1、 Rotten water treatment method

Excessive watering or excessive ponding in the basin will lead to rotten roots of plants. How to deal with more rotten roots in water can be divided into two cases: the roots are not completely rotten and the roots are rotten and can not be replanted, and then deal with them separately according to the degree of decay

< span style="font-size:12px;"> The rotten roots can be cut off and replanted the specific operations are as follows:

1. Remove the plant from the pot, find out the rotten roots, and cut off the rotten roots from the base with sterilized scissors

2. Disinfect the plant wound with 0.1% potassium permanganate solution, or apply clean plant ash to the wound, and then change the basin and soil for planting

3. When the pot is put on, the wound and the seriously damaged part of the root system shall be filled with clean wet sand around, and then new cultivation soil shall be added to promote the germination of new roots at the wound of the plant

4. When changing pots, the branches and leaves need to be trimmed in a large area

5. In the process of plant recovery and growth, ensure that the basin soil is breathable, do not apply fertilizer, and do not get wet, so as to prevent root rot from happening again

< span style="font-size:12px;"> The cuttings of branches and leaves can be used for reproduction the specific operations are as follows:

1. First take out the diseased plant, wash the root soil, and remove all the rotten parts with a sharp knife

2. Soak the stem base with 0.1% potassium permanganate solution for about 30 minutes. After taking it out, apply charcoal ash on the wound to prevent corrosion and infection, and then place it in a ventilated place to dry slightly

3. The replanted cultivation soil shall be fully mixed with fine river sand, garden soil and rice husk ash, and then poured with boiling water for disinfection. It shall be used after cooling, which is conducive to the regeneration of new roots after planting of diseased plants

4. When entering the basin, press the buried part by hand to make the stem base in close contact with the basin soil; After that, keep the breeding temperature within 20-25 degrees, and keep the basin soil slightly wet. If the basin soil is not dry, it will not be watered. New roots can generally be generated in about 40 days

2、 Reasons for rotten roots

1. Excessive watering: < span style = "font size: 12px;" > Excessive watering is the main cause of plant root rot. Some drought tolerant plants are most afraid of ponding. Ponding causes hypoxia in their roots and rotten roots. In addition, in winter, some plants are in dormancy and transpiration is slow. If the watering amount is not controlled in time, it is also easy to accumulate water and Rett roots

2. Poor water quality: < span style = "font size: 12px;" > Hydroponic plants have a high demand for water. If it has rotten roots, it is mostly due to the poor water quality and more microorganisms in the bottle, resulting in the infection and decay of plant root pathogens. Moreover, microorganisms will compete with plants for oxygen, causing plant roots to decay due to hypoxia

3. Bacterial infection: < span style = "font size: 12px;" > Too many microorganisms in the basin soil will also cause plant root rot. So try to use clean water and fertilizer

4. Poor soil permeability: < span style = "font size: 12px;" > The soil has poor drainage and poor air permeability, which is easy to harden the soil. Once the soil hardens, it will make the root of the plant breathe unobstructed, hinder the growth, and cause the root of the plant to rot
