Tomato is a kind of warm vegetable. The suitable temperature for daytime growth is generally about 25 degrees. At night, it is about 16 degrees. Except for germination, emergence and slow seedling period, higher temperature and humidity are required. High humidity. Seed treatment Soak the seeds in warm water, that is, soak the seeds in water for 1 to 2 hours, then remove the seeds and put them into hot water at 55 degrees Celsius, keep the water temperature evenly soaked for 15 minutes, and then continue soaking for 3 to 4 hours. When soaking in warm water, it is usually one seed and two parts of water; it should be stirred constantly and rapidly to make the seeds evenly heated to prevent scalding the seeds. The third is to continuously heat the water and maintain the temperature of 50 degrees. It can prevent the occurrence of diseases such as leaf mold, ulcer disease and early blight. 2. Germination and sowing According to planting season, climatic conditions, cultivation methods, nursery facilities and other factors to consider the appropriate planting period. For example, spring open field cultivation, the Beijing area usually seeded seedlings from mid-February to early March. When germination is carried out, usually untreated seeds should be soaked in warm water for 6-8 hours to fully expand the seeds, and then placed at 25-28 degrees Celsius for 2 to 3 days. Seeds soaked with chemicals can be directly germinated by simply rinsing the seeds with water. In the process of germination, it is necessary to provide suitable temperature, moisture and air. For this reason, the seeds should be inspected and turned frequently, so that the seeds are in a loose state, and they need to be washed with water once or twice a day to renew the air and maintain the humidity. It is best to use an incubator for germination. After germination of the seeds, the seedlings are quick and tidy after sowing, which is conducive to the cultivation of robust seedlings. Seeding method. There are usually broadcasts, broadcasts and on-demand broadcasts. Immediately after sowing, cover the soil and cover the soil with fine soil. The thickness of the covering soil is about 0.8 to 1.0 cm, and the thickness should be the same. After sowing, 8 g of 50% carbendazim wettable powder per square meter of seedbed is mixed with fine soil and evenly spread on the bed surface to prevent seedling collapse. The mulch film is also covered on the bed surface of the winter and spring nursery beds. Shading nets or straw should be covered on the bed surface of the summer and autumn nursery beds, and the cover should be removed when 70% of the seedlings are topped. 3. Seedling management In general, the temperature of the nursery bed is higher, the heat preservation condition is good, and the seed is germinated first. It can be emerged 2 to 3 days after sowing. The management of the seedling stage is mainly the control of temperature and illumination. Seedbed management from sowing to emergence, this period refers to the full expansion period of sowing to two cotyledons. In the spring season, the seedling period of tomato cultivation is arranged in the cold season, and the bed temperature must be controlled at 25 to 28 degrees Celsius and 15 to 18 degrees Celsius. When using cold or hot bed seedlings, solar energy should be fully utilized during this period to increase the bed temperature and use the cover to maintain a high bed temperature. Before the emergence of the seedlings, the film is generally not uncovered, and the window is opened. When the young shoots start to emerge from the top soil, if the overburden is too thin and the top shell phenomenon is found, the soil should be covered once more immediately. 4. Growth period management Grasp the management of growth period, including cultivating and weeding, water storage and protection, tying vines, pruning, removing old leaves, ventilating and lightening, strengthening pest control, and strengthening temperature management. Among them, the diseases of tomatoes mainly include viral diseases, bacterial wilt, early blight, late blight, etc.; insect pests mainly include cotton bollworms and aphids. The disease of tomatoes can be prevented and refractory, and should be based on prevention. The prevention and treatment methods of viral diseases include: selection of disease-resistant varieties, seed disinfection, planting of alfalfa, control of aphids, and early planting. Temperature management is to increase the ventilation of the shed during the day, so that the temperature inside the shed is kept at around 25 °C. The night temperature is maintained between 10 and 13 °C. When the wind starts to be released, the air outlet should be small to large, from small to large, and the air outlet will gradually become smaller or closed after the temperature drops in the afternoon. Do a good job in fertilizer management. The growth period of tomatoes generally does not require watering in the summer and autumn rainy seasons, but when the 2 to 3 ear fruits are ripe, they should be properly watered. According to the growth of tomato plants, timely topdressing to promote fruit development, preserve flowers and preserve fruit. Conditional can be followed by bean cake, cottonseed cake and other cake fertilizer. 