Abstract

The invention relates to a chemical fertilizer special for corns. The chemical fertilizer comprises the following raw materials in parts by weight: 10 to 20 parts of urea, 5 to 10 parts of hydroxypropyl methyl cellulose, 15 to 25 parts of diammonium phosphate, 15 to 20 parts of potassium chloride, 5 to 10 parts of kieselguhr, 2 to 5 parts of calcium sulfate, 3 to 8 parts of chelated zinc, 1 to 4 parts of ferrous sulfate and 1 to 3 parts of phoxim. The chemical fertilizer can be used for providing various nutrients for the corns in a growing process and providing various trace elements and nutrient substances at the same time, so that various nutrient elements are absorbed by the corns while the corns grow rapidly.

Description

technical field [0001] The invention relates to a special chemical fertilizer for corn. Background technique [0002] Corn is a crop that needs more nitrogen, and it needs sufficient nitrogen fertilizer supply to obtain higher yields. At present, the nitrogen-rich fertilizers that are easy to use are mainly organic polymer coated fertilizers. However, the use of organic polymer coated fertilizers, on the one hand, has a higher cost of use, and on the other hand, because it cannot be degraded, it will cause corresponding pollution. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a special fertilizer for corn that can reduce the use cost. [0004] The technical solution of the present invention to solve the above technical problems is as follows: a special fertilizer for corn, comprising the following raw materials in parts by weight: 10-20 parts of urea, 5-10 parts of hydroxypropyl methylcellulose, 15-25 parts of diammo...
