AI Technical Summary

Technical Problem

In the existing technology, there is little research on the use of yeast to promote the growth of plants tolerant to salt and alkali, and there are no reports on the combined use of brewer's yeast and soil microbial awakening agents, resulting in limited effects on soil improvement and crop growth.

Method used

The combined application of brewer's yeast WS04 and plant extracts is adopted. After brewer's yeast WS04 is cultured in YPD culture medium, it is combined with plant extracts to promote the growth of crops. The plant extracts contain ingredients such as deep-sea kelp and alfalfa powder to stimulate the awakening function of soil microorganisms.

Benefits of technology

Under salt stress and saline-alkali stress environments, it significantly promotes the growth of crops, improves the plant's resistance to stress, enhances the growth of roots and leaves, and improves soil fertility and photosynthetic rate.

Abstract

The invention discloses saccharomyces cerevisiae WS04 and combined application of the saccharomyces cerevisiae WS04 and a plant extracting solution, and belongs to the technical field of microorganisms. The saccharomyces cerevisiae WS04 is preserved in China General Microbiological Culture Collection Center (CGMCC) on March 6, 2025, and the preservation number is CGMCC No.33726. The saccharomyces cerevisiae WS04 disclosed by the invention can be used for preparing the saccharomyces cerevisiae. The saccharomyces cerevisiae WS04 has a growth promoting effect on crops such as cucumbers and wheat; when the plant extract is combined with the plant extract, the growth-promoting effect is achieved in non-salt-stress and salt-stress environments.
