Problems solved by technology

[0008] But the former needs to add a lot of H 3 PO 4 and / or HNO 3 , which increases the cost, and the subsequent fermentation of liquid fertilizer will inevitably increase the processing time and the production cycle of the product; while the latter directly applies the ammonium pulping black liquor, and when used improperly, some reducing substances harmful to crops will be produced; at the same time The fertilizer has high moisture content, low active ingredients, and high transportation costs

Abstract

The invention relates to a fulvic acid flushing fertilizer and a preparation method thereof. The fulvic acid flushing fertilizer is mainly prepared by adding a soluble macro-element fertilizer into an alkali-ammonium sulfite mixed condensed straw pulp black liquid. The fulvic acid flushing fertilizer applied into soil can balance the absorption of crops to nitrogen, phosphor and potassium, improve the soil and the crop quality, enhance the crop resistability, promote the earlier ripeness of the crops, and improve the yield of the crops. The fulvic acid flushing fertilizer is a highly effective organic fertilizer suitable for field crops and economic crops.

Description

technical field [0001] The invention provides a fulvic acid fertilization and a preparation method thereof, belonging 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 cookin...
