The cause and control of rotten roots of Cymbidium, and know the prevention and control methods of edible fungus diseases.

Spring is the season of luxuriant growth of Magnolia, but it is easy to emerge rotting roots because of improper management of water and fertilizer, which is mainly caused by the following reasons.

First, the water is overwatered.

No matter it is a small seedling or a large seedling, the water should not be overpoured. If the water is big, the temperature is high, and no matter how bad the ventilation is, the gentleman orchid will surely rot its roots.

Second, Tu Taisheng

Whether using rotten leaf soil or horse dung soil, the preparation of nutrient soil with peat soil must be fully fermented. If some raw soil is put into the basin, under the condition of high temperature, these raw soil will produce high temperature after fermentation and burn the fleshy root.

Third, the fertilizer is not fermented well.

Bean cakes are given to magnolia, sesame seeds and fishy water must be fully fermented. If some raw fertilizer is applied to the basin soil, the fleshy roots will be burnt at high temperature.

Fourth, excessive fertilizer application leads to rotting roots.

In particular, we can not apply too much chemical fertilizer, because the irritation of chemical fertilizer is too great, although it can promote the rapid growth of leaves in a short time, but excessive fertilization can cause too much damage to fleshy roots, which is easy to cause atrophy and rotting roots.

Fifth, use porcelain pots and plastic pots with poor permeability to raise gentleman orchids.

Because of the poor air permeability, the rhizome will be rotten.

Sixth, the temperature is too high.

Especially in the seedling stage, the bottom temperature can be maintained at 22 ℃, but some people put the seedling pots and boxes on the hot Kang or radiator for a long time, resulting in quickly covering the roots of the seedlings.

According to the above situation, if we pay attention to prevention, the rotting root scene of gentleman orchid can be avoided.

But in case you don't have a town, you don't have to worry about finding that your orchid has rotten roots, just knock the plant out of the basin, cut off the rotten roots, coat the cut with charcoal or soot, and then change the soil and put it on the pot again. If the fleshy roots have all rotted away, it does not matter, you can pinch off all the rotten roots, then wash the roots with clean water, and then put them in the coarse sand to promote the roots, and cut off part of the leaves.
