Embodiment 1

[0024] A soil conditioner provided in this example, comprising 90% of purified attapulgite, 6% of fulvic acid, 2% of nano-scale carbonized astragalus slag powder, 1% of nano-scale modified cellulose powder, and monosodium glutamate by weight The tail liquid is 1%, and the soil conditioner is a solid powder with a pH value of 9.0.

[0025] The monosodium glutamate tail liquid is a commercially available product, purchased from Dongguan Yixiang Fertilizer Company, which can improve soil physical and chemical properties, water retention and fertility and air permeability, and play the role of maintenance, maturation, maturation, and soil improvement, and can improve the quality of crops at the same time. Stress resistance, thereby improving crop yield and quality.

[0026] The preparation method of soil conditioner in the present embodiment, concrete steps are:

[0027] (1) Ball mill the attapulgite raw ore in a ball mill, pass through a 100-mesh sieve, heat and stir the attapul...

Embodiment 2

[0031] A soil conditioner provided in this example, comprising 88% of purified attapulgite, 8% of fulvic acid, 2% of nanoscale carbonized astragalus slag powder, 1% of nanoscale modified cellulose powder, and monosodium glutamate by weight The tail liquid is 1%, and the soil conditioner is a solid powder with a pH value of 8.0.

[0032] The preparation method of soil conditioner in the present embodiment, concrete steps are:

[0033] (1) Ball mill the attapulgite raw ore in a ball mill, pass through a 100-mesh sieve, heat and stir the attapulgite raw ore powder in a water bath at 60°C, and ultrasonically treat it for 4 hours, then add attapulgite raw ore quality 3% sodium hexametaphosphate, Centrifuge at a speed of 2000r / min to remove impurities, take the supernatant, and obtain the purified attapulgite slurry;

[0034] (2) The plant straw is surface-activated by potassium hydroxide solution, dried, pulverized and processed to nano-scale to obtain nano-scale modified cellulos...

Embodiment 3

[0037] A soil conditioner provided in this example, comprising 95% of purified attapulgite by weight, 3% of fulvic acid, 1% of nano-scale carbonized astragalus slag powder, 0.5% of nano-scale modified cellulose powder, and monosodium glutamate The tail liquid is 0.5%, and the soil conditioner is a solid powder with a pH value of 8.5.

[0038] The preparation method of soil conditioner in the present embodiment, concrete steps are:

[0039] (1) Ball mill the attapulgite raw ore in a ball mill, pass through a 100-mesh sieve, heat and stir the attapulgite raw ore powder in a water bath at 60°C, and ultrasonically treat it for 4 hours, then add attapulgite raw ore quality 3% sodium hexametaphosphate, Centrifuge at a speed of 2000r / min to remove impurities, take the supernatant, and obtain the purified attapulgite slurry;

[0040] (2) The plant straw is surface-activated by potassium hydroxide solution, dried, pulverized and processed to nano-scale to obtain nano-scale modified ce...

Abstract

The invention provides a soil conditioner and a preparation method and application thereof, and relates to the field of soil improvement. The soil conditioner comprises the following components in percentage by weight: 88%-95% of purified attapulgite, 3%-8% of fulvic acid, 1%-2% of nanoscale carbonized astragalus residue powder, 0.5%-1% of nanoscale modified cellulose powder and 0.5%-1% of monosodium glutamate tail liquid. The soil conditioner can effectively increase the content of organic matters, available phosphorus and available potassium in soil, increase the pH value of the soil and reduce the content of heavy metals chromium and cadmium in the soil, so that the soil structure is effectively improved, the crop growth is promoted, and the quality of agricultural products is improved.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a soil conditioner and its preparation method and application. Background technique [0002] As the contradiction between population and environmental resources becomes increasingly prominent, soil degradation has become a major global problem. my country's soil resources are not optimistic. On the one hand, my country's per capita soil resources are relatively small. On the other hand, with the development of urbanization, a large amount of arable land has been swallowed up. Therefore, it is necessary to increase the intensity of soil use to obtain more soil. Productivity. At the same time, the quality of my country's soil varies from good to bad, and the overall quality is low and accompanied by intensified degradation phenomena. The phenomena of soil erosion, soil acidification, and salinization are accelerating and expanding. Soil acidification is accelerating and expanding i...
