The invention provides a microbial preparation for improving the cultivation performance of saline-alkali land. The microbial preparation is obtained by cultivating Thiobacillus thiooxidans, Streptomyces cellulosus, Klebsiella oxytoca and Rhodotorula viscosum, and then adding potassium fulvic acid and sulfur in proportion , to form a mixture, which is used for saline-alkali land transformation, which can buffer and intelligently adjust soil pH, reconstruct soil micro-ecological communities, improve water, nutrients, and other micro-environments around crop roots, and improve crop stress resistance. The improved saline-alkali land It can be suitable for the cultivation of various crops; meanwhile, the invention also provides a preparation method of a microbial preparation for improving the cultivability of the saline-alkali land. |
