The pathogenesis of soft rot in Cymbidium
Bacterial infection, through the insects bite the leaves, into the leaves of Cymbidium. The initial symptom is that two leaves at the bottom turn yellow, and if you continue to observe, you will find that there are black watery spots at the base of the plant. , expand upward until the infected leaves, so that the base and roots of the plant completely rot, so that the plant can not support and fall down.
The cause of soft rot in Cymbidium
1. The air is too humid, poorly ventilated and overshadowed.
two。 There are often dust and organic matter in the leaf sheath, which provide conditions for germs to invade plants. In areas with many rainy seasons, especially in the southern plum rain season, Cymbidium is particularly prone to this disease.
The organic nutrient solution of sugarcane stalk fermentation is rich in nitrogen, phosphorus and potassium, which promotes the development of Cymbidium roots, strong plants, bright green leaves, arrows, flowering, prolonging florescence and improving plant resistance to diseases and insect pests.
What if the gentleman orchid gets soft rot?
Since it is a bacterial infection, of course it has to be sterilized. From basin soil, roots to leaves should be sterilized and disinfected. Magnolia cultivation soil generally uses slag, charcoal, and rotten leaf soil, either replace it, or bake it in a microwave oven, then dilute it with carbendazim 1000 times and spray it to dry.
If the disease is found earlier, it can also be saved, turn the basin directly and check the root system, and the rotten roots or leaves are all trimmed clean, then soak with 1000 times diluted potassium potassium for 2 hours, put it in a cool place to dry, and then replant it.
If you want the orchid to be strong in resistance to diseases and insect pests, you must first ensure adequate nutrition, promote plant health, root system development, and stress resistance. The organic nutrient solution fermented by sugarcane molasses has rich and balanced elements, and bacteria are added, which can decompose the harmful components in the soil and improve the soil environment.
In peacetime maintenance, we must pay attention to put the magnolia in a well-ventilated place where the light can reach about 6 hours a day, be careful not to expose yourself to the hot sun, watering must be controlled, and must not cause stagnant water in the basin soil. You can use the double-basin method to spray the basin soil and fill it with water at the bottom of the basin.
Gentleman orchid clip arrow, the main reason is that potash fertilizer is not enough, if self-made fertilizer, use potassium dihydrogen phosphate once a month, dilute 1000 times. You don't have to go to so much trouble to use organic nutrient solution.
Symptoms of soft rot of Cymbidium
Gentleman orchid, also known as Lycoris radiata, Lycoris macrophylla, is a more common flowering plant, but also a variety that many flower friends like very much. But in the hot summer, the gentleman orchid is very easy to get sick, soft rot is more likely to occur in the summer.
Gentleman orchid
Soft rot mainly harms pseudobulbs and leaves of Cymbidium. At the initial stage of the disease, the leaves were damaged, the heart leaves and the base of the heart leaves showed dark green waterlogging-like disease spots, the diseased leaves rotted and became soft and sagging, spread to the root system to make it mushy, the center of the leaves fell off, and the whole plant died. The pathogen of soft rot is Euclid bacilli, the lesion begins from the base of the plant, and then the leaves begin to rot, and the leaves and stems rot into paste and have a bad smell. After 2 to 3 days, the disease part of the leaves shows a sticky and soft rot-like "stem rot" lesion. The outer leaves were good, the heart leaves were rotten, the leaves and stem bases were good, the leaves rotted locally, and the whole leaves rotted and spread gradually within 12 hours, and the diseased part showed water-immersed "rotten leaf" lesions, and the rotting roots and leaves wilted. The root system showed a purulent "rotting root" lesion. The pathogen of soft rot is mainly overwintering in the residue of diseased plant and soil. The disease is easy to occur in summer with wet rain, high temperature, poor ventilation and application of a large amount of unrotten fertilizer.
Do a good job in the prevention and control of soft rot of Cymbidium

Prevention and control measures of soft rot of Cymbidium:
1. Keep good ventilation and light transmittance in the field, and remove the old and withered leaves at the base of Cymbidium in time, so as to effectively reduce the breeding of bacteria. Adequate supply of water and fertilizer, balanced application of nitrogen, phosphorus and potassium fertilizer, foliar spraying of flower Zhuangtiling, in order to improve the ability of water and fertilizer absorption, promote plant growth and disease resistance.
2. When diseased plants are found, they should be isolated from healthy flowers in time so as not to cause a large number of orchids to be infected with soft rot. Remove the nutrient soil around the infected plant, remove the rotten parts and spray the tree protection general to keep the plant in sufficient light in order to effectively control the damage of soft rot.
