Saline-alkali land improvement fertilizer and preparation method thereof

Abstract

The invention discloses a saline-alkali land improvement fertilizer and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing 5-20 parts of phosphogypsum, 3-5 parts of a sodium ion adsorbent and 5-10 parts of medical stone in a mixing machine so as to obtain a material A; uniformly mixing 5-10 parts of an acidic conditioning agent, 15-40 parts of soluble humic acid and 20-35 parts of wood vinegar liquid, adding the obtained liquid B into the material A in the mixing machine, performing uniform mixing and stirring so as to obtain slurry C, feeding 35-50 parts of farmyard manure and 15-20 parts of straw powder into the slurry C, performing uniform mixing, feeding 2-5 parts of a microbial agent and 10-15 parts of 61-65% Tween-80 into the material liquid, and performing uniform mixing, thereby obtaining the saline-alkali land improvement fertilizer. As multiple saline-alkali land improvement measures that the soil salinity and alkalinity are improved by using a chemical method, the physical and chemical properties and the structure of soil are improved by using microorganisms, nutrient components of soil are improved by adding fertilizers, and the like, are integrated, the saline-alkali land improvement fertilizer is good in saline-alkali land improvement effects, and long in action time, and virtuous circle of saline-alkali land soil is achieved.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a saline-alkali land improvement fertilizer and a preparation method thereof. Background technique [0002] In saline-alkali land, due to the high salinity and high alkalinity in the soil, the soil organic matter is destroyed and leached, and the trace elements are scarce. The most intuitive manifestation is soil compaction and poor soil structure. After irrigation, the soil particles are easy to disperse automatically and form crusts. This prevents water infiltration and reduces the water storage capacity of the soil. At this time, even if a large amount of fertilizer is invested, it cannot be absorbed and utilized by crops, resulting in the negative effect of high input and low output. The area of ​​saline-alkali cultivated land in my country accounts for a quarter of the total cultivated land area. Improving the soil physical and chemical st...

Problems solved by technology

[0003] At present, the control technology of saline-alkali soil is mainly to reduce salt and alkali components through leaching, soil cultivation, and application of organic fertilizers to improve soil nutrients. These methods can only improve soil from a single perspective, and the action time is limited, so it is difficult to completely improve the soil.
