Description
Technical Field
The invention relates to a liquid organic water-soluble fertilizer containing xylose mother liquor and a preparation method thereof, belonging to the field of plant nutrition.
Background
A large amount of chemical fertilizers are excessively applied in China for a long time, so that the utilization rate of the fertilizers is low, the nutrients are unbalanced, blind fertilization is realized, and a series of environmental problems such as soil hardening, soil microbial community loss, environmental pollution, nutrition enrichment and the like are caused. In recent years, the state guides the optimization and upgrade of fertilizer products, and the efficient novel fertilizer is widely popularized, wherein the novel fertilizer contains organic fertilizer. The organic liquid fertilizer is widely accepted because of good water solubility, simple use, comprehensive nutrients and quick fertilizer efficiency. However, the raw materials of the currently commonly used organic liquid fertilizers are generally prepared by hydrolyzing or fermenting or activating waste water, such as amino acid obtained by hair hydrolysis, biogas slurry obtained by fermenting livestock and poultry manure and household garbage, humic acid generated by alkalifying lignite, weathered coal and the like, and molasses liquid generated in the sucrose preparation process, and the raw materials have low organic matter content, unstable raw material quality and low crop utilization rate after application. In addition, in production, the particles are easy to delaminate due to uneven particle size; increased viscosity and poor flow; flatulence occurs due to the residual presence of certain microorganisms.
The xylose mother liquor is thick liquid with dark color left after xylose crystallization, and the main components are xylose, arabinose, glucose, galactose and other sugars. The total sugar content of the xylose mother liquor is different from manufacturers and batches, and the total sugar content is generally between 60 and 75 percent. Xylose accounts for 50-70% of the total sugar. The xylose mother liquor has high heterosugar content, so that the xylose in the xylose mother liquor has high solubility and cannot be crystallized by adopting a traditional method. If a chromatographic separation method is adopted, different sugars in the sugar can be separated, but because the sugars (xylose, arabinose and the like) in the sugar are low-value sugars, the chromatographic separation technology cannot be popularized due to high cost. At present, the utilization of xylose mother liquor mainly comprises the fermentation production of alcohols and yeast, the production of caramel pigment, the synthesis production of other glycosides and alcohols and the like as raw materials. However, most of the utilization approaches have the problems of complicated production process, high cost, small utilization amount and the like compared with the huge yield of the xylose mother liquor. Therefore, it is of practical significance to find a large number of ways to effectively utilize xylose mother liquor. Organic matters and nutrients in the xylose mother liquor are soluble raw materials, and sugar in the xylose mother liquor is monosaccharide. Compared with the conventional molasses liquid mainly containing cane sugar, the xylose mother liquid is composed of monosaccharide mainly containing pentose, has no other harmful impurities, can be quickly absorbed by plant roots and leaves, and is a good raw material for preparing the liquid organic water-soluble fertilizer.
