The application discloses a plant-source bio-growth-promoting synergistic fertilizer and a preparation method thereof. The fertilizer is prepared by compounding plant-source composite growth-promoting substances, a composite microbial flora and a carrier material in a specific mass ratio. The plant-source composite growth-promoting substances are prepared by solid-state fermentation and extraction of gynostemma pentaphyllum, astragalus and acanthopanax. The composite microbial flora contains brazilian nitrogen-fixing spirillum, fluorescent pseudomonas and brevibacillus brevis, and is embedded and fixed by using kappa-carrageenan microcapsules containing biochar nanoparticles. The carrier is lignosulfonate-modified nano-attapulgite. The application also provides a corresponding preparation method. The granular fertilizer is finally prepared through steps of activating the strains by a composite activation solution, embedding by microencapsulation and carrier loading granulation. The fertilizer combines the synergistic effect of plant-source active substances and functional microorganisms, significantly improves the activity of the flora and the field colonization capacity, and can effectively promote plant growth, improve crop yield and quality.

This invention belongs to the field of environmental disinfectant technology, specifically relating to a disinfectant for animal husbandry environments and its preparation method. This invention induces Bacillus subtilis fermentation through a compound extract of hawthorn, codonopsis, and astragalus. The three extracts synergistically upregulate the expression of genes related to antibacterial lipopeptide synthesis, significantly enhancing the antibacterial potency of the fermentation broth. The highly active antibacterial fermentation broth is then incorporated into a sodium alginate-xanthan gum composite gel network. Utilizing the slow oxidation properties of ascorbic acid under environmental humidity and oxygen, the gel network gradually undergoes proton dissociation, achieving a stable and long-lasting release of the antibacterial active ingredients. Simultaneously, xanthan gum swells upon contact with water to form a highly viscoelastic gel film, significantly enhancing the disinfectant's adhesion and retention capacity on humid surfaces. The resulting disinfectant possesses comprehensive properties including high antibacterial activity, long-lasting action, and strong environmental adhesion. The preparation process is simple and controllable, making it suitable for large-scale application in livestock farming environments.

The application provides an integrated ridging and mulching and hole planting combined operation device, relates to the astragalus membranaceus planting technical field and comprises a supporting assembly. A rotary cultivator, a pipeline laying assembly, a mulching film laying assembly, a film pressing assembly, a ridge forming assembly and a hole planting assembly are sequentially arranged on the supporting assembly from front to back. The front end of the supporting assembly is used for connecting an agricultural tractor, so that rotary tillage, pipeline laying, mulching film laying, film pressing, ridging and hole planting operations are sequentially completed when the integrated machine is towed by the agricultural tractor. The rotary cultivator, the pipeline laying assembly, the mulching film laying assembly, the film pressing assembly, the ridge forming assembly and the hole planting assembly are integrated and installed on the same supporting assembly, so that the rotary tillage, the pipeline laying, the mulching film covering, the film pressing, the ridging and the hole planting operations can be sequentially completed once the device enters the soil. Compared with the traditional multiple step operations, the number of times of entering the soil is reduced, the soil compaction degree is reduced, the overall operation efficiency is improved, and the labor cost is saved.

The application discloses a double-crank staggered shaking sieve type deep-rooted crop harvester and relates to the technical field of deep-rooted crop harvesting. The double-crank staggered shaking sieve type deep-rooted crop harvester comprises a rack, a double-crank shaking sieve, a transmission system, a depth limiting wheel, a wing-shaped soil separating guard and a digging shovel. The double-crank shaking sieve comprises a double-crank driving mechanism and a plurality of shaking sieve bar assemblies. The bar assemblies are staggered in height, and the double-crank driving mechanism drives the adjacent bar assemblies to staggered reciprocating shake with a phase difference of 180 degrees, so that the thick soil is forced to shear and tear, and the root-soil separation efficiency is improved. The phase staggered motion offsets the alternating inertia force, and the whole machine runs stably, has low energy consumption and high reliability. The front wing-shaped soil separating guard separates the soil and the stones and protects the transmission components. The application can efficiently harvest deep-rooted stem crops such as liquorice and astragalus membranaceus and can also be compatible with shallow-rooted stem crops such as potatoes and peanuts, has high universality and is suitable for large-scale mechanized harvesting of root crops.
