Fertilizer containing power plant ash and preparation method thereof

Abstract

The invention discloses a fertilizer containing power plant ash and a preparation method thereof. The invention is characterized in that the fertilizer is prepared from the following components in parts by weight: 300-500 parts of power plant ash, 25-30 parts of phosphogypsum powder, 150-200 parts of wood meal, 150-200 parts of grass meal, 100-150 parts of kieselguhr, 60-80 parts of ammonium chloride, 50-65 parts of zeolite, 100-180 parts of corn straw, 25-30 parts of ferrous sulfate, 40-60 parts of potassium chloride, 30-45 parts of magnesium oxide, 15-45 parts of kaolin, 20-30 parts of borax, 50-60 parts of starch and 6-8 parts of soil conditioner. By using the power plant ash as the potassium source of the fertilizer, the fertilizer has the advantages of balanced proportions of N, P and K and comprehensive and balanced fertility, has an obvious promotion action on the growth of crops, and improves the yield and quality of the crops. The soil improver contains bowlder which contains abundant microelements beneficial to the human body, and the microelements are absorbed by the crops and converted through the food chain so as to be beneficial to the human body; and meanwhile, the adsorption component can effectively adsorb and cure toxic heavy metal elements in soil, and reduce the heavy metal elements absorbed by the crops. The fertilizer can enhance the crop yield.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a fertilizer containing power plant ash and a preparation method thereof. Background technique [0002] Agriculture is the foundation of other industries such as industry and service industry. The rise and fall of agriculture is a major event that directly affects the national economy and people's livelihood. At present, the world is facing severe problems of population increase and environmental degradation. As a country with a large population and a large agricultural country, this problem is particularly prominent. One of the main reasons for this situation is the extensive use of inorganic fertilizers. The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce ...

AI Technical Summary

Problems solved by technology

The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce the soil quality; 3. 1. Due to the decline of soil quality, the buffering capacity is greatly reduced, and the use of inorganic fertilizers is difficult to achieve results and is likely to cause fertilizer damage; 4. Due to the imbalance of nutrients, the disease resistance of the crops used is reduced; 5. During the production and use of inorganic fertilizers, there will be The environment causes a lot of pollution and wastes a lot of resources; 6. It makes agricultural production fall into a vicious circle and it is difficult to achieve sustainable development
