Causes of Pathogenic Fruit Defoliation mainly occurs in weak tree and old tree. The author believes that this disease is mainly caused by pests and diseases, improper fertilization, poor drainage, excessive pruning in summer, frost damage in winter, sunburn, and excessive results. The prevention and treatment methods will increase the application of organic fertilizer, rational application of nitrogen, phosphorus, potassium and trace elements, increase tree vigor, and increase resistance to disease. Minimize wounds while pruning, and apply 5 bpmite lime sulfur to large wounds. Collect dead and burned branches, prevent dried stem pests, and reduce sources and wounds. For lesions confined to the surface only, they should be promptly scraped after the spring, and 402 anti-disease agents should be applied 50 times at the wound, and then be coated with Bordeaux fluid or directly coated with 5 Baume degree lime sulfur. Before severely diseased fruit trees germinate, spray 402 anti-disease agent 300 times. The growth period is combined with other disease prevention and spraying protection on branches.
Hyaluronic Acid For Skin, Sodium Hyaluronate is well known as the best [Natural Moisturizing Factor". For Hyaluronic Acid Cream . In the early 1980s, the excellent moisturizing function of Sodium Hyaluronate has been widely concerned by
international cosmetics industry. With its unique film-forming and hydrating
characteristics, Hyaluronic Acid Powder Cosmetic Grade is used as a highly effective humectants in
cosmetics. It attracts moisture to the skin and hold moisture in the skin,
which preserve skin smoothness, suppleness and elasticity. 1 gram of Hyaluronic Acid Powder Cosmetic Grade is able to retain up to 1000 gram of
water. So it is regarded as the [key to the fountain of youth".

Moisturizing is the most important effect of Sodium Hyaluronate in cosmetics products. It can be hydrated shell
in skin surface and make the corneum hydration and softening. Compared with
other humectants, Sodium Hyaluronate is less effected by the environment as it
has the highest hygroscopic capacity in a relatively low humidity (e.g., in a
dry winter), but has the lowest hygroscopic capacity in a relatively high
humidity (e.g., in a damp summer). This unique property of Sodium Hyaluronate
makes the skin adapt to different seasons.
(2) Skin nutrition effect
Sodium Hyaluronate is the inherent biological materials of skin. The exogenous
Sodium Hyaluronate can complement the endogenous Sodium Hyaluronate. Low molecular Sodium Hyaluronate can
penetrate into dermis directly to improve the nutrient supply.
(3) Skin repair effect
There is some evidence that topically applied Sodium Hyaluronate can reduce
skin irritation
from various causes. During clinical trials it was also shown that this
ingredient is effective in promoting healing and fighting inflammatory
conditions of the skin. Sodium Hyaluronate serves as a free radical scavenger
and antioxidant, helping to protect the skin from the aging effects of
excessive sunlight exposure.
(4) Emollient and Film-forming
Sodium Hyaluronate is high polymer with high lubrication and film-forming.
Sodium Hyaluronate contained in cosmetics creates protective film on the
surface of skin, which retains moisture, and at the same time prevents moisture
in the skin from evaporation, so that improves freshness of the skin.
(5) Thickening
Sodium Hyaluronate solution have
high viscosity, and 1% solution is gelatinous. It can be added to cosmetics to
improve the thickening and stability.
Pay attention to the prevention and treatment of fruit tree gum disease in spring
Fruit tree gum disease mainly harms the trunk and main branches of peach trees, plum trees and other fruit trees. Swelling at the site of the disease, after the brown part of the wood becomes brown, a clear gel is secreted from the lenticels or the wound. It gradually turns yellow-brown to brown in contact with the air. It becomes a black lump over time and the bark at the site of the disease is rough and turtles. Cracked, difficult to heal, when the disease is severe, the tree vigor is weakened, and even the whole plant dies.
