Cucumber seed disinfection to prevent diseases

Cucumber seeds have pathogens such as fusarium wilt, anthrax, blight, and keratoderma. Therefore, cucumber seeds should be surface-sterilized before germination. There are three main methods.

Soaking in warm soup: Put the dry seeds in warm water of 55°C~60°C for about 10 minutes. The process should be constantly stirred, then cool down to 28°C~30°C for 4-6 hours, wash and clean.

Pharmacological disinfection method: soaking seeds with active ingredient 0.1% carbendazim hydrochloric acid for 1 hour, rinsing with fresh water, and soaking in fresh water for 4 hours, can be soaked with germination.

Membrane treatment: Some cucumber seeds have been treated by the seed production unit with a seed film containing fungicides and various trace elements. The treatment with the seed coating has a good bactericidal effect. Treated seeds can be directly soaked in germination or live.

After the seeds are sterilized, they are washed and washed again. The water is drained off, wrapped in a cloth, placed under a temperature of 27° C. to 30° C., and the seeds are often turned during the germination process so that the seeds are subjected to a uniform temperature. After about 24 hours, the seeds are subjected to uniform temperature. When budding begins, when the seeds are exposed to the root tips, the temperature can be appropriately reduced, and the temperature can be maintained at 22°C to 26°C. After about two days, the seeds can be released. If the seedlings do not sow well after germination, use a wet towel to wrap the seeds in a cool place at about 10°C to prevent the shoots from continuing to grow. This practice is called "sprouts."

Hyaluronic Acid Eye Drops Sodium Hyaluronate (HA), Pure Hyaluronic Acid could be used in eye surgery, such as Hyaluronic Acid Eye Drops, corneal transplantation, cataract surgery, glaucoma surgery, and surgery to repair retinal detachment.


Eye Drop Grade Hyaluronic Acid Powder is an important component of intercellular substance, eye vitreous body, joint fluid and other connective tissue. It acts the important physiologic roles in holding body's moisture, maintaining extracellular space, adjusting osmotic pressure, lubricating and promoting cells to repair in the body. Sodium Hyaluronate can be used as viscoelastic agent inintraocular lens implantation operation, as the filler in the osteoarthritis and rheumatoid arthritis and otherjoint surgery, as a medium widely used in eye drops, it also can be used to prevent postoperative adhesion and facilitate the wound heal. The compounds formed by the reaction of Sodium Hyaluronate with other drugs play a drug release effect role, thus achieve the purpose of drug targeted and time controlled release.


With the development of medical technology, Sodium Hyaluronate has been more and more widely used in medical applications. In 1976, Sodium Hyaluronate was first commercialized and used as ophthalmic viscoelastic agents, which is a significant progress in the ophthalmic industry. In 1987, Sodium Hyaluronate for intra-articular injection came in to the market. In 1990s, the large-scale production of Sodium Hyaluronate by fermentation made the cost lower, thus products containing Sodium Hyaluronate such as eye-drops, dermal fillers and other Sodium Hyaluronate preparations started to be used extensively.
