Abstract

The invention discloses a special fertilizer for corn. The special fertilizer for corn is prepared from raw materials in parts by weight as follows: 35-40 parts of a humic acid coated fertilizer, 43-48 parts of manure of poultry and livestock, 50-60 parts of corn straw, 22-25 parts of a shrimp peptide amino acid organic fertilizer, 3-6 parts of light calcium carbonate powder, 4-8 parts of zeolite powder, 2-5 parts of calcium bentonite, 1-3 parts of dolomite, 15-20 parts of urea, 10-13 parts of urea phosphate, 8-12 parts of potassium sulfate, 0.5-0.9 parts of zinc sulfate, 0.3-0.6 parts of molybdenum sulfate, 0.2-0.4 parts of boron sulfate, 0.8-1.2 parts of manganese sulfate, 15-20 parts of paraffin and 10-14 parts of coating resin. The invention further provides a preparation method of the special fertilizer for corn. The prepared special fertilizer for corn belongs to a blended type controlled-release fertilizer, can release fertility in the whole growth period of corn and can meet requirements of corn for nutrients in the whole growth period after being applied once, the cultivation difficulty of corn is reduced, the labor cost is saved, the production efficiency is improved, and the agricultural modernization level is further improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for corn and a preparation method thereof. Background technique [0002] Corn is one of the most widely distributed food crops in the world. Its planting area is second only to wheat and rice and ranks third. The planting range is from 58° north latitude (Canada and Russia) to 40° south latitude (South America). The famous corn golden belts are located in the United States and China. China is the world's second largest corn producer and also the world's second largest consumer. China's annual corn production ranks second in the world, followed by Brazil, Mexico, and Argentina. Corn originates in Central America and is the main food crop. It likes high temperature and was introduced to China in the Ming Dynasty in the 16th century. Corn is sown in a large area and widely distributed in China. [0003] In recent years, in order to meet the needs of corn planting, t...
