Problems solved by technology

[0006] Although the compound fertilizer industry has been greatly developed, the current compound fertilizers are mainly used for crops, and there is still a big gap between the requirements for lawns and crops.
[0007] There are a small amount of imported lawn fertilizers on the market, but their localization ability is poor, the nutrients are single, and the fertilizer efficiency is not good. They are mainly inorganic chemical fertilizers, and the price is very expensive (about 5,000 yuan per ton). Replacing agricultural chemical fertilizers has exacerbated the compaction of the soil, causing serious breeding of pests and physiological diseases

Abstract

The fertilizer specially for lawn includes inorganic fertilizer 35-75 wt%, organic fertilizer 25-35 wt%, and stuffing and adhesive for the rest. Its production includes one improved pelletizing process, in which, one improved granulating disc resulting in high balling degree and fine homogeneous pellets, one improved drier with external heating and completing one second balling at 60-65 deg.c and one improved sieving system coompleting one third balling comprising sieving, polishing, rounding, coating, oil coating and fine treatment are adopted. The present invention provides one new pelletizing technology.

Description

technical field [0001] The invention belongs to the technical field of soil fertilizers, in particular to special fertilizers for lawns. Background technique [0002] The compound fertilizer characterized by organic and inorganic compound fertilizer products began in the middle and late 1980s. The appearance of this new type of fertilizer is the need of the modernization of organic agriculture, and it is the product of the eager demand of the farmers and the efforts of the majority of scientific and technological personnel. Over the past 10 years, the research and application of this compound fertilizer has made considerable progress. In terms of organic raw materials, it is expanded to more than 20 types of solid and liquid wastes, including sugar industry, animal husbandry, metallurgy, mining, chemical industry, food processing, sanitation and other industries. On the basis of the research on the properties of these wastes, the organic-inorganic formulation principle and...
