Integrated control of tomato diseases
1. Change seedling bed to new soil, or treat bed soil with the green sterilizer No. 8 soil disinfectant drug (see the prevention and cure of vegetable seedling disease in the disinfection method), or adopt the ground heat nursery and plastic seedling nursery to reduce the root damage and shorten the nursery period (viruses Disease, Fusarium wilt, Canker disease, Bacterial wilt.
2. The disease-free strains are seeded, or the seeds are soaked in hot scald or seeded with chemicals such as Greenhenge No.1.
3. The implementation of non-solanum crop rotation for more than 3 years.
4. Protect tomatoes in the early spring to increase the temperature and temperature of the land. After the flowering results, strengthen the ventilation, reduce the humidity, and reduce the condensation (grey mildew, late blight, blight, ulcer disease, and leaf mold).
5. Autumn tomato nursery is carried out in rain-proof, insect-proof and shading protected areas (virus disease, late blight, virus disease, etc.).
6. Autumn greenhouse tomato to increase the amount of ventilation, reduce the temperature and humidity (leaf mold, early blight, blight).
7. Focus on the prevention and treatment of drugs In the prevention and early onset of the disease, it is possible to spray Botrytis cinerea and leaf mold with 800 to 1000 times of green hengheng No. For diseases such as stem blight, leaf, and fruit diseases such as late blight, it can be used to spray 800 to 1000 times of water on Green II, which can cure a variety of diseases. For bacterial wilt, soft rot. Virus disease and other available Green Hunter No. 6 (sterilization king) 1000 ~ 1500 times plus hi every spring, it is best to use Nornal grams of 8 grams of water 30 kg plus green wind 95 '(nucleotide) 30 Jin spray control Better results.
What is Fractional Co2 Laser
Fractional CO2 Laser generate beams of coherent light that are absorbed by the body's tissue as energy. The energy is delivered through a narrow range of wavelengths, and in the target area, the energy
causes temperature elevation which results in tissue evaporation or ablation. Fractional CO2 Laser effectively treat a broad range of skin conditions by removing all or part of the skin.
The body's natural healing processes then replace the damaged skin with new and healthy tissue.
How Does A Fractional CO2 Laser Work?
Fractional CO2 Laser produce light at a 10,600nm wavelength, which is absorbed by water in the tissue. The laser energy heats up the water until it reaches a boiling point causing the evaporation of the affected tissue. Some heat is absorbed by tissue adjacent to the ablated target area, causing tissue coagulation which induces hemostasis (the cessation of bleeding) as well as thermal stimulation of deep skin layers, which induces fibroblast stimulation and neocollagenesis (the formation of new collagen).
The laser beam can also be transmitted through a scanner which is a device used to further control the delivery of energy. The scanner regulates the configuration of energy delivered onto the skin, which can range from covering the entire treatment area or just a fraction of it (leaving the areas in between untreated); (also referred to as fractional ablation). The overall effect of ablation and coagulation, either full or fractional, is the removal of skin and the stimulation of the body to replace it with newer, younger skin.
