Soil conditioner for soil freezing in winter

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 ...

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 frozen due to low temperature, resulting in soil compaction, decreased air permeability, reduced material exchange with plants, and reduced biological activities in the soil, which slows down or even stops the growth of crops. cost increase

[0004] As a renewable biological resource with a wide range of sources and low cost, pig manure has great potential as a raw material for soil improvement and restoration because it is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium. The feed contains a large amount of additives during the process, resulting in excessive heavy metals and indirectly polluting the excrement
