Embodiment 1
[0037] A small test is carried out to illustrate the test method of the present invention. In the following examples, the soil is selected in a certain saline-alkali land in Dagang District, Tianjin. According to the saline-alkali content in the soil, saline-alkali land can generally be divided into mild saline-alkali land, moderate saline-alkali land and severe saline-alkali land. In this embodiment, mild saline-alkali land is selected for the saline-alkali land.
[0038] Soil alkalinity is maintained at the original level; the purity of the test water is double-distilled water and the total soluble organic carbon is less than 1×10 -3 g / L; the purity of the reagent is from analytical to chromatographic purity; the glass instruments used in the test are all washed with washing liquid.
[0039] A method for testing the restoration rate of saline-alkali soil, the soil restoration rate is the total restoration rate W after the restoration of the oil-containing saline-alkali soil ...
Embodiment 2
[0076] In the embodiment 2, the technical scheme is basically the same as the embodiment 1, and the difference is: in the present embodiment, the saline-alkali land selects the moderate saline-alkali land in Dagang District, Tianjin, and in this moderately saline-alkali land, the indigenous microbial strains have Algibacteragarolyticus, Halomonas halodenirificans, Novosphingobium nitrogenifigens, Halomonas halmephilum, Roseiflexus castenholzii, Salinivibrio costicola, Spirochaeta halophila, a total of 7 species of microorganisms, 5 species were added to the soil, namely: Bacillus alcalophilus, Halomonas alkaliphila, Halovibrio variabilis, Pseudomonas guineae, Rhodoligotrophos appendicifer. That is, in the present embodiment, the operations that make soil contain 12 kinds of microorganisms are: add 100mL bacterial liquid to a part of this soil (the soil of a module), the bacterial species in the bacterial liquid are respectively: Bacillus alcalophilus, Halomonas alkaliphila, Hal...
Embodiment 3
[0093] The technical scheme in Example 3 is basically the same as that in Example 1, except that the saline-alkali land in the present embodiment selects the severe saline-alkali land of Da'an City, Jilin Province, and the indigenous microorganism strains in this moderately saline-alkali land include Algibacteragarolyticus, Bacillus alcalophilus, Halomonas halodenirificans, Halovibriovariabilis , Pseudomonas guineae, Roseiflexus castenholzii, Salinivibriocosticola, a total of 7 kinds of microorganisms, 5 kinds of bacteria were added to the soil, namely: Halomonas alkaliphila, Halomonas halmephilum, Novosphingobium nitrogenifigens, Rhodoligotrophosappendicifer, Spirochaeta halophila. That is, in this embodiment, the operations for making the soil contain 12 kinds of microorganisms are: adding 100 mL of bacterial liquid to a portion of the soil (one module of soil), and the bacterial species in the bacterial liquid are: Halomonasalkaliphila, Halomonas halmephilum, Novosphingobium...
