Which vegetables can be hydroponic and which ones are hydroponic

There are many kinds of vegetables that can be hydroponics, such as taro, garlic, potatoes, cabbage, etc., which are common and have a high survival rate of hydroponics. Taro: Soak the roots in water and change the water the next day.

Garlic: Arrange the garlic neatly, leave a gap, and put it in the water to grow garlic sprouts. Potatoes:

Soak half of the potato in water and it will sprout and sprout.

1. Taro. In addition to soil culture, taro can also be hydroponic. During hydroponics, soak the roots in water and change the water every other day, and it can survive without taking care of it. If you want to eat taro, you can switch from hydroponics to soil culture, and it will grow taro.

2. Garlic. Garlic hydroponics can be cultivated as a single piece or as a whole garlic. Place them in containers with gaps between each one as they will expand after absorbing moisture, and the purpose of leaving a gap is to prevent crowding.

At the beginning of growth, there is no need to change the water, only the amount of water added to the initial water level is sufficient. The water can be changed in the middle and late stages of cultivation, and after the water is changed, the green algae on the garlic head should be cleaned frequently.

Too much attachment of green algae can affect their respiration and affect their growth. In about a month, the garlic sprouts will be ripe and ready to be cut and eaten.

3. Potatoes. The hydroponic method of potatoes is different from the above cultivation methods, it can not put the whole potato into the water when cultivating, only half of it can be put to avoid rotting, it will sprout in about three or four days, and seedlings will grow in a week. During the cultivation period, the water should be changed frequently, and the frequency is once or twice a week.

Fourth, cabbage. Spread a piece of fresh, undamaged cabbage on top of the table, peel it until only the cabbage heart remains, then flatten the roots and place them in a container filled with water. Put it in a sunny place, change the water every other day, and it will grow roots in about a week.

Growing vegetables, we can hydroponic "like this", the roots are fast and germinate well, and the leaves are verdant and green.

Cultivars: lettuce, fungus, water spinach, purple back, leaf beet, endive, Beijing waterweed, watercress, in addition to some leafy vegetables, some fruit and vegetable vegetables can also be hydroponics, such as cucumbers, melons, tomatoes, etc.

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.

Hydroponic vegetables include lettuce, fungus, water spinach, purple back, leaf beets, endive, watercress, etc. 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.

Characteristics 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.

Hydroponic vegetables:

1. Lettuce. Hydroponic lettuce is very common, the best growing temperature is between 15 and 25, the temperature should not be too high or too low, below 15 will slow the growth, if the temperature is above 30, it will not grow well. Hydroponics is best in winter and spring, and the varieties should be selected during hydroponics, which is suitable for using loose-leaf lettuce varieties for hydroponics.

2. Spinach. When hydroponic spinach, it is necessary to pay attention to adding nutrient solution, but the concentration of nutrient solution should not be too high, and the concentration of nutrient solution can be appropriately increased as it continues to grow, otherwise spinach will grow poorly due to lack of nutrients. Suitable varieties should be selected for hydroponic spinach, and varieties with good disease resistance and strong ability to sprout should be selected.

3. Cress. Compared with other vegetables, watercress is more suitable for hydroponics, so the taste of hydroponics is better than that of soil culture. When hydroponic cress, seedlings with intact root system should be selected so that the growth of cress can be better. During hydroponics, there should be no shortage of water, and the nutrient solution should be supplied, but the concentration should not be too high.

Fourth, rape. When hydroponic rape, you can use glass bottles and mineral water, which can be convenient for water change, and you need to change the water frequently during the maintenance period, you can change the water once every 5-7 days, and the water quality should be clean. The suitable temperature for hydroponic protection is between 12 and 25 °C, and the plants are provided with sufficient light.

5. Amaranth. Amaranth can also be grown hydroponically, but it needs to master a certain hydroponic technology, it likes to grow in a warm environment, heat resistance, the suitable growth temperature is between 20 and 27, when the temperature is lower than 20, the growth will be slow. If the temperature is below 10, it will be difficult for the seeds to germinate.
