Tobacco biomass charcoal based long-effect potassium fertilizer and preparation method of tobacco biomass charcoal based long-effect potassium fertilizer

Abstract

The invention discloses a tobacco biomass charcoal based long-effect potassium fertilizer and a preparation method of the tobacco biomass charcoal based long-effect potassium fertilizer. The tobacco biomass charcoal based long-effect potassium fertilizer is prepared from the following raw materials: 25 to 35 parts of tobacco biomass charcoal, 35 to 45 parts of a silicon potassium calcium magnesium fertilizer, 10 to 20 parts of potassium chloride, 5 to 10 parts of potassium humate and 5 to 10 parts of a granulation binder and the balance of water, wherein the tobacco biomass charcoal is prepared by carrying out thermal cracking on waste tobaccos for 1.5h to 2.5h through a portable carbonization furnace under an anaerobic condition at 450 DEG C, and cooling. The tobacco biomass charcoal based long-effect potassium fertilizer has the effects and potentials of improving physicochemical characters and microorganism activity of soil and increasing the carbon sequestration potential of the soil, can be used for increasing the organic matters of the soil, the soil cation exchange capacity and the granular structure, and has the effects of preventing the soil from being hardened, improving hydrothermal conditions of the soil, effectively adjusting a soil structure and preventing the soil from degradation; a positive cycle of agricultural production is realized.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a smoke biomass charcoal-based long-acting potassium fertilizer and a preparation method thereof. Background technique [0002] Potassium is one of the nutrient elements necessary for crop growth. Long-term insufficient supply (input) of potassium in the soil will affect the normal growth of crops, increase yield, and improve quality. Especially for vegetable crops, the amount of potassium required ranks first among the three elements. The long history of farming has made my country's main cultivated land in a state of extreme poverty for a long time, and the only way to supplement nutrients is through fertilization. For a long time, people have generally paid attention to nitrogen and phosphorus fertilizers and neglected potassium fertilizers. With the improvement of agricultural production levels, the input of organic fertilizers has decreased, and the input of...
