Embodiment 1

[0036] Weigh 700kg tobacco rod, add water to make the moisture content of the tobacco rod reach 60%; take 14kg of urea and mix evenly with the tobacco rod; take 28kg of fulvic acid, 4 times the water to dissolve, adjust the pH value to 8.5 with potassium hydroxide, and mix with the tobacco rod Mix evenly; take 300kg of selenium ore powder and mix it evenly with tobacco stems; inoculate the raw materials with 1L of activated and cultured fermentation broth; pile the inoculated raw materials and cover with plastic film for fermentation; turn the pile once every 2 days, A total of 5 times, and then stacking and fermentation for 28 days; the fertilizer is dried until the moisture content is 17%-18%. The sample package is 40kg / bag.

[0037] The selenium ore powder is crushed and ball milled to a particle size of less than 0.15 mm to prepare selenium ore powder with a selenium content of not less than 180 mg / kg, and the water-soluble selenium content is 37.4 mg / kg.

Abstract

The invention relates to a selenium-enriched organic fertilizer of a tobacco stem. The selenium-enriched organic fertilizer is characterized by comprising the following operation steps of: a, preparing raw materials; b, fermenting; and c, carrying out drying treatment. The selenium-enriched organic fertilizer of the tobacco stem disclosed by the invention utilizes the tobacco stem, activated selenium ore powder, fulvic acid and urea to simply produce the selenium-enriched organic fertilizer, and effectively solves the reutilization problem of the tobacco stems. The technical keys are that the selenium ore powder which is crushed until the grain diameter is less than 0.15mm and and a fulvic acid solution with the pH (Potential of Hydrogen) value which is adjusted to 8.5 are utilized and tobacco stem powder is used as a raw material; and the urea and self-made zymophyte liquid are matched to produce the selenium-enriched organic fertilizer.

Description

Technical field [0001] The invention relates to a selenium-enriched organic fertilizer for tobacco stems. Background technique [0002] China is rich in selenium resources, and its industrial reserves rank fourth in the world. However, due to the uneven distribution of selenium resources, 72% of my country's regions are in a selenium-deficient and low-selenium ecological environment. Among them, from the three northeastern provinces to the Yunnan-Guizhou Plateau, about 2 / 3 of the main crops contain less than selenium. 0.05mg / kg, an internationally recognized selenium deficiency area. In 2011, my country’s tobacco planting area was 18.58 million mu, and most of the tobacco areas were deficient in selenium. Smoking is harmful to health. Increasing the selenium content of tobacco leaves can effectively reduce the content of major harmful components such as cigarette tar toxicity and free radicals, and reduce the harm of smoking to the human body to a certain extent. Therefore, the...
