For most people, orchids are noble and splendid, and the most troublesome in day-to-day management is the abnormal conditions (such as delicate roots, thin or decayed necrosis, dark spots, brown spots, rust spots, leaves Burning, dehydration of dried leaves, yellowing of whole orchids, sprouting of sprouts, etc.).
What is the reason for the blue plant's abnormality to be distinguished? The environmental factors, the nutritional factors, or the diseases and pests cause the cause to be diagnosed before the symptoms can be treated so that your orchid can proudly show to people. If it is not possible to blindly deal with the illness of the orchid plant, despite the good intentions and unhelpful remedy, this disease has not been alleviated, and other illnesses have emerged.
One, root tip rot
1. Apical prolonged exposure to cultured dry water, and poor ventilation, causing bacterial proliferation caused by ulceration.
2. When the plant was shaken, the blue root strained the root tip, and the oil, smoke, and sweat were caused by injury to the root tip. Prevention: Do not touch the root tip when changing pots and planting plants. Careful drainage and ventilation after planting can prevent it.
Second, rot is black and rotten
1. The root tip is not healed and watered, resulting in the proliferation of bacteria. The prevention method is the same as the root tip treatment method.
2. The roots are hollow and free from meat. They are eaten by bacteria and eaten by insects. They are too wet or too dry to cause black nets. Prevention: After disinfection, sterilization after sterilization, the wind blows until it is half dry and then it can be controlled.
Third, the growing point is dry
1. The growth point is exposed to the soil and exposed to the sun.
2. The bulbs grow too deep and do not ventilate, causing the growing point to rot. Prevention: Prevent the occurrence of job situation, it can play a preventive role.
Fourth, buds are easy to rust spots
1. The rotten buds are when the buds open leaves and the buds are filled with water, which is caused by the sun.
2. If the temperature is high, the orchid strain waters when it does not return to normal temperature, causing the buds to rust, which is very serious.
V. Shoot buds dry
1. The dried leaves are dry and the weather is hot and poorly ventilated. Watering leaves the stumbling leaves warm.
2. If the temporal lobe is black and rotten, it will be caused by bacterial infection if the culture soil is too wet or if the culture soil is not replaced for too long.
Sixth, fake bulbous shrinkage
1. The fake ball type gradually shrinks. After several weeks or months, the leaves are yellow-green. Because the watering is insufficient, the bark is easily planted or caused by long-term low temperature.
2. Difficulties caused by the burning of coke into a patch, due to the sun is too strong, causing sunburn disease, Deng shady should be given.
Seven, leaves turn yellow or red
1. The old leaves turn yellow and fall off, which is a normal aging phenomenon.
2. The leaves turn yellow and green, and his parts are normal, due to too strong light.
3. The leaves become purple and red. The new leaves are more obvious due to ultraviolet rays, nitrogen deficiency or low temperature damage.
4. The apex of the new leaves seems to be scorched. In severe cases, the base will die. The root in the pot will die, but it will not be infected. Because too much fertilizer is used, there will be too much accumulation of nutrients in the plant material, and too much nutrients should be washed away.
5. The young leaves are initially hooked and then die inward from the tips of the leaves and leaves, resulting in calcium deficiency in the plants.
6. The base of the young leaves is light green, withered from the base of the leaves, and the leaves are twisted, resulting in plant lack of boron.
8. When the flower buds turn yellow or gargle does not spread out
1. The calyx turns yellow and then brown, due to too much wet or loved ethylene contamination.
2. The adhesion of flowers is not easy to spread and the humidity is too low.
3. Metamorphic calyx, caused by genetic factors or unknown physiological factors.
Nine, buds do not grow
1. Flower buds do not grow due to genetic factors or nighttime temperatures are too high.
2. The flower buds are yellow and red-orange and soon fall off, which is caused by ethylene contamination.
3. The solidification of the liquid densely binds the front end of the flower bud and does not properly spread. Because the temperature is too low, it will occur in the Phalaenopsis, Catliarin, and Wanslan.
Ten, flowers are immature and wither
1. The base of the labrum becomes red and suffers cold damage.
2. The red tongue is abnormally red and withered, because the pollen is detached or has been fertilized.
3. The outer edge of the lip changes and blights, and some of the flowers are deformed due to exposure to light for too long.
4. When it is immature, it fades, and at the same time, the ovary becomes yellow or pink and is contaminated by ethylene.
Eleven, insects, ants cause diseases
1. As long as the ant is killed due to pests and ants, continue to prevent it.
2. The leaves, buds, growth points, bulbs, root rot, etc. are all caused by the hot weather, high temperature, careless watering, and poor ventilation due to potholes.
Twelve, fertilizer damage, medicine injury
1. The fat injury is excessive fertilizer, so that the ability to resist half-plant growth resists wilting and wither.
2. In order to increase the number of shoots, fertilize them by any means. In one to two years, the amount of growth is considerable. However, the leaves of the old plants are yellow and the roots are rot. In severe cases, they grow into one bud and wither a bud.
3. Due to excessive fertilization and excessive accumulation, the orchid strain cannot digest the toxin and pass it on to a small bud. This results in a “Byras†disease after it grows. This is the last step in increasing the number of orchids and not selecting many segments. result.
