Abstract

The invention relates to a BB fertilizer suitable for tobacco planting and a preparation method. A slow-release BB fertilizer belongs to the technical field of fertilizer production, and is composed of 30-60 parts of coated urea, 10-25 parts of potassium sulfate, 60-80 parts of an organic fertilizer and 8-10 parts of a composite microbial agent. According to the BB fertilizer, the effective utilization rate of nitrogen, phosphorus and potassium can be increased by about 20%. By controlling the application of the BB fertilizer, the fertilizer consumption is reduced, the fertilizer utilization rate is increased, the fertilization frequency is reduced, the nutrient loss is reduced, and the labor cost and the fertilizer cost are reduced.

Description

Technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a BB fertilizer suitable for tobacco planting and a configuration method. Background technique [0002] As an important economic crop in my country, tobacco has an important position in promoting farmers' income. At present, tobacco-growing soil is facing problems such as soil degradation caused by long-term application of chemical fertilizers, fertilizer loss and reduced utilization rate caused by a large number of concentrated fertilization, so it is the current tobacco to improve soil through green manure, improve fertilizer utilization efficiency through fertilizer preparation, and reduce fertilizer application. Major and urgent problems faced in production. [0003] The application number is 201810991588.X discloses a special organic compound fertilizer for tobacco. The special organic compound fertilizer for tobacco includes 18-32 parts of organic manure, 12-22 par...
