Embodiment 1

[0042] Weigh 7.5kg of bentonite with calcium+magnesium content of about 500mg / kg, Ca(OH) 2 2.5kg, each of which was crushed to about 90-110 meshes, and then the two were mixed, drum granulated, and sieved to obtain granules with a particle size of 2.00-2.50mm.

Embodiment 2

[0044] Weigh 6.6 kg of bentonite, 22.2 kg of Ca(OH), 0.6 kg of humic acid, 0.3 kg of polyacrylamide, and 0.3 kg of polyvinyl alcohol with a calcium+magnesium content of about 300 mg / kg. Each of them is crushed to about 90-110 meshes, and then the components are mixed, drum granulated, and sieved to obtain granules with a particle size of 2.00-3.00 mm.

Embodiment 3

[0046] Weigh 7.2kg of bentonite with calcium+magnesium content of about 800mg / kg, Ca(OH) 2 1.8kg, humic acid 0.5kg, polyacrylamide 0.2kg, polyvinyl alcohol 0.3kg. Each of them is pulverized to about 90-110 meshes, and then the components are mixed, drum granulated, and sieved to obtain granules with a particle size of 2.50-3.50 mm.

Abstract

The invention relates to a water-retention soil-loosening soil conditioning agent and a preparation method. The soil conditioning agent comprises bentonite of which the content of calcium+magnesium is 200-1000mg / kg and Ca(OH)2, and can also comprises humic acid, polyacrylamide, polyvinyl alcohol and the like. The invention further relates to a preparation method and an application of the water-retention soil-loosening soil conditioning agent.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a water-retaining soil loosening agent and a preparation method and application thereof. Background technique [0002] Due to years of continuous cropping, irrational application of a large amount of inorganic chemical fertilizers, and the influence of climatic conditions, the phenomenon of soil acidification in my country has become increasingly serious. The area of ​​acidified soil has increased year by year, and the degree of soil acidification has accelerated significantly. Soil acidification not only leads to serious loss of soil nutrients and poor soil, but also reduces the ability of crops to resist diseases and insect pests, eventually leading to a decrease in crop yield. [0003] Soil conditioner refers to the materials added to the soil to improve the physical, chemical and / or biological properties of the soil, such as improving soil structure, reducing soil salinity hazards,...
