AI Technical Summary
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.
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.
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.
