Soil improvement organic biological fertilizer and preparation method thereof

Abstract

The invention discloses soil improvement organic biological fertilizer and a preparation method thereof. The soil improvement organic biological fertilizer comprises the following raw materials in parts by weight: 30 to 35 parts of rice straws, 25 to 30 parts of animal dung, 20 to 25 parts of charcoal, 10 to 15 parts of bean pulp, 5 to 10 parts of diatom ooze, 2 to 2.5 parts of soddy soil, 2 to 3 parts of zeolite powder, 3 to 4 parts of a microbial agent, 2 to 3 parts of sodium benzoate, 2 to 3 parts of monoammonium phosphate, 2 to 3 parts of mugwort, 2 to 2.5 parts of licorice, 1 to 2 parts of calcium chloride, 1 to 2 parts of amino acid, 1 to 2 parts of starch, 1 to 2 parts of molasses powder, and 1 to 2 parts of humic acid. The soil improvement organic biological fertilizer takes plant waste as the raw material, not only is beneficial to improve the soil quality, but also can reduce the production cost, thereby improving the physicochemical property of soil, comprehensively improving the soil structure, and enabling the soil quality to achieve the effects of softness, permeability, moisture holding and fertilizer maintenance, and optimizes the composting process by preferentially selecting organic waste converted products capable of passivating heavy metal and enhancing the fertilizer efficiency of organic fertilizer, such as charcoal, biological humic acid of and the like, as compost base materials, so as to achieve the purpose of producing environmental high-quality organic fertilizer.

Description

technical field [0001] The invention relates to the field of organic fertilizers, more specifically, the invention relates to a soil-improving compound organic biological fertilizer and a preparation method thereof. Background technique [0002] In order to increase the yield, people will apply a large amount of fertilizer when planting, and fertilization every year will inevitably lead to poorer soil quality, problems such as hardening, poor air permeability, and serious lack of nutrition, and the planting yield is getting lower and lower. The quality is also getting worse. And with the improvement of people's living standards, people began to pay attention to green food. How to effectively improve poor-quality soil and make full use of limited land resources is a major problem that needs to be solved urgently in agricultural production, ecological construction and environmental protection. Applying soil amendments is one of the important measures to restore degraded soil. ...
