The planting density of potato is usually determined according to the leaf area index, and the reasonable leaf area index of the potato is 3.5-4.0. The leaf area size is mainly determined by the planting density. The higher the density, the greater the leaf area index. Conversely, the smaller the density is, the smaller the leaf area index is.
Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from bovine vitreous in 1934 by Meyer, Professor of Ophthalmology at Columbia University. With its unique molecular structure and physicochemical properties, hyaluronic acid shows a variety of important physiological functions in the body, such as lubricating joints, regulating the permeability of blood vessel wall, regulating the diffusion and operation of protein, water and electrolyte, promoting wound healing and so on.

Under normal circumstances, early maturing varieties have shorter plants and shorter leaf areas due to shorter plants. Therefore, early maturing varieties should be closely planted; late maturing varieties have tall plants, long growing seasons, and planting densities should be thin; fertile land nutrient supply is strong, plants are tall, leaf area is relatively large, planting density should be thin, infertile land, lack of nutrition, plants Thin, small leaf area, planting density should be large; with irrigation conditions should be thin, dry land should be dense. In addition, the use of different planting density is not the same, the cultivation of commodity potatoes should be thin, seed production should be dense; French fries processing purposes should be thin, starch processing purposes should be dense.
Biochemical drugs with high clinical value are widely used in various ophthalmic operations, such as lens implantation, corneal transplantation and anti glaucoma surgery. It can also be used to treat arthritis and accelerate wound healing. When used in cosmetics, it can play a unique role in protecting the skin, keep the skin moist, smooth, delicate, tender and elastic, and play the role of anti wrinkle, anti wrinkle, beauty care and restoring the physiological function of the skin.
