Abstract
The invention discloses a core compound fertilizer with high use rate. The core compound fertilizer is prepared from the following raw materials: ammonium nitrate, dicalcium phosphate, potassium sulphate, tea seed cake, yeast protein, cottonseed meal, biogas residue, wormcast, seabird excrement, humic acid, talcum powder, medical stone powder, vermiculite power, expanded perlite and coal ash. The core compound fertilizer with high use rate provided by the invention has the advantages that the nutrient release period is matched with the corn nutrition absorbing rule, the cost is low, the soil can be improved, the topdressing is not required after once fertilization, the fertilizer loss is reduced, the use rate of the fertilizer is increased and the environment is not damaged.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a corn compound fertilizer with high utilization rate. Background technique [0002] Corn is also known as maize, corn, corn, and cob. It is called corn in Cantonese and fanmai in Hokkien. It is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world. Zeatin has the reputation of longevity food, rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides, etc., and has great potential to develop high nutrition and high biological function food. Corn is not only the main source of food for human beings, but also a popular health food, which often appears on the dining table and is popular in the European and American world, which was once known for its fine food. Therefore, the demand for corn is very high. But along with the raising of people's living standard, g...
