Abstract

The invention discloses a high-latitude region stevia rebaudiana special-purpose fertilizer. The high-latitude region stevia rebaudiana special-purpose fertilizer comprises the following raw materials in parts by weight: 25-35 parts of ammonium hydrogen phosphate, 5-15 parts of ammonium sulfate, 2-12 parts of rock phosphate, 10-18 parts of a kiln dust potash fertilizer, 0.2-0.8 parts of boron magnesium fertilizer zinc, 0.4-0.9 parts of hexaurea iron(III) trinitrate, 2-6 parts of ammonium magnesium phosphate, 0.5-1.2 parts of ammonium molybdate, 1-2 parts of a boron magnesium fertilizer, 5-10 parts of fermented corn straw, 2-8 parts of earthworm manure, 2-10 parts of Chinese medicine residue, 2-8 parts of bentonite, 20-40 parts of grape seed cake, 15-35 parts of rice bran, 5-15 parts of linen fiber composite clay, 1-4 parts of carbonized corncob powder, 1-2 parts of kaolin, 1-2 parts of fly ash, 2-4 parts of meerschaum, 1-6 parts of carboxymethyl cellulose, and 1-2 parts of brewer's grain. The nutrient element ratio is reasonable, the nutrition requirement problem of stevia rebaudiana can be solved after application, fertilizer utilization rate is increased, and the environment pollution due to fertilizer loss is reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for stevia in high latitude regions. Background technique [0002] Stevia is a perennial herbaceous plant of Compositae, native to subtropical South America. The roots, stems and leaves of Stevia rebaudiana contain steviol glycosides. Stevioside has the characteristics of high sweetness and low calorie, and has the effect of raising blood sugar, lowering blood pressure, promoting metabolism, and has certain auxiliary effects on obesity, diabetes, heart disease, dental caries, etc. Pay attention to become the "third sugar source" after sucrose and synthetic sugar. In recent years, as the demand for stevia has increased, the planting area in my country has also continued to expand. With the rapid development of the stevia industry, it is very important to plant stevia scientifically and rationally. However, the conventional fertilization method at this s...
