Multiple effect CO2 fertilizer

Abstract

The multiple effect CO2 fertilizer consists of two components, the component A is ammonium bicarbonate and the component B is potassium bisulfate and / or sodium bisulfate. It is suitable for applied to crop in protecting field and has the advantages of reliable effect, easy application, low cost, safe storage, etc. Its application time, site and CO2 density inside the green house may be controlled as required. The residuum after releasing CO2 is solid quick acting fertilizer capable of meeting the need of crop and without may residual pollutant.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizer products, in particular to a multi-effect carbon dioxide fertilizer. It is suitable for fertilizing crops in protected areas. Background technique [0002] At present, my country's agriculture is transforming from traditional agriculture to high-efficiency agriculture. Protected cultivation (that is, greenhouse cultivation) has become an important cultivation method. The vegetable greenhouse alone has reached more than 10 million mu, and it is still increasing rapidly. This situation creates a huge demand for CO2 fertilizers. As we all know, because the added value of agricultural production is relatively low, the carbon dioxide used as fertilizer must be reliable in effect, easy to use, and low in cost. However, none of the existing carbon dioxide products (including the method for preparing it) fully meets this requirement. The current situation and existing pr...

Problems solved by technology

It has the following disadvantages: users need to purchase special equipment, the operation is complicated, and it is difficult to widely promote

These products have two common disadvantages: (1) The law of crops absorbing carbon dioxide is that there are more sunny days and less cloudy days, and they are released at night. However, after these products are applied to the soil, their carbon dioxide is continuously released

The result will be insufficient during the day (especially in sunny days) and wasted at night

(2) The total amount of carbon dioxide available is limited, coupled with the two factors of dispersion and waste, it is impossible to fully meet the needs of crops, and it is impossible to produce stable and reproducible effects

This method has two disadvantages: (1) sulfuric acid is a strong corrosive liquid, its transportation, packaging and use are very troublesome, and it is prone to pollution and injury accidents

(2) When applying, a set of special equipment or 15-25 acid-resistant tanks are required for each mu of land, and special personnel are required to manage it, which is labor-intensive and time-consuming

However, it has not yet been resolved
