Special fertilizer for corn

Abstract

The invention provides a special fertilizer for corn, belonging to the field of mixed fertilizer in agricultural production. The special fertilizer is prepared by subjecting nitrogen fertilizer, potash fertilizer, phosphate fertilizer, silicon fertilizer and indirect fertilizer to uniform mixing and granulation, wherein the obtained mixture contains the following effective components: 10 to 15% of nitrogen, 10 to 20% of potassium, 10 to 15% of phosphorus, 10 to 20% of silicon and 10 to 20% of calcium. The special fertilizer is convenient to apply, has a balanced nutrient system, can meet nutritional demands of corn for elements like nitrogen, phosphorus, potassium, silicon and calcium, and is capable of obviously reducing influence of natural disasters, increasing the output of corn, improving the utilization rate of fertilizer, saving cost and enhancing efficacy.

Description

technical field [0001] The invention relates to the field of mixed fertilizers in the field of agricultural production, in particular to a special fertilizer for corn. Background technique [0002] At present, the common fertilizers in corn planting are mainly nitrogen, phosphorus, and potassium fertilizers. The fertilizers increase the amount of fertilizers containing nitrogen, phosphorus, and potassium elements, and ignore the use of silicon fertilizers and indirect fertilizers, resulting in nutrient imbalance. The problems of partial application of chemical fertilizers and unbalanced nutrition supply and demand in agricultural production have always existed. The nutrients required for corn growth cannot be met, and it is impossible to coordinate the balance of soil nutrients to achieve high yields of corn. On the other hand, it is very important to enhance the lodging resistance of corn. The important silicon element and calcium element, which is very important for increa...

[0002] At present, the common fertilizers in corn planting are mainly nitrogen, phosphorus, and potassium fertilizers. The fertilizers increase the amount of fertilizers containing nitrogen, phosphorus, and potassium elements, and ignore the use of silicon fertilizers and indirect fertilizers, resulting in nutrient imbalance. The problems of partial application of chemical fertilizers and unbalanced nutrition supply and demand in agricultural production have always existed. The nutrients required for corn growth cannot be met, and it is impossible to coordinate the balance of soil nutrients to achieve high yields of corn. On the other hand, it is very important to enhance the lodging resistance of corn. The important silicon element and calcium element, which is very important for the increase of corn production, are not paid enough attention, and the quality assurance, efficiency increase, cost saving and production increase cannot be realized.
