Abstract

The invention discloses a high-nitrogen organic suspension liquid compound fertilizer and a preparation method thereof. The high-nitrogen organic suspension liquid compound fertilizer comprises the following components by weight part: 10-17 parts of suspending agent mother liquid and 90-83 parts of nitrogenous fertilizer, phosphate fertilizer, potassium fertilizer, humic acid and trace elements; the suspending agent mother liquid comprises the following components by weight part: 2-7 parts of hydroxyethylcellulose, 1-5 parts of sodium bentonite and 6-10 parts of water. The fertilizer of the invention has good stability and uniformity and can simultaneously supply macro-elements, trace elements and organic nutrients for crops, so that the crops can absorb the macro-elements and simultaneously supplement the trace elements, and the nutrient utilization ratio is high. Because of the complete solubility and the high nutrient content of the fertilizer, the fertilizer facilitates the use ofpeasants, and the labor and the fertilizer cost are saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a large-scale and medium-trace element fertilizer applied to crops, in particular to an organic suspension type liquid compound fertilizer with high nitrogen content and a preparation method thereof. Background technique [0002] More and more farmers are used to dissolving fertilizer in water and applying it in the process of topdressing crops. With the development of modern facility agriculture, the popularization and application of pipeline fertilization technology, drip irrigation and sprinkler irrigation and fertilization technology have begun to popularize in our country. The application of this technology must be realized by dissolving fertilizer in water. [0003] At the same time, with the promotion of balanced fertilization and formula fertilization technology, compound fertilizers have been more and more widely used. However, due to technica...
