Blackberry is a genus Rubus, which is native to North America. In 1986, the Institute of Botany, Chinese Academy of Sciences (Nanjing, Jiangsu) was first introduced from the United States. Blackberry self-fruited, flowering 15 to 20 days, fruit development period of about 40 days, fruit ripening period of 20 to 30 days. The young fruit is green, and it turns red first when it matures, and then gradually deepens into purple black. Plants enter the early stage of the fruiting period, and generally the fruit can be seen in the year of colonization. In the second year, the output of each 666.7m2 is about 300-400kg, and the highest is 800Kg. In the third year of entering fruitful period, the output per 666.7m2 was 750-1000kg, and the highest was 1600kg. The result was not obvious every other year. Such as good management, sustainable and stable production, economic life of 10 to 15 years. The first year of life above the ground, the perennial underground, life cycle of 15 to 20 years, the fruit is rich in C, E, B1, B2 and other vitamins, also contains more than 20 kinds of amino acids, higher SOD, pectin substances and potassium sodium, Magnesium, zinc, iron and other minerals, including selenium content as high as 2.17 mg / g, is 6 to 7 times that of apple, 2 to 27 times that of citrus. The ripe fruit of blackberry is purple-black, sparkling and bright, soft and juicy, sweet and sour. It can be fresh and suitable for processing. Fresh fruit can be frozen or made into juices, beverages, jams, canned sugar, wine, and more. Blackberry fruit is rich in nutrients, and various nutrients are basically preserved after processing. As the blackberry is a rare fruit rich in various vitamins, amino acids, and human anti-aging substances, it has become more and more popular.
1 Requirements for environmental conditions
Temperature: Flower bud differentiation requires a certain low temperature, that is, the temperature below 7°C takes about 700 to 800 hours. The winter extreme temperatures in the regions where blackberries are grown should not fall below -10°C, otherwise freezing damage will occur. During the fruit enlargement period, the temperature should be controlled within a certain range, and there should be a suitable temperature difference. For example, the blackberry planted in the greenhouse should keep the daytime temperature within the shed at 25-32°C during the berry expansion period, and maintain the temperature at night. 10 ~ 16 °C, day and night temperature control above 10 °C.
Moisture: Wet and wet, resistant to drought, relatively resistant to drought, to achieve high yields and high quality, the soil is often required to remain moist, but it can not accumulate water. Relative soil moisture content must be controlled at 30% to 35%. Blackberry planted in the greenhouse before the bud to flowering, relative humidity within the shed is controlled at 70% to 80%, in order to facilitate the growth of new shoots; before flowering to berry enlargement, the relative humidity of about 60% is appropriate to facilitate Pollination and increase the rate of fruit set; after the berry enlargement to the end of harvest, relative humidity of 60% to 70% is appropriate.
Soil: The most suitable soil pH is 6 to 7, and organic matter content is 2% or more. Well-drained sandy loam is better.

This variety is hi light, drought tolerant and can tolerate low temperatures around -15°C. It is more susceptible to damage by Star Longhorn.
3 Domestic resources
Blackberry cultivation in China began in the 1980s and was first introduced in the 1980s. In 1986, it was the first small-scale trial planted and promoted in Jiangsu Lishui, Jiangsu Province, China, now Jiangsu, Hunan, Hubei, Guizhou, The planting area of ​​blackberries in Shandong and Anhui has reached more than 10,000 mu. In Jiangsu province, which is dominated by hot and humid blackberries, it has developed rapidly in the past 10 years. By 2000, the cultivated area is about 500 hectares, and the total output is about 10,000 tons. Baima Town (known as the hometown of China's blackberry) in Lishui County, Jiangsu Province currently has a cultivated area of ​​10050 mu, accounting for 72% of the total economic forest fruit area in the town and an average yield of 750 kg per mu.
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.
