Lactic acid bacterium preparation for promoting calendula officinalis to bloom

Abstract

The invention discloses a lactic acid bacterium preparation for promoting calendula officinalis to bloom. Active bacteria in the lactic acid bacterium preparation are composed of Lactobacillus brevis JLD715 and Lactobacillus plantarum LP28. After the two bacteria are applied in a compound mode, growth and metabolism of the calendula officinalis are obviously affected, in other words, the plant height, stem thickness, crown breadth, single-leaf maximal area and flowering phase of the calendula officinalis are promoted, beneficial influences can be generated on growth traits of the calendula officinalis, the flowering phase can be prolonged, the flower diameter can be increased, and the ornamental characteristic of the calendula officinalis can be improved.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a compound lactic acid bacteria preparation, in particular to a compound lactic acid bacteria preparation for promoting the flowering of Calendula officinalis and its application. Background technique [0002] Calendula officinalis is a plant of the genus Calendula in the family Asteraceae, which first appeared in southern Europe, Egypt and other nearby areas (Sun Man, Zhao Bing, Yao Mo, etc. Overview of Calendula Pharmacological Research [J]. Anhui Agricultural Science, 2011, 39 (34):20982-20983), has now been widely cultivated throughout the country. Calendula is not only widely used in urban landscaping, but also plays an important role in the history of medicine and botany. Calendula contains a variety of secondary substances, such as oleanolic acid, which are beneficial to the human body. Healthy, has the effect of inhibiting tumor cell growth and radiati...

Problems solved by technology

[0004] However, in recent years, the research on microbial fertilizers has mainly focused on the fields of agricultural planting and agricultural product safety, and there is little research on the ornamental quality of plants.

By searching domestic and foreign literature, there is no lactic acid bacteria preparation that promotes the growth of Calendula officinalis and improves its ornamental value.
