Compound trace element fertilizer

Abstract

The invention aims at providing a compound trace element fertilizer and relates to a fertilizer. Various trace elements needed by human bodies are added in the compound trace element fertilizer so as to directly act on or enter crops, and then the human bodies can be appropriately supplemented with desired nutrients by ingesting agricultural products. According to the technical scheme: the compound trace element fertilizer is prepared by mixing the following ingredients in parts: 3-5 parts of boric acid, 2-5 parts of sodium selenite, 20-25 parts of ferrous sulfate, 5-8 parts of zinc sulfate, 8-15 parts of copper sulfate, 8-18 parts of ammonium molybdate and 60-80 parts of stuffing algas. In the technological scheme, the sodium selenite is substituted with sodium selenate, the zinc sulfate is substituted with zinc chloride, the boric acid is substituted with borax, the ammonium molybdate is substituted with sodium molybdate and the ferrous sulfate is substituted with ferric sulfate.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a trace element fertilizer in which trace elements are compounded into the fertilizer. Background technique [0002] The growth of crops not only needs the three elements of N, P, and K, but also a variety of other nutrients. Experiments have shown that trace elements (B, Zn, Mn, Fe, Cu, Mo) are also nutrients for crop growth. Although their demand is not large, they play a positive role in the growth and development of various crops, and have obvious effects of increasing yield and further improving the quality of crops. With the development of agricultural production, crop varieties are constantly updated, the nutrients that crops need to supplement also increase, and the use of trace elements also increases. People's living standards are improving year by year, and the human body needs to supplement 70-80% of the nutrients % needs to be absorbed from food. There is no product added to fertili...
