Remediation agent for improving soil for vegetable continuous cropping

Abstract

The invention discloses a remediation agent for improving soil for vegetable continuous cropping. The remediation agent is made from the following raw materials, by weight part, 3-4 of diaminoferric xanthohumate, 1.5-1.6 of sodium polysulfide, 18-19 of tea powder, 6-7 of sheep bone meal, 12-14 of powdery pomegranate rinds, 5-6 of maple syrup, 2.8-3.2 of a paecilomyces lilacinus preparation, 5-6 of calcium superphosphate, 66-74 of polluted pig dung and urine, 18-20 of a black liquor from papermaking, 3.8-4.2 of a nitric acid solution with the concentration being 10%, 15-16 of a thick alum liquid and a proper amount of water. In the remediation agent, organic materials, such as tea powder and sheep bone meal, together with the biological preparation are adopted for action on the soil. The remediation agent can supplement nutrients and resist soil-borne pathogens and soil pests, thereby effectively preventing nutrient imbalance of the soil and breeding of a number of pathogens due to vegetable continuous cropping. The remediation agent has an obvious promotion effect on improving the use efficiency of a land and the yield and quality of vegetables.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a restoration agent for improving soil for continuous cropping of vegetables. 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 a...

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] After continuous cropping of vegetables, soil pathogens and root-knot nematodes occur seriously, and at the same time, there is a lack of nutritional composition, and the soil environment deteriorates, which will seriously affect the yield and quality of subsequent vegetables. If the soil is not improved and repaired, economic benefits will be significantly reduced

[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
