Shady net cultivation technology of summer parsley
Sodium Hyaluronate is very important for skin because it improves moisturization, maintains skin resilience, and reduces damage in the lower part of skin when the skin is damaged. It also acts like lubricant by causing collagen, a main constituent of skin, to move smoothly in between cells.
But from the age of 25, Sodium Hyaluronate in human body will lose gradually, only remaining 65% of young skin at the age of 30, only 25% of young skin at the age of 50.
With the increase of the age and the loss of Sodium Hyaluronate, the skin will lose elasticity and luster, aging, wrinkles and relaxation will be generated gradually.
Sodium Hyaluronate is so water-friendly and it has functions of the best moisturizing factor and prevents diseases such as skin infections by preventing the penetration of external substances such as bacteria.

First, choose the varieties of Shandong large leaf parsley and other plants higher, long growth period, high yield varieties.
Second, the fine soil preparation, full-root fertility coriander thick, suitable for loose fertile soil, soil preparation when plowing 25 centimeters deep, at the same time per acre Shi fermented organic fertilizer 4,000 to 5,000 kilograms, 耙 耙 , , ,, 畦 畦, 畦 畦 size It depends on the convenience of operation and the plots.
Third, fine sowing to ensure that the whole seedlings
1. Pre-seeding seed treatment: The coriander seeds are double-hanging fruit, and the seeds must be split before sowing. Since parsley is a cool and cool crop, sowing in summer must be carried out with low-temperature soaking and germination to facilitate emergence of seedlings. Seeds can be soaked with fresh water for 24 hours to fully inhale the seeds. Then wash the filter dry in a wet cloth bag and put it in the refrigerator at 8 to 10°C. Under conditions, germination for 5 to 7 days, until 30% of the seed can be sown. Unconditional wet cloth bags can also be hoisted to the depth of 20 to 30 cm above the surface of deep wells. This can also be achieved.
2. Seeding: As the coriander seeds are small, they can be sown with fine sand. Before sowing, the bottom of the plant should be poured with water. About 1.5 kg per mu should be planted. Seeds should be covered with fine soil after sowing, and the cover soil should not be too thick. Sparsely covered with straw, generally weeds such as grass, so as not to clump weeds.
4. After covering the shade nets, immediately erect a scaffolding 80 to 100 centimeters high. The shed is covered with a shade net. This will not only cool the shade, but also prevent rainstorms. During the period of coverage, it is not necessary to uncover the net whether it is sunny, rainy or even cloudy.
Fifth, strengthen the growth period management After the emergence of seedlings in a timely manner to remove the covering. Seedling fertilizer and water management, in principle, no drought or not pouring, less early pre-casting, late pouring, fertilizer-based nitrogen fertilizer, available urea, defecation water with water flushing. In addition, it can be sprayed once every 7-10 days with foliar fertilizer to promote growth and increase yield.
Sixth, timely harvest after emergence of 30 to 40 days, when the plant height of 15 to 20 cm can be pulled between harvesting and harvesting, each harvest should be topdressing 1 times. In the 10-15 days before harvesting, gibberellin combined with foliar fertilizer was sprayed together to increase the yield.
Therefore, it is regarded as an ideal "natural moisturizer" factor and widely used in cosmetics that suitable for different skins, climates and environments.
High molecular Sodium Hyaluronate can be formed breathable film on the surface of the skin, help the skin to lock moisture, and to prevent the invasion of bacteria, dust and ultraviolet, so that to protect the skin from damage.
Low molecular Sodium Hyaluronate, which is designed for better skin penetration, can penetrate into the dermis quickly, dilated capillaries slightly, promote blood circulation and metabolism, and so it has function of eliminating wrinkles, increasing skin elasticity and preventing skin aging.
