The nutritional formula of hydroponic vegetables, what is the nutrient solution of hydroponic vegeta

I don't know what kind of vegetables or flowers you are going to plant, there should be different needs for different varieties, so the preparation is also different, you must know the attributes, pH value, etc., it is quite complicated, if you want to plant well, you have to lay a good foundation. If it's fun, go to the flower and bird market to buy it, and it won't cost much, if you want to develop, just check it on the Internet. I don't remember the specific net.,I'm sorry.,There's a lot of related stuff to find the preparation of the nutrient solution.,I believe it can be useful to you.,Take your own time,

The main source of nutrients for hydroponic vegetables comes from water quality, so nutrient solutions are required. It can be prepared with 25 grams of ammonium sulfate, 35 grams of potassium sulfate, 40 grams of magnesium sulfate, 10 grams of sodium nitrate, and 70 grams of superphosphate. It can also be mixed with zinc sulfate, superphosphate, magnesium sulfate, ammonium molybdate, copper sulfate, iron sulfate, potassium nitrate, boric acid, calcium nitrate, manganese sulfate and water.

The nutrient solution can be added dropwise according to the growth of the plant, and the effect is very good.

1. Water use. 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.

2. Nutritional ratio.

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.

3. Precautions.

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.

The concentration range of the individual elements in the nutrient solution is as follows: (in mg L).

cu：。Preparation method of nutrient solution for home-type hydroponic vegetables.

When preparing, salts containing calcium and iron can be dissolved in water to make solution A, and compounds containing other nutrients can be dissolved in water to make solution B.

The scope of use of nutrient solution is mainly used for the production of hydroponic leafy vegetables in the home mini system, which can be cultivated continuously for 120-200 days and the growth state is good.

A method of making your own hydroponic nutrient solution.

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.

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.

Commonly used several nutritional stool liquid formulas 1, 10 grams of sodium nitrate, 70 grams of superphosphate, 25 grams of ammonium sulfate, 35 grams of sulfate bell, 40 grams of magnesium sulfate. Usage: When using the above formula to prepare the nutrient solution, first mix it with water, and then add the mixed trace elements in the ratio of 3 grams per 100 liters of water before it can be used (trace elements are usually mixed into powder with 100 grams of ferrous sulfate, 14 grams of boric acid powder, and 10 grams of manganese sulfate) 2, nitrate and potassium grams, boric acid grams, calcium nitrate grams, manganese sulfate grams, superphosphate grams, zinc sulfate, magnesium sulfate, copper sulfate, iron sulfate, ammonium molybdate.

Usage: When using, mix various rough elements together, add 1 liter of water, and it becomes a nutrient solution. In the preparation of the above-mentioned nutrient solution, the type and dosage of the elements can be increased or decreased according to the different requirements of different flowers.

There are many ways to grow vegetables, so let's talk about the simple methods of hydroponic vegetables.

01 In order to do a good job in the hydroponic of vegetables, we need to prepare the following materials: hydroponic containers, culture liquid, sand, etc.

02 First of all, we have to raise seedlings first, there are many ways to raise seedlings according to our own needs, or we can also buy ready-made vegetable seedlings directly.

03 Then transplant the cultivated vegetable seedlings or ready-made vegetable seedlings into the hydroponic container, and the hydroponic container should be as large as possible, so that the vegetables will grow faster.

04 In addition, when hydropruling vegetables, the culture medium we use should be changed regularly, because the growth of vegetables depends entirely on the culture medium.

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.
