Soil improvement type straw compound organic fertilizer and preparation method of soil improvement type straw compound organic fertilizer

Abstract

The invention provides a soil improvement type straw compound organic fertilizer and a preparation method of the soil improvement type straw compound organic fertilizer. The soil improvement type straw compound organic fertilizer is prepared from the following raw materials in parts by weight: 30 to 35 parts of rice straw, 25 to 30 parts of animal excrement, 20 to 25 parts of biological charcoal, 10 to 15 parts of soybean meal, 5 to 10 parts of cassava residue, 5 to 10 parts of diatom ooze, 2 to 2.5 parts of plant ash, 2 to 2.5 parts of turfy soil, 2 to 3 parts of zeolite powder, 3 to 4 parts of a microorganism bacterium agent, 2 to 3 parts of sodium benzoate, 2 to 3 parts of ammonium monohydrogen phosphate, 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 type straw compound organic fertilizer takes plant wastes as raw materials; the quality of soil can be easily improved and the production cost can also be reduced, so that the physicochemical properties of the soil are improved, and the structure of the soil is comprehensively improved, and furthermore, the soil quality has the effects of softness, air permeability, water retention and fertilizer conservation; the aim of producing an environment-friendly high-quality organic fertilizer through preferably selecting heavy metal capable of being passivated, the biological charcoal capable of improving the fertilizer efficiency of the organic fertilizer, and conversion products of organic wastes including the biological humic acid and the like as composting base materials, and optimizing a composting process.

Description

technical field [0001] The invention relates to the field of organic fertilizers, more specifically, the invention relates to a soil-improving straw compound organic 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. Soil...

[0004] Agricultural pollution has become the largest environmental pollution in our country. The content of organic matter in soil in our country has been reduced from 7%-11% in the early days of the founding of the People's Republic of my country to below 3%. Vicious circle and irreparable loss

Every year in the busy season of summer harvest and autumn, the use efficiency of organic resources such as straw is very low, and it is often solved by simple and trouble-free burning, which burns the surface of the soil, wastes resources, and pollutes the air; excessive use of chemical fertilizers, undecomposed and plant waste The unabsorbed nutrients are washed by rain and flow into rivers and lakes, resulting in excess nutrients in water quality and serious pollution; the extensive use of chemical fertilizers and pesticides pollutes agricultural products, leaving hidden dangers for human survival and life; It can add enough nutrients to the soil, but ignores the supply of organic matter. If chemical fertilizers are used alone for a long time, the soil will have a negative impact on soil quality and the environment. In the absence of sufficient organic matter, the soil aggregate structure is difficult to form. The adhesion between soil particles is weakened, which in turn reduces the water and fertilizer retention capacity of the soil
