The invention belongs to the technical field of flue-cured tobacco cultivation and in particular relates to a method for potassium extraction and fertilization of Yunyan85 (flue-cured tobacco variety). The method is characterized by comprising the following steps of applying a potassic fertilizer to Yunyan; applying a certain amount of potassic base fertilizer to tobacco leaves when the tobacco leaves are grown; and topdressing the potassic fertilizer to flue-cured tobaccos before the flue-cured tobaccos enter into a fast growing period and after more than 50% of the flue-cured tobaccos bud for topping, wherein the application amount of a potassic base fertilizer is 60%-70% of the total application weight of the potassic fertilizer, the application amount of the topdressed potassic fertilizer before entering the fast growing period is 15%-20%, and the application amount of the topdressed potassic fertilizer is 15%-20% after more than 50% of the flue-cured tobaccos bud for topping. According to the method, the fertilization period and the additional fertilization period and amount are accurate, the waste of the potassic fertilizer can be reduced, the potassium content of the tobacco leaves can be improved while guaranteeing yield. The collected tobacco leaves are analyzed, and the potassium content of the tobacco leaves is measured to be 3.13%, which is higher than the standard that the potassium content of high-quality tobacco leaves is more than or equal to 2%.

The invention discloses a high-grade flower culture medium, and belongs to the technical field of soilless culture. The culture medium is characterized by being prepared from the following components in a volume ratio: 50-70 percent of vinegar residues, 10-25 percent of vermiculite, 15-25 percent of plant ash and 5-10 percent of perlite. In the medium, the total nutrition content is 1-5 percent, the moisture content is less than or equal to 50 percent, the content of organic matters is more than or equal to 25 percent, the total porosity is 60-80 percent, the volume weight is 0.2-0.6g / cm<3>, the gas-water ratio is 1:(2-4), the EC value is 1-3.5mS / cm, and the pH value is 6.0-7.5. According to the culture medium, the vinegar residues and other organic wastes are mainly utilized as raw materials and are treated by means of high-temperature fermentation to produce a soilless culture medium, so that waste materials are changed into valuable materials, and harmful materials are turned into advantageous materials. The high-grade flower culture medium has the advantages of low cost, light texture and complete nutrition, is suitable for high-grade flower culture, and is an excellent soilless culture medium for horticultural plants.
