Do I need to add nutrient solution to the water to grow vegetables in hydroponics?

Spinach is usually carried out from the soil due to land cultivation fees. Spinach and other vegetables are great for soil cultivation. It is easy to manage high-quality vegetables.

It can reduce the area, improve production and plants in multiple seasons. So how do you operate such a dirty spinach? Today, I'm going to introduce you to the technique of spinach, so let's see it!

Is it difficult to use water spinach? Place spinach seedlings in hydroponic containers with nutrient solution daily.

Enough. 1. Seed processing.

Before sowing, soak the seeds in 50 or more hot water for 5 to 8 minutes, the seeds are thinner, shorten the time, the intermediate should be stirred until it does not stop, avoid burning the seeds. Avoid burning seeds. Or soak in the agent for 20 minutes.

It is then dried in warm water, soaked in warm water for about 25 to 30 degrees or two days. Remove the clean dry package from a clean damp cloth and place it in the incubator at the spinach germination temperature.

2. Seedlings and seedlings.

When the seeds are broken, they place the seeds in a clean, non-dirty seedling tray, be sure to clean and sterilize the seedling tray, then put both seeds in the pot and finally use small sand mixed with grass ash, covering about 2 cm deep. After releasing the water, observe the situation every day and water it every day. As a result, in about three days, the spinach seeds will germinate.

3. Cultivation. Installation of cultivation facilities, plant containers, then sterilization**, configuration of nutritional solutions, configured according to the nutrient absorption characteristics of spinach. Seedlings with real leaves will be planted.

After cleaning the roots, place a small container or two types of seedlings, which are usually intense, and weak seedlings are placed in two. Pour some water and put the solution into the seedlings that will be slower after a few days. The small farm net in the village makes the farmers fashionable!

4. Cultivation management.

The nutrient composition is different from the nutrient structure of the unit. Usually grown in a 1 liter size container, the nutrients should be kept about 700 ml. There are more nutrients than plants in the seedling stage. The bottom of the container for growing spinach must have space for root stretching.

5. Pest control.

Soilless cultivation is very disgusting, but it is prone to over-disadvantages, or too much nutrition. In addition, insects do not pay attention. The main thing is that aphids can be used.

Aphids to suck the juice, generally use 50 anti-rock (necessary fog) 2000 3000 times solution or 40 alliance 1000 times liquid to prevent **. Is it difficult to use water spinach? Place the spinach seedlings in hydroponic containers with sufficient nutrient solution per day.

The above is a soil cultivation technique that can be collected for later use!

In fact, it is also necessary to increase the nutrient solution, so that the dish will grow more lush, and the constant will increase, which will also make its taste more fresh, crisp and delicious.

If you want to grow vegetables hydroponically at home, most of them do not need to add nutrient solution, and you can change the water frequently. For example, potatoes with a high survival rate can not be put into water when cultivating, only half of them can be put in, and it will grow buds in about three or four days, and seedlings will grow in a week. During the incubation period, the water needs to be changed frequently, about twice a week.

Yes, but it is necessary to pay attention to the concentration of the nutrient solution in the container. Because seedlings need a lot of nutrients when they grow. In general, when planting a one-liter container, the nutrient solution should be kept at about 700ml. More nutrients are needed during the seedling stage.

To grow vegetables in hydroponics, the water needs to be added with a nutrient solution, and it must be added, and the nutrient solution substance is kept at about 700 ml.

Yes, these vegetables can be supplemented with sufficient nutrient solution, which also has a great effect on their healthy growth and increased yield.

Nutrient solution alone is certainly not enough, it needs to be combined with water and fertilizer to make these plants more fertile and also make them grow faster.

No, the fertilizer required by hydroponic plants is completely mineral inorganic nutrients, and it is prepared with a variety of nutrients, and the nutrients in the nutrient solution are too single.

Generally, you can use the best hydroponic special nutrient solution on the market, and prepare the appropriate concentration according to the instructions, such as diluting 400 times or 1000 times, don't make a mistake about the proportion. When preparing, the tap water should be left for two hours to half a day, and after its temperature is close to room temperature and the chlorine in the water has volatilized, the concentrated nutrient solution should be added in proportion, and it will become a nutrient solution that can raise hydroponic plants.

Plants can be fed without nutrient solution, but it is difficult to grow in a healthy state.

