Problems solved by technology

[0008] The above scheme uses polyacrylamide or polyacrylic acid as water-retaining agent, both of which are refractory organic polymers. Long-term application of the residue in the soil will cause adverse effects on the environment, and the added aluminum salt will be absorbed by the crops, and the aluminum ions will affect the growth of the crops. Both food safety and food safety have certain risks, so they need to be improved

Abstract

The invention belongs to the field of soil amendments, and particularly relates to an alkaline soil amendment. The alkaline soil amendment is prepared from polyglutamic acid, activated humic acid, amino acid waste liquid, ammonium polyphosphate, citric acid fermentation waste residues, Pullulan polysaccharide, polyaspartic acid, sodium carboxymethyl starch, tetrahydropyrimidine and trehalose. Accordingly, the purpose of improving alkaline soil is achieved by adding a water retaining agent to control salt, adding acidic organic matter to activate humic acid, adding the amino acid waste liquid to control the pH value, adding a chelating agent to prevent solidification and adding an osmotic pressure stabilizer to prevent root dehydration. The amendment has the advantages that raw materials are natural, non-toxic and biodegradable, the cost is low, the yield is high, and the effectiveness of soil nutrients can be fully achieved; the activated humic acid improving the reactivity of organicmatter and the amino acid waste liquid mainly consisting aginomoto waste liquid are synergized; the water retaining agent, the chelating agent and the osmotic pressure stabilizer act together, and theadvantages of the amendment are strengthened.

Description

technical field [0001] The invention belongs to the field of soil improvers, and in particular relates to an alkaline soil improver, and also relates to the application of the above-mentioned alkaline soil improver. Background technique [0002] With the rapid development of industrial civilization, various consequences at the expense of the environment have been highlighted in recent years, and the natural environment, including soil conditions, has become worse and worse. The specific manifestations are: the decline of soil water retention capacity, the decrease of air permeability, the decrease of decomposition and reduction ability, pesticide residues, water pollution, and soil heavy metal pollution are becoming more and more serious. In addition, the unreasonable production methods of humans have caused secondary salinization of soil in arid and semi-arid areas. [0003] Alkaline soil refers to soil with a pH value greater than 7. The formation of alkaline soil is mai...
