Ecological granular fertilizer for corn planting and preparation method of ecological granular fertilizer

Abstract

The invention discloses an ecological granular fertilizer for core planting and a preparation method of the ecological granular fertilizer. The ecological granular fertilizer is characterized by comprising the following raw material components in parts by weight: 40-50 parts of urea, 30-40 parts of rice straw ash, 18-22 parts of plant vines, 12-14 parts of chicken manure, 0.3-0.5 part of molasses, 0.2-0.4 part of mixed bacterial powder, 0.2-0.4 part of abamectin, 2-4 parts of microelements and 3-5 parts of powdered rock phosphate. According to the ecological granular fertilizer provided by the invention, urea is adopted as a binder, and abamectin is also added, so that the insecticidal and insect prevention efficacy is obvious, harm to the crop root system by injurious insects is reduced, moreover, the powdered rock phosphate has a higher material water absorption stability, and accordingly, an excellent soil environment is provided for crop growth; besides, the prepared fermented fertilizer is rich in nutrient content, therefore the crop fertilizer absorption level is greatly improved, the crop resistance is enhanced, the yield and the quality are improved, high safety and environmental protection are achieved, the soil structure is not destroyed, and harm to corn planting despite excess fertilization is avoided.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an ecological granular fertilizer for corn planting and a preparation method thereof. Background technique [0002] Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. But it also has some disadvantages, such as its nutrient ratio is always fixed, but the types, quantities and ratios of nutrient elements required by different soils and different crops are varied. [0003] In recent years, only nitrogen, phosphorus, and potassium are applied to plots without the application of medium and trace elements, and the absorption effect of crops on nitrogen, phosphorus, and potassium nutrients has become worse and worse. In some areas, the limiting factor for crop...

Problems solved by technology

However, there are many varieties of biological fertilizers, microbial fertilizers, biological phosphate fertilizers, and biological potassium fertilizers in China. As the main fertilizer, with a single effect and high price, my country's microbial fertilizer industry still has problems of low overall level, insufficient technological innovation, and unstable product quality and application effect.
