Abstract

The invention discloses a selenium-rich organic fertilizer.The selenium-rich organic fertilizer is mainly prepared from, by weight, 70-90 parts of chicken manure, 30-42 parts of sheep manure, 20-28 parts of pond sludge, 5-8 parts of gecko manure, 4-7 parts of pangolin manure, 35-50 parts of fiber-containing biomass, 30-35 parts of bean pulp, 10-15 parts of fishbone, 3-6 parts of black peanut shells, 5-8 parts of a strain, 20-26 parts of potassium humate and 20-30 parts of activated selenium ore powder.A production method of the selenium-rich organic fertilizer includes the following steps that 1, fishbone powder, bean pulp, black peanut shells, fiber-containing biomass and the strain are subjected to primary fermentation; 2, a KOH solution is added to regulate the PH after primary fermentation, and then potassium humate, part of activated selenium ore powder, chicken manure, sheep manure, pond sludge, gecko manure and pangolin manure are added and subjected to secondary fermentation; 3, the rest of activated selenium ore powder is added after secondary fermentation.By applying the organic fertilizer, the selenium content in crops can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a selenium-enriched organic fertilizer and a preparation method thereof. Background technique [0002] Selenium is an indispensable trace element for the human body, and it is a powerful antioxidant that can effectively remove carcinogenic factors - free radicals, and has the reputation of "the king of anti-cancer". Scientists have investigated the relationship between cancer mortality and selenium intake per person in 20 countries and found that if selenium intake is low, the incidence and mortality of cancer will increase, especially colon cancer, pancreatic cancer, and ovarian cancer. , prostate cancer and male lung cancer and skin cancer are the most obvious. According to statistics, there are 42 countries and regions in the world who are deficient in selenium; a survey conducted by the Chinese Nutrition Society shows that about 700 million people in two-thirds of my cou...
