Potassium-increasing soil repairing agent

Abstract

The invention discloses a potassium-increasing soil repairing agent. The potassium-increasing soil repairing agent comprises the following raw materials in parts by weight: 22-24 parts of coffee grounds, 8-10 parts of Elodea nuttallii, 2-3 parts of sodium phosphate, 2.3-2.5 parts of polyaspartic acid, 6-7 parts of alcohol waste mash, 1.5-1.8 parts of bamboo leaf flavonoid powder, 15-18 parts of waste tobacco leaf ash, 3-4 parts of carnallite fine powder, 59-61 parts of polluted pen manure, 12-14 parts of papermaking black liquor, 3.5-3.6 parts of a nitric acid solution with concentration being 10%, 9-10 parts of alum slurry, and a proper amount of water. The soil repairing agent aims at the general problem of potassium deficiency of the soil in our country, by adding the potassium-rich raw materials such as waste tobacco leaf ash and carnallite fine powder, through combined action of decomposed organic matters such as coffee grounds and Elodea nuttallii, maximum absorbing capacity of the elements is increased, biological enzyme activity of the soil layers can be promoted by assistance of bamboo leaf flavonoid powder and polyaspartic acid, release and accumulation of the effective potassium element in the soil are realized, and favorable condition can be provided for planting the crops.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a potassium-enhancing soil restoration agent. 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...

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] 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
