Abstract

The invention discloses a stevia glucoside compound liquid fertilizer and a preparation method thereof. The fertilizer comprises multiple nutrient elements and is prepared by mixing stevioside, potassium dihydrogen phosphate, urea, potassium sulphate, zinc sulphate, boric acid, citric acid and water. The fertilizer is developed according to the nutrient characteristics and the law of fertilizer requirements of crops and vegetables, and suitable for the farm and greenhouse production of crops and vegetables. The fertilizer can not only provide multiple nutrient elements required by the growth process of the crops and the vegetables and reduce the pollution of the fertilizer application to the soil and groundwater, but also regulate the balance of the nutrient elements in the crops and vegetables, improve the quality and increase the output. The preparation method has the advantages of simplicity, low cost and suitability for wide popularization.

Description

technical field [0001] The invention relates to a fertilizer, especially a stevioside compound liquid fertilizer and a preparation method thereof. technical background [0002] Crop quality refers to the quality of crops and vegetable target products required by human beings. Agricultural products that can meet the quality requirements of various human products to the greatest extent are called high-quality agricultural products. With the development of the market economy and the improvement of people's living standards, crops and vegetables not only need higher and more stable yields, but also have better and more comprehensive product quality. [0003] Stevioside is the extract of stevia rebaudiana. Stevioside has the characteristics of high sweetness (200-300 times that of sucrose) and low calorie (only 1 / 300 of sucrose), so it has attracted people's attention and attention. [0004] Many scholars have found that stevia liquid extract applied to the soil can promote roo...
