1. Strengthen the management of paddy rice seedlings transplanted with water slurry. After transplanting, it is recommended to use deep-water live trees and shallow-water irrigated irrigation methods to ensure that the seedlings are planted early, and early delivery is achieved. The live field should timely irrigate the horse water after sowing to ensure early seedling emergence and early seedling development. At the same time, it is necessary to clean up and match the furrows in the fields so that it can be filled with water and energy, and a shallow water layer can be established in the 2 leaves and 1 heart period to promote early delivery.
2. Early application of sub-fertilizer After returning green plants to rice, timely recovery and application of fertilizer, generally 5 to 7.5 kg of urea per mu. After the first top dressing, 7 to 10 days, depending on the amount of birth in the field and the shade changes of the seedlings, appropriate balance fertilizer or strong fertilizer is applied, and 3-4 kg of urea per acre is used. For the lack of basic stems and seedlings, as well as machine-inserted, live-broadcast plots, appropriate additional application of tiller fertilizer.
3, timely control of weeds 5 to 7 days after transplanting, use butyl benzyl compound and other herbicides to control weeds in the field, after using drugs to maintain shallow water layer 5 to 7 days.
4. Strengthen pest prevention and control Every year, the occurrence of Laodelphax striatellus is large, the rate of poisoning is high, and rice stripe disease has a tendency of pandemic. Therefore, in addition to transplanting with drugs, the first should be carried out immediately after the planting of rice for 3 to 5 days. Medications are given again every 4 to 7 days. Indica rice was used 3 to 4 times, and hybrid rice was used twice.
To promote the transformation of seedlings, improper management of fertilizers, or abnormal weather and other unfavorable factors resulting in the failure of fresh seedlings, spraying appropriate growth regulators in time to promote seedling transformation.

Hyaluronic acid is a high molecular weight polysaccharide with D- glucuronic acid and N-acetyl-glucosamine as repeating structure unit. Because of the action of hydrogen bond between the monosaccharide in HA linear axle, HA molecular forms a rigid screw column structure in space. Strong hydrophilic properties exist due to the large amount of hydroxyl groups. Furthermore, HA has a special water binding function and binds its water very strongly, so that it has strong water retention. Theoretically its binding water capacity is up to 500 ml/g as an ideal natural moisturizing factor.
HA is also one important component of the skin. It can prevent skin from aging
and improve the appearance and tactile sensation of skin.
A part of low molecular weight HA can penetrate into dermal layer to control
the mid-metabolism, and make the skin moist, smooth and elastic. Therefore the
cosmetic functions of HA are its resistance against skin wrinkles and its
general health protection. HA is not only a good skin moisturizer, but also
promotes cell' s metabolism of skin. So HA stands for bio-mimetic cosmetics.
Hyaluronic acid is a natural part of the human body why it is highly suitable for many applications within the field of medicine and related aids.
