Fertilizer applied to corn field

Abstract

The invention provides a fertilizer applied to a corn field. The fertilizer is prepared from the following raw materials in percentage by weight: 26%-32%% of large granular urea, 5%-12% of granular ammonium, 12%-21% of granular phosphorus fertilizer, 3%-6% of a potassium fertilizer and 24%-38% of an aojia mixed fertilizer. The fertilizer applied to the corn field disclosed by the invention has the advantage that the fertilizer with the same content and the same formula can be used for increasing the yield of the corns by 30%-50% according to contrast experiment, and the fertilizer has a short-term effect and a long-term effect by being applied once, is labor-saving, time-saving, money-saving and environmentally friendly.

Description

technical field [0001] The invention relates to a compound fertilizer for production, in particular to a fertilizer applied to cornfields. Background technique [0002] Corn is one of the three major food crops in the world. In my country, the output of corn has ranked first among the three major food crops. This has important strategic significance for ensuring my country's food security. Corn is not only an important food crop, but also an important feed crops, medicinal and energy crops. Corn plants are tall, with thick leaves and well-developed root system. They have a large demand for nitrogen, phosphorus and potassium nutrients throughout their life, especially for nitrogen. Nitrogen is not only an important living substance such as corn protein and chlorophyll, but also a decisive factor affecting the photosynthesis of corn. , corn is sensitive to nitrogen fertilizer, and nitrogen application can increase the yield of corn significantly. At the same time, reasonable ...

Problems solved by technology

[0003] However, in order to achieve high yield of corn, sufficient fertilizer must be topdressed at the seedling stage, jointing stage, trumpet stage, and filling stage, and topdressing fertilizer at the late growth stage of corn is extremely inconvenient, labor-intensive, time-consuming and laborious, and increases input costs. The release rate is uncontrollable, especially nitrogen is very easy to cause runoff, leaching, ammonia volatilization, nitrification-denitrification loss, which greatly reduces the utilization rate of fertilizers, not only wastes resources, but also causes huge pressure on the environment
