Problems solved by technology

The absorption of potassium by corn increases rapidly after jointing in spring and summer, and reaches the peak at the flowering stage. The absorption rate is high, which may easily lead to insufficient potassium supply and potassium deficiency symptoms

Abstract

The invention relates to the field of fertilizers and particularly relates to a fertilizer for corn planting. The fertilizer is prepared from the following ingredients in parts by weight: 20-25 parts of straws, 10-20 parts of sawdust, 10-12 parts of expansible perlite powder, 1-2 parts of nitrification inhibitor DMPP, 0.3-0.5 part of tea saponin, 100-105 parts of ammonium sulfate, 199-209 parts of urea, 68-78 parts of monoammonium phosphate, 95-105 parts of calcium superphosphate, 5-15 parts of calcium magnesium phosphate fertilizer, 279-289 parts of potassium chloride, 10-20 parts of molybdenum, zinc, manganese, boron and ferrum amino-acid chelate (complex), 95-105 parts of nitrohumic acid, 45-55 parts of amino acid, 18-28 parts of biological preparation and 7-17 parts of synergist. According to the fertilizer, major elements, i.e., nitrogen, phosphorus and potassium and minor elements such as boron and molybdenum are reasonably matched, so that slow acting and fast acting are combined; and an organic fertilizer and a special fertilizer or chemical fertilizer are applied after being mixed, so that flowers and fruits can be reserved, the yield is increased, and obtained corn is rich in amino acids, vitamins, proteins, vegetable oil, lignin, minor elements and oxidation resisting substances.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a fertilizer for corn planting. Background technique [0002] Maize is an annual plant of Gramineae, and it is widely planted in my country. The north is the spring sowing corn area, which accounts for 30% of the country's corn planting area, and the total output accounts for about 35% of the country's total. The Huang-Huai-Hai Plain is a summer corn area, accounting for 38% of the country's corn planting area, and its total production accounts for about 50% of the country's total. The northwest irrigated corn area accounts for about 6% of the country's planted area. [0003] Fertilizer characteristics of corn [0004] Studies from various places have shown that for every 1000 kg of corn grains produced, the absorption ratio of nitrogen, phosphorus, and potassium in spring corn is about 1: 0.3: 1.5, and it needs to absorb 35-40 kg of nitrogen (N), 12-14 kg of phosphorus (P2O5), and ...
