Method for carrying out original-soil greening on seawater-dipped saline and alkaline land through salt absorption agents with sugar residue paste

Abstract

The invention relates to a method for carrying out original-soil greening on seawater-dipped saline and alkaline land through salt absorption agents with sugar residue paste. The salt absorption agents with the sugar residue paste are prepared from, by weight, 25-27 parts of biogas residues, 3-5 parts of bentonite, 5-7 parts of haycite, 15-17 parts of sorghum straw powder, 18-20 parts of fermented wild goose dung, 10-12 parts of fermented yellow weasel dung, 5-7 parts of the sugar residue paste, 3-5 parts of sodium hydrogen sulfate, 3-5 parts of ferric pyrophosphate, 1-3 parts of palmitic acid, 1-3 parts of amino acid salt, 0.2-0.4 part of atrazine, 0.2-0.4 part of glyphosine, 0.2-0.4 part of adjusting phosphine, 0.5-0.7 part of Chinese hawthorn leaf extract, 0.5-0.7 part of momordica charantia extract, 2-4 parts of tertiary calcium phosphate, 2 parts of starch-grafting acrylamide polymers, 0.1-0.3 part of methanohalophilus mahii, 0.1-0.3 part of bacillus coagulans, 0.1-0.3 part of brown nitrogen-fixing bacteria, 0.1-0.3 part of aspergillus oryzae and 0.1-0.3 part of trichoderma harziamum.

Description

technical field [0001] The invention relates to a salt-absorbing agent containing sugary sludge, in particular to a method for afforesting original soil of saline-alkali land immersed in seawater by using a salt-absorbing agent containing sugary sludge, belonging to the technical field of landscaping. Background technique [0002] Rivers in coastal areas carry a large amount of sediment and deposit it in the offshore. When it is still in the underwater accumulation stage, it is impregnated by highly mineralized seawater to form saline silt. Before the deposits emerge from water to form land and higher plants grow on them, the accumulation of salt is a geological process. After the higher plants grow, the process of soil salinization begins. Under the action of evaporation, the salt content of the soil surface exceeds that of the saline silt, and the salinity of the groundwater also increases due to evaporation and concentration. Salt accumulation process. Coastal saline so...
