The present invention relates to the technical field of ecological concrete slurry, and specifically to an ecological seed-carrying slurry for the slope of a mine dump, a preparation method and its application. Aiming at the special environmental characteristics of the Inner Mongolia mining area, the present invention prepares a new type of artificial aggregate containing growth domains and seeds, which is composed of a three-layer structure, each layer having a specific function, so as to achieve the purpose of promoting the germination of multi-source species, plant growth, providing nutrition and improving the soil environment. The slurry can not only effectively utilize solid waste and reduce costs, but also adopts in-situ point-type layered hole sowing to shorten the vegetation restoration cycle in the ecological restoration of the slope, greatly improve the survival rate of tree and shrub seed sources, reduce the number of watering times, save restoration costs, and reduce the workload of management. While effectively promoting vegetation restoration, it strengthens the stability of the slope, prevents soil and water loss, slows down runoff and consolidates the soil, providing an efficient and sustainable solution for the ecological restoration of green mines in Inner Mongolia.

The invention belongs to the technical field of crop fertilization, and particularly relates to a triangular fertilization method for sugar cane. Sugarcane is subjected to triangular fertilization, the sugarcane is divided into newly-planted sugarcane and perennial root sugarcane, triangular fertilization is carried out on the newly-planted sugarcane, top corner sugarcane ditch fertilization is carried out when the newly-planted sugarcane is planted, the fertilization depth is 5-10 cm, bottom corner fertilization is carried out along the middle position of a sugarcane row in the tillering stage of the sugarcane, and the fertilization depth is 30-35 cm; triangular fertilization is carried out on the perennial root sugarcanes, one-time triangular fertilization is carried out within 7 days after the sugarcanes are harvested or at the tillering stage of the perennial root sugarcanes, the fertilization depth of the 1 / 2 position of each sugarcane row is 30-35 cm, and the fertilization depth of the 1 / 4 position and the 3 / 4 position of each sugarcane row is 15-20 cm. The precise soil layer fertilization method provided by the invention has the advantages that the fertilization of sugar cane is more efficient and more environment-friendly, and farmers are helped to increase income.

The invention relates to a soil remediation and water retention microbial fertilizer, which is prepared by culturing a compound strain and optimizing nutrient substances in a culture dish, preparing the most suitable growth environment of the mixed strain, increasing the effective viable count of a microbial agent, and mixing the mixed agent with organic and inorganic fertilizers to form the compound microbial fertilizer with good water retention.

The invention provides a casein source 3D printing bio-ink and a preparation method of a biological scaffold and cell culture meat. The bio-ink is prepared from the following raw materials in parts by weight: 15.6 parts of gelatin; 2.6 parts of sodium alginate; 4.2 parts of casein; 52.5 parts of a sodium hydroxide deionized water solution with a pH value of 8; and 87.5 parts of a sterile 1 * PBS buffer solution. The ink is subjected to extrusion type 3D printing and calcium chloride crosslinking to obtain a biological scaffold; c2C12 cells are inoculated on the support, and cell culture meat is obtained through proliferation-differentiation culture. The problems that existing 3D printing bio-ink is single in performance and poor in component adaptability, a biological scaffold material is insufficient in mechanical stability, and nutritional ingredients are deficient are solved. The prepared bio-ink has excellent mechanical properties and printing adaptability, and provides key technical support for industrial preparation of cell culture meat.

The invention discloses a method for increasing the content of gamma-aminobutyric acid in traditional Chinese medicine through fermentation. The method comprises the following steps: S1, superfine grinding of raw materials; s2, performing enzymolysis treatment; s3, fermentation treatment; lactobacillus plantarum and lactobacillus reuteri are selected to be matched for fermentation. A compound enzyme system (cellulase, pectinase and hemicellulase) is added, and the enzyme addition amount is 600 U / g-1400 U / g; the content of GABA in a bacterium synergistic fermentation system is obviously higher than that of a single bacterium fermentation system. Experimental data show that the GABA content can reach 131.5 + / -0.7 [mu] mol / g under the synergistic fermentation condition for 48 h, the GABA content under the lactobacillus plantarum single bacterium fermentation condition and the GABA content under the lactobacillus reuteri single bacterium fermentation condition are 45.5 + / -1.1 [mu] mol / g and 29.9 + / -2.1 [mu] mol / g respectively, the GABA yield is increased by about 2.9-4.4 times through synergistic fermentation, and it is proved that the method can effectively promote efficient conversion and accumulation of glutamic acid into GABA.
