Hydroponics has got rid of the infestation of soil pests and diseases, but it does not grow in a vacuum environment after strict disinfection, and it will still be invaded by environmental pests and diseases. Fungi, bacteria and viruses in the air can still infect the stems and leaves of hydroponic flowers, causing them to be affected to varying degrees. Aphids and scale insects can float into the room with the wind, and land on the hydroponic flowers to suck the juice. Moths lay eggs on flowers, hatch into larvae, and also eat the young leaves and shoot tips of flowers. De-washing roots are changed to static hydroponic flowers, which also carry fungi, bacteria, viruses, eggs, larvae, etc. If not carefully checked, it will leave hidden dangers.
Static hydroponic flowers are not suitable for chemical pests and pesticides, and cannot be sterilized with large doses of fungicides, because of the special nature of their environment. This should be based on prevention of pests and diseases that may occur in hydroponic flowers. When choosing flower hydroponics, try to select flowers that are robust, growy, and free from pests and diseases. Pests are found during the maintenance process and can be manually captured or rinsed with tap water. There are not many invasive diseases in hydroponic flowers. Only a few leaves have brown lesions, dry necrosis, or irregular round wet lesions, which are formed by fungal or bacterial infection. The diseased leaves are removed and burned, and should not be spread. Prevention of non-invasive diseases. Non-invasive diseases are not caused by pathogen infestation, it is caused by an unsuitable environment. Summer sultry hot weather, cold winter, dry climate, hot sun burns, unpleasant air, excessive shade, excessive concentration of nutrient solution, or inability to absorb evenly, may cause the still hydroponic flower tip to be scorched, lower part The leaves are yellow and fall off. The temperature in summer is too high, and the dissolved oxygen in the liquid drops sharply, which is prone to root rot, which is a common symptom of static hydroponics. Find out the corresponding causes for the above different symptoms, correct them, improve the maintenance environment, and avoid the occurrence of non-invasive diseases.
How to maintain the static hydroponic flower of the knot and rotten root? Due to improper management, or roots of oxygen-deficient roots, or infection by fungi, bacteria, and viruses, leaf spot disease occurs in hydroponic flowers, and the leaves turn yellow and fall off a lot, causing the lower end to be disjointed and losing ornamental value. Hydroponics flowers with disjointed and rotten roots can be treated by plant regeneration method. The upper branches are cut at 3 cm from the lower end of the stem section and inserted in clear water. After a period of conservation management, new roots can be grown. Become an independent plant. Branches that are dislocated at the lower end, as long as they do not rot, can also sprout new shoots in the stem section. At this time, they can be cultivated with nutrient solution. This method can be used for rich bamboo, green radish, colorful banana, and fruit.
