The invention provides a technology for producing a fulvic acid fertilizer and high-strength corrugated paper by using whole cotton stalks as raw materials. With the whole cotton stalks as the raw materials, by a weakly-acid imidized machine pulp pulping technology, through optimal combination of the cooking temperature, the cooking time and the pH value as well as high-concentration pulping and other pulping technological links, pulping red liquor rich in fulvic acid is prepared for producing the fertilizer, and high-performance pulp with a relatively light color is produced for producing thehigh-strength corrugated paper. By the technology, defects and shortcomings of a strong-alkali and strong-acid technology are avoided, differences in traits, components and structures of the whole cotton stalk raw materials are overcome, fulvic acid producing active components contained in cotton stalk cores, cotton stalk pulps, cotton boll shells and cotton stalk skins in the whole cotton stalksare effectively utilized, the advantage of combination of long and short whole cotton stalk fibers is effectively played for producing the high-strength corrugated paper, comprehensive utilization ofwhole cotton stalk resources is achieved, and a technological path for industrial and commercial utilization of the whole cotton stalk raw materials is opened up.
