Problems solved by technology

Under the condition of more precipitation, strong leaching occurs in acidic soil, resulting in K + , Ca 2+ , Mg 2+ A large number of mineral nutrient ions are leached out, which seriously affects the growth of crops
Acidic soil will also increase the solubility of aluminum and form aluminum compounds that can be absorbed by plants. Excessive absorption of aluminum by plants will reduce the quality of crops
In addition, acidic soil will also increase the concentration of heavy metal ions in the soil, intensify pests and diseases, and the cultivation conditions will be lost when the soil is severely acidified
At present, there are organic fertilizers that adjust soil pH by adding trace elements in China, but they are all added in the form of simple inorganic salts. When inorganic salts enter the soil, they dissolve in water and become ionic, and react with phosphate in the soil to form water-insoluble substances. Loss of activity, therefore, it is difficult to effectively improve the acidic soil environment

Abstract

The invention belongs to the technical field of an organic fertilizer, and particularly relates to an organic fertilizer suitable for acidic soil, and a preparation method thereof. The organic fertilizer comprises the following raw materials in percentage by weight: 15 to 30 percent of silicon humate, 20 to 30 percent of biological carbon black, 20 to 30 percent of water-quenched slag, 20 to 30 percent of an organic fertilizer, 2 to 5 percent of an amino acid micro-element fertilizer and 0.1 to 0.5 percent of BMC composite biological bacteria. The organic fertilizer provided by the invention not only can improve the acidic soil environment, but also can improve the fertilizer effect and the activity of soil.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to an organic fertilizer suitable for acidic soil and a preparation method thereof. Background technique [0002] Acidic soil is a general term for soil with low pH value, including red soil, yellow soil, brick red soil, red soil and podzol. Due to the excessive use of chemical fertilizers, the soil in my country, especially in the south, has been acidified in a large area. Under the condition of more precipitation, strong leaching occurs in acidic soil, resulting in K + , Ca 2+ , Mg 2+ A large number of mineral nutrient ions are leached and lost, which seriously affects the growth of crops. Acidic soil will also increase the solubility of aluminum and form aluminum compounds that can be absorbed by plants. Excessive absorption of aluminum by plants will reduce the quality of crops. In addition, acidic soil will also increase the concentration of heavy m...
