In rural China, farmers grow vegetables, usually by seeding their own seedlings or buying vegetable seedlings for cultivation. Everyone knows that good seedlings can grow healthy and high-quality vegetables. So how do we choose when purchasing? The following small series will share with you the principle of vegetable seedlings purchase. I hope that everyone growers pay attention.
First, is the seedling strong?
Strong seedlings are an important material basis for the high yield of vegetables. In general vegetables, the external form of the strong seedlings is: the seedlings grow vigorously, the height is moderate, the size is neat, neither long nor aging, the leaves are large and thick, the leaves are normal, and the cotyledons and leaves are not early or yellow, roots Developed, high dry matter content; fruit buds of fruit and vegetable vegetables have early flower bud differentiation and good development.
However, the standard of strong seedlings of different vegetables is not exactly the same, such as cucumber: with 3 to 4 leaves, thick leaves, dark color, thick stems, short internodes, seedling height below 10 cm, cotyledons intact; tomato: with 8 true leaves , leaf color green, with flower buds but not open, stem diameter 0.5 cm, seedling height 20 cm or less; pepper: with leaves 10 to 12, leaves large and thick, leaf color dark green, stem thick 0.4 ~ 0.5 cm, high seedling height 15 ~ 20 cm, flower buds have been produced; eggplant: with 5 to 6 leaves, seedling height of about 15 cm, other with the same pepper.
Second, whether there are lesions on the leaves
The seedlings are sick, and the afterlife is endless. Therefore, before buying a seedling, you must carefully check whether there are lesions on the seedlings. If it is found that there are lesions on the leaves, it is understandable, and it can be cured by the medicine in the later management. If there are too many lesions on the leaves, do not buy them, so as to prevent the growth and production of the seedlings due to the disease. In addition, it is necessary to pay attention to whether there are seedlings with viral diseases. If the seedlings are found to be black and green, or if the leaves are streaked or deformed, they should be suspected of having viral disease. Do not use them, and do not buy them.
Third, whether the hormone is too heavy
Many vegetable growers have a misunderstanding of understanding, and the seedlings with dark green leaves and short stems are considered to be robust standards. Some nursery plants have penetrated the psychology of vegetable farmers, spraying a large amount of hormones during the process of raising seedlings. As a result, seed hormone poisoning is often caused by excessive hormones, which inhibits over-exposure. In addition to the black and green leaves and the short stems, the stems of these hormones are too brittle and easily broken. After planting, not only slow seedlings are slow, but also the growth in the later period is very poor, the yield is low, and it is easy to prematurely decay. Therefore, if the vegetable farmers see this seedling when purchasing the seedlings, they must not buy it to avoid loss.
If you want to grow high-yield vegetables, then strong vegetable seedlings are very important, so you must choose good vegetable seedlings for cultivation before transplanting. The above is the principle of vegetable seedlings shared by Xiaobian for your reference.

Red light therapy, also known as photobiomodulation or low-level light therapy, is a non-invasive treatment that uses red or near-infrared light to stimulate cellular function in the body. The therapy involves exposing the skin to specific wavelengths of light, typically between 600 to 1000 nanometers, which can penetrate the skin to a depth of about 5 millimeters.
Red light therapy works by stimulating the mitochondria in the body's cells, which are responsible for producing energy (ATP). The light energy absorbed by the mitochondria triggers a series of biochemical reactions that can enhance cellular metabolism and promote various therapeutic effects.
Some potential benefits of red light therapy include:
1. Skin health: It can improve the production of collagen and elastin, leading to improved skin tone, reduced wrinkles, and acne treatment.
2. Pain relief: It may help reduce inflammation and alleviate pain in conditions such as arthritis, muscle strains, and joint pain.
3. Wound healing: Red light therapy can promote tissue repair and accelerate wound healing by stimulating cell growth and circulation.
4. Hair growth: It has shown potential in stimulating hair growth and treating conditions like androgenetic alopecia (pattern baldness).
5. Mood enhancement: Red light therapy may have positive effects on mood and mental well-being by improving serotonin levels and reducing symptoms of depression and anxiety.
