How to grow hydroponic vegetables, how to grow hydroponic vegetables

Hydroponic vegetable cultivation methods at home:

1. Make hydroponic tanks.

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.

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.

1. 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.

2. Hydroponic method.

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.

3. 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.

4. Maintenance 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.

Hydroponic vegetables should first be prepared in a container, which can be cured in a foam tank, and then a floating plate should be prepared to hold the vegetables. The vegetables are treated, their roots are pruned and disinfected, and then the vegetables are placed in a container and fixed with a floating plate. After that, you can carry out normal maintenance, change the water once every 3 or 4 days, and add nutrient solution to ensure that the nutrients are sufficient.

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.

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.

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.

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.

The main method of hydroponic vegetable planting is to disinfect the roots first, and then prepare an impermeable hydroponic box, the nutrient solution is reasonable with the reputation of the system, the planting and sowing to strengthen air circulation, and the weeding treatment is carried out irregularly after planting, and the water can be changed every 3 4 days.

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.

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 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 to avoid the whole plant being soaked in water and rotting.

2. Root treatment: Before hydroponic vegetables, take out the vegetables that need hydroponics, clean the roots with 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, so that the leaves can be envied above the floating board.

Advantages and disadvantages of hydroponic vegetables

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. Good quality:

Because it is grown with nutrient solution, the nutrient supply is balanced, so the taste is better and the quality is better. Safe and delicious: Green vegetables cultivated with nutrient solution can reach grade A, and those cultivated with organic fertilizer can reach grade AA level.

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, and strong light will increase the water temperature, or it will have to reduce the light, which makes the plant lack photosynthesis.
