Planting vegetables without soil as long as water is not good?

Absolutely.

Now there is a cultivation called hydroponic vegetable cultivation. Hydroponics is the science of growing plants without soil. In hydroponics, plants are grown in an aqueous medium infused with macronutrients and micronutrients needed to thrive.

Generally speaking, hydroponic vegetables are highly effective and easy to manage, and the main method is to disinfect the roots first, and then configure an impermeable hydroponic box, which is reasonable according to the liquid configuration. It is enough to sow seeds, strengthen air circulation, carry out weeding treatment irregularly after planting, and change the water every three or four days.

Yes, you can buy nutrient solution to cultivate.

1. Rush this humus, humus soil is made of deciduous leaves, withered grass and other substances accumulated and fermented, and can be mixed with humus and garden soil when used, and put away after screening and drying. The humus soil is rich in scattered humus, with good fertility and drainage, and is light and loose.

2. Garden soil, that is, the soil used for planting in vegetable gardens or nurseries, is relatively fertile and can be used after disinfection.

3. It is better to mix peat soil with perlite or vermiculite, these substrates can increase soil porosity and beautify the soil.

1. Temperature: Green vegetables have a strong ability to resist cold, and they like a low temperature environment, and can grow normally in 10 or 20. Green vegetable seeds can germinate and grow at a minimum of 5, and if they are placed at 20 25 conditions, they can germinate in three or two days.

2. Moisture: Green vegetables need a lot of water at all stages from seed germination to flowering and fruiting. Its leaves are large and thick, and water is easily evaporated, so it is important to keep the soil moist and not let the soil run dry.

3. Soil: Its root system is very well developed and has many fine roots, so a deeper soil is its favorite. It is best to have a weakly acidic or neutral soil, and it should be loose and aerated to allow the greens to grow better.

4. Flower pot retreat: It is best to use a tile pot with a height of more than 20cm to plant green vegetables, which can make the root system of green vegetables grow better, and the tile pot with good ventilation and water permeability can also make it grow better.

5. Sowing: Before sowing, green vegetable seeds need to be dried in the sun for three to four hours. Then, soak in warm water at 50 degrees for half an hour, then soak the seeds in cool water at 25 degrees for three hours, and finally wait for the budding to emerge in an environment of 20 degrees before sowing.

6. Summer: It is a plant that prefers low temperatures, so when the temperature is high in summer, it is easy to cause the quality of green vegetables to be poor, so the temperature should be reduced to below 30 as much as possible, and the soil moisture should be kept sufficient.

Greens need fertile, well-judged sandy soil with a moderate pH and rich in organic matter and nutrients. The suitable soil is generally peat soil, sandy loam and depression loam.

Green soil refers to the biologically active layer in the soil and is often used to grow organic vegetables. With proper treatment, green soil can provide the right nutrients and water for vegetables, thus promoting healthy growth. However, if the soil contains harmful substances such as heavy metals, pesticides, fertilizer residues, etc., the vegetables grown can pose potential health risks.

Therefore, before choosing to use green soil for growing vegetables, it is necessary to conduct a preliminary test on the soil and ensure that the quality of the soil meets the safety standards. For example, the use of certified organic fertilizers and suitable treatment methods can effectively reduce soil pollution. In short, the green soil planting itself is safe, but the stool should ensure that the soil is safe and does not contain any harmful substances.

Summary. Growing vegetables has positive health effects, but it is also important to avoid things that can be harmful to your health, such as the use of large amounts of chemical fertilizers and pesticides, or the retention of too much water in the soil for long periods of time, and the irrational use of fertilizers and pesticides.

Growing vegetables has a positive impact on health, but it is also important to avoid things that may be harmful to your health, such as the use of chemical fertilizers and pesticides, or the retention of too much water in the soil for a long time, and the irrational use of fertilizers and pesticides.

Therefore, it is necessary to pay attention to ensuring the quality of vegetables and ensuring that the planting environment is conducive to good health. In addition, the use of organic fertilizers can save fertilizer inputs and reduce pollution, and traditional Chinese medicine disease resistants and insect repellents can be used to naturally maintain agricultural plants.

Are there any harmful substances in the clay?

Generally speaking, there are not many harmful substances in the clay demolition, and the common harmful substances are mainly heavy metal elements. However, there are also some organic substances that may also exist in the soil, such as organic pollutants, long-term effective pesticide residues, etc., which are harmful to people and the environment. Therefore, it is necessary to measure the potential hazards of hazardous substances in the green soil in order to take measures to protect the environment in time for Tachibana Goki.

Isn't it harmful to have golden lins in the green soil?

Yes. You can't grow vegetables, can you?

You can also.
