Embodiment Construction

[0014] This specific embodiment adopts the following technical scheme: it includes mudstone, 400-1000 purpose light shale opal, humic acid, organic silicon, calcium carbonate, and the above-mentioned mass ratios are respectively: 60%-80%, 15%-35 %, 2%-3%, 3%-5%, 3%-5%; the rest are impurities.

[0015] The mudstone is a polymorph of natural silicon dioxide (SiO2·nH2O) containing various minerals and chemical components. It contains abundant small-volume (volume 2-5mm) freshwater thin-shelled gill fossils, very light in specific gravity, low in hardness and easy to pulverize into powder. The chemical composition is: 87.18% SiO 2 , 5.32%Al 2 o 3 , 0.66% Fe 2 o 3 , 0.64% CaO, 0.65% K 2 O, 0.10% Na 2 O, 0.01% MnO, 0.20% TiO 2 , 0.093%P 2 o 5 , 0.0084% S, 3.70% LOS; the rest are impurities.

[0016] The humic acid refers to lignite with a particle size of 200-800 mesh.

[0017] The mudstone is made of mudstone with high anion composition; its unique anion composition ha...

Abstract

The invention discloses a conditioner for treating and improving saline alkali soil, relating to the technical field of land improvers. The invention is characterized in that the conditioner comprises the following components in percentage by mass: 60-80% of mudstone, 15-35% of 400-1000-mesh light-weight shale opal, 2-3% of humic acid, 3-5% of organosilicon, 3-5% of calcium carbonate and the balance of impurities. The conditioner avoids secondary emission pollution. The application method is simple and convenient, and saves the time and labor. The conditioner is low in cost and can thoroughly improve the soil.

Description

Technical field: [0001] The invention relates to the technical field of land improvers, in particular to a saline-alkali soil improvement conditioner. Background technique: [0002] There are a lot of saline-alkali land in my country, and the nitrate and soda salt in the saline-alkali cultivated soil have very serious damage to the root system of crops. After the root system of crops is poisoned by saline-alkali, the root system will prematurely senile due to poor growth, and it is also the main cause of various crop diseases. cause. Grain production is low and the quality is poor. Due to the high salinity and high alkalinity in the soil, the organic matter of the soil is destroyed and lost, and the trace elements are extremely scarce. It is sticky when wet and hard when dry. , Increase the oxygen content in the water, provide the basic conditions for crop growth, solve the problem of poor air permeability and water permeability, and the root system of crops often suffers f...
