Abstract

The invention relates to a buffering harmless plant ash compound fertilizer and a preparation method thereof. The buffering harmless plant ash compound fertilizer is a solid or liquid fertilizer taking plant ash as a main raw material and further comprises the following preparation raw materials by weight: 10-40 parts of humic acid, peat, biochemical fulvic acid or potassium fulvic, 0-20 parts of non-metal nano mineral material, 0-20 parts of chitin or chitosan and 0-10 parts of seaweed extractive, wherein the amount of plant ash is 0.7-2 times the total amount of the raw materials. According to different soil characteristics, plant ash is taken as the main material and is mixed with humic acid, non-metal nano mineral material, chitin, seaweed extractive, amino acid and other substances to prepare the solid or liquid fertilizer, which is used as a base fertilizer or additional fertilizer, has the performance of passivating heavy metals in soil, can reduce the enrichment amount of heavy metals (such as mercury, chromium, lead, arsenic and nickel) in soil, ensures the safety of agricultural products and has the effects of improving soil and promoting growth of plants.

Description

technical field [0001] The invention relates to a buffered and harmless plant ash compound fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Fertilizer is the food for the growth of various plants. In addition to providing various nutrients necessary for plant growth, it can also improve the soil. Reasonable fertilization is an important measure to increase crop yield. In recent years, with the increase in the application of chemical fertilizers, there is a tendency to focus on output rather than input, re-use land rather than cultivated land, and chemical fertilizers rather than organic fertilizers. This tendency makes a large amount of ammonium chloride, ammonium sulfate, nitric acid After ammonium, potassium nitrate, potassium sulfate, potassium chloride and other chemical fertilizers are applied to the soil, under the action of cation exchange in the plant roots, the plants replace the ammonium ion...
