Problems solved by technology

[0004] However, the availability of trace elements in the soil generally increases under acidic conditions and decreases under alkaline conditions. Due to the influence of soil conditions, saline-alkali soils are more likely to lack trace elements
At the same time, existing studies have shown that the stress of mineral nutrients caused by the lack of trace elements can aggravate the continuous cropping obstacles of peanuts and affect the yield of peanuts.

Abstract

The invention provide a compound lactobacillus preparation capable of obviously improving a microelement absorbing rate of saline-alkali soil peanuts, and belongs to the technical field of microorganisms. Active bacteria in the compound lactobacillus preparation are prepared from Lactobacillus plantarum P-8, Lactobacillus casei Zhang and Lactobacillus plantarum CCFM8661. The compound lactobacillus preparation has an obvious effect on growth and metabolism of the saline-alkali soil peanuts, especially can improve a utilization rate of the saline-alkali soil peanuts to soil microelements, and can improve quality of the saline-alkali soil peanuts when being applied in a peanut planting process.

Description

technical field [0001] The invention relates to a lactic acid bacteria compound preparation composed of Lactobacillus plantarum P-8, Lactobacillus casei Zhang and Lactobacillus plantarum CCFM8661 and their metabolites, especially a kind of lactic acid bacteria compound preparation which can significantly improve the trace amount of peanuts in saline-alkali soil. The invention relates to a compound preparation of lactic acid bacteria with an element absorption rate, which belongs to the technical field of microbes. Background technique [0002] Trace elements are some elements that are necessary for plants but are required in a small amount. When these elements are lacking in the soil or cannot be used by plants, the plants will not grow well. The Nanjing Soil Research Institute of the Chinese Academy of Sciences conducted a survey on the content of trace elements zinc, boron, manganese, molybdenum, copper, and iron in the soil of the whole country. The results showed that th...
