With the continuous improvement of people's living standards, the most food safety and quality are also paid more and more attention. Green vegetables, organic products and selenium-enriched products are increasingly favored by consumers. Today, Xiaobian is talking about what is a selenium-enriched product? And three methods of selenium application for selenium-enriched garlic. First, selenium-enriched products For selenium-enriched products, the most important step is to apply selenium. The three methods of selenium-enriched garlic are: soaking seeds, applying selenium in the soil, and spraying on the foliar surface. Second, soaking seeds Before sowing, the seed soaking operation is required. The seed is placed in the 1002/μg one kilogram sodium selenate solution for a few hours. This operation is beneficial to increase the selenium content, promote the germination of the garlic seeds, and increase the garlic yield. Third, the soil is applied with selenium Before sowing, 13 g of sodium selenate was applied per mu of land, and it was necessary to apply it with other base fertilizers when fertilizing. In the fertilization, it should be evenly applied in the seeding ditch, which can increase the harvesting yield of the garlic and increase the selenium content. Fourth, foliar spray One month before picking, sodium selenate is formulated into a concentration of 100/μg one kilogram, and 5g of pure selenium is applied per acre. It is evenly spread on the garlic leaf surface when applied, which can effectively increase garlic. The output is about 10%, and it is beneficial to enrich pure selenium. Five, matters needing attention 1. A trace element necessary for the growth of selenium garlic can effectively improve the disease resistance of garlic, but the amount of selenium applied can not be too much, and the matter must be reversed. Too much will lead to poisoning, and it is enough to maintain proper amount. 2. When spraying selenium, you can choose the method of soil application and spraying, but in either case, it should be sprayed evenly. 3, when spraying selenium, it is best to choose sunny before 9 am, or after 5 pm on a sunny day, in the rainy season, should be sprayed with selenium after the rain.
Overview: Axitinib is a multi-targeted small molecule inhibitor, the main targets are VEGFR, Kit, PDGFR, RET. The currently approved indication for the market is the second-line treatment of advanced renal cancer, which means that axitinib can be selected for advanced renal cancer after the failure of the chemicalbook treatment of Sutent. In addition to renal cancer, this drug has also been tried by patients for liver cancer, sarcoma, neuroendocrine tumors and other solid tumors that are relatively sensitive to anti-angiogenic drugs and have a rich tumor blood supply, and has certain curative effects.
Introduction:Axitinib is a white powder with a melting point of 218.4°C, slightly soluble in polyethylene glycol 400, slightly soluble in methanol or ethanol, very slightly soluble in acetonitrile, and almost insoluble in water. The solubility in pHChemicalbook1.2 hydrochloric acid solution at 20°C is 0.8 mg/ml, and the solubility in pH6.8 phosphate buffer solution is 0.2 μg/ml, which are typical pH-dependent drugs.
