The application discloses a method for rapidly screening breeding parents of Babylonia areolata based on shell color phenotype, and the specific steps are as follows: collecting adult Babylonia areolata; dividing the adult Babylonia areolata into a dark color group and a light color group according to shell color, wherein the dark color group is red brown to dark red brown individuals, and the light color group is white to yellow brown individuals; using differential morphological indexes for the Babylonia areolata in different shell color groups to accurately screen Babylonia areolata breeding parents: for the dark color group, shell width is greater than or equal to 58 mm, body spiral layer width is greater than or equal to 45 mm, and shell mouth height is greater than or equal to 65 mm; and for the light color group, body spiral layer width is greater than or equal to 45 mm, shell mouth height is greater than or equal to 65 mm, shell height is greater than or equal to 91 mm, and shell width is greater than or equal to 55 mm. The parent with high body quality and high meat yield potential can be screened in vivo, and through comparison of offspring cultivation of the screening group and the control group, it is proved that the screening method can significantly improve the genetic gain (17.9-21.1%) of the target traits, and has good breeding application value.

U I T T R E K S E L The present invention belongs to the field of agricultural microbial control technology, and specifically relates to a growth—promoting and disease—preventing compound microbial inoculant, a preparation method and an application thereof. The compound microbial inoculant specifically includes microbial powder, growth auxiliary materials, and. a desiccant. The microorganisms include Talaromyces flavus, Trichoderma harzianum, Bacillus velezensis, Bacillus licheniformis, and Brevibacillus laterosporus. Through the synergistic effect of multiple microbial strains, the compound microbial inoculant of the present invention enhances the control effect against Verticillium wilt pathogens, and overcomes the shortcomings of a single biocontrol microbe, such as a single biocontrol mechanism, poor environmental adaptability, inability to colonize in soil for a long time, and unstable control effect. Furthermore, the compound microbial inoculant of the present invention can increase the yields of cotton and pepper, and improve the fiber quality of cotton. The present invention provides scientific and technological support and decision-making services for realizing green, environmentally friendly, cost—saving, and efficiency-increasing modern agriculture.
