Problems solved by technology

However, the soil remediation and improvement agents currently on the market have many defects: one is that the raw materials used contain artificially synthesized polymer compounds, which are not easy to decompose in the soil and remain for a long time, which has potential safety hazards; Soils, such as acidic and alkaline soils, have no effective targets for heavy metal pollution and lack of nutrients, resulting in low efficiency of improvement and restoration, or even counterproductive effects; third

Embodiment Construction

[0018] An acidic soil improver, made of the following raw materials in parts by weight (kg): Plant ash 9, apatite powder 2.6, Flammulina velutipes slag 10, bean pod shell powder 5, bagasse 30, magnesium sulfate 1.6, potassium nitrate 4, Lime powder 3, polluted pig manure and urine 65, papermaking black liquor 12, 10% nitric acid solution 3.6, alum slurry 11, appropriate amount of water.

[0019] The concrete steps of described acid soil conditioner preparation method are as follows:

[0020] (1) Mix Flammulina velutipes slag, plant ash, bean pod shell powder, and bagasse, add 1.5 times the total weight of water, mix well, retting and ferment for 3 weeks, crush and separate the fermentation material to obtain fermentation residue and fermentation liquid for later use;

[0021] (2) Dried papermaking black liquor and put it into a calciner, calcined at 450°C for 80 minutes, took it out, mixed it with polluted pig manure and urine, added 3 times the total weight of water, stirred ...

Abstract

The invention discloses an acid soil conditioner, which is made from the following raw materials, by weight part, 9-11 of plant ash, 2.6-2.8 of apatite powder, 10-12 of golden needle mushroom residue, 5-6 of pod powder, 30-34 of bagasse, 1.6-1.8 of magnesium sulfate, 4-5 of potassium nitrate, 3-4 of lime powder, 65-70 of polluted pig dung and urine, 12-15 of a black liquor from papermaking, 3.6-3.8 of a nitric acid solution with the concentration being 10%, 11-13 of a thick alum liquid and a proper amount of water. In the soil conditioner, alkaline raw materials, such as plant ash, are adopted and match thoroughly-decomposed materials including processed pig dung and urine and bagasse, and therefore salt in the soil can be well neutralized. Alkaline-earth metal, such as magnesium sulfate, is added and matches golden needle mushroom residue for prompting activity of rhizosphere microorganisms, prompting insoluble mineral elements in the soil to change into soluble nutrients, and preventing manganese and aluminum damage to the soil. The available phosphorus content is the soil is further increased, and the obstacle of phosphorus deficiency is overcome under the function of application of apatite powder, and the problem that acid soil is low in planting yield is solved.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an acidic soil conditioner. Background technique [0002] Soil improvement is aimed at the poor texture and structure of the soil, and corresponding measures are taken to improve soil properties and soil fertility. Soil improvement and restoration agent is an important application of soil improvement. However, the soil remediation and improvement agents currently on the market have many defects: one is that the raw materials used contain artificially synthesized polymer compounds, which are not easy to decompose in the soil and remain for a long time, which has potential safety hazards; Soils, such as acidic and alkaline soils, have no effective targets for heavy metal pollution and nutrient deficiencies, resulting in low efficiency of improvement and restoration, or even counterproductive effects; third, the long cycle and high cost of soil improvement prevents large-sc...
