Problems solved by technology

Although my country has a large resource reserve of attapulgite, due to its late discovery, its development and utilization level is low, and the foundation of the national non-metallic mineral processing industry is relatively weak, and the attapulgite products that can be produced are still relatively low compared with other countries. Quite few, so that the application of this economically significant mineral deposit is limited to general fillers, and even exported cheaply in the form of raw soil, resulting in a waste of resources

Abstract

The invention belongs to the technical field of a fertilizer, and more specifically relates to an attapulgite-based fertilizer synergist having soil improvement effect. The attapulgite can use own surface activity, adsorptivity, catalysis performance, filtering effect, ion exchange effect, complexation effect and electrostatic interaction, a soil pH value can be adjusted by two items, and attapulgite can provides appropriate growth environment for crops. The attapulgite can change physical and chemical properties of the soil, reduces soil unit weight, promotes formation of a soil gel state, enhances soil permeability, absorbs harmful heavy metals in soil, and inhibits insect disease; beneficial elements in the soil can be converted through chelating effect, nutrition balance is reached, crop growth is cooperated, output is increased, and agricultural product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an attapulgite-based fertilizer synergist with soil improvement function. Background technique [0002] With the rapid development of my country's modern intensive agriculture, long-term and unreasonable large-scale use of inorganic fertilizers has gradually destroyed the farmland soil structure, changed the physical and chemical properties of the soil, and caused soil compaction and degradation. As a result, the yield and quality of crops will decline, and exogenous pollutants will enter animals and humans through water, air and food chain cycles, thereby endangering the health of humans and animals, causing cancer or chronic diseases, etc. [0003] Attapulgite minerals are distributed almost all over the world. Many attapulgite ores have been found in Gansu, Jiangsu, Anhui and other places in my country, and Jiangsu Dingtai ranks first in output. It has been pro...
