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.

The invention provides a factory-like cuttage breeding method for tetrazygium mongolicum, and belongs to the technical field of plant cuttage breeding. The factory-like cuttage breeding method for the tetracalamus mongolicus comprises the steps of building a factory-like greenhouse, preparing a seedling raising field, selecting and processing cuttings, performing cuttage and performing management after cuttage. The seedling raising land serves as a cutting seedbed, and a seedbed matrix is river sand with the particle size being 4-6 mm or clean sand with the particle size being 2-4 mm or vermiculite with the particle size being 2-3 mm The cuttings are the cuttings of which the middle upper parts of current-year or annual branches are grey white, yellow white or yellowish brown, and exogenous hormone treatment is carried out on cuts of the cuttings; the exogenous hormones comprise 30%-70% of indoleacetic acid, 0-20% of indolebutyric acid, 15%-25% of naphthylacetic acid and 10%-40% of amino acid water-soluble fertilizer. By selecting and preparing the cutting medium and the cuttings and screening the exogenous hormones, the rooting survival rate of the cuttage of the tetrazygium mongolicum can be obviously improved. By means of the method, the survival rate of cuttage of the quadrangle trees reaches 90% or above, and the overall preservation rate reaches 70% or above.
