Organic fertilizer product used for promoting degradation of nicotine

Abstract

Aiming at the problems of easy loss of organic nitrogen in a tung cake and easy cause of wilt of the tung cake, the invention provides an organic fertilizer product used for promoting the degradationof nicotine. A preparation method comprises the following steps: taking a material with high content of starch, washing out the crude starch with water, carbonizing a residue and a tung shell at the high temperature to obtain activated carbon, adding inorganic nitrogen, phosphorus, potassium and nicotine into the tung cake for fermenting and degrading, then adding the activated carbon to obtain amixed suspension, adding an acrylic acid and a crosslinking agent into the crude starch, reacting for a short period of time, then adding the mixed suspension, stirring evenly, and continuing to reactto obtain the organic fertilizer product. In the method, the starch in a root tuber of a plant is directly transformed into a water absorbent gel particle, and the organic matter and the activated carbon are immobilized in the gel, so that the production cost of a fertilizer is reduced, and the purpose of water retention of the fertilizer is also fulfilled. The activity of nicotine degradative bacteria is guaranteed in the whole production process, and the multiplication and the growth of microorganisms continue to be kept under the condition of sufficiency of the nutrient substances and thewater retention gel.

Description

technical field [0001] The invention relates to an organic fertilizer product for promoting the degradation of nicotine, which belongs to the technical field of fertilizer preparation. Background technique [0002] Nicotiana is an annual or limited perennial herb of the family Solanaceae, with a slightly lignified base. Inflorescences terminal, paniculate, many-flowered; capsules ovate or oblong, about as long as persistent calyx. The average contents of chemical components in flue-cured tobacco are: 23.08% of total sugar, 19.63% of reducing sugar, 2% of total nitrogen, 1.99% of nicotine, 10.32% of protein, Schmuck value 2.45, total sugar / nicotine ratio 14.21, total nitrogen / nicotine ratio 1.15. It also contains functional ingredients such as rutin, solanesol, and chlorogenic acid. However, the soil where tobacco has been cultivated contains a small amount of harmful substances such as nicotine, which has a great impact on the growth of later crops and the types of soil ...
