Abstract

The invention relates to an improver for saline-alkali soil. The improver comprises a powder agent and a water agent, wherein the powder agent comprises the following components: organic matters, plant mycelium protein powder, active calcium, calcium superphosphate, aluminum sulfate, fatty alcohol polyoxyethylene ether ammonium sulfate, amino acid powder, bacillus subtilis and photosynthetic bacteria, and the water agent comprises the following components: citric acid, fulvic acid, humic acid, malic acid, maleic acid, fumaric acid, L-tartaric acid, pyrophosphoric acid, humic acid, lactic acid, oxalic acid, salicylic acid, sodium ion adsorbent, Tween-80 and water. The improver disclosed by the invention can improve the soil from multiple angles, namely soil structure, microorganism species, a chemical method and the like, obviously promote the release of iron and phosphorus in the soil, improve the soil structure, effectively reduce the content of sodium ions in the soil, reduce the pH value of the soil and restore land to a normal planting state after being used continuously for two years.

Description

technical field

[0001] The invention relates to a soil conditioner, in particular to a conditioner for saline-alkali soil. Background technique

[0002] Saline-alkali land means that the soil (especially the soil surface 0-20cm) contains a large amount of soluble salts such as sodium chloride and sodium carbonate, which seriously affects the growth of the plant. Saline-alkali land is generally formed under the influence of natural conditions and human activities, such as arid climate and little rainfall, large evaporation, low and flat terrain, high groundwater level, and high salinity. The pH value of a large area of ​​saline-alkali land in northeastern my country is above 8.0. The existing saline-alkali land improvement technologies include: 1. Physical improvement: such as leveling the land, loosening the soil in time, and terrain that is too high; 2. Improvement of water conservancy projects: such as irrigation and drainage 3. Chemical improvement: There are solid and li...

Examples

Embodiment 1

[0021] Preparation of powder

[0022] Weigh the following raw material components:

[0023] 15g peat, plant mycelial protein powder (purchased from Harbin Pharmaceutical Sixth Factory) 8g, active calcium 10g, superphosphate 10g, aluminum sulfate 35g, fatty alcohol polyoxyethylene ether ammonium sulfate 1.5g, amino acid powder (purchased from Jinshan, Shandong Province) Bioengineering Co., Ltd.) 5g, Bacillus subtilis 0.15g, photosynthetic bacteria 0.15g;

[0024] The fatty alcohol polyoxyethylene ether ammonium sulfate is first adsorbed with zeolite powder, that is, the fatty alcohol polyoxyethylene ether ammonium sulfate is added to 800-1000 g of zeolite powder, mixed and stirred evenly, and then the above raw materials and adsorbed fatty alcohol polyoxyethylene ether sulfuric acid are added. The ammonium zeolite powder is mixed evenly, added to the pulverizer and pulverized to 80 mesh, that is, it is obtained.
