Study On Qi Chrysanthemum Standard Growth And Flavone Extraction Processing Techniques

This text is finished in Anguo of Hebei and China Agricultural University. Content include the dynamic accumulation laws of nitrogens, phosphoruses and potassiums. Regard sowing date, density, construct nitrogen quantity, phosphorus fertilizer quantity and potassium quantity as the factor .through making up and design, land for growing field crops plant, determine Qi the best agronomy measures. Study Qi chrysanthemum grow course nitrogens, phosphoruses and the dynamic accumulation laws of potassiums. At the same time at chrysanthemum total favonoid, chlorogenic acid and the contents of volatile oil determine regularlieses, in order to probe that it accumulates laws and define adopting and accept one bestly of Qi chrysanthemum. At material, try to find out Qi chrysanthemum best to draw the process conditions with Qi chrysanthemum.The result is the following:Pray for nitrogen phosphorus the contents of potassium greater than the nitrogen for the potassium chrysanthemum, the nitrogen is greater than the phosphorus.Pray for at potassium and nitrogen heavy change the whole the nutrient content changes of ones plant chrysanthemum, minimum phosphorus, and potassium, whether now at mmses plant suck most high content nitrogen potassium flower bud initial stage bud nitrogen, will reduce gradually as the bud grows up and blooms afterwards. Potassium, nitrogen demand are long-range in the demand for phosphorus during giving birth to entirely. So should pay attention to constructing the potassium, nitrogen in production.The flower is a body organ which prays for the chrysanthemum, percent of content of its nitrogen and potassium are changed with growth of the bud relatively bigly, just now bud high content, afterwards reduced; One hundred points of content of the phosphorus are relatively steady. It its merits attention to be at living beings the increases of quantity that spend although percent of content are reduced, the absolute content increases , for the demands of the nitrogen, phosphorus and potassium while guaranteeing to bloom, topdressing before the pregnant flower bud is essential.And chlorogenic acid one hundred a fen of contentseses present and blow laws that fall at two total flavonoids. It is about 8 mms of October 13 to appear in the colored diameter in the first peak period; appear for the second time. According to adopting and accept one bestly, though content high low quantity living beings one peak period, should adopt and accept in the second time peak period .Qi total favonoid draw at ethanols, water baths it draws to be for being best to draw terms in one hour technology. It is good twice to draw progression.
