Problems solved by technology

If the underground brackish water or salt water is fully utilized, a large amount of fresh water can be saved. However, direct use of brackish water or salt water for irrigation will cause salt to accumulate on the soil surface and in various layers of the soil, resulting in soil salinization. , further causing deterioration of soil physical properties, such as poor soil aggregate structure, sticky structure, compaction, low permeability coefficient, difficult water seepage, poor aeration, slow rise in soil temperature, and high soil pH

Embodiment 1

[0016] A conditioner for inhibiting salt accumulation in soil irrigated with brackish water is prepared by the following method:

[0017] (1) Weigh 25 kg of vinegar residue and 75 kg of peat, mix well, and ferment. The fermentation steps are: add water to make the water content in the mixed material 25%, keep it moist, and ferment with a film at 25°C to 30°C or Decompose until the white hyphae are evenly distributed to make a peat-type organic matrix;

[0018] (2) take by weighing 30 kilograms of bentonite and 70 kilograms of phosphogypsum, mix and make bentonite type mineral matrix;

[0019] (3) Take by weighing 20 kilograms of ferric nitrate, 35 kilograms of potassium silicate, 20 kilograms of manganese sulfate and 25 kilograms of aluminum sulfate and mix evenly, make particle formation base;

[0020] (4) Take by weighing 30 kilograms of peat-type organic substrates made by step (1), 69 kilograms of bentonite-type mineral substrates made by step (2); The organic substrate ...

Abstract

The invention discloses a making method of amendment to inhibit brackish water irrigation soil polysalt, which comprises the following steps: (1)blending vinegar slag and grass peat or weathered lignite evenly to ferment; making the turf typed organic base or weathered lignite typed organic base; (2)mixing alta-mud and phosphogypsum to make the alta-mud typed mineral base or blending zeolite or phosphogypsum evenly to make zeolite typed mineral base; (3)blending ferric nitrate, potassium silicate, manganese sulfate and aluminium sulfate evenly to make particle forming base; (4)mixing the turftyped organic base or weathered lignite typed organic base and alta-mud typed mineral base or zeolite typed mineral base evenly; adding the particle forming base gradually to mix evenly; acceleratingthe salt ion of hazarded plant or broken soil structure to be drained out of soil body along irrigation water; fitting for soil adsorption and fixation; improving the salt ion of soil structure.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a conditioner for inhibiting salt accumulation in soil irrigated with brackish water. Background technique [0002] Factors such as the lack of fresh water resources in coastal areas have seriously affected agriculture and green ecology. Although the water quality of the brackish and salty underground water in coastal areas is poor, it is rich in resources. For example, the salinity of the deep groundwater in Tianjin Binhai New Area is about 1.0g / L. The water contains soda salt, the soluble sodium content is > 80%, and the pH is 8.0~ 8.6, the highest can reach more than 9.0; the shallow salinity is 10g / L~20g / L, the highest can reach 75.4g / L, the groundwater Cl - Accounting for 92% of the total anions, Na + It accounts for 73% of the total amount of cations. If the underground brackish water or salt water is fully utilized, a large amount of fresh water can be saved. H...
