Problems solved by technology

[0002] Plant ash refers to the ashes of herbaceous and woody plants after burning. It contains mineral elements contained in plants. Among them, the most abundant is 6-12% potassium, and more than 90% of these potassium components are water-soluble. Potassium carbonate (K2CO3) It exists in form, because of its light weight, it is not easy to spread in powder form, it is easy to go with the wind when it is dry, and it is easy to go with water when it is wet; the pH value is 9 and it is alkaline, which is easy to make the soil alkaline, and it is easy to contact with nitrogen fertilizer. Cause nitrogen volatilization and loss, corrode organic fertilizer and other dung; and because of its single nutrition, it is difficult to meet the needs of crops, a large amount of plant ash is produced every year in our country, only a small amount is used in agriculture, and most of them are thrown away with garbage. Occasionally, in windy days, become the chief culprit of environmental pollution

Abstract

The invention a method for preparing a plant ash saturated aqueous solution and application thereof. The method comprises the following steps of: carrying out the procedures, such as dissolution, solid-liquid separation, and the like on plant ash to prepare a plant ash saturated aqueous solution; and further preparing a potassium fertilizer particle or purifying by utilizing the plant ash saturated aqueous solution. The method is simple and easy and has low cost, the prepared potassium fertilizer is easy for storage and application and can be used for compounding other fertilizers, and the particle has potassium content more than 10 percent, nitrogen content more than 3 percent and a pH value 5-7, can coexist with ammonium nitrogen, is an ecological type fertilizer, contains all secondary trace elements needed by crops and can remove various damages brought by using chemical fertilizers in excess for many years, such as quality reduction of agricultural products, soil hardening, great popularity of disease and insect pest, and the like; and the potassium carbonate prepared by purification has high purity and can be further used for preparing other agricultural fertilizers.
