Problems solved by technology

However, its original ecology is in the form of minerals and cannot be applied directly. If it is crushed and applied, it will be scattered with the wind during application, causing environmental pollution, fertilizer loss and waste, and increased labor intensity.
If you simply add water before application or mix it with wet materials to form granules, the granules are easy to agglomerate after drying, the ingredients are not easy to release, and the granules are easy to break when dry, especially during transportation. storage
In addition, there are no other reports about guano phosphate fertilizer

Abstract

The granular guano fertilizer is prepared with guano as natural calcium phosphate, which can not be applied directly and will waft with wind if being crushed simply. The present invention produces granular guano fertilizer with guano and adopting calcined gypsum and carboxymenthyl cellulose as additive. The granular guano fertilizer may be well applied, and is easy dissolved in water to release its effect components for crop to absorb fast.

Description

technical field [0001] The present invention relates to a granular guano phosphate fertilizer (seadird guano phosphate) and a preparation method thereof Background technique [0002] Guano phosphorus is also called natural calcium phosphate. It is formed by the accumulation of seabird excrement and bird carcasses hundreds of millions of years ago. The difference from ordinary phosphorus is that it is rich in organic phosphorus, high in calcium and low in fluorine. , and rich in trace elements, it can be applied to crops and flowers. However, its original ecology is in the form of minerals and cannot be applied directly. If it is crushed and applied, it will be scattered with the wind during application, causing environmental pollution, fertilizer loss and waste, and increased labor intensity. If you simply add water before application or mix it with wet materials to form granules, the granules are easy to agglomerate after drying, the ingredients are not easy to release, an...
