A brief introduction to the rotten roots of Gentleman

The injury of the root of the orchid, the gradual thinning and discoloration of the leaves is a sign, and the yellowing of the leaf tip is the signal. Next, I will introduce to you how to do the rotten roots of the orchid.

The reason for the rotting Root of Gentleman

The main results are as follows: 1. High temperature, high humidity and poor ventilation make the fleshy root of the plant rotten easily.

2. The water is large, the water content of the nutritious soil is large, the air permeability is poor, and the root is soaked in water for a long time, which leads to root discoloration and decay.

3. Hypertrophy, the fertilizer in the nutritious soil is not fully fermented, resulting in root rotting caused by heating and burning, improper fertilization during the growing period, excessive amount of fertilizer, resulting in fertilizer contact with the root, resulting in root burning, affecting the root absorption capacity, root tissue is destroyed and rotten root, we should pay attention to the diligent application of thin fertilizer.

4. when the root is injured, when changing the basin or dividing the basin, the rotten fleshy root must be completely eliminated, then coated with charcoal or fine furnace ash to dry, and then cultivated in the basin to prevent the injured root from coming into direct contact with nutritious soil bacteria and rot.

5, the air permeability is not good, the use of porcelain pots, plastic pots and so on lead to the basin soil air permeability, water permeability is not good and rotten roots.

6. The soil quality is not good. Bacterial ☆ prevents ☆ disease from eroding the fleshy root, resulting in ulceration.

The solution to the rotting Root of Gentleman

Improve the quality of nutritious soil

The permeability of the nutritious soil is not good; the soil is overripe or overgrown, and the tussah leaves used before preparing the nutritious soil cannot be overrotted or overgrown. If the unripe tussah leaves are used to prepare the nutritious soil, heat will be generated after fermentation in the basin.

Adjust the amount of fertilizer and water the right amount.

The magnolia should not fertilize too much, otherwise it will generate heat and cause root system to burn and rot. Watering should also be appropriate, too much will make the nutrient soil water content is too large, poor permeability, root breathing difficulties, resulting in rotting roots. Be careful not to water the heart of the orchid.

Propagation with bacteria in nutritious soil

High-temperature and humid environment to prevent bacterial reproduction, bacterial infection, in this environment, a large number of bacteria multiply, directly invade the root system and cause rotting root. Therefore, in the summer and autumn high temperature season, excessive fertilization and watering, it is easy to appear root rot. It is necessary to strengthen cooling and ventilation, control man-made mechanical injuries in high temperature season, spray drugs in time to prevent insect bites, and reduce the reproduction and spread of germs.

How to prevent the rotting Root of Cymbidium

The planting process of Cymbidium should be observed frequently, and if it is found that there is a rotten root phenomenon, it should be treated immediately. Take out the plant, remove the rotten root, rinse the root with 1% potassium permanganate water for disinfection, or apply some charcoal powder to the affected area and sun the root in the greenhouse for about 30 minutes. If the rotten root is more than 50% or all rotten, use the above method to treat and then use river sand to promote the root. The root-promoting temperature should be higher than the normal temperature, which is generally controlled at about 22-30 ℃, so that new roots will grow after about 2 months, and then transplanted to the nutrient soil basin.

The above is the introduction of the rotten root of the gentleman orchid. I hope you can like it.
