Problems solved by technology

Therefore, if the zinc nutrient element cannot be supplemented in time on the zinc-deficient soil, it will seriously affect the yield and quality of crops.
However, in high-phosphorus liquid fertilizers, zinc can easily form insoluble precipitates with phosphorus.

Abstract

The invention provides a suspended liquid compound fertilizer and a preparation method thereof. The fertilizer comprises 10-15 parts of a zinc fertilizer, 1-2 parts of a magnesium fertilizer, 20-30 parts of phosphoric acid, 2-4 parts of urea phosphate, 2-4 parts of ammonium polyphosphate, 25-35 parts of composted excrements of livestock and 40-60 parts of suspending agent mother liquor, wherein the suspending agent mother liquor is prepared from 10-15 parts of hydroxyethyl cellulose, 5-10 parts of silicon dioxide and 20-25 parts of water. The preparation method comprises the following steps of: adding the zinc fertilizer into the suspending agent mother liquor and uniformly stirring to obtain a slurry suspended liquid; then adding phosphoric acid at 75-85 DEG C; adding ammonium nitrate, urea phosphate and ammonium polyphosphate at 50-60 DEG C; and finally, adding the magnesium fertilizer and the composted excrements of livestock to obtain the suspended liquid compound fertilizer. The compound fertilizer has the advantages of good uniformity and good suspending property, and can effectively prevent symptoms such as zinc deficiency while meets the growth demands of crops.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a suspension type liquid compound fertilizer and a preparation method thereof. Background technique [0002] With the development of modern facility agriculture, the promotion and application of pipeline fertilization technology, drip irrigation and sprinkler irrigation and fertilization technology have begun to popularize in our country, and the application of this technology must be realized by dissolving fertilizer in water, and more and more farmers are giving crops In the process of topdressing, the fertilizer is also applied after dissolving it in water. [0003] At the same time, compound fertilizers are being used more and more widely. However, due to technical limitations, most of the compound fertilizers produced by domestic manufacturers are in solid form, and the existing compound fertilizers are all in granular form for spreading. . Farmers find tha...
