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, the cycle of soil improvement is long and the cost is high, so it cannot be applied on a large scale
[0003] In winter, the soil is froz

Embodiment Construction

[0019] A soil conditioner suitable for soil freezing in winter, made of the following raw materials in parts by weight (kg): fruit puree 14, calcium lignosulfonate 2, sodium octapolyborate tetrahydrate 3, wood vinegar 4, horse manure 25. Rapeseed cake 13. Carbonized wheat husk 8. Plant ash 10. Polluted pig manure 40. Papermaking black liquor 10. 10% nitric acid solution 2.6. Alum slurry 9. Appropriate amount of water.

[0020] The specific steps of the described soil conditioner preparation method applicable to winter soil freezing are as follows:

[0021] (1) Mix the fruit puree, horse manure, and rapeseed cake, add 1.5 times the total weight of water, mix well, retting and ferment for 3 weeks, crush and separate the fermented material to obtain fermented residue and fermented liquid for later use;

[0022] (2) Dried papermaking black liquor and put it into a calciner, calcined at 430°C for 60 minutes, took it out, mixed it with polluted pig manure and urine, added 3 times th...

Abstract

The invention discloses a soil conditioner for soil freezing in winter. The soil conditioner is made from the following raw materials, by weight part, 14-16 of fruit paste, 2-3 of calcium lignosulphonate, 3-5 of disodium octaborate tetrahydrate, 4-5 of a pyroligneous acid liquor, 25-26 of horse dung, 13-15 of rape seed cake, 8-10 of carbonized wheat husks, 10-12 of plant ash, 40-45 of polluted pig dung and urine, 10-11 of a black liquor from papermaking, 2.6-2.7 of a nitric acid solution with the concentration being 10%, 9-10 of a thick alum liquid and a proper amount of water. Through addition of hot raw materials including horse dung and rape seed cake, the soil conditioner can provide large heat during degradation in soil, and through addition of plant ash and fermented thoroughly-decomposed materials, the color of soil can be deepened, thereby improving the heat absorption capacity of the soil and increasing the temperature of the soil. Phenomenon that soil frozen in winter results in increased use cost of the soil and a bad effect on the yield of crops is prevented, and the soil in spring is unfrozen ahead of time, thereby increasing the economic benefit.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil conditioner suitable for soil freezing in winter. 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 ...
