Seed manure specially for corn and its production process

Abstract

The present invention relates to a seed manure specially for corn and its production process. The seed manure contains nitrogen fertilizer, phosphate fertilizer, and potash fertilizer. The raw material of the phosphate fertilizer is calcium superphosphate and monoammonium phosphate with the weight parts of 448 and 153.8, the raw material of the potash fertilizer is potassium sulfate and potassium chloride with the weight parts of 60 and 30, the raw material of the nitrogen fertilizer is ammonium nitrate, ammonium sulfate and monoammonium phosphate, wherein the weight parts of the ammonium nitrate and ammonium sulfate are all 76.9, the nitrogen fertilizer also contains 156.4 weight parts of humic acid. The production process includes the steps of smelting ammonium nitrate, ammoniating, revolving and pelletizing, adding calcium superphosphate, potassium sulfate and humic acid. The seed manure specially for corn of the invention can promote the growth of corn seedling root system, and provide corn seedling with sufficient nutrients.

Description

technical field [0001] The invention relates to a corn seed fertilizer and a production process thereof, in particular to a special corn seed fertilizer and a production process thereof. Background technique [0002] Corn is the main crop in Northeast my country. In 2003, the corn sown area accounted for 25.4% of the national corn sown area, reaching 6.114 million hectares, especially in the middle of Jilin Province, which is known as "China's Corn Belt". Since the 1980s, a large amount of corn has been exported to Japan and other countries, earning foreign exchange for the country, and has become one of the bulk commodities exported by the province. [0003] However, in the past, the main types of chemical fertilizers for corn were 15-15-15 general-purpose fertilizer and 16-12-12 special fertilizer for corn. The ratio of nitrogen, phosphorus and potassium of 15-15-15 compound fertilizer was fixed, and it was easy to cause waste or insufficient single nutrient amount when ap...

Problems solved by technology

Although customary fertilization is suitable for the characteristics of corn's fertilizer requirements and the characteristics of the soil in Northeast China, since the depth of one-time fertilization is more than 10 cm, and in order to prolong the nitrogen release time, it is necessary to add nitrogen long-acting agents. , The ability to absorb fertilizer is poor, and the release of fertilizer is slow, resulting in the phenomenon of weak growth of corn seedlings
