Example Embodiment

[0027] Example 1

[0028] A lactic acid bacteria compound preparation for fertilization in saline-alkali soil is prepared according to the following steps:

[0029] (1) Inoculate Lactobacillus plantarum, Lactobacillus rhamnosus, and Lactobacillus bulgaricus respectively in MRS medium, culture at 35-37℃ for 18-24 hours, and subculture 2-3 times to obtain the bacteria The culture was then put into a fermentor, and subjected to secondary fermentation at 28°C at 5% inoculum for 48 hours, centrifuged to collect the bacterial sludge, and vacuum freeze-dried to obtain the corresponding bacterial powder;

[0030] (2) Inoculate the yeast in YPD liquid medium, culture it at a constant temperature at 25-30℃, 150rpm for 18-24 hours, then put it into the fermenter, and carry out the second stage at 28℃ according to the inoculation amount of 5% Fermentation for 48h, centrifugation to collect the sludge, and vacuum freeze-drying to obtain yeast powder;

[0031] (3) Inoculate the original species of...

Abstract

The invention discloses a lactic acid bacteria compound preparation for fertilizing saline-alkali soil. The lactic acid bacteria compound preparation comprises lactobacillus plantarum, lactobacillus rhamnosus, lactobacillus bulgaricus, saccharomyces boulardii and bacillus subtilis, and the mass ratio of the lactobacillus plantarum to the lactobacillus rhamnosus to the lactobacillus bulgaricus to the saccharomycetes to the bacillus subtilis is 2: (0.5-1): (1-1.5): (1-1.5): (0.5-1). The lactic acid bacteria compound preparation can effectively improve the porosity and water retention of soil, reduce the soluble salt content of the soil and adjust the pH value of the soil, so that insoluble phosphorus and potassium in the soil are converted into available phosphorus and potassium which can beutilized by crops, and the yield of the crops is increased.

Description

technical field [0001] The invention belongs to the field of soil conditioning, in particular to a lactic acid bacteria compound preparation for fertilizing saline-alkali land and a preparation method thereof. Background technique [0002] At present, soil salinization has become an agricultural issue of global concern. The physical and chemical properties of saline-alkali soil are mainly manifested as low soil fertility, lack of nutrient elements, soil compaction, low soil microbial content, and poor permeability. It not only restricts the healthy development of agriculture, but also brings about problems such as soil erosion, soil erosion, and land desertification. The formation of saline-alkali land is due to the redistribution of soluble salts in the soil, resulting in the accumulation of salt on the soil surface, which eventually exceeds the normal value and makes the soil salinized. The reasons affecting the redistribution of soil salinity are mainly divided into int...
