How to deal with the rotting Roots of hydroponic plants

People who like to raise green plants know that most hydroponic plants are lazy plants, which are generally easier to raise than soil plants, but if you ignore it too much, or if you do not handle it properly, it will also cause rotten roots. If you see that the roots of the plants have turned yellow, black or the water stinks, they are basically rotten roots, what should you do at this time? Today, the editor will tell you about the cause analysis and solutions of rotten roots of hydroponic plants, hoping to help you better understand their own hydroponic plants.

1. analysis of the causes of rotten roots of hydroponic plants.

The main results are as follows: 1. The content of dissolved oxygen in the nutrient solution of hydroponic culture is low, which results in the death of plant roots due to hypoxia. This situation is more obvious in summer. At this point, you can increase the number of cycles and time of the pump. To increase the content of dissolved oxygen in the nutrient solution.

2. The nutrient solution flooded all the roots and even the rhizomes. This is also a place that people are easy to overlook in family soilless cultivation. Generally the best cultivation is to leave half of the root in the nutrient solution and the other half to be exposed to the air. This can greatly increase the oxygen supply of plant roots and effectively reduce the occurrence of root rot.

3. Check the quality of nutrient solution. Water quality is caused by residual plant debris or residual matrix, nutrient solution precipitation, etc., if the water quality is found to be relatively turbid or odorous, the water should be changed in time to ensure the normal growth of plants.

4. In the process of planting, the supply of nutrient solution can be reduced appropriately, because the water quality is different in different areas. In areas where the water quality is hard, precipitation is easy to occur when configuring nutrient solution. If the water quality in your area is hard, you can choose to use the normal dose of 1max 2 or 1max 4 to configure the nutrient solution.

5. The change of pH of water is too large. In general, a mature formula adds or changes the nutrient solution within a specified period of time. PH changes will not change much. However, it is best for users to prepare a PH test strip. It can be monitored regularly to make sure that you have a clear idea. The adaptation range of most plants is between PH5---7. Except for special plants, of course.

6. Temperature. The high temperature here on the one hand refers to the temperature of the nutrient solution. Because the high temperature will cause the aging of the plant roots. Therefore, the maximum temperature of the nutrient solution should not be maintained above 30 degrees for a long time. This is a big factor in summer. The general solution is to avoid direct sunlight in the storage tank. Add sunshade if necessary.

2. Treatment of rotting roots of hydroponic plants.

1. After the rotten root is found, the rotten part should be cut off as soon as possible, and then put into carbendazim or methyl topiramate (broad-spectrum, high-efficiency and low-toxic internal absorption fungicide, which has the functions of internal absorption, prevention, protection and treatment. It is sold in the flower market, a few yuan a pack) for disinfection, you can put the fungicide into the water to soak the roots for one day, and then replace the new tap water the next day.

2. after the roots of the plants are rotten, they can only be raised with clean water, and the nutrient solution will be added after the plants adapt to the environment and grow new roots.

How to deal with the rotting Roots of hydroponic plants

China Garden Network, Aug. 4 News: people who like to raise green plants all know that most hydroponic plants are lazy plants, which are generally easier to raise than native plants, but if you ignore it too much, or if you do not handle it properly, it will also cause rotten roots. if you see that the roots of plants have turned yellow, black or the water smells bad, what should you do at this time? Today, the editor will tell you about the cause analysis and solutions of rotten roots of hydroponic plants, hoping to help you better understand their own hydroponic plants.

Causes of Root Rot of hydroponic plants and corresponding measures

Hydroponic culture is a new method of plant cultivation, which is also a method of soilless cultivation by naturally spreading the plant roots in the nutrient solution and using the nutrient solution to provide the substances and elements needed by the plant. The plant cultivated by hydroponic culture has a clean and tidy appearance, has a high style and ornamental, is often used for indoor decoration and has been praised by the majority of consumers.

However, due to the imperfect technology of hydroponic culture, hydroponic plants will encounter a series of problems such as lack of nutrition and hypoxia in the process of growth, resulting in malnutrition, yellowing leaves, poor quality and even rotting roots. Especially now that it is summer, it is a season in which hydroponic plants often have rotten roots, so we should understand the causes of rotten roots and master the corresponding countermeasures.

There are many reasons for the rotten roots of hydroponic plants. first of all, due to the increase of temperature, the concentration of some hormones in the plant changes dramatically, such as the decrease of cytokinin and auxin, while the content of abscisic acid increases sharply, which leads to root rot. Secondly, due to the increase of temperature, the solubility of oxygen in water decreases greatly, coupled with the enhancement of the reproductive ability of microorganisms in water, more oxygen is consumed, and the concentration of oxygen in water is lower than the critical value needed for plant breathing. therefore, plants will have the phenomenon of anoxic rotting roots. In addition, due to the increase of temperature, the enzyme activity in the plant root decreased greatly, which passivated a series of reactions in the plant, thus accelerating the aging of the root and causing the plant root to rot. In addition, high temperature is conducive to the growth of microorganisms, water is easy to breed a large number of bacteria, causing damage to the root system, resulting in rotting root phenomenon.

In view of the above reasons, in order to solve the root rot phenomenon of hydroponic plants, it is necessary to control the water temperature in the range of 18-28 degrees Celsius, which is more suitable for plant growth. In the absence of cooling measures, the container of hydroponic plants can be increased or placed in a cool place to cool down. In addition, oxygen cycle can be accelerated and oxygen exposure measures can be taken to solve this problem. For bacteria in water, a certain concentration of hydrogen peroxide can be added to the solution, or sterilized by ozone, ultraviolet radiation and other methods, which is an effective way to prevent bacteria from rotting roots.

In general, in order to prevent the occurrence of rotting roots, it is necessary to ensure that there is an adequate supply of oxygen in the nutrient solution and maintain the appropriate temperature for plant growth. Having mastered the above methods, I believe everyone will be able to take good care of the hydroponic plants at home and maintain their good growth. In this way, the cultivated hydroponic plants can not only decorate the indoor style, but also purify the air, which is conducive to a healthy home life.
