Why vegetables can be grown on water or on posts

Growing vegetables on water or on posts generally refers to hydroponic vegetables or soilless vegetables.

Hydroponic vegetables are a method of growing vegetables in water. In this case, the plant is not planted in the soil, but in a nutrient solution. The nutrient solution provides the plants with the water, nutrients and trace elements they need to grow.

By precisely controlling the amount and timing of the nutrient solution, you can ensure that the water and nutrients needed for plant growth are accurate**.

Soilless cultivation refers to the growth of plants in an environment without soil. This is usually done indoors or in a facility, using a special medium such as rock wool, sand, or perlite to immobilize the plants. The medium can contain the water and nutrients that the plant needs to grow.

The main advantage of these methods is their ability to provide plants with the essential elements they need to grow, while being protected from soil contamination, pests, and continuous cropping obstacles. In addition, they are not limited by soil texture and location and can be done anywhere, including in urban environments or hard-to-access locations.

However, these methods require specific equipment and skills, including configuring and managing nutrient solutions or media, as well as ensuring that plants are properly lit and warm. In addition, the cost of these methods can be higher than traditional soil cultivation methods.

Overall, growing vegetables on water or on posts is feasible, mainly because they provide the basic elements that plants need to grow and are not limited by the soil. However, this requires specific equipment and skills and can be more costly than traditional soil cultivation methods.

If you want to operate this cultivation method, you must first understand the conditions you can provide for the vegetables and the growing conditions of the vegetables you want to grow. If it is suitable, it can be cultivated.

That's soilless farming.

Vegetables that can be grown on the surface of the water are: celery, sweet corn, callus white, lettuce, chrysanthemum, etc.

Water vegetables refer to vegetables grown on water under soilless conditions. In the eyes of many people, if you put vegetable seedlings in water without soil, they will die. In fact, all plants have the potential to grow in water, and it does not necessarily have to be soil to grow, the soil only plays the role of fixing plants.

Vegetables that are especially suitable for growing on water are celery, sweet corn, callus white, lettuce, chrysanthemum, etc.

In order to grow vegetables on the water, it is necessary to build a floating frame on the water, usually with foam underneath, and then fixed with plastic or wood. Dig some round holes with a diameter of 5 cm in the foam, and put the vegetable seedlings in the holes to let the roots come into contact with the water. Although there is no soil, the nutrients of the water used to grow vegetables must keep up, which should be tailored according to the nutrients required by the vegetables grown.

Vegetables grown on the water are more tender than those grown in the soil, and if they are grown organically, they will be more popular with the public. In addition, because it is a new production technology, the scale of investment is not large, and the production risk is small, so the market prospect is promising. Water vegetable cultivation is suitable for all regions of the country.

The one-time investment of one mu of pond does not exceed 4,000 yuan, including the cost of floating frame, fertilization, seedling raising and other expenses built in the first year.

Hydroponic vegetables refer to vegetables that are cultivated in the form of traditional soil cultivation in which most of the roots grow in the nutrient solution layer and only provide water, nutrients and oxygen to them through the nutrient solution. Hydroponic vegetables have a short growth cycle and are rich in a variety of vitamins and minerals that are essential for the human body.

Hydroponics is a type of soilless culture, classified as substrateless cultivation, the type of substrateless cultivation refers to the environment where the plant roots grow without substrate to fix the root system, and the root system grows in a nutrient solution or moist air containing a nutrient solution, but some substrates may be used when raising seedlings.

Features of hydroponic vegetables:

1. The root system is dominated by milky white capillary roots, which are used to absorb water and nutrients;

2. The root system adapts to the aquatic environment, and there are some aerial roots on the periphery to absorb oxygen;

3. The growth cycle is short and the market is early.

Vegetables can be grown.

In the summer, a large number of fruits and vegetables are also on the market, such as eggplant, pepper, beans, bitter gourd, loofah, etc., which are currently very popular vegetables. But these vegetables are all grown in the vegetable garden. Are there any vegetables that are grown in paddy fields?

In fact, there are also a lot of vegetables that are planted in paddy fields, and you have come up with four kinds of vegetables, which ones do you know?

When it comes to vegetables that can be grown in water, the first thing that comes to the farmer's mind is the lotus root. It is estimated that many people are like farmers, lotus root is a vegetable that grows in water, and the nutritional value is still very high. Every year in the summer, after the dog days, the lotus root harvest begins.

At this time, it is the season when lotus roots are on the market in large quantities. In the past, there was a custom of eating lotus root during the summer season. However, at this time, it is all tender lotus roots, and if you like to eat old and ripe lotus roots, you have to wait until after mid-September.

Lotus root is a perennial root-bearing aquatic herb that is sown in April every year in a live seeding manner. This vegetable is very water-loving and does not have strict soil requirements, so it is very suitable for growing in paddy fields or ponds.

The second type of vegetable that can be aquatically grown is water spinach. Some people may feel strange, isn't water spinach grown in vegetable patches? How can hydroponics be done?

In fact, water spinach is amphibious, mainly planted in vegetable gardens in the south, and generally planted in paddy fields in the north.

Water spinach is highly adaptable, it is resistant to both drought and waterlogging, and it is also very heat tolerant. The rhizomes and leaves of the water spinach can be reproduced, and the farmer put the roots of the water spinach in a pot of water before, and it actually came alive after a few days. Then I often changed the water for it, and this pot of water spinach is like a pothos, lush and beautiful.

If you want to grow vegetables on the balcony, water spinach is a good choice, it is easy to survive, and it is easy to manage, you can cut it once and grow it like a leek.

The third is the white cocoon, which is also called cocoon melon and bamboo shoots, which is a perennial root-bearing aquatic herb of the Poaceae family, mainly feeding on its fleshy tender stems. This crop is more common in the south, and it used to be cultivated more often, mainly by ponds or paddy fields. The plants look like grass seedlings, but are very tall.

During the planting process, the water-soluble fertilizer of fertile leaves can be appropriately applied.

The last one is taro. Taro is also an amphibious plant, which can be grown in vegetable gardens and paddy fields, but the yield of aquatic taro is higher. For taro, farmers prefer taro stalks, which are more delicious than taro.

When I was a child, the family often used taro stalks to make sauerkraut to eat, at that time, every household would make a lot, in summer and autumn, use sour taro stalks to cook vegetables and eat, it is especially a meal. Now that the standard of living has improved, few people in the village grow taro, so the sauerkraut made from taro stalks is also difficult to eat.

Can you grow vegetables in water? Soilless cultivation can now be carried out in water, that is, water planting, but a certain amount of nutrient solution is added before vegetables can be grown.
