Problems solved by technology

[0004] 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
In addition, due to the long-term excessive input of nitrogen, phosphorus and potassium in the farmland by far

Abstract

The invention discloses a special long-lasting formula fertilizer for corns and a preparation method thereof. The special long-lasting formula fertilizer for corns comprises the following components in parts by weight: 35-42 parts of polypeptide urea, 5-10 parts of urea ammonium nitrogen fertilizer, 20-30 parts of urea phosphate, 20-30 parts of potash magnesium sulphate fertilizer, 0.2-0.5 parts of zinc sulfate, 0.2-0.4 parts of manganese sulfate, 0.05-0.5 parts of ferrous sulfate, 0.2-0.6 parts of sodium borate, 0.5-1 part of chloromethylpyridine, 0.005-0.01 parts of compound sodium nitrophenolate, and 0.5-1 part of auxiliary material. By adopting the special long-lasting formula fertilizer for corns provided by the invention, nutrients are supplied to the corns in a comprehensive and balanced manner; release of nutrient elements is controllable, coordinated and lasting; top application is not needed after one-off fertilization; the quality and yield of the corns are significantly improved; the special long-lasting formula fertilizer has significant economic benefits, and is suitable for most of soil in a corn planting region in China.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a long-acting formula fertilizer for corn and a preparation method thereof. Background technique [0002] Corn is one of the three major food crops in the world. In my country, the output of corn has already ranked first among the three major food crops, which is of great strategic significance to ensure my country's food security. Corn is not only an important food crop, but also an important feedstock. agricultural, medicinal and energy crops. [0003] Corn plants are tall, with thick leaves and well-developed root systems. They have a large demand for nitrogen, phosphorus and potassium throughout their lives, especially for nitrogen. Nitrogen is not only an important living substance such as corn protein and chlorophyll, but also a decisive factor that affects corn photosynthesis. , Maize is sensitive to nitrogen fertilizer, and nitrogen application can signif...
