Abstract

The invention discloses a method for the Radix Platycodonis polysaccharide regulated preparation of a nutritional liquid fertilizer containing nano-selenium. The method comprises the following steps: preparing a nano-selenium solution from Radix Platycodonis polysaccharides and seleninic acid by using an ascorbic acid reduction technology; preparing a soybean meal composite amino acid stock solution from soybean meal by using a sulfuric acid hydrolysis technology, adsorbing and decolorizing the stock solution by active carbon modified through 0.25% KOH solution treatment, filtering the stock solution, sterilizing the obtained filtrate by cobalt60 to prepare a soybean meal composite amino acid solution; and uniformly mixing magnesium sulfate, zinc sulfate, manganese sulfate, ferrous sulfate, borax, copper sulfate, sodium molybdate, silica, Arabic gum and water with the nano-selenium solution and the soybean meal composite amino acid solution to prepare the nutritional liquid fertilizer containing nano-selenium. The soybean seed composite amino acid solution and trace elements are compounded to make the trace elements exist in a chelated state, so the utilization rate of the trace elements is increased, the absorption of the plants to macro-elements is promoted, the crop yield is increased, and the crop quality is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for regulating and preparing nutrient liquid fertilizer containing nano-selenium by platycodon polysaccharide. Background technique [0002] China is a big selenium-deficient country. Soil surveys show that 72% of my country's areas are selenium-deficient and low-selenium areas, and about two-thirds of the country's population has insufficient selenium intake to varying degrees, seriously affecting the health of local residents. Therefore, the development of selenium-enriched fertilizers and the development of selenium-enriched agricultural products have become research hotspots in the fields of agricultural science, food science and medicine. [0003] At present, the common selenium-containing fertilizers on the market are mainly inorganic selenium fertilizers. Due to the influence of soil fixation and air drift when inorganic selenium is sprayed on the...
