Blueberries are sweet and sour, rich in nutrients, and can prevent brain nerve aging, protect eyesight, strengthen the heart, fight cancer, soften blood vessels, and enhance human immunity. As a small berry tree species with high economic value and broad development prospects, blueberries are known as the "king of berries." Blueberries are not only attractive in color, but also have a unique flavor. They can be eaten fresh or processed into a variety of foods suitable for all ages, and are deeply loved by consumers!
However, blueberry growers will find that the leaves will turn red during the growth process. What should we do?

1. Growth habits of blueberries
Blueberries like warm climates, are more resistant to high temperatures, like semi-sunlight environments, like humid environments, and are generally drought-resistant and waterlogged. They are suitable for planting in fertile, loose, and organic-rich acidic soils
1) . There are two types of blueberries: one is a low shrub, dwarf wild, small grains, and rich in anthocyanins; the second is artificially cultivated blueberries, which can grow to 240cm high, with larger fruits and full flesh, which improves the edible taste of wild blueberries and enhances the body's absorption of anthocyanins.
2) . Blueberries can grow multiple times in a growing season, and secondary growth is more common. In southern my country, blueberries have two growth peaks a year: the first is in May-June; the second is from mid-July to mid-August. The growth of seedlings is significantly accelerated in the third year after planting, and new branches sprout and grow vigorously, with an annual growth of more than 1 meter.
2. Why do the leaves of blueberry seedlings turn red?
1). Nitrogen deficiency will cause the leaves to turn red and fall off, so nitrogen fertilizer needs to be added appropriately.
2). Low temperature will also cause blueberry leaves to turn red, so you need to pay attention to heat preservation.
3). The red leaves of blueberry seedlings may be due to the high soil pH, so you need to choose the right soil when cultivating.
3.Chitosan Oligosaccharide: A Good Helper in the Growth of Blueberries.
Chitosan Oligosaccharide (COS) is derived from Chitin, it is a unique type of polysaccharide due to its high molecular weight, which makes it an ideal candidate for use in a variety of agricultural applications. COS can be used as a soil amendment, as it helps to reduce compaction and increase water retention. COS can also be used as a fertilizer, as it helps to increase the availability of nutrients to plants. Additionally, COS can be used as a growth promoter, as it helps to increase the rate of photosynthesis and improve crop yields. COS has also been shown to be effective in preventing And controlling plant diseases,such as root-knot nematodes!

Benefits of chitosan oligosaccharide in agriculture
Chitosan oligosaccharides is regulation of endogenous hormones. It is not only help plants fight disease but also break down trace metal elements in plant and animal residues and soil,thereby converting them into plant nutrients,enhancing plant immunity and promoting plant health.
Chitosan oligosaccharides can be sprayed on the leaves or flushed with fertilizer to achieve the following effects:
>Induce crops'stress-resistance, ignificantly increase yield.
>Control of various crop diseases caused by fungi,bacteria and viruses.
>As Biopesticide& Soil Treatment,it can control and kill nematodes,Optimize the flora ,Healthy roots.
>As Immune Booster,it can Induce plant immunity for plant diseases.
Chitosan oligosaccharide plays an important role in the growth of blueberries and has remarkable effects.