Summary. The nutrient solution required by hydroponic vegetables mainly includes the following: nitrogen, phosphorus, potassium fertilizer:

These are the three main nutrients that are necessary for plant growth and promote the growth and development of plants. Trace elements: including iron, zinc, copper, manganese, boron, molybdenum, etc., although these elements only need trace amounts, they are also very important for the growth and development of plants.

Elements such as calcium, magnesium, sulfur, etc.: These elements are also very important for the growth and development of plants and can promote the healthy growth of plants. pH Regulators:

Hydroponic vegetables need to maintain a certain pH, usually in between, so a pH regulator is needed to regulate the pH of the water. The ratio of nutrient solution needs to be adjusted according to different vegetable types and growth stages, and some professional hydroponic vegetable nutrient solution formulas can generally be referred to for preparation. At the same time, it is also necessary to pay attention to the concentration of the nutrient solution, too high or too low will affect the growth and development of the plant.

At the same time, it is also necessary to pay attention to the concentration of the nutrient solution, too high or too low will affect the growth and development of the plant.

Are these vegetables harmful to the human body?

Dear to you, this kind of vegetable will not cause harm to the human body. These vegetables are communicating with genetic technology to alter their genomes to increase their nutritional value, disease resistance and yields. These changes are carried out through precise scientific methods and do not cause any adverse effects.

In addition, these vegetables have also undergone rigorous safety assessments to ensure their safety for humans. These evaluations include studies of the genome, protein, nutrient content, toxicity, and allergenicity of vegetables. Therefore, these genetically modified vegetables are safe and can be eaten as ordinary vegetables.

Of course, we should also pay attention to a balanced and varied diet, and do not rely on only one type of vegetables to ensure good health.

The water in the nutrient solution is the most proportional, and it is best to choose natural rainwater, which is the most important water source, which is not only very pure, but also contains a large number of trace elements, which can supplement the nutrients most needed for growth. If you use river water, the safety is not guaranteed, and it may contain chemicals, which can restrict the growth of vegetables. You can also use tap water after standing, and let it stand for a period of time to remove the chlorine inside, which will have less impact on vegetables.

According to the elements needed for the growth of vegetables, you can mix sodium, calcium, potassium, nitrogen, phosphorus, magnesium, etc., such as 70 grams of superphosphate, 10 grams of sodium nitrate, 40 grams of magnesium sulfate, 35 grams of potassium sulfate, 25 grams of ammonium sulfate, etc., mixed with water and stirred, the amount is not accurate, according to the different requirements of flowers, how much increase or decrease a little.

When blending, be careful not to use metal containers, otherwise it will affect the solution inside, you can use other materials, such as glass and ceramic, so as not to destroy the elements inside.

Cultivation methods of hydroponic vegetables

Method 1

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 old roots and rotten roots, 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.

Method two

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 board 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 hydroponics should be taken out, the roots should be cleaned with water, the dead roots and rotten roots of the roots should be removed, and then soaked and disinfected with potassium permanganate dilution solution for 30 minutes, and finally rinsed with water to rinse the 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, and the leaves can be located above the floating plate.

Try to avoid direct sunlight and it is recommended to keep it in a cool place.

Whether the vegetable can be poured with nutrient solution.

The nutrient solution can be poured with lead Sun Yu water for vegetables, because the general nutrient solution is artificially prepared, which is more in line with the nutrients required for the growth of vegetables and can promote the healthy growth of vegetables.

Nutrient solution watering method.

Time to pour the nutrient solution.

Hydroponic vegetables can be changed every 2-3 days at the beginning. When the plant grows vigorously, it can be cultivated with nutrient liquid in the Yinghuai section to ensure sufficient scattered light and promote the good growth of vegetables.

The correct way to pour the nutrient solution.

The method of watering vegetables with nutrient solution: first pour the nutrient solution into a container, mix the nutrient solution with water at a ratio of 1:500, and then spray the prepared nutrient solution on the leaves of the vegetables.

Precautions for nutrient solution for vegetables.

1.Water quality inspection: In the process of preparing nutrient solution, vegetables are mostly taken locally.

Due to the large differences in water quality in different regions, when applying the soilless cultivation technology in a certain area, it is necessary to investigate the water source used to prepare the nutrient solution. 2.Effect of different matrices on nutrient solution configuration:

When preparing nutrient solution for vegetables, it is necessary to consider the choice of soil and adjust the pH value of the soil to avoid adverse effects on the growth of vegetables.
