pond water, or river water is the best, if it is tap water at home, generally stand still for about 2 days, change the water every 3 or 4 days, and then add nutrient solution to the inside.
