Problems solved by technology

[0005] The demand for organic liquid fertilizers in my country is very large, but the research on liquid fertilizers in my country has been in a relatively backward state, and there are very few compound fertilizers in liquid form. Although some manufacturers can produce liquid fertilizers, these liquid fertilizers have low nutrient content variety, also increases the transportation cost

Abstract

The invention discloses an organic liquid compound fertilizer and a preparation method thereof. The organic liquid compound fertilizer consists of the following components in part by mass: 30 to 40 parts of suspending agent mother liquor and 60 to 70 parts of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and trace elements, wherein the suspending agent mother liquor comprises 25to 32 parts of waste alcohol, 1 to 2 parts of carboxymethylcellulose sodium, 1 to 2 parts of xanthan gum, 1 to 2 parts of sodium pyrophosphate and 1 to 2 parts of attapulgite. The organic liquid compound fertilizer has the advantages of good stability and homogeneity, capability of simultaneously providing organic nutrients and trace elements for crops, convenient use and low preparation cost.

Description

technical field [0001] The invention relates to the field of preparation of organic fertilizers, in particular to an organic 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, with the promotion of balanced fertilization and formula fertilization technology, compound fertilizers are more and more widely used. However, due to technical limitations, most of the compound fertilizers produced by domestic manufacturers are in solid form. All compound fertilizers a...
