Abstract

The liquid fertilizer is compounded with potassium dihydrogen phosphate, potassium nitrate, boric acid, urea, calcium nitrate, magnesium sulfate, zinc sulfate, copper sulfate, manganese sulfate, nickel sulfate, ammonium molybdate, iron trichloride or ferrous sulfate, sodium silicate or sodium metasilicate, cane sugar or glucose, nitric acid, phosphoric acid, alcohol, rosin and sulfuric acid. Applying the liquid fertilizer can avoid pollution to soil, environment and river, and its application is saving in labor. The liquid fertilizer is non-toxic, harmless and pollution-free.

Description

technical field [0001] The invention relates to a plant nutrient liquid fertilizer and a preparation method thereof. Background technique [0002] The current international trend of fertilizer development is high concentration and liquefaction. Liquid fertilizer is a typical high-concentration fertilizer, and liquid fertilizer has been widely used abroad. In the United States, liquid fertilizers account for more than 15% of the total amount of compound fertilizers and about 30% of the total amount of chemical fertilizers. At present, some progress has been made in the production, development, promotion and application of liquid fertilizers in China. In Xinjiang, which is a farm-type pilot, and Beijing, which is a rural-type pilot, the direct application of liquid ammonia has been listed as a popularization test project of the Ministry of Agriculture, and some results have been achieved. Utilizing the existing raw material resources and process conditions of domestic chemi...
