Abstract

The invention provides slow-release fluid suspension composite fertilizer. The slow-release fluid suspension composite fertilizer comprises 30-200 parts of fertilizer nutrients, 0.05-2 parts of a thickening agent, 0.1-4 parts of a suspending agent, 0.1-3 parts of an emulsifier, 0.05-1 part of a nitration inhibitor and 0-15 parts of water. The fertilizer nutrients comprise nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, humic acid and trace elements and also contain at least one quick-acting fertilizer and at least one slow-release fertilizer. The invention also provides a preparation method and a use method of the slow-release fluid suspension composite fertilizer. The slow-release fluid suspension composite fertilizer has the advantages of the existing fluid suspension and is ternary liquid fertilizer containing the quick-acting and slow-acting nutrients, trace elements and humic acid, prolongs fertilizer efficiency of the suspension fertilizer, realizes combination of trace elements, humic acid and fertilizer, continuously and stably provides nutrients needed by crop growth and development, and solves the problems of nutritional deficiency symptom and later fertilizer removal in crop growth.

Description

technical field [0001] The invention belongs to the technical field of liquid fertilizer production, and in particular relates to a slow-release suspension liquid compound fertilizer and a preparation method and application method thereof. Background technique [0002] With the rapid development of water and fertilizer integration technology in my country, the development trend of instant, compound, liquid, concentrated and slow-acting fertilizers is becoming more and more obvious. In some agricultural developed countries, such as the United States, Israel, Australia, Canada, etc., liquid compound fertilizers are mainly used, and the proportion of liquid compound fertilizers is still increasing year by year. Liquid fertilizer is a kind of fluid water-soluble fertilizer. It is more and more accepted by people because of its uniform composition, high nutrient activity, flexible formula, simple production, convenient use, and wide source of raw materials. Liquid fertilizer, al...
