Problems solved by technology

[0002] At present, farmyard manure (organic fertilizer) and chemical fertilizer (inorganic fertilizer) are generally used in agricultural production, especially because the application of chemical fertilizer is not good for soil protection, which often makes the soil harden, and the price of chemical fertilizer is high and the quantity is insufficient, so the supply exceeds demand

Embodiment Construction

[0007] Bentonite is a clay rock with montmorillonite as the main mineral. In addition to montmorillonite, it often contains clay minerals such as illite and kaolinite, as well as non-clay minerals such as zeolite and cristobalite. Montmorillonite is a layered hydrous aluminosilicate mineral, composed of two silicon-oxygen tetrahedrons sandwiching an aluminum (magnesium) oxygen (oxygen hydroxide) octahedron, and belongs to the 2:1 layer type. Part of the high-priced ions in the crystal are replaced by low-priced ions, resulting in permanent negative charges between the crystal layers. It relies on the adsorption of cations between the crystal layers to achieve charge balance, and the adsorbed cations between the crystal layers are exchangeable. The above structural characteristics of montmorillonite determine the following physical and chemical properties of bentonite:

[0008] (1) It has strong water absorption and expansibility, can absorb 8-15 times the amount of water of it...

Abstract

The invention relates to an agricultural fertilizer. The fertilizer is prepared from bentonite and nitrogen ammonium carbonate through mixing, wherein the content of montmorillonite in the bentonite is 70%-80%, the expansion multiple of the bentonite is larger than or equal to 12 ml / g, and the water content is lower than or equal to 12%; during mixing, the weight ratio of ammonium carbonate to the bentonite is 2.6-6.9. The agricultural fertilizer has a nitrogen fixation function by the aid of the water absorption, the adsorbability and the cation exchange capability of the bentonite, the fertilizer effect loss of ammonium carbonate is reduced, the fertility is prolonged, the agricultural fertilizer can prevent the soil hardening risk of ammonium carbonate if used for a long time and can have a conditioning and moisture keeping function on soil, and trace elements are introduced. The mixed ammonium carbonate fertilizer is lower in production cost, and input of agriculture production can be reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural chemical fertilizer. Background technique [0002] At present, farmyard manure (organic fertilizer) and chemical fertilizer (inorganic fertilizer) are generally used in agricultural production, especially because the application of chemical fertilizer is unfavorable to the protection of the soil, which often makes the soil harden, and the price of chemical fertilizer is high and the quantity is insufficient, so the supply exceeds demand . Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an agricultural chemical fertilizer. [0004] The technical scheme that realizes the object of the present invention is: a kind of agricultural chemical fertilizer, wherein chemical fertilizer is mixed by bentonite and ammonium nitrogen carbonate, and wherein the montmorillonite content of bentonite is 70%-80...
