In recent years, most farmers have unhealthy habits of unreasonable fertilization. In addition, many years of heavy crops in many areas have directly led to problems such as soil quality degradation, soil compaction, excessive heavy metals, and decreased organic matter, which have brought agricultural production. huge loss. The way to improve this situation is actually very simple, that is, using quicklime. Although the use of quicklime is not difficult, but also pay attention to some misunderstandings, otherwise it will have the opposite effect. The following small series of Huinong.com summarizes some common misunderstandings of quicklime.
1, pay attention to avoid the wet reaction
Many people will still use it after the lime is damp. In fact, this is not right. After purchasing the raw lime, it should be covered or stored in the warehouse to avoid water or moisture absorption before use. Otherwise, chemical reaction will occur, and calcium hydroxide will grow, and then it will lose its proper effect when used in the ground.
2, pay attention to the usage
Under normal circumstances, the amount of quicklime per acre is generally about 50-100 kilograms, even if the amount of heavy acid soil per acre should not exceed 150 kilograms. Many people use too much, which will cause the rapid decomposition and loss of organic matter in the soil and the reduction of humus, on the other hand, the loss of nutrients, and thus the soil fertility.
3, pay attention to the use of ground characteristics
Quicklime is an alkaline substance. Alkaline soil (pH greater than 7.5) can no longer be used. Neutral soil should be used as little as possible. For sites with heavy viscosity, strong acidity, deep ploughing, and dry land, lime can be applied more appropriately.
4, pay attention to the use of methods
1 quicklime can not be mixed with organic fertilizer; 2 quicklime can be used to increase the amount of use when used together with acid fertilizer; 3 quicklime can not be used together with water-soluble phosphate fertilizer and ammonium nitrogen fertilizer.
5, pay attention to the use cycle and crop type
Under normal circumstances, quicklime can be used once every 2-3 years, and cannot be used in large quantities for years. The use of quicklime as a whole includes peas, beets, tomatoes, and cucumbers. Therefore, not all crops can use quicklime. This misunderstanding should be remembered.
The above is a common misunderstanding of quicklime. When you use it normally, you only need to pay attention to avoid these misunderstandings, and you can fully exert the effect of quicklime.

Photobiomodulation (PBM) describes the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying. One of the organ systems of the human body that is most necessary to life, and whose optimum functioning is most worried about by humankind in general, is the brain.
PBM light therapy, also known as photobiomodulation therapy, has been shown to have several benefits for brain disorders. This therapy involves using low-level light therapy to stimulate the cells in the brain and promote healing and regeneration. Here are some of the benefits of PBM light therapy for brain disorders:
1. Neuroprotection: PBM light therapy has been found to have neuroprotective effects, meaning it can protect the brain cells from damage and degeneration. It can help reduce inflammation and oxidative stress in the brain, which are common factors in many brain disorders.
2. Improved cognitive function: PBM light therapy has been shown to enhance cognitive function, including memory, attention, and problem-solving skills. It can stimulate the production of brain-derived neurotrophic factor (BDNF), a protein that promotes the growth and survival of brain cells.
3. Reduced symptoms of depression and anxiety: PBM light therapy has been found to have antidepressant and anxiolytic effects. It can increase the production of serotonin, a neurotransmitter that regulates mood, and reduce the activity of the amygdala, a brain region involved in fear and anxiety.
4. Enhanced neuroplasticity: PBM light therapy can promote neuroplasticity, which is the brain's ability to reorganize and form new connections. This can be beneficial for individuals with brain disorders as it can help improve their ability to learn, adapt, and recover from injuries.
5. Accelerated healing after brain injuries: PBM light therapy has been shown to accelerate the healing process after brain injuries, such as traumatic brain injury or stroke. It can improve blood flow to the injured area, reduce inflammation, and stimulate the repair and regeneration of damaged brain cells.
