King Coconut Rapid Seedling Technology

First, seed collection and sowing

The exocarp of Dawang Coconut changed from blue to reddish-brown to purple-black, and the seed endosperm was hard, indicating that the seed was mature and could be harvested. After the seeds are harvested, they should be soaked in water or with straw for about a week until the peels are soft and the pulp is washed away with water, which can then be stored with the sowing or sand storage (not suitable for exposure or dehydration). When sowing, the temperature should be above 20 °C, such as spring. After sowing pay attention to moisture and cover shed, keep the light transmittance 30-40 °C appropriate. According to the experimental records, the sand bed was sown in May-October and germinated as soon as 15 days, and basically germinated after 2 months. After sowing in November, germination continued one month later, and a small amount of seeds germinated in the second spring. It can be seen that seeding at different times and the duration of germination are inconsistent. King coconut seeds and mice like to eat, so after the broadcast need to cover the rodent to prevent loss.

Second, nursery

Dawang coconut is a shallow-rooted species of fibrous roots. It responds sensitively to moisture. When it moves from the sand bed to the alfalfa, it is often damaged by some root systems, weakening the water absorption function, and causing the leaves to yellow or die. The seeds of Dawang Coconut contain nutrient-rich endosperm, which can grow without relying on foreign nutrients for a period of time after germination, so it is easier to transplant at the initial stage of germination and rooting. In view of this situation, after 1 month of germination, when only 1-2 roots have been grown in the roots, rainy weather should be used to transplant the sand bed seedlings into the depression. In order to save land, and centralized management of our approach is to directly transplant sand bed seedlings in nutritional bags for a year, often to keep the soil moist, urea fertilizer and fertilizer once every half a month, the concentration of 3-5%, the second year of spring election The rainy weather transplanted the seedlings into the depression. King coconut in the young age of sex hi Yin, so the summer should be placed in a shaded environment, the winter need to have straw or film covered with anti-frost winter. As long as the above points are achieved, the annual seedling height can reach 50-60 cm (natural height) and the ground diameter is 2-4 cm.

Third, cultivation and management

King Coconut prefers a warm, moist and well-lit environment. Planting sites should be deeper, well-drained, loose, fertile, or slightly acidic. The planting time should be considered from two aspects. First, King Coco Co., Ltd. prefers to be warm and tolerant and cold. The suitable temperature is 23-25°C. When the temperature drops below 15°C, it stops growing. The safe winter temperature is 10~12°C, and it has strong drought resistance. The second is that Dawang coconut is a partial negative light plant. It is afraid of strong light at the seedling stage. It should be planted in the climate conditions from April to May and from August to October. At this time, the temperature is suitable and the survival rate after planting is higher. After transplanting, the water was thoroughly sprayed and the nursery soil was often kept moist during the growth and development of the seedlings. Planting density depends on the size of seedlings to be cultivated, generally 80 centimeters and 80 centimeters is appropriate, 700 acres can be planted. After the seedlings are alive, nitrogen fertilizer is applied once a month during the growing season, and can be applied dry (shallow ditch shallow application), but also Water facilities, after the addition of phosphorus and potassium fertilizers after September. Weeds can be sprayed with herbicides, the concentration of which depends on the type of weeds and herbicides, and the general amount of glyphosate 0.5-0.7 two / 30 catties of water, spraying twice a year can be. As long as the water and fertilizer management is strengthened, after 5 years of cultivation, the natural height can reach 4.5-5.5 meters, the pole height 1.8-2.0 meters, and the 1-meter rod diameter can reach 40-60 centimeters, which is the standard seedling for landscaping.

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.
