Why do the roots of hydroponic plants not rot

It's going to rot. If you want not to rot the roots, you can only change the water frequently. In general, roots also need oxygen, just like the soil needs to be loosened when planting, and if there is not enough oxygen in the water, it will rot. Therefore, change the water frequently, or add oxygen to the water.

Reasons why the roots of hydroponic plants do not rot:

1. The dissolved oxygen content in hydroponic water is high, and plant roots will not die due to lack of oxygen.

2. Leave half of the roots in the water and expose the other half to the air, so that the oxygen supply to the roots of the plant can greatly increase the sleepiness, which can effectively reduce the occurrence of root rot.

3. The water quality is good, which ensures the normal growth of plants.

4. The temperature is moderate, and there is no aging of plants caused by high temperature.

1. There is very little oxygen and nitrogen in the water, which cannot meet the needs of ordinary plants. After a lot of watering, the oxygen in the water is also partially absorbed by the microorganisms in the soil.

2. When there is no oxygen in the soil, the microorganisms in the soil will become very active, which can produce inorganic compounds such as hydrogen sulfide that are harmful to plants, and the rhizomes of plants will also breed pathogenic bacteria.

3. As a result, the rhizomes of the plant are rotten. The aquatic plant is adapted to life in the water, and its rhizome can absorb the oxygen in the water, even if there is little oxygen, it can also carry out normal exhalation stool inhalation, so the rhizome is not easy to rot.

The roots of the hydroponic plant rot, the roots are rinsed and pruned, soaked with carbendazim solution. The plants are re-cultivated in a container, and the water needs to be kept clear and changed every 2 days. Nutrient solution can be added to the container to make adequate nutrient supplementation.

Hydroponic plants need to get enough light to avoid migration.

Improper maintenance of hydroponic plants leads to root rot. The plant needs to be removed, the roots should be rinsed with clean water, and the damaged roots should be pruned properly. The roots of the plant are sterilized and disinfected with carbendazim solution, and the plant is re-soaked in water and placed in a transparent container for maintenance.

When hydroponic plants, it is necessary to ensure the clarity of water quality, change the water once every 2 days, effectively promote the absorption of plant roots, and wait for the root system of the plant to gradually stabilize. In winter, when the temperature drops, you can change the water once a week. When changing the water, it is also necessary to properly wash the roots of the plant to rinse off the mucus on the surface.

In hydroponic green plants, timely fertilization and sufficient nutrient supplementation can promote the growth of more vigorous. Nutrient solution is added to the water every week to promote the continuous growth of the plants. Spraying foliar fertilizer once a week can effectively increase the gloss of leaves, and can also play a role in resisting low temperatures in winter.

When hydroponic plants are planted, it is necessary to ensure sufficient light and maintain them in a dark place for a long time, and the plants will grow up. It is necessary to maintain the plants in a well-ventilated and bright place, with enough sunlight to allow the leaves to continuously photosynthesize, and sufficient sunlight in summer to provide proper shade protection to the plants.

The roots of hydroponic plants are rotten, you can use sterilized scissors to cut off the rotten root system to avoid further deterioration, and then put the roots of the plant into the diluted disinfectant water to soak for 10-20 minutes, and then plant the sterilized plants in the newly replaced water, after a period of time, the plant can grow roots again.

1. Prune the root system

The root system of hydroponic plants is rotten, it needs to be taken out of the original container immediately, and then all the rotten roots of the plant need to be cut off with sterilized scissors, if the stem of the plant is also rotten, it also needs to be cut off to avoid further deterioration of the situation, and the old roots can also be pruned off to promote the growth of new roots.

2. Disinfection and sterilization

The root system of hydroponic plants is rotten, and the pruned plant roots need to be soaked in diluted disinfectant water for 10-20 minutes to remove the germs on the roots of the plants and avoid the roots of hydroponic plants from continuing to rot, and potassium permanganate solution can also be sprayed into the original cultivation container for disinfection.

3. Replace the water

When growing plants with water, you need to pour two-thirds of the water into the sterilized cultivation container, either in sun-exposed tap water or purified water rich in minerals, and then replant the treated plants in the water and change the water every 3 days.

4. Maintenance management

When maintaining hydroponic plants, it is necessary to move them to a ventilated semi-shaded environment, and before the plant does not grow new roots, the nutrient solution can not be added to the water to avoid fertilizer damage to the plant, and after the plant adapts to the new environment, it can be applied 1-2 times of liquid fertilizer every other month to make the plant grow more vigorously.

1. What to do if the roots of water-fed plants rot.

1.Pruning rotten roots: If the roots of hydroponic plants are rotten, you need to take them out of the water in time, clean the roots of the plant with clean water, and then prepare a pair of clean scissors to cut off all the rotten, unhealthy roots.

2.Soaking disinfection: For pruned plant roots, carbendazim solution can be prepared if possible.

Dilute carbendazim with water until it is light milky white, then soak the plant roots in carbendazim solution and remove them after half an hour. 3.Rehydroponics:

The soaked plant roots can be air-dried in a cool and ventilated place, and the wounds on the roots can be air-dried before entering the hole before hydroponics. If you use the original container for hydroponics, you must wash the container and replace it with clean water.

2. Causes of root rot in aquaponics.

1.Water pollution: If the water is not changed for a long time, the water quality will be seriously polluted, and even stink, resulting in rot of plant roots.

For new hydroponic plants, change the water every two days, and after the plants have grown water roots, change the water. 2.Improper fertilization:

Poor growth of hydroponic plants is caused by insufficient nutrients in the water. Every time you change the water, you can drip nutrient solution into the water to replenish nutrients to the plants. But fertilization should not be excessive, thin fertilizer should be applied frequently, otherwise the plant will rot roots.

3.Excess water: For most plants in hydroponics, water is usually not enough to clear more than 2 3 of the root system.

Fugui bamboo can add water half the height of a hydroponic bottle. If too much water is added, the root system of the plant can rot easily.

Watering plants too much and too often, the causes of root rot are: soil water content is oversaturated for a long time, the air permeability of the soil becomes poor, the oxygen content is insufficient, the root respiration is blocked, the absorption function becomes poor, and the root system will die and rot when the lack of oxygen is serious, and the aboveground part will not get water and nutrients, and the whole plant will gradually die.

Potted plants should be watered according to different types and seasons, timely and appropriate watering, and the amount of watering should not be too large and too frequent. The soil moisture content suitable for most plants is about 60% of the maximum water holding capacity in the field (semi-dry and semi-wet).

Because on the one hand, plants absorb water and inorganic salts through the root system, and on the other hand, the root system also needs to respire, absorb oxygen, and carry out aerobic respiration. Therefore, the soil of terrestrial plants should alternate between dry and wet. In the case of prolonged soil moisture, there is a lack of oxygen in the soil, and the roots undergo anaerobic respiration, which produces ethanol.

Excess ethanol can attack cells. So it will cause root rot.

Watering the plant too much at one time, but draining it quickly, basically does not have much effect on the plant, at most it dissolves the fertilizer in the soil.

Constantly watering plants, causing long-term soil moisture, is fatal to plants.

Because plant roots need to respire in order to get energy, and their main respiration is supposed to be aerobic respiration.

However, too much water creates an anoxic environment around the root system, which hinders its aerobic respiration, and the root cells undergo anaerobic respiration.

The reaction process of anaerobic respiration in plant roots is: one molecule of organic matter (glucose) 2 molecules of alcohol + 2 molecules of carbon dioxide.

The excessive production of alcohol will erode the cells, change the permeability of the cell membrane, and dissolve certain lipids, so the roots will rot and blacken.
