Abstract

The invention provides a humic acid controlled release blended fertilizer dedicated for corn. The fertilizer is composed of the following components in parts by weight: 288 to 322 parts of common urea, 165 to 179 parts of film-coated controlled release urea, 228 to 273 parts of monoammonium phosphate, 167 to 200 parts of potassium chloride, and 52 to 119 parts of nitro humic acid. The provided fertilizer has a high utilization rate, is very practical, and thus has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a humic acid controlled-release blended fertilizer dedicated to corn. Background technique [0002] Corn is the largest autumn grain crop in Henan Province. In 2010, Henan's summer corn accounted for about 70% of the province's total autumn grain production and about 30% of the annual grain. Corn plays an extremely important role in my country's food security. It is not only an important feed crop, but also an important raw material for food, chemical, fuel, and pharmaceutical industries. Therefore, the importance and product quality of corn have attracted much attention. [0003] Fertilizer is the most important part of agricultural production input, which is related to the sustainable development of my country's soil quality, agricultural cultivation, food security and ecological environment. According to the results of corn fertilizer efficiency experiments ...
