The invention provides a selenium-enriched trace element fertilizer, relating to a selenium-enriched fertilizer. The invention aims to provide the selenium-enriched trace element fertilizer added with selenium by a mode of a trace element. The invention adopts the technical proposal that: the selenium-enriched trace element fertilizer comprises the following compositions in percentage by weight: 0.8 to 1 percent of a raw material containing trace element selenium, 8 to 10 percent of raw material containing trace element boron, 8 to 10 percent of raw material containing trace element zinc, 4 to 6 percent of raw material containing trace element manganese, 4 to 6 percent of raw material containing trace element copper, 4 to 6 percent of raw material containing trace element molybdenum, 28 to 35 percent of raw material containing trace element iron, and 30 to 35 percent of filled auxiliary material. The selenium-enriched trace element fertilizer is mainly applied to production of fertilizer containing selenium.
Description
technical field [0001] The invention relates to a selenium-enriched fertilizer, in particular to a selenium-enriched trace element fertilizer added with selenium in the form of trace elements. 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. However, ...
