1. The occurrence of sown mushrooms is too large and the sowing is uneven, which can lead to the appearance of mushrooms. Therefore, the seeding rate should be controlled at 0.2-0.3 kg/m2.

The sowing method can be used for layer broadcasting, mixed broadcasting or broadcasting, and it is better not to use soaking.

2. If strains are ageing, if aging bacteria are used, although the germination and colonization of mycelium are normal, the first wave mushroom yield is also good. However, the yield of the second and third tide mushroom was significantly reduced, and the overall yield was reduced. Therefore, care must be taken when buying strains.

3. Large temperature difference leads to death of mushroom buds During the fruiting period of the straw mushroom, ventilation and water spray management must maintain the cultivation environment at a constant temperature as much as possible. Ventilation can only be carried out slowly, and the sudden changes of the climate are closely watched. Window ventilation. When water is sprayed, be careful to use the same water temperature as room temperature.

4. Culture materials acidified acidified culture material, mycelial growth is weak and weak, non-glossy feeling, fruit body is both small and small, and easy to break the membrane to open the umbrella. At the same time, there are a lot of ghost umbrellas. The method of preventing acidification, in addition to adjusting the pH value when preparing the culture material, should also manage the moisture after sowing, and spray 0.5% lime water instead.

5. If the material is too loose, the material will be so severe that the mycelium will break, the culture material will become thinner, and the amount of mushrooms will decrease. So after going to bed and sowing, we must pay attention to slightly compacting the culture material. If the stacking method cultivation. The heap shape should not be high.

6. Diseases and insect pests using deteriorating raw materials or culture materials fermentation, disinfection and other pretreatment is not complete, or cultivation in unhygienic places, can lead to a large number of breeding of bacteria and pests. Causes a large number of deaths, rots, or teratogenesis of the mushroom on the bed.

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".

The effects are as follows:

(1) Moisturizing effect 
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.
