At present, most corn fields are from the big bell mouth stage to the tasseling and silking stage. Strengthening the field management in the middle and late stages is of great significance for ensuring the full grain weight and achieving high yields. In this issue, the farmer has compiled the following corn field management measures for farmers’ reference:
Pay close attention to scientific top dressing, strengthen the plant and delay the decline
At present, summer maize is commonly planted with fertilizer, and there is more precipitation in the early stage, and the plant grows rapidly. The soil nutrients, especially nitrogen, are leached seriously, which is easy to cause defertilization in the later stage. The big bell-mouth period is the key period for corn to require fertilizer. For normal plots, 12-15 kilograms of urea and 10-15 kilograms of potassium sulfate are applied per acre. The high-yield plots should be appropriately increased. If conditions permit, drones can be used to spray a mixture of potassium dihydrogen phosphate, urea, etc. on the leaf surface during the filling period to delay leaf senescence, promote the accumulation of photosynthetic products, and increase grain weight.
"One prevention and double reduction" to prevent pests
Since corn was planted, there has been more precipitation, high humidity and high temperature in the field, and the probability of pests and diseases in the later period increases. At present, it is the critical period for "one prevention and double reduction", mixing sterilization and insecticides, and using large-scale pesticide application equipment or flying control for large-scale prevention and control, one-time pesticide application and treatment of multiple diseases and insect pests, and reduce ear insects in the middle and late stages of corn Occurrence base, reduce disease prevalence, and reduce yield loss caused by disease and insect pests.
Do a good job after the rain to reduce losses due to disasters
Pay close attention to changes in the weather, clear the ditches in time, and drain the field water as soon as possible when waterlogging occurs. If the plant falls and can stand up again due to strong wind, bamboo poles can be used to knock off the accumulated water of the plant to promote the restoration of growth; if the yield is seriously affected, it should be removed or silaged in time.
Improve pollination quality to ensure large ears and more grains
High temperature and dryness and rainy weather will affect the normal pollination of corn. The high-yield plots have large populations and high overlap of leaves. Artificial emasculation and low-altitude drone flight assisted pollination can be carried out to promote uniform pollen dispersion to increase the seed setting rate and ensure that the ears are large and more grains.
Mechanical harvesting at the right time to maximize production potential
At present, most varieties have a long growth period and cannot mature normally at harvest. Harvesting at the right time can ensure the filling time, guarantee the accumulation of dry matter, and give full play to the high yield potential of the variety. It is recommended that general plots be harvested at the end of September and early October, and high-yield plots should be harvested around October 10. At the same time, when the water content of corn kernels drops to 26%, the corn grains can be harvested directly.
Learn to guide, improve the quality of straw utilization
For plots where straws are returned to the field, it is necessary to strengthen the training of the operators to ensure that the corn stalks are chopped and thrown evenly. When deep turning, urea and composting agents should be added to speed up the decomposition of the straw; areas with conditions can carry out corn yellow storage and biomass Can be used comprehensively.

What's red light therapy? Red light therapy before and after
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.
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.
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.
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.
What Are the Consequences?
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.
