Preparation method for charcoal base fertilizer

Abstract

The invention discloses a preparation method for a charcoal base fertilizer. The method mainly includes: subjecting wheat straw to crushing, drying, mixing and other steps to obtain biological ash, subjecting the biological ash to sieving treatment, then stirring 15-18 parts of ammonium sulfate, 9-12 parts of urea, 6-8 parts of potassium sulfate, 1-2 parts of monoammonium phosphate, and 9-13 parts of bentonite, and finally carrying out granulation, thus obtaining fertilizer granules. By using wheat straw as raw materials, on the one hand pollution caused by straw burning can be prevented, and on the other hand straws can be utilized.

Description

technical field [0001] The invention relates to a method for preparing a fertilizer, in particular to a method for preparing a carbon-based fertilizer. Background technique [0002] The disposal of straw plants has always been concerned by people. How to solve this problem has always been an important topic of concern to people. Although incineration is a good method, although it is convenient to plant the next season of crops after straw incineration, returning straw to the field will naturally make the soil Contains a large amount of carbon element. However, after burning, many nutrients are lost, and at the same time, the soil organic matter is lost, and a little ash that is added is often scattered with the wind. At present, there is a better treatment method, which is to directly spray the pesticide that promotes straw rot, and use a rotary tiller to crush and cover the straw, but this method cannot effectively solve the straw problem.

Problems solved by technology

However, after burning, many nutrients are lost, and at the same time, the soil organic matter is lost, and a little bit of ash is often scattered with the wind.

Now there is a better treatment method, which is to directly spray the pesticide that promotes straw rot, and use a rotary tiller to crush and cover the straw, but this method cannot effectively solve the straw problem.
