Abstract

The invention relates to a fulvic acid fertilizer, and mainly provides a fulvic acid fertilizer prepared by using straw pulp black liquor. After the fulvic acid fertilizer is applied to the soil, it can balance the absorption of nitrogen, phosphorus and potassium by crops, improve the Soil, improve crop quality, improve crop stress resistance, promote crop early maturity, and increase crop yield; it is an efficient organic fertilizer suitable for field crops and economic crops.

Description

technical field [0001] The invention provides a fulvic acid fertilizer, which belongs to the field of straw pulp black liquor treatment. Background technique [0002] More than 80% of the raw materials of my country's papermaking industry are grass fibers. There are two main types of grass fiber papermaking, alkaline pulping and sulfite pulping, and the sulfite method is mainly based on the ammonium method. Alkali pulping is a method of treating plant fiber raw materials with an aqueous solution of alkaline chemicals to dissolve the lignin in the raw materials and separate the fibers into pulp. Ammonium pulping is a method of using ammonium sulfite and plant fiber raw materials The action of lignin in the medium produces easily soluble lignin sulfonate and dissolves to achieve the purpose of separating fibers. [0003] After alkaline pulping, about 50% of the fiber raw materials and most of the alkaline substances are dissolved in the cooking liquor to become black liquor....
