Abstract

The invention belongs to the technical field of soil improvement, and particularly relates to a soil conditioner for repairing soda type saline-alkali soil as well as a preparation method and a use method thereof. The soil conditioner for repairing the soda type saline-alkali soil is prepared from furfural residues, composted organic fertilizer, an organic material, brown sugar, zeolite powder, lignite powder, calcium chloride, aluminum sulfate, potassium sulfate, ardealite, monoammonium phosphate, heptahydrate and cation exchange resin. Organic improvement and inorganic improvement are efficiently combined, so that the physical and chemical properties of the soda type saline-alkali soil are improved, the PH value and the salt content are reduced, the harm of alkali-causing ions is relieved, the soil substitution amount and the soil buffer property are improved, and the soil improvement and alkali reduction effects are good; the content of organic matters in the soil is increased to improve the physical property of the soil, increase the porosity of the soil, prevent and treat hardening of the soil and improve the breathability of the soil; meanwhile, the soil fertility of the sodatype saline-alkali soil is improved; the soil conditioner can be applied to soil of both a dry farmland and a paddy field and cooperates with conventional fertilization to promote growth of plants and increase the yield of crops.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a soil conditioner for repairing soda-type saline-alkali soil, a preparation method and an application method thereof. Background technique [0002] Salt composition in soda-type saline-alkaline soil is represented by Na 2 CO 3 , NaHCO 3 Mainly, it is strongly alkaline, the pH value is as high as 8.5, and the severe area exceeds 10.5, and the growth of crops is seriously hindered. Saline-alkali soil has the process of alkali process and salt surface accumulation process at the same time as salinization, with a high degree of alkalization, showing alkaline and strong alkaline reactions. Therefore, the harm of soda-type saline-alkali soil is not only high salinity, but also strong alkalinity, which is extremely difficult to control. [0003] Nowadays, the improvement of saline-alkali soil is mostly based on the characteristics of "salt comes with water, sal...
