Method for performing natural soil greening on low-lying saline soil by using soil conditioner containing chitosan

Abstract

The invention relates to a method for performing natural soil greening on low-lying saline soil by using a soil conditioner containing chitosan. According to the formula of the soil conditioner, the soil conditioner comprises, by weight parts, 32-34 parts of fermented deer manure, 8-10 parts of sorghum straw powder, 5-7 parts of bentonite, 6-8 parts of biogas residue, 3-5 parts of phosphorite powder, 2-4 parts of chitosan, 2-4 parts of fish bone meal, 1-3 parts of peanut cake, 1-3 parts of egg-shell meal, 2-4 parts of soybean meal, 1-3 parts of ammonium bicarbonate, 1-3 parts of ammonium phosphate, 1-3 parts of ammonium chloride ferric sulfate, 1-3 parts of magnesium hydrogen phosphate, 0.5-0.7 part of phenylacetic acid, 1-3 parts of amino acid salt, 0.2-0.4 part of sodium nitrophenolate, 0.2-0.4 part of brassin, 0.2-0.4 part of gibberellin, 0.1-0.3 part of methanohalophilus zhilinae, 0.1-0.3 part of bacillus coagulans, 0.1-0.3 part of saccharomyces cerevisiae, 0.1-0.3 part of azotobacter vinelandii and 0.1-0.3 part of aspergillus oryzae.

Description

technical field [0001] The invention relates to a soil conditioner containing chitosan, in particular to a method for greening low-lying saline soil with a soil conditioner containing chitosan, and belongs to the technical field of landscaping. Background technique [0002] Soil salinization refers to the phenomenon or process of soluble salt accumulation on the soil surface, also known as salinization. my country's saline soil or saline-alkali soil has a wide distribution range, a large area, and many types, with a total area of ​​about 100 million hectares. It mainly occurs in arid, semi-arid and semi-humid areas. The ground is low-lying, and the groundwater level is relatively high, so it is easy to bring the salt dissolved in the water to the surface. After the water evaporates, the salt remains. Repeating this for a long time, the soil is prone to salinization. [0003] The fundamental purpose of improving saline soil is to reduce the salt in the root layer to a certai...
