Problems solved by technology

However, the special fertilizer for corn is entirely an inorganic chemical fertilizer, and long-term use will cause damage to the soil structure and seriously damage the soil fertility.
Even if it is the former, although it contains amino acid organic nitrogen fertilizer, the amino acid organic nitrogen fertilizer is still chemically synthesized, but it will not form humus in the soil, and will not help to improve soil structure and fertility

Embodiment Construction

[0021] The invention is a special compound fertilizer for corn determined according to the law of nutrient demand for corn growth and quality formation, and in combination with general conditions of soil nutrients. Based on the combination of organic and inorganic nutrients, the combination of long-acting and quick-acting nutrients, the combination of large, medium and micronutrient elements, and the convenience of manufacture, storage, transportation, and application, it uses large-grained urea (including urea) with a particle diameter of 3-4 mm N46%), slow-release coated urea containing medium and trace elements (containing N30%), organic granular fertilizer (containing organic matter 36%-50%), monoammonium phosphate (containing N 10%, P 2 o 5 44%), potassium sulfate (contains K 2 O50%, S 18%) uniformly mixed. The share (percentage by weight) of above-mentioned each composition is:

[0022] Large granular urea 18-20% Slow-release coated urea 34-36%

[0023] Monoammonium ...

Abstract

The invention relates to a fertilizer. A organic-inorganic slow-release compound fertilizer special for maize, contains grained inorganic nitrogen, phosphorus and potasium fertilizers, which is characterized in that: the grained inorganic nitrogen, phosphorus and potasium fertilizers are macroaggregate urea, slow-release coated urea, monoammonium phosphate and kalium sulphuricum; and the fertilizer is mixed with an organic grained fertilizer used animal manure, bean cake And straw as raw materials; where the fertilizer contains 18-20by weight of macroaggregate urea, 34-36by weight of slow-release coated urea, 15-17by weight of monoammonium phosphate, 14-16by weight of kalium sulphuricum and 14-15by weight of organic grained fertilizer. The invention can provides a long time nutrient based on the nutritional needs of each growth phase of the maize by once fertilization, can hold and improve soil structure and fertility, and solves the technical problems of convenient preparation, storage, transport and fertilization.

Description

Technical field: [0001] The invention belongs to fertilizers, in particular to a special fertilizer for long-acting corn which combines organic fertilizers and inorganic fertilizers. Background technique: [0002] China has been based on agriculture for thousands of years. In the past, the planting industry in agriculture mainly used organic fertilizers such as human and livestock manure, manure, compost, and green manure. In addition to providing organic and mineral nutrients to crops, these organic fertilizers also produce humus that can improve soil structure and soil fertility. However, the fertilizer efficiency of organic fertilizers is slow, and storage, transportation, and application are inconvenient. On the contrary, chemical fertilizers have high nutrient content, fast fertilizer efficiency, and convenient application, storage, and transportation. It replaces the traditional farm organic fertilizer. At present, my country's annual chemical fertilizer consumption ...
