Compound fertilizer, preparation method and application of compound fertilizer

Abstract

The invention provides compound fertilizer, a preparation method and an application of the compound fertilizer and relates to the technical field of fertilizer. The compound fertilizer is mainly prepared from components in parts by weight as follows: 30-50 parts of inorganic nitrogenous fertilizer, 20-40 parts of inorganic phosphorus fertilizer, 20-35 parts of inorganic potassic fertilizer, 5-8 parts of trace element fertilizer, 4-6 parts of potassium fulvate, and 0.8-1.2 parts of a nitrogen regulator, wherein the nitrogen regulator contains a nitrification inhibitor. The technical problems that the conventional fertilizer is low in utilization rate, has an obvious nitrification effect and can produce bad influence on soil and crops when used for a long time, and quality of agricultural products can be reduced due to environmental pollution and damage to soil structure and ecology by over-fertilization are solved. With potassium fulvate and the nitrogen regulator added, the compound fertilizer has the advantages that soil nutrients can be perfected effectively, the soil structure can be improved, the nitrification effect can be inhibited, and after the fertilizer is applied, the ecological environment of the soil is optimized and the quality of the agricultural products is improved.

Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer, a preparation method and an application thereof. Background technique

[0002] With the continuous improvement of production levels, people's desire for a pollution-free ecological environment and the demand for green products will definitely promote the transformation of traditional agriculture into ecological agriculture. Plants are fertilized with nitrogenous nutrients, simply incorporating various nitrogenous components into the soil is inefficient and can be detrimental, growing plants often cannot absorb the nitrogen provided in sufficient quantities, and the applied nitrogen may pass through Loss by various mechanisms such as volatilization, leaching, hydrolysis and nitrification. When soil is added with ammoniacal nitrogen, which undergoes nitrification, soil bacteria including Nitrosomonas convert ammonium into nitrate, so if ammoniacal nitrog...