5. Fruit picking Picking fruit at the right time, the tomatoes ripen with green ripe, discolored, mature, and mature. Storage and preservation can be harvested during the green ripening period. Transport for sale can be picked during the color change period (1/3 of the fruit turns red). On-site sale or self-feeding should be picked when the ripening period is more than 1/3 of the fruit turns red. It should be lightly picked and harvested when harvesting. It is best not to bring fruit stalks when picking up, in case the fruits are stabbed in each other during shipment. Before the first frost, if there is still a green fruit that cannot be cooked, it should be stored in the greenhouse after harvesting, and then listed after the fruit becomes ripe, which not only prolongs the supply period, but also increases the economic benefits. In the post-fruit ripening period, it is not suitable to use hormones to stimulate fruit coloring. After being selected and packaged for sale, it has the advantages of reducing production cost, improving fruit quality, and ensuring consumer safety.

Red light therapy (RLT) is a treatment that may aid in the healing of skin, muscle tissue, and other body components. It exposes you to red or near-infrared light at modest intensities. Infrared light is a sort of energy that your eyes cannot see but which your body perceives as heat. Red light is comparable to infrared light, however it is visible.
Hair loss is a common occurrence. In one research, men and women with androgenetic alopecia (a hereditary condition that causes hair loss) gained thicker hair after using an at-home RLT device for 24 weeks. The outcomes were not the same for those who utilized a bogus RLT gadget in the trial.

Low-level laser treatment (LLLT), low-power laser therapy (LPLT), and photobiomodulation are all terms for red light therapy (PBM).
What Is Red Light Therapy and How Does It Work?
Red light treatment involves exposing your skin to a red-light bulb, gadget, or laser. Mitochondria, also known as the "power generators" of your cells, absorb it and use it to produce additional energy. This, according to some scientists, helps cells repair themselves and grow healthier. This promotes skin and muscular tissue repair.
The skin is not injured or burned by red light treatment since it employs very low amounts of heat. It is not the same sort of light used in tanning salons, and it does not expose your skin to UV rays that are harmful to your skin.
What Is It Used For?
Red light treatment has been studied for a long time. However, there aren't many research on it, and no one knows if it's better than other sorts of healing treatments. The use of red light therapy may be beneficial in the following situations:
Dementia. People with dementia who received near-infrared light treatment on their heads and via their nostrils on a daily basis for 12 weeks had improved memory, slept better, and were less irritable.
Pain in the teeth. People with temporomandibular dysfunction syndrome (TMD) experienced decreased discomfort, clicking, and jaw soreness after receiving red light treatment, according to another small study.
Osteoarthritis. According to one research, red and infrared light treatment reduced osteoarthritis-related pain by more than half.
Tendinitis. RLT appears to reduce inflammation and discomfort in persons with Achilles tendonitis, according to a small trial of seven participants.
Wrinkles and other symptoms of aging and damage to the skin. RLT has been shown in studies to aid with wrinkles and skin smoothing. RLT can also assist with acne scars, burns, and sun damage indications.
Even though experts aren't clear how or why red light treatment works, it's usually thought to be safe. There are also no hard and fast guidelines on how much light to use. Too much light can harm skin tissue, while too little can make it less effective.
What Is Red Light Therapy and Where Can You Get It?
At most cases, it's done in a doctor's office. Some salons and dentistry clinics, however, do it as well. You may also purchase a red light treatment gadget on your own. Side effects and injuries are more likely to occur with salon and at-home treatments. If you're considering red light treatment, see your doctor first.
