Enzymatic soil conditioner

Abstract

The invention discloses an enzymatic soil conditioner, which is made from the following raw materials, by weight part, 15-18 of beer's grains, 2-3 of carboxymethyl cellulose, 5-6 of calcium superphosphate, 6-8 of charcoal, 5-6 of yak bone meal, 7-8 of urea, 2.3-2.5 of a cellulase preparation, 1.4-1.5 of a sucrase preparation, 1.5-1.7 of a protease preparation, 1.8-2.0 of a hemicellulase preparation, 66-68 of polluted pig dung and urine, 14-16 of a black liquor from papermaking, 3.9-4.1 of a nitric acid solution with the concentration being 10%, 12-13 of a thick alum liquid and a proper amount of water. In the soil conditioner, based on the addition of multiple organic and inorganic compound raw materials, multiple enzymic preparations, such as cellulase, sucrase, protease, and hemicellulase, are utilized, and a modified thick alum liquid with a large specific surface area is used for fixing the enzymic preparations. The soil conditioner can participate in many biological activities in the soil, increase the content of active organic matters, and participate in conversion of nutrients. Effective fertilization of the soil is achieved, and yield increase of poor soil is achieved.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an enzymatic 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...

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

[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
