Embodiment 1

[0042] All four sources of calcium were treated with concentrated monosilicic acid containing 15% silicon, and the ratio of calcium-rich material: silicon material for each treatment was 10:1. The treatment process includes the following steps:

[0043] The first step: crush the above four calcium-rich materials with a standard pulverizer until the particle size is less than 2 mm;

[0044] The second step: mixing the crushed calcium-rich material and the mineral material with a monosilicic acid content of 15% in a weight ratio of 10:1;

[0045] Step 3: Add 50% by weight of pure water to the mixture under the conditions of normal pressure, humidity 50%, and temperature 0-100°C, cultivate for one week, and stir for 15 minutes every day;

[0046] Step 4: Put the cultured mixture in an oven at 65°C to dry until the moisture content is 5-8%;

[0047] Step 5: Grind and pass through a 1mm sieve.

[0048] The silica content was determined by water and acid extraction by the followi...

Embodiment 2

[0063] Culture tests with treated and untreated calcium-rich materials and soils were carried out at the Institute of Basic Biological Problems of the Russian Academy of Sciences. Lime and gypsum were used as calcium-rich substances in this experiment. The treatment process includes the following steps:

[0064] Step 1: Pulverize the calcium-rich material to a particle size smaller than 2 mm;

[0065] The second step: mix calcium-rich and silicon-rich substances in a weight ratio of 10:1, the silicon-rich substance is concentrated monosilicic acid with 15% silicon or amorphous silicon dioxide chemically pure gas phase II produced by Russia Akkord Co., Ltd. Silicon oxide (SiO 2 -3), 0.007-0.030μm particle size, white, CAS 112945-52-5, pH 6.9 treatment;

[0066] The third step: under normal pressure, humidity 5-95%, temperature 20-24°C, add 50% by weight pure water to the mixture uniformly mixed in the second step, and cultivate for 1 day;

[0067] Step 4: Dry in an oven at ...

Embodiment 3

[0091] The second greenhouse experiment was carried out at the Institute of Basic Biological Problems of the Russian Academy of Sciences. The main purpose of this experiment was to determine the effect of treated and untreated calcium-rich substances on the biomass and phosphorus and iron uptake of barley acid-alkaline soil. Two calcium-rich substances, lime and gypsum, were used in the experiment. The chemical compositions of these substances are listed in Table 1.

[0092] The cultivation experiments with treated and untreated calcium-rich materials and soils were organized and carried out at the Institute of Basic Biological Problems of the Russian Academy of Sciences. Lime and gypsum were used as calcium-rich substances in this experiment. The treatment process includes the following steps:

[0093] Step 1: The calcium-rich material is pulverized with a standard pulverizer until the particle size is less than 2 mm;

[0094] The second step: mix the calcium-rich material...

Abstract

The invention discloses a silicon-rich soil conditioner, its preparation method and application, and relates to agriculture and improving the efficiency of natural and synthetic calcium-rich substances by using silicon-rich materials in liquid or solid form. The method includes preparation before mixing, addition of water, incubation and drying. The method can be used to prepare high-efficiency agricultural soil improver.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to a silicon-rich soil improver and its preparation method and application. Background technique [0002] Calcium is one of the most commonly used elements in agriculture. Natural and synthetic calcium-rich materials are used to improve soil chemical properties, increase the pH of acidic soils, reduce the mobility of heavy metals; optimize soil physical properties, etc. [0003] Calcium has important functions in plants to increase nutrient uptake, build strong cell walls for plants and increase vigor. [0004] However, application of calcium-enriched products can fix soluble P and convert plant-available P to plant-ineffective P. This process occurs according to the following reactions: [0005] The presence of calcium in the soil leads to the fixation of phosphorus: [0006] ½ Ca 2+ + H 2 РO 4 - ↔ Ca(H 2 PO 4 ) 2 [0007] Ca 2+ + HРO 4 2- ↔ CaHPO 4 [000...
