Elaborate In the selection of fresh corn, it should be strong in resistance, high in yield and good in commodity. It is mainly composed of corn with high content of sweet corn and lysine, and it can be reasonably matched in the early, middle and late days. Wrong time broadcast, staged listing to create conditions. Seed coating before sowing to control underground pests. Early broadcast It is necessary to carry out seedling transplanting and plastic film mulching cultivation mode. In the sowing date, it is necessary to grab the early catching, spring sowing fresh corn should be sooner rather than later, in order to facilitate the early listing; autumn should be properly broadcasted late, and listed in mid-October to meet market needs. . Isolation planting Time isolation, sowing period is more than 30 days; space isolation, above 500 meters, because sweet corn and high lysine corn are not isolated from ordinary corn, that is, the characteristics of high lysine corn and sweet corn are lost, meaningless, Therefore, it is necessary to isolate the planting to prevent stalking. Reasonable close planting It is necessary to be closely planted to make the structure of individuals and groups reasonable, to facilitate ventilation and light transmission, to reduce empty stalks, to promote good fertility, to mature early, and if the density is too large, the ears are small, and it is prone to large and small spikes, which are not neat, and there will be an empty stalk rate. The high phenomenon, if the density is too small, the output of the ear is small, the benefit is low, and the income is small, so it is reasonable to closely plant according to the characteristics of the variety, the good or bad soil, the amount of fertilization. Scientific fertilization First, the application of organic fertilizer, based on the base fertilizer, 4000-5000 kg per mu, but also with nitrogen, phosphorus, potassium fertilizer, to achieve organic, inorganic, micro-fertilizer combination, nitrogen, phosphorus, potassium. The second is to apply the fertilizer, mainly diammonium phosphate, about 10 kg per mu, the third is early topdressing, the mu is about 15 kg of urea, and the topdressing time is in the critical period of corn fertilizer, that is, the jointing stage begins. It is best to apply organic fertilizer and biological fertilizer to fresh corn, and apply 2000 kg of fermented fresh chicken manure per acre as base fertilizer, topdressing can be used for cake fertilizer, high fertilizer efficiency, long duration, and stamina, 150 kg of cake-feeding fertilizer. Strengthen management First, morning seedlings, early seedlings, early seedlings, seedlings, seedlings, strong seedlings, uniform seedlings, and do a good job of weeding and weeding, the second is drought and irrigation, met with drainage, and the third is disease prevention and pest control.

Glutathione powder plays an important role in preventing oxidative damage to the skin.In addition to its many recognized biological functions, glutathione has also been associated with skin lightening ability. The role of glutathione as a skin whitener was discovered as a side effect of large doses of glutathione. Glutathione utilizes different mechanisms to exert its action as a skin whitening agent at various levels of melanogenesis. It inhibits melanin synthesis by means of stopping the neurotransmitter precursor L-DOPA's ability to interact with tyrosinase in the process of melanin production.Glutathione inhibits the actual production as well as agglutination of melanin by interrupting the function of L-DOPA. Another study found that glutathione inhibits melanin formation by direct inactivation of the enzyme tyrosinase by binding and chelating copper within the enzyme's active site. Glutathione's antioxidant property allows it to inhibit melanin synthesis by quenching of free radicals and peroxides that contribute to tyrosinase activation and melanin formation. Its antioxidant property also protects the skin from UV radiation and other environmental as well as internal stressors that generate free radicals that cause skin damage and hyperpigmentation. In most mammals, melanin formation consists of eumelanin (brown-black pigment) and pheomelanin ( yellow-red pigment) as either mixtures or co-polymers. Increase in glutathione level may induce the pigment cell to produce pheomelanin instead of eumelanin pigments. A research by Te-Sheng Chang found lowest levels of reduced glutathione to be associated with eumelanin type pigmentation, whereas the highest ones were associated with the pheomelanin. As a result, it is reasonable to assume that depletion of glutathione would result in eumelanin formation. Prota [ observed that decreased glutathione concentration led to the conversion of L-Dopaquinone to Dopachrome, increasing the formation of brown-black pigment (eumelanin).
