Description

technical field

[0001] The invention relates to the technical field of soil improvement, in particular to a saline-alkali soil conditioner. Background technique

[0002] Saline-alkali soil is a general term for saline soil and alkaline soil and various salinized and alkaline soils. Among them, saline soil refers to the soil that contains a large amount of soluble salts and makes most plants unable to grow, and its salt content is generally more than 0.6%; alkaline soil refers to the soil whose substitution rate (ESP) of sodium ion cation substitution exceeds 20%. strong alkaline soil. The physical and chemical properties of saline soil are poor. The main performance is that the salinity or alkalinity is too high, which leads to water shortage or poisoning of plant roots. Poor resistance, extremely unfavorable to agricultural production.

[0003] To this end, the Chinese patent literature was searched. In the Chinese patent application literature "saline-alkali soil condi...

Examples

Embodiment 1

[0027] The saline-alkali soil conditioner of the present embodiment comprises the following components by weight: 5 parts of biochar, 35-55 parts of calcined phosphogypsum, 15 parts of briquette ash, 4 parts of modified zeolite, 5 parts of expanded perlite, humic acid 3 parts of powder, 2 parts of citric acid residue, 1 part of polyaluminum iron silicate, 2 parts of diatomite, 0.5 part of calcium activator, 0.2 part of compound biological agent, 3 parts of organic compound fertilizer.

[0028] Wherein, the biochar is mixed with rice husk charcoal, straw charcoal and cow dung charcoal according to the mass ratio of 1:0.8:1.2, after being fully ground, passed through a 80-120 mesh sieve, and the re-powder is evenly mixed.

[0029] Among them, straw charcoal and cow dung charcoal are made by anaerobic pyrolysis at 550°C for 30 minutes, while rice husk charcoal is waste gas produced after straw power generation.
