Saline-alkali soil improver

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...

Problems solved by technology

Some use a large amount, which is not convenient for construction and use, and some have high cost. The liquid materials include various acids and acid salts. Among them, the use cost and effect are the key factors affecting the promotion

[0003] The patent publication number is CN102199061A, and the patent application date of publication is 2011.9.28, which discloses a microbial saline-alkali soil improvement agent, which uses Bacillus subtilis, photosynthetic bacteria, production-increasing bacteria, lactic acid bacteria, etc. as core raw materials and combines lignite powder, chimney ash and other solid composition, has the characteristics of safety and environmental protection, and can also be used as a fertilizer for plants, but the cost of the improver is high, and it is difficult to popularize and apply

[0005] The patent No. ZL01136114.x discloses a high-efficiency soil improver, which uses water-soluble polymers and solid acids to activate conventional sulfur, gypsum and organic peat that can improve salinized soil. The improver can effectively promote plant It grows on saline-alkali land, but the improver only improves the soil from a single angle, and it is difficult to completely improve the saline-alkali land
