One is that the seedbed is uneven and the humidity in the beds is inconsistent. Second, the seeding techniques are not closed. The seeds are not evenly distributed. Third, the environmental conditions in the bed are inconsistent. The central temperature of the seedbed is relatively high, and the emergence is early, and the survival rate is high. Instead, the seedbed is high. The emergence of the surrounding location was later. To overcome the emergence of irregular seedlings, according to the above reasons, the seeds with high germination rate and strong germination potential can be used. The bed soil should be leveled, the seeding should be uniform, and the soil covering and covering measures should be as consistent as possible. Seedlings unearthed in the top shell.
The top shell of seedlings is mainly caused by two reasons: one is that seeds are stored for a long time and the seed shell is too hard; second, the seeds are not mature enough and their vitality is low. When the seedlings are unearthed, they are unable to shell off. When the bottom water is sown at the time of sowing or the soil is too thin, the seeds have not yet emerged, and the topsoil has dried out, making the seed coat dry and hard, and often cannot be shed smoothly. When planting, the cover soil is too thin, or the soil is too light and the pressure is too small. It will also make the seedlings “ear hat†unearthed. The measures to prevent hat seedlings are: use new species of the year or 1-2 years of Chen species. The cover soil should not be too light or too thin. If it is found that the seeds are covered with shells, a layer of fine soil should be covered in time.

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.
Photobiomodulation
In biological systems, there are various instances of light-induced photochemical reactions. Light interacts with photosensitive cells in our retinas called photoreceptors to give us vision. A photochemical reaction happens when light is absorbed by these cells, transforming light energy into electrical impulses that are delivered to the brain's visual processing areas. Another photochemical event is the creation of vitamin D in our skin. When the ultraviolet B (UVB) wavelength of sunlight contacts our skin, it transforms 7-dehydrocholesterol, a naturally occurring type of cholesterol, to vitamin D3. The harmful consequences of a lack of light on the human body are widely documented. Seasonal affective disorder (SAD) and vitamin D deficiency, which causes rickets, are two instances.
Photobiomodulation (PBM) is the word for the mechanistic/scientific foundation of this photonic speciality, while photobiomodulation treatment (PBMT) is the term for its therapeutic application. The initial version of PBMT was created in the 1960s. The early years of this nascent photonic application were marred by a slew of issues, including a lack of consistency in nomenclature. Biostimulation, Cold/Cool Laser, Low Level Laser Therapy, Soft Laser, and Low Power Laser Therapy were among the terminology introduced. PBM and PBMT are currently the terminology of choice, according to recent agreement in the profession.
PBMT was added to the National Library of Medicine MeSH database in 2015 as an entry term to the existing record of laser treatment, low-level, owing to Dr. Praveen Arany's work. In conclusion, PBM and PBMT are precise and explicit terminology for this crucial and effective therapeutic use of light.
